Sorry, I think in degrees. So I usually convert my degree numbers to radians. Yes, 90 degrees would be half pi. 180 would be pi. And 270 would be pi and a half. 360 would be 0 or two pi... mmm... I wish I had 2 pi's...

Code: Select all

math.tau = math.pi * 2
math.tau -- 360 or 0 deg
math.tau / 2 -- 180
math.tau / 4 -- 90
math.tau / 8 -- 45
-- and so on...
It's easy to remember because if you replace math.tau with 1 in your head, that's the fraction of a circle you get.

I knew you'd say that when I read Jasoco's post.

I still prefer to use degrees.

Ha ha, but what's wrong with Tau? It's better than Pi (and hey, you get twice as much pie too! ).

I prefer pi (that is to say, radians) to tau, degrees, quaternions, or anything else.

Why's that? I'm interested to know. How is $\frac{\pi}{2}$ to make a quater circle more logical than $\frac{\tau}{4}$?

And yet again, more problems. Now the characters face isnt looking at the mouse, but the characters top left corner is.

I got it working by using the love.graphics.draw function's offset x and offset y.

Thanks guys!
