Debug.DrawLines() - how does it work?

Unity Engine
1

Hello,
I writing an editor which draws a lot of lines in scene view every frame. To do it I use Debug.DrawLines() within Update() of EditorWindow class. It draws about 400 lines in Scene per frame and it looks like these lines are not erased before next frame. After a while a warning appears:

vertexCount > 60000
UnityEditor.Handles:Internal_DrawBuiltinGizmos()

How can I draw such lines in scene view (every frame) efficiently?

Sorry of my English

I’ve never used Debug.DrawLine. If I needed lines in a scene, I would program it like this:

  1. create a cube with scale like (0.1, 0.1, 100). That will look like a line onscreen.
  2. apply a material with the color that you want
  3. make that into a prefab, in your Resources directory (so it’s simple to instantiate)
  4. during Update(), instantiate or destroy or reposition as many as you need to. You will need to position and rotate each one relative to the camera, and alter the scale-z value to change each one’s length
