[edit] Description
This is a simple night vision system (green color)
Requires Unity PRO. This script uses texture rendering and Post-processing only available in Unity Pro
[edit] Usage
- Luminence: green luminence.
- Noise Factor: factor of noise for the vision.
[edit] C# - GreenNightVision.cs
Script for Camera Renderer:
using UnityEngine; [ExecuteInEditMode] [AddComponentMenu("Image Effects/Night Vision")] public class NightVision1 : MonoBehaviour { // public data public Shader shader; public Color luminence; public float noiseFactor=0.005f; //private data private Material mat; //----------------------------------------- // start void Start() { shader = Shader.Find( "Image Effects/Night Vision" ); mat = new Material (shader); mat.SetVector( "lum", new Vector4( luminence.g, luminence.g, luminence.g, luminence.g) ); mat.SetFloat("noiseFactor", noiseFactor); } //----------------------------------------- // Called by camera to apply image effect void OnRenderImage (RenderTexture source, RenderTexture destination) { mat.SetFloat("time", Mathf.Sin(Time.time * Time.deltaTime)); Graphics.Blit( source, destination, mat ); } }
