Just a question, how many warnings do I need (4, 5 or 6?) to be banned? and is it permanent?

love.filesyste.enumerate was replaced by love.filesystem.getDirectoryItems in 0.9.0

Yeah but with that last example you only can draw a pixel once (it's an example, I know, just saying).

For the moment, it only works with png images and not with a special type of file (for the editor, the animation is 2 files together, the png image and a text file with the info). Here's the first update I made a few days ago:

Your performace will always be by soil if you're using ImageData and manipulating it in real time (at least you use a low resolution or have a monster machine), even worse if you make a real image an draw it each time you draw a pixel on screen. Look this, I'm using a 2D array here to draw in real t...

If you're using Windows, sometimes there's a kind of bug which makes yor first frames pass really fast and after a little time, pass at normal velocity (it happends to me once, on Linux I don't have that problem, I guess for the native OpenGL libraries).

Remember that the penultimate parameter of newAnimation is the delay of each frame, if you change it from 0.1 to 0.2, the animation will run at half speed.

If you want to do something different, it's a good idea, go on, but you should choose the proper tool to do it.

If you're making a music player, you shouldn't be using löve... just saying.

you could use something like a ball_retained flag to control when the ball must move along the paddle in th update method.
