Ok, I'm working with papersnowman on a new project now, donkey kong. It will be a tilemapped side-scroller. I have written the scrolling engine so far. It masks the tilemapped foreground on top of a rotating background. I will later release the engine so it can be used by anyone.

PS: Pardon the choppyness of the SS, calccapture is just hateful like that

EDIT: I've timed the engine to about 500,000 CC's per frame, giving it a framerate of about 12. This isn't too bad, but I'll definitely come back to it, making optimizations wherever I can.

donkey kong arcade, donkey kong gb, donkey kong country, which one? (there are lots)

Sorry, my bad. The Donkey Kong Country (SNES) level-set, but the B&W look of Donkey Kong Land (GB)

I remember playing that on my GameBoy. Sounds awesome and the scrolling is nice

. Are you drawing the sprites?

Sounds good. Glad to see you back!

Ok, I got a bit of an update, but it's not much. I converted to an app, because I don't believe in forcing someone to run 10k programs 0.0 . Also, I have made a few platform tiles, including slopes. I also have a better rendition of the rotating background thing I talked about earlier. It is a bit choppier now, because I had to use PTI instead of VTI, since this is an app, but you can still see what's goin' on. Hope you guys like it!

Special thanks to DWEdit, since I'm using his bubble splash screen.

It looks great! The text becomes blurred, but I guess it's the tiles that matter.

Well, it is an animated screen shot from an emu.

This may or may not help, but in PTI, if you open up the debugger interface, you'll see in the bottom left an area that says LCD Physics. Tweaking the percentages might help reduce the blur, but unfortunately, the rate that PTI takes frame for .gifs is fixed iirc.

Nice screenshots!

This looks like it will end up being really awesome.

To Liazon: i didn't use pti's screen capture, pti takes really small pics. This is calccapture screening pti.

Update: I've made some optimizations, and cut the routine down to 450,000 CC's giving it a framerate of about 13 fps. The speed increase is a bit noticable in this pic.

Wow, very nice. I hope to be entertained for hours with this ^_^ The screenshots are looking nice, too.

What is your routine to measure FPS.

bfr · « **Reply #13 on:** April 24, 2007, 10:36:00 am »

Cool. I guess I notice a *slight* speed difference.

Halifax: 6 million divided by 450,000
