Thanks for these informations. I actually opted for physical behavior.
I managed to get my two changes of state (ball and triangle) to change in the same direction and at the same speed, but I still have difficulty in moving the triangle (rear drive and 360 drift degrees when the right and left keys are pressed).
It would be necessary that when the triangle rotates even hypothetically 180 degrees, it should be able to communicate its speed to continue its course.
I tried applying force from behind (like jet engines) and angular velocity. It works with X or Y coordinates, but it only works when the triangle points up (X) or sideways (Y). This would have to be the case at 360 degrees.
Do you have any leads on this?
