Forest Editor - DropToGround Brush (Updated)

Just something I attempted to make that may help with readjustments to the forest elements after being placed. This will help all those who like me make terrain changes after placing everything and not wanting to manually drag all those objects out or erase and start again.

//game/tools/forestEditor/main.cs
//line: 50
   %map = new ActionMap();
   %map.bindCmd( keyboard, "1", "ForestEditorSelectModeBtn.performClick();", "" ); // Select
   %map.bindCmd( keyboard, "2", "ForestEditorMoveModeBtn.performClick();", "" );   // Move
   %map.bindCmd( keyboard, "3", "ForestEditorRotateModeBtn.performClick();", "" ); // Rotate
   %map.bindCmd( keyboard, "4", "ForestEditorScaleModeBtn.performClick();", "" );  // Scale
   %map.bindCmd( keyboard, "5", "ForestEditorPaintModeBtn.performClick();", "" );  // Paint
   %map.bindCmd( keyboard, "6", "ForestEditorEraseModeBtn.performClick();", "" );  // Erase
   %map.bindCmd( keyboard, "7", "ForestEditorEraseSelectedModeBtn.performClick();", "" );  // EraseSelected   
   //RPG Edit
   %map.bindCmd( keyboard, "8", "ForestEditorDropToGroundModeBtn.performClick();", "" );  // DropTheBeat

      %mode = ForestTools->BrushTool.mode;
      switch$ (%mode)
      {

            ForestEditorEraseSelectedModeBtn.performClick();

         //RPG Edit
         case "DropToGround":
            ForestEditorDropToGroundModeBtn.performClick();
         //RPG END
      }

Notes:

I wanted to add an adjustable sink like in the orginal add code. Currently it's hard coded to 0.5.



Edit:

Forgot about my video obsession:
