Question How to parent an entity while maintaining world position

I am trying to parent an entity in ISystem as follows:

Code (CSharp):

1. ecb.AddComponent(selectedAspect.Entity, new Parent { Value = parentEntity });

This results in the child entity getting teleported to a new world position, which I assume to be due to the non-changing local position. Therefore, I tried to modify the local position using the following:

Code (CSharp):

1. transformAspect.TransformPointWorldToLocal(transformAspect.WorldPosition)

Which, however, is always returning float3(0,0,0)

 

Not tested, but try somphing like this:

Code (CSharp):

1.  
2. var local = parentTransformAspect.TransformPointWorldToLocal(childTransformAspect.WorldPosition);
3. ecb.AddComponent(childEntity, new Parent { Value = parentEntity });
4. ecb.SetComponent(childEntity, new LocalTransform { Position = local /** scale and rotation **/ });
5.  

 

Thanks, that solved it.
