Description

Adding a SortingGroup component to a GameObject will ensure that all Renderers within the GameObject's descendants will be sorted and rendered together.

A common use case for having a SortingGroup is to create complex 2D characters that are made up of multiple SpriteRenderers. When several clones of such a character overlap, their individual body parts might not be sorted properly resulting in a visual glitch where the the body parts interleave. For example, the hands of two characters might be sorted in front of their bodies, where you would expect one entire character to be drawn in front of the other character. The SortingGroup component solves this by ensuring the entire branch of the character are sorted and rendered together.

The descendants of the SortingGroup are sorted using the same SortingLayer and Renderer.sortingOrder. However, they are only sorted against other descendants of the SortingGroup and not with any renderers outside of it. This allows you to reuse the same SortingLayers (for example, "Hands", "Torso"...) to sort body parts while ensuring they never interleave with other clones of the character.

The SortingGroups, together with other renderers, are sorted using the SortingLayer and Renderer.sortingOrder. Additionally, they can be nested within other SortingGroups. This is useful if you have branches of descendants that should not be mixed up i.e. the "Left Hand" vs the "Right Hand" hierarchy branches.

Public Methods

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagIs this game object tagged with tag ?
GetComponentReturns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildrenReturns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParentReturns the component of Type type in the GameObject or any of its parents.
GetComponentsReturns all components of Type type in the GameObject.
GetComponentsInChildrenReturns all components of Type type in the GameObject or any of its children.
GetComponentsInParentReturns all components of Type type in the GameObject or any of its parents.
SendMessageCalls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwardsCalls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the GameObject.

Static Methods

DestroyRemoves a gameobject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active loaded objects of Type type.
InstantiateClones the object original and returns the clone.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
