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
How to rotate an img based on a reference point?

Re: How to rotate an img based on a reference point?
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.![Wink ;)](./images/smilies/ms-wink.png)

Then there's doing it manually...
If that doesn't work, blame my sugar rush from just drinking a LOT of pepsi. ![Death :death:](./images/smilies/ms-death.png)
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;
