Godot 4 (.tscn)

The Godot 4 exporter writes a scene file with a TileMap node and a TileSet sub-resource per atlas. Open the .tscn in Godot 4.2 or newer and the map shows up ready to run.

What's covered

• One TileSetAtlasSource per GridCraft tileset, sharing a single TileSet sub-resource.
• Per-tile flip and rotation bits encoded in the alternative-tile field (Godot 4.2+ native encoding).
• One layer_N/tile_data per GridCraft tile layer.
• Variable-size tiles via size_in_atlas. Anchors and covered cells are handled so Godot doesn't reject the tileset.
• Object layers exported as child Node2D instances under the root, with custom properties as metadata.

Pack format

Tile data is a PackedInt32Array with three integers per non-empty tile:

DestLocation = (x >= 0 ? y : y + 1) * 65536 + x
SrcX         = atlasCol * 65536 + atlasSourceId
SrcY         = atlasRow + 65536 * (flipBits << 12)

flipBits:
  bit 0 = flip horizontal
  bit 1 = flip vertical
  bit 2 = transpose (anti-diagonal)

Image paths

Each tileset image is referenced as res://<original-path>. You'll usually want to move the images into your Godot project and adjust the path before running.
