LÖVE

with what 3:?

lol, you wrote it!

to zoom in, decrease their values, to zoom out, increase them. E.g. multiply all of their values by 0.9 to zoom in, 1.1 to zoom out.

And if creating the Fractal takes too long, with some work you could also make it so it will update and draw a progress bar while it is calculating by taking advantage of calling stuff like love.timer.step(), love.graphics.clear(), drawing your progress stuff to the screen and then love.graphics.present(). That might be more advanced, but when used properly it can be useful. It can be called inside any process that takes a while. You just don't want to call it every loop since it slows the thing down, instead you call that stuff every certain loops. Like every 10 or every 100. Since the loop works much faster than a normal frame does, you could go through a thousand loops in a few frames time. So you could even call it every 1000 iterations and still have a pretty good progress indication. And it doesn't have to be a bar, it can be a spinner or a simple message that says "Calculating! Please wait..."

Or if coroutines aren't your thing. simply use a thread.

i tried changing the xmin,xmax,etc
but all it does random crap..

this is what i have now =

Simply? Aren't threads a lot harder to figure out how to code? I know I've never known how to use them. Tell me how!

multiplication ~= addition

kraftman,

ur not making sense right now, explain please -__-

I said multiply, and you are adding.

whats the diffrence?!
your in both ways making the numbers bigger/smaller
and even when i do that, it WONT work.
