Hey superku !
i dont use the A6 template scripts, so my engine doesnt recognize "my_shadow" .
However,I finally achieved to turn the pan of my shadow as the little toon turn , with a part of your help .
In fact, i finally tried to use cosinus for angles , and this time it worked.
There is another problem that i encountered !
Since the shadow is an instance of the little toon model , i thought that i could shrink it flat to the ground , no matter how it would be oriented in the world.
But i cant find a way to shrink it arbitrarily! in order to let the shadow be always flat to the ground.
There are only scale_x, scale_y ???
I found out this problem because when i achieved to turn the pan of the shadow, it would turn like a flat model would turn.
