Need Help. Check Position before collision with playfield.

[Erik Zimmermann]

I will make a little car racing game. would like to check position before the car collides with the playfield. Whats the best way to do this? 
I don't calculate the coordinates for pfread. My car is 8x8 pixel and playfield had 32 lines.

 

How can help me?

* Use pfread

 

or

 

* Put a missile or ball just ahead of the player at the tip that's moving forward.  Check the collision of that instead of the player sprite.  Note that the missiles and ball are always going to be smaller than the player sprite so it's not complete collision detection that way.

i will use pfread.  In the future, i will make a enemy AI.

the car moves independently on the map.
It doesn't touch walls. It finds free space to move. Maybe it haunts me too.
