From the image, it looks like it also optimizes the path

move image y coord to y + 10
setColor from {1,1,1,1} to {1,1,1,0} before drawing the image

you can probably use https://github.com/kikito/tween.lua
(note: image may not appear smooth with non integer y-coord)

It is understandable if you want to hide your code. It is really stressful when other people see your code and criticize it.

window title can contain if black or white should move

Code: Select all

I come up with something smart but it is already implemented and optimized

string.format looks cleaner and probably uses sprintf (which might be better than a train of luaconcats)

It is not. Also it is GPL.

you need to add __tostring metamethod to your userdata in C
or manually turn it to string in lua without using tostring
