Sonic Engine help

I can't help you building a Sonic engine (I dunno how to do it), but I searched for the same thing as you (open source Sonic-like engine) some months ago, only to fail miserably. You're better off writing it yourself.
Starting points, you'd want? The collision arrays of Sonic 1 and 2, will get a good idea in your head when it comes to collision.

It's nice that you're trying to do a Sonic game for the Dreamcast. I'm actually trying to port Sonic 1 to the PSX.

 

Maybe this can help?

 

Here is a good Sonic engine for Game Maker, made by Dekoldrick.

 

Ugh. You don't want "help", you want someone to do it for you. I got both of your PMs, and that's exactly why I never responded to either of them. Your first was in May, for god's sake, and you haven't got ANYWHERE?

Listen, it's not hard to follow the code in the current disassemblies, and there have been several threads on this forum touching on how different parts of it work. If you need something straightforward, there do exist other alternatives, such as the highly commented Project Mettrix scripts I built for E02, based heavily on the functionality of the original games. Also, I haven't personally had a look at any of these "opensource" TGF/GM/etc engines, but there are many, and regardless of the level of commentation in each one, they at least provide a different perspective on the same methods, and to someone who wasn't just looking to grab some pre-made code that they could slap directly onto their target system, could possibly be helpful in determining just exactly what is going on

Also, for future reference, I'm not tempted by promises of "ports". I'll do my own, thanks, and I'm pretty sick of people thinking it's an easy way to grab at my code, because you're far from the first to try. If all you're interested in is strictly a port of my software to a different system that I don't personally have the resources for, then I would appreciate very much if you provided or helped to provide me with those resources. Otherwise, no thanks.

 

Wouldn't porting the code straight from a disassembly be sorta kind of copy and paste too? I mean, with your criteria, to do things properly he should figure out how to do the entire engine himself without looking at anything already made at all >_>

 

I wouldn't look at a disassembly. It taints my code if I even wanted to use it for something else than a sonic fangame.
Also, it isn't very hard to figure how something is done, I had no idea how to make a tetris game and yet I made one by seeing how stuff acted.

 

Programming a Tetris engine doesn't require you knowing trigonometry, you know...

 

Didn't reply to this because I thought no one else was going to, but now people are I've remembered what I was going to say.

Your wanting people to do the main core of the engine for you? Sure, having a storyline and artwork is fine but if you let other people do the work you're not going to go ANYWHERE.

EDIT: I just realized who this is, I haven't spoke to you for ages :P

I think reading the disassembly and going from there will be the best idea.

 

Disassemblies are in the big sticky right above here....

I know what I was asked, and this thread was pretty suspect. Maybe you didn't know what you were asking for?
Anyway, this is all more than most of the rest of us had to go by, so you should be able to get something decent out of it. Don't forget to credit the authors of your resource materials
