How To Force an Inspector to Repaint

Questions & Answers
1

In an inspector I’m invoking a Coroutine. When the Coroutine finishes I want the Editor to Repaint(). However, calling Repaint() from the Coroutine’s callback doesn’t Repaint(). Is there a simple solution to this that I’m missing?

Thanks,

the only way I’ve found to do this, consistantly, is to override the Editor’s RequiresContantRepaint function
eg

override public bool RequiresConstantRepaint() { return (repaintCondition1 || repaintCondition2); }

Wow, I love how I’m not good enough to comment on a reply in a thread I’ve started…

@Glurth, I’ve tried to override UnityEditor.Engine::RequiresConstantRepaint() but that doesn’t get the update to occur. Which makes me think this isn’t the actual problem… I need to do more digging.

I will post what I find.

I’ve written a short workaround for how the Unity editor handles yield instructions within the editor space (shown below):

protected System.Collections.IEnumerator CoQuery()
{
    bool bStillWorkingOnSomething = true;

#if UNITY_EDITOR

    if (!Application.isPlaying)
    {
        while (bStillWorkingOnSomething) 
        {
            /* When done doing what your doing... */
            bStillWorkingOnSomething = false;
        }
    }
    else
    {

#endif // UNITY_EDITOR
    
        yield return new WaitForSeconds(1); // Or something similar...
    
#if UNITY_EDITOR

    }

#endif // UNITY_EDITOR
}

Hopefully, this can help someone in the future.
