Re: Sprites
Thanks Dbug, I am doing part of that already it seems. I am keeping the old coordinates of the sprites and then I paint repaint those rectangles using the back buffer. The speed is a bit better now that I am not dumping all the background. I will now try to improve my paint_sprite routine, I know th...

Can you elaborate a bit more how this "blit rectangles" technique would work, please?

Re: Sprites
I must try just to copy the section of the background that will be painted on(a bit bigger actually).

Re: Sprites
I only paint the background once in a buffer then I copy it each time to the other buffer to paint the sprites. Thank you for the hints on checking the timing. I did saw that on oricutron, one can use F9 to reset cycles, I will check the docs to see how to use this feature. At first I thought of hav...

Re: Sprites
Finally I had some time to work a bit more in this project... I have now my buffers and 4 sprites (masked) working but all moves so slowly. It must be because I am using the following approach: - Play area : 24x160 - buffer for the background 24x160 - second buffer where I paint the sprites 28x176 I...

Re: Sprites
At the moment my routine is not optimised, I just wanted to see if things were working. So I am adding 40 at every line to the low byte of the zp pointer and then add one to the high byte if carry is set but I knew this could done in another away, absolute addressing as you said. Thank you for the h...

Sprites
Hi What would be the most efficient way to way to plot 4 sprites (3x16 bytes)? The sprites actually are 2x16 bytes but I will have them preshifted in memory so when painting the sprites I will paint one more byte for each of the 16 rows. I will be using masks because the background must be preserved...
