Accessors

children

get children(): GameObject[]
Get only first-level children of this GameObject.

Returns GameObject[]
- Defined in Core/GameObject.ts:70

parent

get parent(): null | GameObject
Get the parent of this GameObject or null if it's root or not already attached to a tree.

Returns null | GameObject
- Defined in Core/GameObject.ts:46
set parent(value: null | GameObject): void
Protected
Set the parent of this GameObject. This should only be used internally by the engine.
Parameters
- value: null | GameObject
Returns void
- Defined in Core/GameObject.ts:55

root

get root(): null | RootGameObject
Get the root of the tree this GameObject is attached to.

Returns null | RootGameObject
- Defined in Core/GameObject.ts:77

Methods

addBehavior

Returns Behavior[]
- Defined in Core/GameObject.ts:198

getAllChildren

getAllChildren(): GameObject[]
Returns all children of this GameObject, including children of children, and so on. All the hierarchy. Does not include the GameObject itself.

Returns GameObject[]
- Defined in Core/GameObject.ts:116

getBehaviors

getBehaviors<T extends Behavior>(BehaviorClass: new (...args: any[]) => T): T[]

Returns T[]
- Defined in Core/GameObject.ts:189

getFirstBehavior

getFirstBehavior<T extends Behavior>(
BehaviorClass: new (...args: any[]) => T,
): null | T
Get the first behavior of a specific type attached to this GameObject or null if none is found.
Type Parameters
- T extends Behavior
Parameters
- BehaviorClass: new (...args: any[]) => T
Returns null | T
- Defined in Core/GameObject.ts:178
