Catch Grid Editing Events in Editor Mode

Hey Guys,

I would like to create a little helper to my level editor for my game. I use Grid and Tilemap and what I would like to do is to run some code when hovering over the Tilemap with supposedly dropping tiles on the Tilemap. So without actually the need to place those tiles, I would like to run my algorithm to see if the place is optimal in there or not.

Is there a way to capture that hovering event in the Editor Mode and then get the Tile or Tiles that were selected from the Tile Palette?

 

You can do that using a scriptable brush, and the OnPaintSceneGUI callback. This manual page shows an example usage. The example just draws a preview of the tiles, but you can just as easily run your algorithm. https://docs.unity3d.com/Manual/Tilemap-ScriptableBrushes-Example.html

 

Awesome, let me check that out, thanks!
