Brain Dump on Node.js - Getting Started

This video tutorial is a basic example on using Raycasting in Unity.
Source code here: https://github.com/jasonrwalters/Unity_Raycast
using UnityEngine; using System.Collections; public class TargetDetection : MonoBehaviour { private Transform tr; private float rotY; private bool targetHit; // Use this for initialization void Start() { // reference components tr = GetComponent<Transform>(); } // Update is called once per frame void Update() { // draws the forward facing direction // you do NOT need this to raycast, just for debug purposes DrawForward(); // handles object rotation on the y axis rotY++; if (rotY > 360.0f) rotY = 0.0f; tr.eulerAngles = new Vector3(0.0f, rotY, 0.0f); // raycasting RaycastHit hit; Ray ray = new Ray(tr.position, tr.forward); if (Physics.Raycast(ray, out hit)) { if (hit.collider.name == "Target" && !targetHit) { Debug.Log("Target was hit!"); targetHit = true; } } else if (targetHit) { Debug.Log("Nothing was detected."); targetHit = false; } } void DrawForward() { Vector3 forward = tr.TransformDirection(Vector3.forward) * 2; Debug.DrawRay(tr.position, forward, Color.green); } }
