3x3 Sliding Puzzle

This prefab really shows the capabilities of mapping on the Source engine. The puzzle randomly shuffles itself 50 steps (without bouncing the same piece) on map spawn. Once the puzzle is completed, the missing piece is shown.

After editing the puzzle in large scale, it was made into a prefab and created in the desired location using the Block Tool in bounds of 11x32x32 with Texture Scale Lock enabled. The reset relay was then hooked up to a button. The puzzle was also hooked up to a timer and a move counter. The custom materials used are bspzipped into the map.

Note:Compiling the shrunken puzzle will give you microbrush warnings. These are only warnings and do not have any effects on the compilation of the map.
