Determine if hinge motor reached limit

Questions & Answers
1

I need to check if my hinge joint motor reached one if it’s limits and which.

I tried to use HingeJoint.angle and HingeJoint.limits.max/min for this. But my joint angle is not 0 at the beginning of the simulation and is not between the limits (altough the limits work!).

Can anyone help me with this problem?
Thanks

Hey. If someone is interested… I maged to do that with an invisible trigger that touches the object when it reaches the li its.

Hi,
I was seaching the same answer and i find this :
hinge.angle

Hope it helps

private HingeJoint 		hinge;

void start(){
hinge = GetComponent<HingeJoint> ();
}

void checkAngle(){
if(hinge.angle == hinge.limits.min){
// Do Something
}
}

Just want to add something that seems to roughly work as well. You can just check against object rotation. Say if you have limits 0 and 30, then your hinge joint reached peak when your rotation (tried it for 2D, so was Z axis in my case) is < -30. This assumes your object starts with 0 rotation in given axis. If this is not true, then just subtract the range of your limits from your initial rotation.

Again example, if your object Z rotation is say 20, with hinge joint limits 0 and 30, then you reached peak for -10 and so on.

Hope it helps.
