Movement Issues

[GWGord]

I've got a bit of a bizarre problem going on. I'd posted a few days ago about problems I've been having moving tiles around on a grid. I've got that mostly solved now, but the issue of getting them to STOP moving is puzzling me to no end.

Here's the situation: Every second or so, the tiles move one space. The direction is determined by the direction they're facing. They're supposed to stop when they reach the limits of the board, which I have defined by an array object.
ONE of the tiles will stop when it's supposed to, without any problem. Any other tiles on the grid will pass through without any trouble though.

There's no collision detection in place - what I'm doing instead is marking occupied spaces as 'occupied', and the tiles are not supposed to attempt to enter a tile marked that way. The game board is surrounded by wall pieces that automatically mark their spaces as occupied.

Anyone have any thoughts?

It sounds like you're running into an object selection problem, in that you're using conditions that somehow select just one instance of your tile objects (the last one placed on the frame editor). Getting around this usually means setting up a fastloop to check each individual object in turn, though it's possible there's a simpler solution as well - perhaps post an example of the problem in the File Archive section of the forum.
