    How do you force redraw on Scene window? As some of my debug draw lines are visible even after commenting them.

    This is probably if anything a recompile issue, rather than a redraw issue. Are there any errors in the console? You could also try reimporting the script in question.

    No problem with compilation, added several codes, all are working fine.

    If you move something in the scene, or set an object's position (even just to its current position), that seems to invalidate the scene view so Debug lines are cleaned up.

    Not positive if the object you are moving has to be within the scene view camera's frustrum or not.

    Also toggling effects for the scene window manually (little button on the top edge of it) can sometimes work.

    Whenever I update my Debug or Gizmo code, I find that all the widgets, such as camera, lights, and Gizmos, in the scene view disappear, for some reason, until I change my selection.

    After that, check for error messages. The way Unity works, it refuses to do most tasks, even adding scripts to objects, until the error(s) are resolved, at least the last time I checked. I think it has do do with how Mono compiles everything at once. Apparently one bad script ruins the barrel.

    If all else fails, I have seen Unity simply not recompile a script, normally with an error message that won't go away. The fix to this is to adjust the script, I normally delete a semicolon, to force Unity to recompile the script. After Unity acknowledges the error, fix it and resave. That clears any sticky compilation. Simply reimporting the script might also work, but I like the feel of vengeance that comes with intentionally inducing a syntax error. :wink:

    Hope it helps.

    I had a similar issue, being unable to force redraw Debug.DrawLine calls via scripting. They would just draw on top of each other rather than clear and redraw as they do using the editor.

    Solution was to translate the GameObject in question by nothing to force a redraw:

    transform.Translate(new Vector3(0,0,0));
