How to throw objects in the correct direction?

Hey guys,

I am currently writing a code for the Vive. I have wrote a script to pick up and throw objects. However, I have trouble getting them to move in the right direction.
I tried TransformVector and TransformDirection to get the vectors in world space but it is still not working like I want it to. This has been killing me for awhile now and I have absolutely no idea what's wrong.

Code (CSharp):

1.   void OnTriggerStay(Collider col2)
2.     {
3.         //Release Object
4.      
5.         if (SteamVR_Input._default.inActions.GrabPinch.GetStateUp(SteamVR_Input_Sources.LeftHand))
6.         {
7.             string parent = col2.transform.parent.name;
8.             col2.attachedRigidbody.isKinematic = false;
9.            
10.             col2.isTrigger = false;
11.             col2.transform.parent = null;
12.             if (parent == "Controller (left)")
13.  
14.             {
15.                 Vector3 LControlV= transform.TransformDirection(PoseData.GetVelocity(SteamVR_Input_Sources.LeftHand));
16.                 Vector3 LControlAV = transform.TransformDirection(PoseData.GetAngularVelocity(SteamVR_Input_Sources.LeftHand));
17.                 col2.attachedRigidbody.velocity = LControlV;
18.                 col2.attachedRigidbody.angularVelocity = LControlAV;
19.             }

 

why don't you simply attach (parent) the object to your controller?

-ch

 

I didn’t include the code here but that was what I did actually. That’s why I used ‘col2.transform.parent=null’ in the code above when trying to throw the object. Right now, I am trying to add velocity once the object is thrown but the direction is wrong.

 

Ah. Is it possible that PoseData.GetVelocity already returns it's value in world coordinates? If so, your additional TransformDirection will interfere.
