Debug.DrawRay() does not draw rays in game view

Here is the relevant code:

Code (csharp):

1. protected override void Update()
2.     {
3.         base.Update();
4.  
5.         Debug.DrawRay(this.transform.position, this.transform.forward * 100f, Color.red, duration: 2f);
6.     }

When running the game, I can see the ray being drawn in Scene View.

However, in Game View, no ray is displayed.

As you can see from the screenshot below, I have already enabled gizmos in Game View.



What should I do to ensure that rays are being drawn in Game View when debugging?

 

You can't see the ray in GameView. Instead you can use a LineRenderer.

 

Thank you for your reply! Using the line renderer means that the line will also show up in the deployed build, no? I can of course delete those parts again, but it is a hassle.

You can show the debug draw stuff - in editor that is.
For example, this works just fine in editor's game view if Gizmos button is pressed:

Code (csharp):

1.  
2. void Update()
3. {
4. Ray ray = new Ray(transform.position, transform.forward);  
5. Debug.DrawRay(ray.origin, ray.direction * 10, Color.yellow);
6. }
7.  

There must be something else going on.

 

Debug is designed for debug purposes, in development. Not as if player should see it. So in case of Debug.DrawLine, you look into scene, not the game itself. Change tab to scene at runtime, or add another scene window panel.

LineRenderer is an game object, with defined number of vertices and their potions. It is not strictly for debugging, but can be used for it too. Then you do with that LineRenderer GameObject, whatever you need. Show hide, set color texture, sqeez, change vertices positions etc.

 

Another option is the GL API.

 

Hi
I imagine it's solved, but maybe could be helpful to others. When Debug.DrawRay
REMEMBER TO PUT THE TIME OF THE RAY OR IT LAST FOR ONE FRAME!!!

that basically take me my time to read the documentation
https://docs.unity3d.com/ScriptReference/Debug.DrawRay.html

Happy Debugging

Thanks. Gizmos button solved my problem
