I have 2 structures which follow:
struct
{
  int min_x;
  int max_x;
  int min_y;
  int max_y;
}TILES[30][40];

and

struct
{
  int min_x;
  int max_x;
  int min_y;
  int max_y;
}CARBOX;

I am in screen mode 640x480 using the allegro library..
all my tiles are 16x16, and I store the coords of all of them in the first
struct.

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
