Question Transform.Rotation to Entity.LocalTransform.Rotation

A dummy question which I clearly can't get right: how one should transfer GameObject's beautiful Transform.Rotation to Entity.LocalTransform.Rotation in code?

I tried:

Code (CSharp):

1.  
2. new LocalTransform
3. {
4.    Position = prefab.placementInfo.position,
5.    Rotation = quaternion.Euler(
6.             math.radians(prefab.placementInfo.rotation.x),
7.             math.radians(prefab.placementInfo.rotation.y),
8.             math.radians(prefab.placementInfo.position.z),
9.             math.RotationOrder.XYZ), // tried different RotationOrder. and it did not work
10.    Scale = prefab.placementInfo.scale
11. }

Could anyone please help?

 

Transform.Rotation is quaternion. LocalTransform.Rotation is also quaternion. So, given that there is implicit conversion from UnityEngine.Quaternion to Unity.Mathematics.quaternion the answer is simple assignment:

Code (CSharp):

1.  
2. new LocalTransform
3. {
4.     Position = prefab.placementInfo.position,
5.     Rotation = prefab.placementInfo.rotation,
6.     Scale = prefab.placementInfo.localScale.x,
7. }
8.  

But I belive that you have something other than UnityEngine.Transform, because there is no 'scale' field in it.

 

ah, yes, but PlacementInfo is a custom structure and Rotation field is actually a Vector3 with 3 angles.

 

Default rotation order when converting form eulers to quaternion is ZXY. So here is conversion:

var rot = quaternion.EulerZXY(math.radians(prefab.placementInfo.rotation.xyz));

But if you need to transfer rotation from UnityEngine.Transform you should not do this double conversion (quaternion->euler->quaternion)
