Pianoman, a tip to speed it up: change the white in the sprites with alpha (if you don't do this aready)
Wait, what?

Well, with alpha I mean transparency. The image draw routine will just skip the pixels instead of decoding the color value and drawing it. I used this in my card game, and I got almost 500% speedup (there is allot of white in the cards).
You can change the white to alpha with my online sprite editor

Hmmm, interesting.
However, the ghosts aren't TI.Images

Will that still work?

What are they?

fb39ca4 · « **Reply #63 on:** August 26, 2011, 12:02:25 am »

Do you draw them with geometric primitives?

Jim Bauwens · « **Reply #64 on:** August 26, 2011, 04:09:27 am »

This trick only works with TI.Images.
Drawing simple stuff with rect and circle is much faster, so in your case I guess you are fine.

Yes lol he did :

end

However, looking at what the final shape of the ghost looks like, I think I would have done the drawing differently :
- draw the top semi-circle
- draw a square under it, for the bottom part,
- draw white triangles at the very bottom

^ that's all

DJ Omnimaga · « **Reply #66 on:** August 26, 2011, 10:51:14 pm »

Ah right that's what I guessed he did. Personally I would be tempted to use sprites, since I would be able to put more details in them, such as SNES-like graphics.

Adriweb · « **Reply #67 on:** August 27, 2011, 05:24:17 am »

Sprites are obviously better but TI's image format s*cks *ss. And for now, it's slow...

Levak · « **Reply #68 on:** August 27, 2011, 12:44:46 pm »

+1, look at my Nyan Cat game, sprites blink as it is slow...

Hmmm, that's interesting... I'll try that.

And yeah, I'd love to use sprites, but that would make it unbearably slow

Hmm this is an inactive topic, but thing is the Monopoly nspire userbar on pianoman's sig, led me to this very topic. Bit misleading.

I have seen a pacman lua, though some elements of that particular pacman game could have been improved.
