Back centre point of Game Object with rotation

Hey all,

I would like to ask you how to properly get back centre point of GameObject with rotation.

Code below works fine until I change rotation of parent GameObject, see screenshot below:

Code (CSharp):

1.             Vector3 spawnAreaSize = spawnArea.GetComponent<Renderer>().bounds.size;
2.             float lengthSP = (spawnAreaSize.x) / 2; //Do not spawn unit on the edge of spawn-area (-unitSize.x)
3.             float x = -lengthSP + spawnAreaPosition.x;
4.  

 

Use TransformPoint: https://docs.unity3d.com/ScriptReference/Transform.TransformPoint.html
