I sort of figured that out but your code is much better.
Attached is my attempt to see how far I could push the existing code (definitely not an end product or attempt to steal your thunder.)
Waiting for rolling text in a box {O^O}
Thanks

Hi litearc! Not sure the use of '|n' works the way you intended. If '|n' is placed in the string, the resulting text box will have a line break at that point AND a subsiquent line break at the point where the line would have wraped if no '|n' had been inserted - leaving a line fragment. tttttt|n|ttt...

Just jumping the gun here. I added to my copy hard coded width & heights for window. Not pretty, but gets the job done. Sure final version will be much more automatic. cfg.w = {200,200,200,100,200,200,200} cfg.h = { 80, 60, 50, 60, 80, 60, 60} Window drawing then becomes: for i = 1, #m do if not...

I like litearc's approach for hex color conversions

Two items. 'z' key doesn't allow you to break out of a time delay line (e.g. s[2]). I find that if you replace: if cfg.textsh then -- add character shadow (if desired) lg.setColor( color.shadow) lg.print( self.s:sub( 1, nc ), x + self.x + 1, y + self.y + 1) end with local sh = 0.1 if cfg.textsh then...

Very interesting project. Afraid I'm not too good at explainations so just created a temporary 'LOVE' to show what I'm suggesting. All changes are commented. Just thought that the window location should be more easily modified and that it's size should reflect what is being displayed. Got the width ...

Just a varient of vrid's metaballs.
Don't really know how you would use it in a game.
Leave that up to the more eventuresome.

Oh no! Another shader.
Just a cross between 'tunnel' and 'shockwave'.
For what it's worth.
Played with meatballs(metaballs) but still haven't got complete control over it.
Are there other hidden features in GLSL?

Hi! Two quick questions. Has anyone used 'kernels' with PixelEffect(is it possible)? The IM library has: image, error = im.FileImageLoad(filename) r,g,b,a = image[0],image[1],image[2],image[3] Does Love have a similiar way to get the red, green, blue & alpha channels. I know about: r,g,b,a = lov...

Ok!
Just another (not too bright) example of PixelEffect.
Falls into the pigless 8 second category.
If you get tired of seeing random spots before your eyes, just hit 'r' and arrow keys & 'a'/'s' keys are available.
Still struggling with syntax for GLSL effects but coming slowly.
