Context:

Right now, despite toggling either the entire gizmos off, or toggling gizmos off specifically for RoomTemplateSettingsGrid2D, the room outlines continue to draw in the editor scene view.

Problem:

The reason this happens is because currently the outline are drawn from a callback hooked into Unity's SceneView.duringSceneGui callback, which does not respect gizmos settings.

Solution:

To manage this, I've implemented the following checks in the onSceneGUIPersistent callback method:

• First check if all gizmos are turned off. If so, dont draw (return)
• Otherwise, check if gizmos are specifically turned off for this script (RoomTemplateSettingsGrid2D). If so, don't draw (return).
  • This check unfortunately is only possible from 2022.1 and on via the GizmosUtility. Before this version of Unity, solutions to do this seem to be quite hacky.
