Raycasting Demo (like Wolfenstein3D, just veery basic)

No I meant what I said, love.graphics.print is pretty slow. (and it seems love.graphics.getFPS is as well)

EDIT: It is pretty ironic and deep as well though, thanks for pointing that out.

A really good optimization to raise FPS is to not draw anything.
Try it, cut out everything but the line the prints FPS. It will be huge!
This post was useless by the way.

Since when is love.graphics.print slow? I use it all the time and never notice any slowdown. And my game draws 32x32 tiles many many times each frame as well as text for the status bar and text dialogs.

I don't know, it appears to be, we even have a bug report for it. And, if you try it you'll see it actually does increase the FPS (it's visible, somehow I suspect the game to not use dt)

Is this only in 0.6.x? Because 0.5.0 is fine for me. Or is it an OS specific bug? (I'm on OS X still using 0.5.0 for my game.)

to print FPS in a windowed program use

Code: Select all

love.graphics.setCaption(love.timer.getFPS())

[bartbes]

Led to same performance decrease, hmm ironically it might be getFPS after all... (or my computer is doing weird shit, which is entirely possible of course)

Hmm. Has anyone looked at the math yet? I know that some raytracing/raycasting engines would use pre-calculated look up tables to shave processing time off.

I certainly haven't, though I recently saw something about someone who calculated only one wall and used a trick to get all other walls from it.
