I updated it to 11.3 and made it work with pre-converted glsl code.

I missed this project, awesome, thanks for updating it!

I get X mirrored. Any idea if that's fixable?

You can increase performance by remove love.graphics.draw call in love.update because it has no effect and you are already calling it in love.draw (in my case, it doubles FPS)

Well, I've fixed it with this:

 end

Also, I concur with Andlac028; I also get a 2x speedup when removing the love.graphics.draw line from love.update.

It happens only to me, that Löve simply crashes on love.graphics.newShader function runned in pcall with no message on shader "circle inversion laser.glsl"? (using LÖVE 11.3 on Windows 8.1, I can boot Ubuntu and try it on it too)

Update:
When I removed line 4:

Code: Select all

#define frame(u) camLens*(u-.5*iResolution.xy)/iResolution.y

Löve doesn't crash, only love.graphics.newShader returns error:

Code: Select all

Error: Error validating pixel shader code:
Line 121: ERROR: 'frame' : no matching overloaded function found 
Line 121: ERROR: '=' :  cannot convert from ' const float' to ' temp 2-component vector of float'

I'm glad I restarted the hype. I added more features and fixed a major bug. The shader was being rendered twice.
Made some other nice changes and things, didn't make a list

Now you can do more things
p = pause
v = toggle on/off vsync
f = toggle fullscreen
r = restart
1,2,3,... = switch monitors
