Blitting Speed

Post by Giuliano »

Blitting is kind of slow. I have made a tile engine and when I draw all my tiles, it drops the FPS down by an incredible amt.

Are you guys working on different forms of drawing graphics w/ increased speeds? If so, when can such a release be expected ?

I really believe the Lua scripting language has potential for some higher end games and applications if it continues to be updated

i do not know how much you blit, but i blit on different layers
HUD (user interface and stats)
background (15x29 tiles @ 16px)
playground
explosions
sprites
players

NO speed-drops here
maybe you should have a look on your code and see where you can optimize id
note: use double buffer to perform blit & blit the buffered images to screen (or merge them before you blit it to screen)
so only few blits are left onto the screen (which solves any flicker)
