Re: Problem with atan2
Hi, Well, I guess I am getting rusty. There is been a long time I have played with LÖVE, and I forgot another minor detail. Added to the fact that y coordinates are flipped upside down, rotation is clockwise, and I was assuming it was anti-clockwise. This should hopefully work. :awesome: function l...

Re: Problem with atan2
My bad. Just use the return value of math.atan2(dy, dx) straight as the rotation argument to love.graphics.draw. function lookAt2(obj, target) local dx = target.x - obj.x local dy = -(target.y - obj.y) -- same as obj.y - target.y return math.atan2(dy, dx) --return rad < 0 and rad + math.pi*2 or rad...

Distributing binaries (again)
Friendly greetings (: I just started using Love2D (still playing with bubble wrap) but so far I LÖVE it. I just read wiki page about distributing games and to me it looks like we are distributing game with a source code (well at least Mac version). So I did quick search in forum and found some old t...
