Subject: AOTM AFOS problems From: "Shrek" <matzieq@xxxxxxxxxxxxxx> Date: Thu, 1 Jul 2004 01:57:30 +0200 |
Hello there!
I'm working on the AOTM AFOS now, I
decided to rewrite the game almost from the beginning. Now I'm playing with the
vertical positioning routine mentioned by Andrew Davie in his tutorial,
something like this:
SEC
TXA SBC Ufo_Y ADC #12 BCC EndOfDrawingUfo CLC ADC Ufo_Frame_Offset TAY
LDA (Ufo_Sprite_Ad),Y STA Ufo_Buffer EndOfDrawingUfo
It was supposed to be around 20 cycles. I've
inserted three such routines into one scanline, and 20*3 is 60 as far as I know.
But when I run it, it seems, that it doesn't fit into the line! So what's
wrong?!?
I attach the code, and the place where all
trouble began is commented "HERE BEGINS THE PROBLEM".
Please, help!... I don't know what to do... I
begin to feel frustrated!
