Libraries.Interface.Controls.Scenes.Items.EditorItem Documentation

The Editor Item class represents an object in the Scene Editor that is in the scene and is being added, removed, or having its properties modified. The main purpose of this class is to get and set information about certain properties of an item in the scene such as those for physics calculations like mass and restitution. Properties relating to physics and others important to the scene like position and the texture of the object will be saved to the scene file.

Inherits from: Libraries.Interface.Item, Libraries.Language.Object

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)

CancelBehaviors()

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

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)

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.

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.Item

Item parentItem
Item child1
Item child2
Item 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.

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

Text t
boolean result = o:Equals(t)

FinishCollision(Libraries.Interface.Item item)

This action is used to indicate that two items that were previously colliding no longer are. The FinishCollision action should be called on both Items involved, with the other item passed as a parameter to the action.

Parameters

Example

use Libraries.Interface.Item

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

Focus()

This action sets focus on this Item. If the Item is not focusable, it will instead look through the parent hierarchy and set focus on the first focusable ancestor. If no focusable Item can be found, this action will have no effect.

ResetScale()

ResetScale sets the scale of the object along each axis to the default which is usually 1. The scale of the object affects how large it is in the scene. So a scale of 2 on the x-axis means the object is twice as big on the x-axis than when normally sized.

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

  • boolean accepts: True to set this Item to receive mouse events, or false to ignore them.

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

  • integer newAccessibilityCode: the new accessibility code for this Item.

SetAccessibilityRoleDescription(text newRoleDescription)

This action sets a custom accessibility role description for this item. This should only be done if there is not a standard accessibility code for the type of item being implemented. If the item behaves very similarly to a standard control type, then set the accessibility code to that standard type while also setting the role description. For example, if implementing an item that extends Control, is keyboard focusable, and responds to activation via both mouse clicks and the Space key, like a button, but it shouldn't be described as a button, then set the accessibility code to BUTTON and the custom role description to whatever is appropriate. If there isn't a suitable accessibility code, or if in doubt, set the accessibility code to CUSTOM.

Parameters

  • text newRoleDescription: the new custom role description for this Item.

SetDescription(text newDescription)

This action sets the internal description of the Item.

Parameters

  • text newDescription

SetEditorPhysicsEnabled(boolean enable)

This action sets whether or not this object will part of physics calculations that happen as the game runs. If phyics is not enabled then certain properties of the item will cause an error if the user attempts to view or change them. If physics is enabled than the object can be affected by force, and velocity calculations as the game runs.

Parameters

  • boolean enable: If true the physics enabled property will be set to true, false otherwise

SetEditorResponsiveness(integer responsive)

This action sets how physics (linear velocity, angular velocity, force, torque) will affect the object. There are three possible values to be set: 0 indicates that the object is UNMOVABLE, which means no matter what forces or torques is applied to the object, the object will not move. 1 indicates that the object is NON_RESPONSIVE, which means that only setting the angular velocity and linear velocity of this object will affect how the object behaves. 2 indicates that the object is REPONSIVE, which means that this object will behave differently when you apply forces and torques to this object.

Parameters

  • integer responsive: Integer representing how physics will affect the object.

SetEditorRestitution(number restitution)

This action sets how much energy that this object will loose after a collision. If you want the object to not loose any energy, then you can pass in 1.0. If you want the object to loose a lot of energy (meaning, they would probably move a lot slower after the collision), then you can pass in a 0.0. You can also use the values between 0 and 1.

Parameters

  • number restitution: The coefficient of restitution.

SetFocusable(boolean focus)

The SetFocusable action sets whether or not this Item should be focusable. If the Item is currently focused and made unfocusable, then it will lose focus, and there will be no focused element.
