Knuckles sliding and falling animations won't load

Edit: Guys! the ram adress suggested don't work! i still need someone to help me solve this!


Well here i am with another puzzle that i can't sought.(although it maybe more simple than i think) when knuckles falls from glide or slide, he doesn't use the animtion i set for him. Instead he stills uses the glide animation, no matter what animation i change it too. Here is the whole gliding code:

Code:

If you can help me it would be great thanks! really i mean i'm stumped with this.

 

"byte_315CC2 :".....


This changes the animations of Knuckles Gliding ... maybe this can help you.

 

Not to be rude Tornado but don't you think i already know that?! i mean copying the code over and unserstanding it and all =P. So no thats nothing to do woth the sliding or falling code.

 

$1A is the frame number in the mapping file. So open sonmaped and load art and shit and check for the frame number and change in the code to the frame number you want. Also, there is a part for loading the dust, did you remove it?

 

Again hanoc this doesn't help. I know what frames are, and i have done the right frames and the animations are set, but no matter what frame or animation i change it to it always loads the gliding animation. In order for me to explain a bit more so people understand is that i think its something to do with the code. But obviously i don't what, because i checked with Hitaxes and his is practically the same.

 

Did you Rip it from Sonic 2 & Knuckles UpMem Disassembly? And are you porting it to Sonic 1 or 2?

 

This is from sonic2k.asm, and its for sonic 1.

 

I'm not that familar with Sonic 1 but, but I do know that RAM addresses are different between it and Sonic 2. And based on your code, you are still using the adresses referenced in S2K. I would say it may be a RAM address used in Sonic 1 that your Knuckles code is using.


EDIT: $FFFFF7AC is already being used by Sonic 1. It has something to with loops. You need to change that and probably the other addresses to something that is unused in Sonic 1. I think $FFB0 is available. I would search here and retro for unused RAM addresses. I know there is a thread for it. Good Luck.

 

Well i was told this is not specifically for sonic 2 or 2k. In other words i could port this sonic 1 and it work. But i guess i will try your way, although i did try address before and it still didn't work. But perhaps the address i used are alread used. I don't know this is really enoying.

 

Please help! it still won't work!

 

To be honest its pretty tricky figuring out if its a ram address issue or if its related to your actual code without your ASM file - I understand that you wont want to put it up here becasue of size or because of prying eyes so I would say make a list of all used ram and then cross referance your knuckles code with the list to make sure. Hope you figure it.

 

Well guys I think knuckles will be removed from my hack, seems I can't figure out the problem and no one who have replied knows what is worng. Its not a ram adress I'm sure, But I do know its something to do with the ani file. I took the one from s2k, to test and his falling worked but still not his sliding. And then I put it back to my code and it doesn't work again. So you might aswell trash this.....
