setting CompositeScale component gives error because no scale component exists
Best Answer
using Unity.Mathematics; using Unity.Transforms;
float3 newScale = new float3{ x=3f , y=3f , z=3f };
if( entityManager.HasComponent<LocalToWorld>(entity) )
{
var ltw = entityManager.GetComponentData<LocalToWorld>(entity);
entityManager.SetComponentData<LocalToWorld>( entity , new LocalToWorld{
Value = float4x4.TRS(
translation: ltw.Position ,
rotation: ltw.Rotation ,
scale: newScale
)
} );
}
else Debug.Log($"{entity} has no {nameof(LocalToWorld)} component");
Unity.Transforms.LocalToWorld is more or less UnityEngine.Transform equivalent. Scale can be local (scalar) scale or world scale depending whenever entity has Parent or not (the same is true for Translation ie local position ).
