[Solved] Damping / Drag not work

Create a ship with rotation and accelerate and it should slow down if no key is pressed (damping).

Damping / Drag with rotation works:

player = this.physics.add.image(200, 300, 'player')
player.setDrag(0.5, 0.5)

// rotate
// and it slows down

But slow down with acceleration not:

// accelerate with
player.body.acceleration.setToPolar(player.rotation, 100)
// or
this.physics.velocityFromRotation(player.rotation, 100, player.body.acceleration)

the ship moves without slowing down.

Did somebody has an example for this?

Found the problem, i forget to set player.setAcceleration(0) when nothing is pressed.
