Collision Detection

Dennis Debro Asked

Also how do you check for collisions? Do you use the same methods used with the 2600?

Eric Ball Answered

Yep, the same methods. Ohh, you mean the TIA collision registers :-) MARIA doesn't have any collision registers, so your game has to track sprite positions and handle and collisions manually. (The sprite list concept used by the 7800 doesn't lend itself to simple collision flags anyway.)

Shrek Asked

I have one more question, if I can: how does MARIA handle collision detection? Do I have to do this in software way?

Eckhard Stolberg Answered

Since there are no real freely moving objects, there is no hardware collision detection in the 7800. You have to keep track of the positions of your objects yourself and see if any of them collide.
