💬 One of the comments I get a lot is people asking why the code shown in the video isn't working, and usually the reason is because in the video I showcase some system working in 2D and they're trying to get it to work in 3D.
It's pretty simple to get the mouse position in 3D but it is a completely different method compared to 2D.
So here let's see how both methods work and why they need to be different.
2D: Camera.main.ScreenToWorldPoint(Input.mousePosition);
3D: Physics.Raycast(Camera.main.ScreenToRay(Input.mousePosition, out RaycastHit raycastHit));
