i have just started using the DeltaYaw and DeltaPitch functions and i encountered a problem. I have a cube and i have a sphere the cube is rotated at a yaw value of DelteYaw(ball,cube) so that it will point at the sphere this all works fine until i rotate the ball if i turn the sphere the cube turns with it. is this supposed to happen, is there someway to make it stop?

Some code?

Maybe the cube should be rotated to deltayaw( cube, ball ) , rather than ( ball, cube ) so that the ball rotation has no effect on the cube.

DeltaYaw does not make the cube point at the sphere. It will make the cube look at the difference of their two angles, which unless the sphere never was rotated will not be the sphere! use pointEntity if you want to rotate it towars the sphere, or the atan2 and the difference in positions.
