Topleft corner...

[worfox]

Hey, im new here and I got a problem:

I've got a box shape with a body, and now I want to draw an img over it. I can get the topleft corner with shape:getBoundingBox() if the angle is 0 of the body.
How can I get the topleft corner of a shape, even if it is rotated?

You rotate the image by the same angle that the body is rotated.

You rotate the image by the same angle that the body is rotated.

That's what I did, but it rotates around the topleft corner of the BoundingBox. I need the topleft corner of the shape!

I think what you need to do is to use the offset parameters in love.graphics.draw(): http://love2d.org/wiki/love.graphics.draw

Thanks Robin, it works

How it could work:

Code: Select all

the love.load part:
box = {}
box.img = love.graphics.newImage("img/box.png") --has to be a cube
box.body = love.physics.newBody(world, 325, 100, 30, 1)
box.size = box.img:getWidth( ) 
box.shape = love.physics.newRectangleShape(box.body, 0, 0, box.size, box.size, 0)

the love.draw part:
local x,y = box.body:getPosition()
love.graphics.draw(box.img, x, y, box.body:getAngle( ), 1, 1,box.size/2 ,box.size/2 )-- Offset is half of the size

Thanks Robin, it woks

Wow, that would be useful code.

You fail phpBB forever.

It took me 32 hours to get that joke.

I doubt that.

[nevon]

I doubt that.

How do you know I didn't look into the future?
