Actions Documentation

Activate()

This action returns a default behavior for this paricular control. Some controls do nothing by default, like a TextBox that responds to different kinds of input. Others, however, have default behaviors, like a Button or a MenuItem. If there is no default behavior, this action returns undefined.

Activate(Libraries.Interface.Events.BehaviorEvent event)

Parameters

Add(integer index, Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one, storing the added Item2D at a specific index in the internal array.

Example Code

use Libraries.Interface.Item2D

        Item2D parentItem
        Item2D child
        parentItem:Add(0, child)

Parameters

Add(Libraries.Interface.Item2D newItem)

This action adds a different Item2D into this one. This makes a few things happen. 1. The added item will get this item as its parent. 2. The added item's x and y coordinates will become relative to this Item. 3. Most actions on this Item will also affect the added Item.

Example Code

use Libraries.Interface.Item2D

        Item2D parentItem
        Item2D child
        parentItem:Add(child)

Return

boolean:

BeginCollision(Libraries.Interface.Item item)

This action is used to indicate that two items have just begun colliding. When two Items collide, the BeginCollision action should be called on both of them, with the other item passed as a parameter to the action. Note that this action does nothing by default, but classes that inherit from Item may override it.

Example Code

use Libraries.Interface.Item

        Item collider1
        Item collider2
        collider1:BeginCollision(collider2)
        collider2:BeginCollision(collider1)

Parameters

BeginMouseOver()

Whether or not this Control should automatically be laid out during the next Update loop.

CanRotate(boolean flag)

This action gets the position of the center of this item in global (world) coordinates.

Parameters

CancelBehaviors()

This action stops all behaviors this Item is following without finishing them.

ClickedMouse()

This action obtains the Input Table from this control, copies it, assigns it a group name, sets the control to use the new input table, and then adds it to the global input table hash table.

Example Code

use Libraries.Game.Game
        use Libraries.Interface.Controls.TextBox
        use Libraries.Game.InputTable

        class Main is Game

This action sets the mass, mass moment of inertia, and how the 2D item should move (via linear velocity) to be at the desired location.

Return

boolean:

Compare(Libraries.Language.Object object)

This action compares two object hash codes and returns an integer. The result is larger if this hash code is larger than the object passed as a parameter, smaller, or equal. In this case, -1 means smaller, 0 means equal, and 1 means larger. This action was changed in Quorum 7 to return an integer, instead of a CompareResult object, because the previous implementation was causing efficiency issues.

Example Code

Object o
        Object t
        integer result = o:Compare(t) //1 (larger), 0 (equal), or -1 (smaller)

Parameters

Return

integer: The Compare result, Smaller, Equal, or Larger.

This action computes the distance of the passed point from the collision shape attached to this item. This action is used internally and users should not need to use this action.

Parameters

Return

number: The distance of the point from the collision shape of this item

Contains(number containsX, number containsY)

This action tests if a point in global x,y coordinates is contained inside this Item2D. The global coordinates are considered to be the x and y coordinates of this Item plus its offsetX and offsetY values.

Example Code

use Libraries.Interface.Item2D

        Item2D item
        item:SetPosition(50, 50)
        item:SetWidth(100)
        item:SetHeight(50)

Parameters

Return

boolean: Whether or not the point is contained in this Item.

CopyAndActivateInputTable(text name)

This action obtains the Input Table from this control, copies it, assigns it a group name, sets the control to use the new input table, and then adds it to the global input table hash table.

Example Code

Parameters

DestroyNodes(Libraries.Game.Collision.BroadphaseCollision2D broadphase)

This action destroys the nodes for this item for the broadphase collision, essentially removing it from the collision detection system. This action is used internally and users should not need to use this action.

Parameters

Dispose()

This action is used to free up any additional memory that is being used by this Item for purposes such as graphics. Note that the Item class doesn't have any extra memory that needs to be released with this action, but some classes which inherit from Item, such as Libraries.Game.Graphics.Drawable, do.

DisposeAll()

This action is used to call Dispose on this Item and on the entire children hierarchy of this Item.

DisposeChildren()

This action is used to call Dispose on the entire children hierarchy of this Item. This will not call Dispose on this Item.

Draw(Libraries.Game.Graphics.Painter2D painter)

The Draw action is used to perform custom drawing on this Item and its children. This is only called during the Game engine's draw phase if this Item has enabled custom drawing via the SetCustomDrawing action. This is an advanced feature, and shouldn't be used by most users. If custom drawing is enabled, this action should be overriden -- if it isn't, the Item will attempt to provide default rendering for itself, its view, and its children, without regard to depth buffering. This action is responsible for instructing the provided Painter on how to draw this item, the view, and its children, and in what order to do so.

Parameters

Empty()

This action will remove all items from this item's children hierarchy. Note that this will not empty the hierarchies of the contained Items.

Example Code

EmptyAll()

This action will call Empty on the entire children hierarchy of this item, and then empty this item as well.

EmptyChildren()

This action is used to call Empty on all children contained in this item's children hierarchy. This will not empty the children of this item.

EmptySelectionListeners()

EnablePhysics(boolean flag)

This action enables physics for this item. Passing true turns on physics for this item while passing false turns off physics for this item.

Example Code

Example Code

use Libraries.Interface.Item

        Item collider1
        Item collider2
        collider1:FinishCollision(collider2)
        collider2:FinishCollision(collider1)

Parameters

FlipX()

This action will flip the Item2D across the X-axis. This flip is represented by the internal vertices of the Item2D. For classes that inherit from Item and can draw on the screen, this will flip the drawn image on the screen.

Example Code

GetDefaultFont()

This action obtains the default font for this control. This allows individual controls to customize their default font properties on a per control basis. By default, the system asks for the default system font name on a per control basis, then loads that font and returns it. Font loading is shared, so loading many fonts of the same type and size is not particularly expensive and can be done without much concern for memory requirements.

Example Code

use Libraries.Interface.Controls.TextBox

GetDensity()

This action applies a linear impulse to this item at the passed point. The impulse is in kilogram units per second. This immeadietly modifies the linear velocity of this item. The point is the screen coordinates where the impulse will be applied. If the point is not the center of the item, then the angular velocity of this item will also be modified. Physics must be enabled on this item before using this action.

Example Code

use Libraries.Interface.Item2D
    use Libraries.Compute.Vector2

    Item2D item
    Vector2 impulse
    Vector2 point

This action returns an Iterator containing all of the FocusListeners that have been added to this Item using the AddFocusListener action.

Return

Libraries.Containers.Iterator: An iterator containing all of the registered FocusListeners.

GetFont()

This action returns the Font being used by this Control. How this Font is used varies between Controls, and in some cases the Control will ignore it entirely (for example, ScrollPanes), but typically this sets the font that's used for the default label on many Controls, such as Buttons. If the Font is undefined, many Controls will omit their default label.

Hide()

This action is used to indicate that an Item and all Items that were added to it should not be visible on the screen. Note that the Item class on its own cannot be drawn on the screen, but classes that inherit from it such as Libraries.Game.Graphics.Drawable can be. By default, Items are considered visible.

Example Code

use Libraries.Interface.Item

        Item item
        item:Hide()

IsAcceptingMouseInput()

This action returns whether or not this Item accepts mouse input. If the value is true, this will intercept incoming mouse events, triggering any related MouseListeners and InputSets and preventing the mouse event from propagating to other Items on the Layer. The default value is true.

Return

boolean: True if this Item can receive mouse events, or false otherwise.

IsAccessibleParent()

This action returns the nearest parent object that is accessible. This can be anything that the programmer wants to be accessible, from user interface components in a 2D interface to 3D components relative in 3-space on screen. By default, items have no accessible parent and are self-contained, but user interface components normally override the behavior so that controls can be logically nested within each other. attribute: returns Item

Return

boolean:

IsClipping()

The IsClipping action returns true if pixel clipping is enabled, or false if it is disabled. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Return

boolean: Whether or not pixel clipping is enabled for this Item.

IsCollidable()

This action determines whether this item is collidable.

Example Code

use Libraries.Game.Graphics.Drawable

    circle:SetCollidable(true)
    boolean result = circle:IsCollidable

Return

boolean: True if this item is collidable, false otherwise

IsCustomDrawing()

The IsCustomDrawing action returns whether or not this Item is directly managing how itself and its children are drawn. When this value is true, the Item is responsible for determining its rendering via the Draw(Painter2D) action -- if this action isn't overridden, the Item and its children won't be drawn. This is an advanced feature only necessary for complex custom components, and most users will not need to use this functionality.

Return

boolean: Whether or not this Item is currently using custom drawing rules.

IsDepressed()

Whether or not this button is currently depressed, e.g. by a mouse click or touch event.

Return

boolean:

IsEmpty()

This action returns whether or not any items are contained in this Item.

Example Code

use Libraries.Interface.Item2D

        Item2D parentItem
        Item2D child1
        parentItem:Add(child1)
        boolean wasEmpty = parentItem:IsEmpty()

Return

boolean:

IsFastMoving()

    item:SetHeight(100)
    item:EnablePhysics(true)
    item:SetAngularVelocity(0.1)

Return

boolean:

IsFlippedX()

This action will return if the Item2D is currently flipped across the x-axis.

Example Code

use Libraries.Interface.Item2D
        
        Item2D myItem
        myItem:FlipX()
        boolean flip = myItem:IsFlippedX()

Return

boolean:

IsFlippedY()

        Item2D myItem
        myItem:FlipY()
        boolean flip = myItem:IsFlippedY()

Return

boolean:

IsFocusable()

This action returns whether or not the Item can currently receive focus. This property can be set with SetFocusable().

Return

boolean:

IsFocused()

The IsFocused action determines if this Item is currently focused, returning true if it is, or false if it is not.

Return

boolean:

IsNonResponsive()

This action gets the number of broadphase nodes this item has. This action is used internally and users should not need to use this action.

Return

boolean: The number of broadphase nodes attached to this item

IsOnLayer()

This action returns true if the item has been added to a Layer, or false otherwise.

Return

boolean: True if the item is on a Layer, or false otherwise.

IsResponsive()

This action sets this item to be collidable. Passing true turns on collision for this item while passing false turns off collision for this item.

Example Code

use Libraries.Game.Graphics.Drawable
    
    Drawable circle
    circle:LoadFilledCircle(30)
    circle:SetCollidable(true)

Return

boolean:

IsRotationAllowed()

This action determines whether physics is currently enabled for this item.

Example Code

Return

boolean:

IsUnmovable()

This action creates the nodes for this item for the broadphase collision. This action is needed in order to add the item to the collision detection system. This action is used internally and users should not need to use this action.

Return

boolean:

LoadGraphics(Libraries.Interface.Layouts.LayoutProperties properties)

This action is used to load the graphical components of the Control. This is handled automatically by the Game engine as needed, and most users shouldn't need to use this action directly.

Parameters

Parameters

NeedsLayout()

This action returns whether or not the Control is in need of laying out by its container (or the parent Layer2D, if no container Control exists).

Return

boolean:

NotifyControlActivationListeners(Libraries.Interface.Events.ControlActivationEvent event)

The FILL layout style will attempt to fill the remaining width or height of the container with this Control. Note that this is only effective if the container's dimensions are already known independently of this element's size -- for example, a FILL layout can't be effectively used if the container's layout style is FIT_CONTENTS.

Parameters

NotifySelectionListeners(Libraries.Interface.Events.SelectionEvent event)

This action will notify all SelectionListeners which have been added to the Control of the given SelectionEvent.

Parameters

PrepareVertices()

Checks to see if the Item2D's internal vertices are up to date, and updates them if they are not. This is used primarily internally to ensure that the item's vertices are properly aligned before use, e.g. to project an image on the screen at the coordinates of the vertices. Most users will never need to use this action directly.

ProcessMouseEvent(Libraries.Interface.Events.MouseEvent event)

This action takes a mouse event and handles it. It will first test to see if the mouse event took place within the bounds of this Item. If so, it will notify any MouseListeners of the event. If the event was not contained within this Item, or if there are no MouseListeners on this Item, the Item will ask its parent Item to process the mouse event, if there is a parent.

Example Code

use Libraries.Interface.Item2D
        use Libraries.Interface.Events.MouseEvent
        use Libraries.Interface.Events.MouseListener
        Item2D myItem
        MouseListener listener
        myItem:AddMouseListener(listener)
        MouseEvent event
        event:eventType = event:CLICKED_MOUSE
        myItem:ProcessMouseEvent(event)

Parameters

ProcessTouchEvent(Libraries.Interface.Events.TouchEvent event)

FIX ME: Needs comments

Parameters

QueueForDrawing(Libraries.Game.Graphics.Painter2D painter)

This action is used to draw this Item on the screen, and then draw all of the Item's children hierarchy on the screen. Note that Items themselves can not be drawn, but some classes that extend the Item class, such as the Libraries.Game.Graphics.Drawable class, can be. To see how they draw, see their documentation.

Parameters

ReleasedMouse()

This action obtains the Input Table from this control, copies it, assigns it a group name, sets the control to use the new input table, and then adds it to the global input table hash table.

Example Code

use Libraries.Game.Game
        use Libraries.Interface.Controls.TextBox
        use Libraries.Game.InputTable

        class Main is Game
            action Main
                StartGame()
            end

            action CreateGame
                TextBox box
                InputTable copy = box:CopyAndActivateInputTable("New Group")
            end

            action Update(number seconds)
            end
        end

Remove(integer index)

This action adds a different Item2D into this one. This makes a few things happen. 1. The added item will get this item as its parent. 2. The added item's x and y coordinates will become relative to this Item. 3. Most actions on this Item will also affect the added Item.

Example Code

use Libraries.Interface.Item2D

        Item2D parentItem
        Item2D child
        parentItem:Add(child)

Parameters

Return

Libraries.Interface.Item2D:

Remove(Libraries.Interface.Item2D item)

This action adds a different Item2D into this one, storing the added Item2D at a specific index in the internal array.

Example Code

use Libraries.Interface.Item2D

        Item2D parentItem
        Item2D child
        parentItem:Add(0, child)

Parameters

Return

boolean:

RemoveControlActivationListener(Libraries.Interface.Events.ControlActivationListener listener)

The FIT_CONTENTS layout style will calculate this Control's dimensions as the combined total dimensions of its children elements. Because children elements often need to have some concrete information about the parent's dimensions, it's recommended to only use this in one of the two directions (horizontally or vertically) for the Control. For example, FlowLayouts work well with elements with a predetermined STANDARD horizontal layout style and using FIT_CONTENTS for the vertical layout style.

Parameters

RemoveFocusListener(Libraries.Interface.Events.FocusListener listener)

This action removes a FocusListener from the Item. The listener will no longer receive notification if the Item gets a FocusEvent.

Example Code

use Libraries.Interface.Item
        use Libraries.Interface.Events.FocusListener
        Item myItem
        FocusListener listener
        myItem:AddFocusListener(listener)
        myItem:RemoveFocusListener(listener)

Parameters

RemoveLayoutProperties(Libraries.Interface.Layouts.LayoutProperties properties)

Parameters

This action requests that this Control should be laid out by its container (or the Layer2D if there is no containing Control) during the next Update.

RequireSimulation(boolean flag)

This action sets the y-component of this item's linear velocity in units per second. Physics must be enabled on this item before using this action.

Example Code

use Libraries.Interface.Item2D

    Item2D item

    item:SetWidth(100)
    item:SetHeight(100)
    item:EnablePhysics(true)
    item:SetLinearVelocityY(100)

Parameters

ResetLayoutFlag()

This action is used to indicate that the Control no longer needs to be laid out. This is called internally by the system as needed, and shouldn't be necessary for most users.

ResetMass()

This action sets the mass, mass moment of inertia, and how the 2D item should move (via linear velocity) to be at the desired location.

Resize()

The Resize action is used to recalculate the size and position of Controls that are being controlled by a Layout. Calling Resize on an Item2D won't have a direct effect on it, but if the Item's children hierarchy contains any Controls, those Controls will be resized.

Rotate(number degrees)

Rotates this Item2D by the given number of degrees. This will also rotate all Items in the children hierarchy of this Item.

Example Code

use Libraries.Interface.Item

        Item myItem

        myItem:Scale(1.1, 0.9)

Parameters

ScaleFromCenter(number amount)

This action will multiply the current scaling value by the given number. A parameter of 0 or less will be ignored. This action will increase or decrease the scale of the object from the center, and update the Item's x,y coordinates to reflect the new bottom-left corner of the Item.

Example Code

use Libraries.Interface.Item2D
        
        Item2D myItem
        myItem:SetSize(100, 200)

        myItem:ScaleFromCenter(1.1)

Parameters

ScaleFromCenter(number xAmount, number yAmount)

This action will multiply the current scaling values of the x and y planes by the given number. A parameter of 0 or less will be ignored. This action will increase or decrease the scale of the object from the center, and update the Item's x,y coordinates to reflect the new bottom-left corner of the Item.

Example Code

use Libraries.Interface.Item2D
        
        Item2D myItem
        myItem:SetSize(100, 200)

        myItem:ScaleFromCenter(1.1, 0.9)

Parameters

SelectByFirstLetters(text firstLetter)

This action selects an item in the Control using first letter navigation, if the Control supports it. If the Control doesn't support first letter navigation, this will do nothing.

Parameters

SetAcceptsMouseInput(boolean accepts)

This action sets whether or not this Item accepts mouse input. If set to true, this will intercept incoming mouse events, triggering any related MouseListeners and InputSets and preventing the mouse event from propagating to other Items on the Layer. The default value is true.

Parameters

SetAccessibilityCode(integer newAccessibilityCode)

This action changes the accessibility code for this Item. This should be done with care because setting the accessiblity code to the incorrect type can cause accessibility to stop functioning or, in some cases, cause the program to crash.

Parameters

SetAngularDamping(number angularDamping)

This action gets the rotational inertia of this item. The inertia is in kilogram units squared.

Example Code

use Libraries.Interface.Item2D

    Item2D item

        Item myItem
        myItem:SetCenterY(65)

Parameters

SetChildrenProcessingMouseEvents(boolean shouldProcess)

The SetChildrenProcessingMouseEvents action is used to set whether or not children items should receive mouse events if this Item is using custom drawing. This affects only custom drawing Items -- if the Item isn't drawing, children objects will always receive the mouse events first. This value is false by default. This is an advanced feature only necessary for complex custom components, and most users will not need to use this.

Parameters

SetClipCoordinates(Libraries.Game.Graphics.Painter2D painter)

This action sets the clipping coordinates of the given painter to respect the coordinates of this Item (if it's clipping) as well as any clipping being performed by parent Items. This action is called automatically by the Game engine as necessary, and most users will never need to use this action directly.

Parameters

SetClipping(boolean clip)

The SetClipping action is used to enable or disable clipping. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Parameters

SetCollidable(boolean flag)

This action sets this item to be collidable. Passing true turns on collision for this item while passing false turns off collision for this item.

Example Code

use Libraries.Game.Graphics.Drawable
    
    Drawable circle
    circle:LoadFilledCircle(30)
    circle:SetCollidable(true)

Parameters

SetCollideWithChildren(boolean flag)

This action gets the position of the item in physics space from the previous frame. This action is used internally and users should not need to use this action

Parameters

SetCollisionGroupFlag(boolean flag)

This action sets the total torque on this item. The units are kilogram units squared per second per second. This action should be used to set the total torque on this item. If we want to apply a torque to this item, we should use the ApplyTorque actions instead. Physics must be enabled on this action before using this action.

Example Code

use Libraries.Interface.Item2D

    Item2D item

    item:SetWidth(100)
    item:SetHeight(100)
    item:EnablePhysics(true)
    item:SetTorque(200)

Parameters

SetCollisionGroupIndex(integer index)

This action sets the total force on this item. The units are kilogram units per second per second. This action should be used to set the total force on this item. If we want to apply a force to this item, we should use the ApplyForce actions instead. Physics must be enabled on this item before using this action.

Example Code

This is an action used internally by the physics system to keep track of the collisions with this item in a linked list structure. This action sets the head of the linked list of collisions to the passed CollisionEdge2D object. This action is used internally and users should not need to use this action.

Parameters

SetCustomDrawing(boolean isCustom)

The SetCustomDrawing action is used to indicate that this Item wants to directly manage how itself and its children are drawn. When this is set to true, the Item must be responsible for determining this rendering via the Draw(Painter2D) action -- if this action isn't overridden, the Item and its children won't be drawn. This is an advanced feature only necessary for complex custom components, and most users will not need to use this functionality.

Parameters

SetDensity(number density)

This action applies an angular impulse to this item. The units are in kilogram units squared per second. This modifies the angular velocity of this item. Physics must be enabled on this item before using this action.

This action is used internally by the physics system to set the position of this item in the physics world. This action is used internally and users users should not need to use this action.

Parameters

SetTransform(Libraries.Game.Collision.PhysicsPosition2D transform)

This action sets the position of the item in physical space. This action is used internally and should not be used by users to set the position of this item on the screen.

Parameters

SetTransform0(Libraries.Game.Collision.PhysicsPosition2D transform)

This action sets the position of the item in physics space from the previous frame. This action is used internally and users should not need to use this action.

Parameters

SetUnfocusedSelectionColor(Libraries.Game.Graphics.ColorGroup color)

Parameters

SetUnmovable()

This action destroys the nodes for this item for the broadphase collision, essentially removing it from the collision detection system. This action is used internally and users should not need to use this action.

SetUpdateTransform(boolean flag)

This item is used to test whether a passed point is on the collision shape of this item.

Example Code

use Libraries.Interface.Drawable
    use Libraries.Compute.Vector2

    Drawable circle
    circle:LoadFilledCircle(30)
    circle:SetPosition(350, 400)
    Vector2 point
    point:Set(365, 410)
    boolean result = circle:TestPoint(point)

Parameters

SetVerticalLayoutMode(integer mode)

The GetVerticalLayoutMode is used to determine how the height of a Control is calculated. It should be one of the following constants: STANDARD, which will calculate the height as a set number of pixels plus a percentage of the container's height. FILL, which will make the height fill the remaining height of the container. FIT_CONTENTS, which will calculate the height to fit the children contents. FIT_FONT, which will fit the height of the Control to the line height of the Font set in this LayoutProperties.

Parameters

SetView2D(Libraries.Interface.Views.View2D content)

The IsClipping action returns true if pixel clipping is enabled, or false if it is disabled. If it is enabled, when the Item and its children are drawn as part of the QueueForDrawing action, any pixels that would be drawn outside of the unrotated dimensions of the Item are not rendered. In other words, the Item will only draw inside the exact rectangle formed by its x, y position and its width and height.

Parameters

SetWidth(number newWidth)

This action will set the width of the Item2D.

Example Code

use Libraries.Interface.Item2D
        Item2D myItem
        myItem:SetWidth(50)

Parameters

SetX(number setX)

This action sets the X coordinate of the Item.

Example Code

use Libraries.Interface.Item2D
        Item2D myItem
        myItem:SetX(35.0)

Parameters

SetY(number setY)

This action sets the Y coordinate of the Item.

Example Code

use Libraries.Interface.Item2D
        Item2D myItem
        myItem:SetY(210.0)

Parameters

SetZ(number setZ)

This action sets the Z value of the Item2D. For Item2D, the z value is used during layer sorting to determine ordering, where lower z values will be placed first.

Example Code

use Libraries.Interface.Item2D
        Item2D myItem
        myItem:SetZ(3)

Parameters

ShouldCollide(Libraries.Interface.Item2D otherItem)

get the old target global center of the obje

Parameters

Return

boolean:

Show()

This action is used to indicate that an Item and all Items that were added to it should be visible on the screen. Note that the Item class on its own cannot be drawn on the screen, but classes that inherit from it such as Libraries.Game.Graphics.Drawable can be. By default, Items are considered visible.

Example Code

use Libraries.Interface.Item

        Item item
        item:Show()

Simulate(boolean flag)

This action sets the linear velocity of this item in units per second. Physics must be enabled on this item before using this action.

Example Code

use Libraries.Interface.Item2D
    use Libraries.Compute.Vector2

    Item2D item
    Vector2 velocity

    item:SetWidth(100)
    item:SetHeight(100)
    item:EnablePhysics(true)
    velocity:Set(100, 0)
    item:SetLinearVelocity(velocity)

Parameters

SynchronizeNodes()

This action is used to syncronize the item's position in physics space with its position in the tree used for broadphase collision. This action is used internally and users should not need to use this action.

SynchronizeTransform()

This action is used to update this items position in physics space after physics solving is finished for this item. This action is used internally and users should not need to use this action.

TestPoint(Libraries.Compute.Vector2 point)

This item is used to test whether a passed point is on the collision shape of this item.

Example Code

use Libraries.Interface.Drawable
    use Libraries.Compute.Vector2

    Drawable circle
    circle:LoadFilledCircle(30)
    circle:SetPosition(350, 400)
    Vector2 point
    point:Set(365, 410)
    boolean result = circle:TestPoint(point)

Parameters

Return

boolean: True if the passed point is on the collisoin shape, false otherwise

Update(number secondsSinceUpdate)

This action updates the item. It takes a number parameter that should indicate how many seconds have passed since the last time this action was called. This action does nothing in the Item class, but any class that inherits from Item may override it.

Example Code

use Libraries.Interface.Item
        use Libraries.System.DateTime
        
        class Main is Item

            action Main
                // We'll use a DateTime object to count seconds.
                DateTime time
                number currentTime = time:GetEpochTime()
                number newTime = 0

                repeat while GetX() < 300
                    // Check what the time is now.
                    newTime = time:GetEpochTime()

                    // Calculate how many seconds have passed, then call Update.
                    Update( (newTime - currentTime)/1000 )

                    // Store the old time.
                    currentTime = newTime
                end
            end

            // Our update action will move our Item to the right at 200 units a second.
            action Update(number secondsSinceUpdate)
                SetX(GetX() + 200 * secondsSinceUpdate)
            end
        end

Parameters

UpdateAll(number seconds)
