Actions Documentation

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.

Parameters

Example

use Libraries.Interface.Item2D

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

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.

item:ApplyTorque(350)

AreChildrenProcessingMouseEvents()

This action returns whether or not this Item is allowing its children to receive mouse events if the Item is custom drawing. If the Item isn't using custom drawing, this value is irrelevant -- children objects always receive mouse events before the parent if the parent isn't performing custom drawing.

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.

Parameters

Example

use Libraries.Interface.Item

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

BeginMouseOver()

CanRotate(boolean flag)

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

Parameters

  • boolean flag

CancelBehaviors()

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

ClickedMouse()

CollideWithChildren()

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.

Parameters

Return

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

Example

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

ComputeDistance(Libraries.Compute.Vector2 point, integer childIndex, Libraries.Compute.Vector2 normalOut)

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

  • Libraries.Compute.Vector2: The vector representing the point to compute the distance from
  • integer childIndex: The index of the collision shape attached to this item we want the bounding box of
  • Libraries.Compute.Vector2: The direction of the point from the shape

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.

Parameters

  • number containsX
  • number containsY

Return

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

Example

use Libraries.Interface.Item2D

Item2D item
item:SetPosition(50, 50)
item:SetWidth(100)
item:SetHeight(50)
boolean value = item:Contains(125, 70)

Copy()

Return

Libraries.Interface.Views.ControlView

CreateNodes(Libraries.Game.Collision.BroadphaseCollision2D broadphase, Libraries.Game.Collision.PhysicsPosition2D transform)

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.

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

use Libraries.Interface.Item2D

Item2D parentItem
Item2D child1
Item2D child2
Item2D grandchild
parentItem:Add(child1)
parentItem:Add(child2)
child1:Add(grandChild)
parentItem:Empty()

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.

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.

Parameters

  • boolean flag: Whether or not to enable physics for this item

Example

use Libraries.Game.Graphics.Drawable

Drawable circle
circle:LoadFilledCircle(30)
circle:EnablePhysics(true)

EndMouseOver()

Equals(Libraries.Language.Object object)

This action determines if two objects are equal based on their hash code values.

Parameters

Return

boolean: True if the hash codes are equal and false if they are not equal.

Example

use Libraries.Language.Object
use Libraries.Language.Types.Text
Object o
Text t
boolean result = o:Equals(t)

FastMoving(boolean flag)

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

Parameters

Example

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)

Vector2 currentVelocity = item:GetLinearVelocity()
