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.

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

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.

Return

Libraries.Game.Graphics.Font: The Font being used for this Control.

Parameters

RequestLayout()

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)

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.

RestoreLastFocus()

The RestoreLastFocus action is used internally by the Menu system to restore focus to the last Item that had it before the Menu was focused. This action is called automatically as needed by the system, and users should not have to call it manually.

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:Rotate(65)

Parameters

Scale(number amount)

This action will multiply the current scaling value by the given number. A parameter of 0 or less will be ignored.

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.

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)

Parameters

SetDescription(text newDescription)

This action sets the internal description of the Item.

This action sets the Font to be 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.

Parameters

SetFontColor(Libraries.Game.Graphics.Color color)

Parameters

SetFontSize(integer size)

This action sets the base Font size to be used by this Control, if the Control uses a Font.

Parameters

        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)

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)

Parameters

UpdateTransformAngle()

UpdateTransformX()

UpdateTransformY()
