DisableMotor() method does not work in HingeConstraint.

[zhitongcui]

I enable a motor when I use a HingeConstraint method. However, I can not disable the motor anymore.
Here is my code:

setTimeout(() => test(), 2000)
setTimeout(() => hingeConstraint.disableMotor(), 5000)

function test() {
hingeConstraint = constraints[0]
hingeConstraint.enableMotor()
const velocity = Math.PI / 6
hingeConstraint.setMotorSpeed(velocity)
}

I intend to let one body rotate to a specific angle. Therefore, I start a motor and then stop it. Am I understanding correct?

Look forward to your reply. Thanks!
