@ztrumpet: That's a problem though, since sinx / cosx and cosx / sinx actually comes out to either 0 or 1. So you actually have to inflate the first term by 128 (or some other factor) and then don't forget about the signed division :P Additionally, my problem was that not only did I have to scale by 128, I had to scale by 128 or -128 depending on which direction you were facing

@ztrumpet/DJ. I guess that would be good

@willrandship: How do you mean? Is there a scaling command?

I think so.....hang on.

Hmm, guess not. I'd thought someone had mentioned scaling in an old thread.

Oh XD it was a thread about asm, not axe. :P sorry.

Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

Spoiler For Pokemon TI:
Axe port of Pokemon Red/Blue to the 83+/84+ family. On hold.

Spoiler For Nostalgia:
My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

Spoiler For Finale's Super Insane Tunnel Pack of Doom:
I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

Yeah, that might have been part of what confused me :P but that one only talks about enlarging sprites, not shrinking them.

Hm, looks interesting. I think I'll go with making the user draw all the different zoom levels though, or possibly have the auto scale be an option

Ah, I see.  That's quite difficult.  Nice job on that. ;D

Scaling really has to be pre-rendered. Rendering a sprite takes 0.1 second, meaning if there are 10 sprites on the screen, your game run a bit under 1 FPS.

I take it you mean scaling a sprite takes .1 seconds? That's really horrible for realtime rendering, but I suppose you could prescale them as it starts if you're super desperate for space.

Yeah 0.1 second, as shown in my screenshot in the linked topic. This is why they need to be pre-rendered. When entering a room with new sprites they should probably be pre-rendered there.
