// grenadeLauncher.js
// examples
// Created by Ben Arnold on 7/11/14.
// This is a modified version of gun.js by Brad Hefta-Gaub.
//
// Copyright 2013 High Fidelity, Inc.
//
// This is an example script that turns the hydra controllers and mouse into a particle gun.
// It reads the controller, watches for trigger pulls, and launches particles.
// When particles collide with voxels they blow little holes out of the voxels.
