Brick Centering

A script that automatically aligns a player's temp brick to the center & top of contacted bricks when it is first placed.
Use /centerbricks or /cbs to toggle it on and off.

Example:
- Plant a 32x32 cube.
- Type /cbs.
- Get a 32x32 plate from the brick menu.
- Fire with the brick gun anywhere at the cube.
- Brick appears on top of the cube, perfectly aligned.
