CameraViewer

By AngryAnt.

Description

Note: Unity Pro only.

Install in Assets/Editor to add a "Camera viewer" item to the "Window" menu. Clicking this will launch a window which renders the output of the selected camera GameObject.

Component code

<csharp>using UnityEngine; using UnityEditor; using System.Collections;

public class CameraViewer : EditorWindow { bool liveUpdate = false; Camera camera; RenderTexture renderTexture, originalTarget;

[ MenuItem( "Window/Camera viewer" ) ] static void Launch() { EditorWindow editorWindow = GetWindow( typeof( CameraViewer ) );

editorWindow.Show(); }

public void Update() { if( camera != null ) { camera.Render(); if( liveUpdate ) { Repaint(); } } }

void OnSelectionChange() { Camera newCamera = ( Selection.activeTransform == null ) ? null : Selection.activeTransform.gameObject.camera;

if( newCamera != camera ) { if( originalTarget != null ) { camera.targetTexture = originalTarget; }

camera = newCamera; if( camera != null ) { originalTarget = camera.targetTexture; camera.targetTexture = renderTexture; } else { originalTarget = null; } } }

void OnGUI() { if( camera == null ) { ToolbarGUI( "No camera selection" ); return; }

if( renderTexture == null || renderTexture.width != position.width || renderTexture.height != position.height ) { renderTexture = new RenderTexture( ( int )position.width, ( int )position.height, ( int )RenderTextureFormat.ARGB32 ); camera.targetTexture = renderTexture; }

GUI.DrawTexture( new Rect( 0.0f, 0.0f, position.width, position.height ), renderTexture );

ToolbarGUI( camera.gameObject.name ); }

void ToolbarGUI( string title ) { GUILayout.BeginHorizontal( "Toolbar" ); GUILayout.Label( title ); GUILayout.FlexibleSpace(); liveUpdate = GUILayout.Toggle( liveUpdate, "Live update", "ToolbarButton" ); GUILayout.EndHorizontal(); } } </csharp>
