imitate a pattern

Make a pattern in a room. Ask the game player to push some objects to imitate this pattern. Doing this will destroy a wall and enable the player to progress to the next room.

A couple of students in the Murdoch Uni Game Making competition asked me for assistance with this problem.

I have written a demo about how to do this.

I have blogged about how I screamed at my computer due to poor understanding / documentation about how the position_meeting() function works in Game Maker.
