Struct LocalToWorldSystem

This system computes a LocalToWorld matrix for each entity

Implements

ISystem

Namespace: Unity.Transforms

Assembly: Unity.Transforms.dll

Syntax

[BurstCompile]
[WorldSystemFilter(WorldSystemFilterFlags.Default|WorldSystemFilterFlags.Editor, WorldSystemFilterFlags.Default)]
[UpdateInGroup(typeof(TransformSystemGroup))]
[UpdateAfter(typeof(ParentSystem))]
public struct LocalToWorldSystem : ISystem

Remarks

Entity transformation hierarchies are created using the Parent and LocalTransform components, and maintained by the ParentSystem.

For root-level / world-space entities with no Parent, the LocalToWorld can be computed directly from the entity's LocalTransform.

For child entities, each unique hierarchy is traversed recursively, computing each child's LocalToWorld by composing its LocalTransform with its parent's world-space transform.
