I store all the coords at any point in time for the car's x & y values in the 2nd one.. I want to be able to cheq if the car can move or not.. and the car moves 6 pixels at a time in any direction. Also the car can only not move if the tile is of type 1 which is figured out from another structure.. which means its solid.. I just need some example code how to tell if the car can move or not. pleeze help me.. Ken.. email me at: storm3 AT geocities DOT com
