Aw im sorry to see this die, its nice that you're releasing the source though ^^

Alright, attached is the physics engine.  You should call sub(UP) to update the engine.  sub(IP) to initialize.  sub(AO,X,Y,Width,Height) to add an object.  Remember X and Y are *64.  Your program should have a label, OC (Object Callback) that the Update loop calls to do things like drawing.  The current object is returned in I.  For example, your object callback could look like this:
Lbl OC
Pt-On({I*18+L1}^r,{I*18+L1+2}^r,Pic1

I have to leave, but I'll document more later.

You should also pass a tilemap into UP, 7x7 tiles.  Anything not 0 is considered solid and factors into collision detection.  sub(DM,Map) will draw the map.

Speaking of Blinded by the Dark, that game's source is available. Maybe we could make an axiom for it! it was a pretty nice engine, even if the greyscale health wasn't exactly the best (on mine at least)

If you mean the shadows, that would actually be cool. I think Michael_Lee would like this, although I think he got a much faster speed on his new versions of Light.

@DJ

Comparing BBtD to the most recent screenies of Light is like comparing the 84+ version of block dude to the nspire's.


A note: BBtD doesn't check to infinite distance, and appears to do it with a line function (notice the noise at the ends, which IMO adds realism anyways) as compared to light, which goes to infinite distance which takes even more than you'd think, since it has to detect how far away from the screen it is as well as where you can see, and has to check much more of the area.

Maybe an axiom that supports scanning infinite, or different set distances? that would be really cool. Plus, the Half life engine. Both combined could do a really sweet vision-based sidescroller.

Yeah, probably. It would be a nice idea to check out, at least.

I just thought I'd mention that after Motherload, I'm picking this back up from scratch.  It shall be glorious.

Wow glad to hear! Will the graphics be similar or will they have textures and such stuff?

Personally I don't mind a framerate loss, because at high framerate it's hard to see stuff moving anyway, especially on the Nspire LCD.
