Rotating mouseX,mouseY

phaidon

Do you know if there is any way of rotating mouseX mouseY as the object rotates?Always correspondents with the 2d screen

I believe screenX and screenY functions do the trick.

no it doesnt work,

phaidon

i just rotate the shape,and the camera still :P

phaidon

No that doesnt work either.The is a point where mouseX=-mouseX and is reversed

phaidon

i make it.Here is all the code,because i use pushMatrix,i had to cancel the first rotation and then put an other rotation after translation
