I thought tonumber(a) serves this purpose, and # is for element count in the table. Am I wrong?

I'm bringing my apologizes if this counts as double-posting but I need to reply. Found it interesting that you used a stencil to confine the blur to the shape. Cleaver! Actually this is a common technique in vector graphics. I've learned this sometime ago when studying SVG or playing with Inkscape, ...

You're welcome. I'm always glad to help.

Try to change line 35 in the player.lua to:

world.bump:add(self, 0, 0, math.floor(self.width / 3), self.height)

I'm experimenting with Beziers and blur shaders.
UPDATE: faster blur shader (now uses built-in variable VaryingTexCoord)
UPDATE2: added self-intersecting bezier (right click close to point and drag)

Actually I've started with my own engine and ended up with using LÖVE for most part of it.

I'm already using SQL on my main job for several years so know language well enough. Fair, I really can't understand how to live without SQL now! In any project. SQLite is fast, cross-platform, compact, flexible and powerfull. Project will come with standard assets database (textures, sounds, models...

And about content generation in my project: planned tileable texture creation (like in Allegorithmic's "Substance Designer" & friends + cubemaps creation, procedural vector graphics, etc.)

One more thing.
Of course I would like to see sqlite integration, but already read here on the forums that it is not possible, so I will use customized version of framework.
