Question by psychentist · Feb 17, 2012 at 11:00 PM · hinge joint

Actual name of target velocity?

Ok, so I'm trying to directly modify the target velocity of a hinge joint (HJ). I've tried a few things like "HJ.TargetVelocity = 500" and "HJ.targetVelocity = 500" and "HJ.Target Velocity = 500"... You know the routine.

So, what is this variable actually called? I know there are some texturing variables that have different names in the code than what shows up in the inspector. Here's a snippet if it helps understand my question.

 var firing : boolean = false;
 var HJ : HingeJoint;
 
 function Start () {
 HJ = gameObject.GetComponent (HingeJoint);
 }
 
 function Update () {
 
 if (firing){
 HJ.targetVelocity = 500;
 }
 
 else{
 HJ.targetVelocity = 0;
 }
 
 
 }

AHA! I found it. Here's the correct code.

 function Start () {
 HJ = gameObject.GetComponent (HingeJoint);
 }
 
 function Update () {
 
 if (firing){
 HJ.motor.targetVelocity = 500;
 }
 
 else{
 HJ.motor.targetVelocity = 0;
 }
 
 
 }



As you can see, I just needed to add the .motor. , and use the normal scheme of lowercase, then capitals. Duh. Oh well, I'll leave this up, maybe it will help someone else.

The docs only mention a velocity variable.
