How to get local point inside a body where mouse click occurred in box2d?
- by humbleBee
I need to find out the point inside a body, lets say a rectangular object, where the mouse was clicked on. I'm makin a game where the force will be applied depending on where the mouse was clicked on the body. Any ideas?
Will body.GetLocalPoint(b2vec2) work? I tried by passing the mouse coordinates when the click occurred when inside the body but if the body's position is (400,300) in world coordinates then for trace(body.GetLocalPoint(new b2vec2(mouseX,mouseY)).x); I get some value between 380 to 406 or something (eg. 401.6666666). I thought getLocalPoint will give something like x=-10 when clicked to the left of the centre of body or x=15 when clicked to the right.
Language is As3 btw.
