How to rotate an img based on a reference point?

[weilies]

I realized the love framework always based on point 0,0

Imagine I loaded arrow up image and rotate 30 degree, the rotation point suppose to based on the bottom of the img and not 0, 0 of the img

Look at http://love2d.org/wiki/love.graphics.draw

The last two parameters, ox and oy are the origin offset, around that point are images rotated.

When in doubt, read the wiki.

Then there's doing it manually...

Code: Select all

local angle;
local x,y;
local ox,oy;

local a,b=math.sin(angle),math.cos(angle) --Trig ftw.
local rx,ry=x+a*ox,y+a*oy;

If that doesn't work, blame my sugar rush from just drinking a LOT of pepsi.
