Make Vive controller vibrate when object is destroyed. SteamVR

Hey guys;
The web is filled with outdated and no longer working guides and it makes me loose hours every day in wasted time an I cant find ANY guide for this that makes sense.

I am building a Sword VR game in Unity and SteamVR. I have been trying for two days to get haptic feedback when my sword destroys an enemy.

I aim to put the trigger for the haptic on my enemy script:

GameObject[] newGOs = new GameObject[2];
            if (OptionalTargetObject == null)
            {
                newGOs[0] = Instantiate(gameObject) as GameObject;
                newGOs[0].name = gameObject.name;
                newGOs[1] = gameObject;
                NextTarget.SetActive(true);
//This is where I want the haptic command to go to give the controller a buzz.
            }

Thank you in advance! :slight_smile:

SteamVR is now directly supported by Valve, we suggest checking out their latest SteamVR plugin. Please post any questions you have on their Github so their team can address.

        SteamVR_Actions.default_Haptic[SteamVR_Input_Sources.LeftHand].Execute(0, 1, 10, 1);
        SteamVR_Actions.default_Haptic[SteamVR_Input_Sources.RightHand].Execute(0, 1, 10, 1);
