Slightly offtopic but does anyone knows how to smoothly change an .exes icon on Linux? Preferable without Wine?

Why dont you just make a table that holds all the confetti particles, update all of them for things like movement of the confetti particles and then draw all of them using a SpriteBatch, setting thier individual colors with SpriteBatch:setColor( r, g, b, a )? You mean something like creating a tabl...

and if you want the bounding box adapt to your text, use
width = Font:getWidth( text ) to get the texts width
height = Font:getHeight( ) to get its height
love.graphics.getFont() to get the current font

Sadly, so far I know there is no setColor function for particle systems. If the particle system is simple you could use a spritebatch instead. Ah that's a shame. Then I have two options. Would it be more efficient to create a new particle system for every color I want or new sprites? New sprites. T...

You could use an atlas with several colored stars, then supply the quads with particleSystem:setQuads(). I could. I was just hoping to have the color be set by love2d. I'd prefer not to make whole new assets if I forget a color or something. Sadly, so far I know there is no setColor function for pa...

So we need the full code, at least the lines from where you call the update function.

Also you do not need extra parentheses for the if statements in lua

As raidho34 said, I just limited the x and y loop. Usually drawing outside the screen (images) won't really affect the performance, this is already handled by the GPU (or something before, I'm not sure). But text requires some pre processing. So don't check every image manually. Limit mass draws lik...

Well, depends on CPU and GPU. The best way, if the tiles are small, is to use canvases. Render it once, then draw the entire canvas. This way there is no real limit. If your tiles are animated or too big, use a spritebatch and a texture atlas. Or use both, for example when zooming in, use the sprite...

Works fine for me. Windows 10, LÖVE 11.2.
Do you have any error messages?
