Subject: [stella] Star Fire: Radar completed! Magical Mystery Bug Found! From: Manuel Polik <cybergoth@xxxxxxxx> Date: Tue, 22 Oct 2002 11:16:35 +0200 |
Hi there! I found the bug! It's still magical mystery to me: Instead of LDA sprtsizetype,X AND #%00000110 ORA #%00010000 STA sprtsizetype,X I did LDA sprtsizetype,X AND #00000110 ORA #00010000 STA sprtsizetype,X While this clearly was the bug - - I don't have the slightest clue what it's got to do with wether using RESBL or RESM0 - I don't have the slightest clue how this _ever_ worked at all with the old code As long until I changed RESBL to RESM0, it perfectly did AND #%00000110 ORA #%00010000 even though I had AND #00000110 ORA #00010000 written in the code... Beyond me, I'm sorry. But maybe it'll be a future hint for others searching similar magical mystery bugs... Hope you enjoy the look'n'feel of the radar, I consider my work done for that part. Turned out nice I think. Note: The mothership is not detected by radar, this is intentional - it has a super secret stealth mode :-) There's not enough cycles left to do something really fancy on the side of the radar, but I've 18 scannlines left, where I can possibly display the shield state any way I want. Any ideas? Doing the old "shield bar" once more, or something different this time? :-) As for displaying the score, I decided to display it on an extra screen between levels, like Christopher suggested. I think I'll switch back in the other 4K bank for that, missusing Thomas 6char routine :-) Greetings, Manuel
