World vs Local Position Helper

Created as part of a Tutorial series on my channel:

Designed to show the difference between local and world space in Unity. The Parent object (P) and Child (C) can be moved around, the child can move using local (or relative) position, or world.

To use the tool, position the mouse somewhere on the grid and press:

- Left Mouse or 1 key: Move the parent to the chosen grid vector.

- Right Mouse or 2 key: Move the child to the chosen grid vector, as a position relative to the parent (local position).

- Middle Mouse or 3 key: Move the child to the chosen grid vector, as a position relative to the world (world position).
