This plugin implements autotile-style terrain system with multiple connections. It works with the existing tilemaps and tilesets alongside Godot 4 features.

Godot 4 has a terrain system built-in to its TileMapLayer nodes. This system has some tricky behaviors and is tailored towards a very specific usage of tilemaps, rather than a more general case. It's also quite slow, and the API is difficult to use at runtime. There are very large functional gaps caused by the replacement of the Godot 3 autotile system.

Better Terrain solves these problems by offering a straightforward alternative. It is more powerful, easier to use, and faster too.

Features:

• Full editor integration, so tiles can be configured and painted directly into your TileMapLayers.
• Easy script functions for placing terrains and calculating tiles.
• Versatile matching behavior, match terrains in numerous ways.
• A categories system to group terrains and match tiles between categories.
• A decoration system to automatically add decorative tiles.
• Symmetry rules to automatically rotate, flip, or mirror tiles to match easier.
• Support for all the unusual tileset types - hexagons, triangles, weird sized tiles, animated tiles, etc.
• A wrapper for C# support.
