TileMap Brush 1.0 2D Tools 3.1 Community

Submitted by user vitmush; MIT; 2019-09-16

Provides editor's brush drawing functionality over TileMap

How to use it:
0. Install, and activate plugin
1. Add new child node to scene tree - called TileMapBrush
2. Configure 'Script Variables' in inspector:
* Draw/Erase Size (1 is default, and equals to 1 tile)
* Draw/Erase Brush Type
3. Now, in editor - press 'Left Mouse Button' to draw, 'Right Mouse Button' to erase

Known issues:
1. There's no UndoRedo for what you draw with brush - it supposed to be original TileMap workflow; but seems - it saves only 9 rounding tiles for undo, rest cannot be undone - use manual erase instead(I hope, solution will be found in future for that)
2. Some drawing points may be missed - due to mouse movement can be faster, than _physics_process' delta; TileMap still draw single tiles (can be fixed with line drawing between last and new mouse position; probably other solution can be found)
3. Some optimization can be done on get_cell_info() - refresh once per mouse hold

Additional info:
1. Some optimization can be enabled in TileMapBrushPlugin, by OPTIMIZE field
(you may not like to use it due to how it optimizes)
(not sure it actually adds performance)
