Re: A83: ASM Routines (C8:*




I actually have tried to learn similar things, here is what I gather.

What do you mean by text scrolling?  The best thing to do would be to 
store your text in sprites, and then display slighly past the end of the 
screen.  That is the fastest way I have  thought of for scrolling.

This is fun too, I think the best one for this is to use a pixel test to 
find out if you are hitting a wall, then use the ball's  coordinates to 
find out what type of wall it is, then it is just algebra.
