Add(integer index, Libraries.Interface.Item2D item)
This action will add an Item2D to this Layer's array of items at the index location. It will be updated along with the rest of the layer, and will be drawn on the screen (if it is visible and possible to draw the given Item2D).
Parameters
- integer index: The index to store the item at in the layer's array of items.
- Libraries.Interface.Item2D: The Item2D to be added to this layer.
Example
use Libraries.Game.Game
use Libraries.Game.Layer2D
use Libraries.Interface.Item2D
use Libraries.Game.Graphics.Drawable
class Main is Game
action Main
StartGame()
end
action CreateGame
// Item2D objects aren't visible, but can still be used for game logic.
Item2D area
area:SetSize(50, 50)
area:SetPosition(100, 100)
// Drawables inherit from Item2D, so they can be added too.
Drawable circle
circle:LoadFilledCircle(25)
circle:SetPosition(300, 100)
Layer2D layer
layer:Add(0, area)
layer:Add(1, circle)
AddLayer(layer)
end
action Update(number seconds)
end
end
Add(Libraries.Interface.Item2D item)
This action will add an Item2D to this Layer. It will be updated along with the rest of the layer, and will be drawn on the screen (if it is visible and possible to draw the given Item2D). The Item2D will be added to the back of the layer's internal array of items.
Parameters
- Libraries.Interface.Item2D: The Item2D to be added to the layer.
Example
use Libraries.Game.Game
use Libraries.Game.Layer2D
use Libraries.Interface.Item2D
use Libraries.Game.Graphics.Drawable
class Main is Game
action Main
StartGame()
end
action CreateGame
// Item2D objects aren't visible, but can still be used for game logic.
Item2D area
area:SetSize(50, 50)

end
action Update(number seconds)
end
end
AddCollisionListener(Libraries.Interface.Events.CollisionListener2D listener)
AddCollisionListener will add a collision listener to this layer. The collision listener will be notified of collisions occuring on this layer, and is responsible for managing the collision events.
Parameters
AddGestureListener(Libraries.Interface.Events.GestureListener listener)
This action will add a GestureListener to the layer. When the layer receives a gesture event, it will first try to find the topmost item which can handle the event. If the event is not handled, then all GestureListeners in the layer will receive the event.
Parameters
- Libraries.Interface.Events.GestureListener: The GestureListener to add to this layer.
Example
use Libraries.Game.Game
use Libraries.Game.Layer2D
use Libraries.Interface.Events.GestureListener
class Main is Game
// For most programs, this should be replaced with
// a custom class inheriting from GestureListener.
GestureListener myListener
action Main
StartGame()
end
action CreateGame
Layer2D layer
layer:AddGestureListener(myListener)
AddLayer(layer)
end
action Update(number seconds)
end
end
AddJoint(Libraries.Game.Physics.Joints.Joint2D joint)
This action will remove an Item2D from the front of the array of items in this layer, and return the item that was removed. This is functionally the same as calling "RemoveAt(0)".
Parameters

use Libraries.Interface.Item2D
use Libraries.Game.Graphics.Drawable
class Main is Game

end
action Update(number seconds)
end
end
AddMouseListener(Libraries.Interface.Events.MouseListener listener)
This action will add a MouseListener to the layer. When the layer receives a mouse event, it will first try to find the topmost item which can handle the event. If the event is not handled, then all MouseListeners in the layer will receive the event.
Parameters

AddLayer(layer)
end
action Update(number seconds)
end
end
AddMouseMovementListener(Libraries.Interface.Events.MouseMovementListener listener)
This action will add a MouseMovementListener to the layer. When the layer receives a mouse event, it will first try to find the topmost item which can handle the event. If the event is not handled, then all MouseMovementListeners in the layer will receive the event.
Parameters
- Libraries.Interface.Events.MouseMovementListener: The MouseMovementListener to add to this layer.
Example
use Libraries.Game.Game
use Libraries.Game.Layer2D
use Libraries.Interface.Events.MouseMovementListener

AddToFront(Libraries.Interface.Item2D item)
This action will add an Item2D to this layer's array of items at index 0. It will be updated along with the rest of the layer, and will be drawn on the screen (if it is visible and possible to draw the given Item2D). Adding an item to the front will cause it to be drawn and updated before other items in the layer, and other drawn items will appear to be on top of it.
Parameters

end
AutomaticallyClearForces()
This action will add a TouchListener to the layer. When the layer receives a touch event, it will first try to find the topmost item which can handle the event. If the event is not handled, then all TouchListeners in the layer will receive the event.

use Libraries.Interface.Events.TouchListener
class Main is Game
// For most programs, this should be replaced with
// a custom class inheriting from TouchListener.

end
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
- Libraries.Language.Object: The object to compare to.
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)
Draw()
This action will draw all items in this Layer on the screen (if they can be drawn and they aren't hidden). If the Layer is currently hidden, then this action will do nothing. This is automatically called by the Game class as needed. Most users will never need to use this action directly.
Empty()
This action will clear all the items in this layer.
Example
use Libraries.Game.Game
use Libraries.Game.Layer2D
use Libraries.Game.Graphics.Drawable
class Main is Game
action Main
StartGame()
