WebNov 19, 2012 · Description First we get the distance between the sprite and the mouse. This is obtained simply by subtracting the mouse location from the sprite location. We then take the atan2 of the resulting coordinates. One warning with atan2, the parameters are (y,x) not (x,y)! Atan2 will return the angle, with a few gotchas. WebMar 24, 2015 · \$\begingroup\$ Thanks, you are right, I placed my white rectangle differently and the result looks good... in the logs. Inside the white rectangle, I added a camera. I think I need to rotate the camera first by 180degrees, which I did. But I now need only the rest of the angle, that goes until 2 pi. tenby resource initiative
