Hello community.

I have this wierd problem with flash that I can’t understand. I am in the middle of making a tile based engine, and I have decided to do boundaries by hit testing a MC in the tile in question. Well if you will donwload my file and take a look…

[http://www.uploads.sc/download.php?file=b8bb98f8832eb9be7ff240e976b7165f](http://www.uploads.sc/download.php?file=b8bb98f8832eb9be7ff240e976b7165f)

You will find that in line 34 it states thus:

if (!gameMC.tiles.tile\_3\_4.hitTest(gameMC.you.\_x+newx, gameMC.you.\_y+newy, true)) {  
gameMC.you.\_x += newx;  
gameMC.you.\_y += newy;  
}

And that is great and all seeing how tile\_3\_4 is the grayed out block if you test the program. But when I walk over to tile\_3\_4 it does not stop me while on the other hand tile\_0\_0 (top left) does the appropriate behavior that 3\_4 if supposed to do. Please someone help me figure this out.

PS, I don’t know how long it will be till I get back to this but under 24 hours.
