Editor camera events

Hello,
how can I plug in this code into editor's camera tryed googling but didnt find anything :

• using UnityEngine;
• using System.Collections;
• [ExecuteInEditMode]
• public class NavDebug : MonoBehaviour {
• 
  
• void OnPreRender(){
• GL.Begin(GL.TRIANGLES);
• //draw code
• GL.End();
• }
• }

 

Hey there,

Are you just trying to draw lines as helpers in the edit view?

 

I'm trying to draw Triangles oops I will edit

 

There is good news!

Unity has a lot of built in shape and line drawing tools called Handles. They are used for this purpose.

Docs
http://docs.unity3d.com/ScriptReference/Handles.html

Here is the page talking about drawing lines.
http://docs.unity3d.com/ScriptReference/Handles.DrawPolyLine.html

Regards,

 

Hmm I cant see function for drawing Triangles

 

You will just have to create 3 points in space and draw a line between them using DrawPolyLine. You can create a helper function pretty quickly if you need to do this a lot.

 

However the triangle won't be filled right ?

 

If you want it filled you can just

use http://docs.unity3d.com/ScriptReference/Handles.DrawSolidRectangleWithOutline.html

and make two of the verts the same.

 

hmm the problem I found after figuring things out is that I must have the Object selected In order to draw the triangle.As OnPreRender method suggests I want to draw the triangles all the time.

Even though It was good experience to learn how to use Unity Editor I lost lots of time .Could somebody tell me what I asked and not go around my question I asked at first place.
