How To Create Auto Tiling In Godot In less than 2 minutes! || Weekly Godot Challenge #24

Introduction

This tutorial will guide you through the process of creating auto tiling in the Godot game engine. Auto tiling simplifies the design of tile-based environments, allowing for efficient and seamless tile placement. Whether you're a beginner or an experienced game developer, this guide will help you implement auto tiling in your projects quickly.

Step 1: Set Up Your TileMap

• Open your Godot project and create a new scene.
• Add a TileMap node to your scene.
• In the TileMap properties, set the size of your tiles according to your design (e.g., 32x32 pixels).

Step 2: Create a Tileset

• Right-click in the FileSystem panel and create a new folder for your tiles.
• Import your tile images into the new folder.
• In the TileMap properties, click on the "Tile Set" property and select "New TileSet."
• Open the TileSet editor by double-clicking the newly created TileSet.

Step 3: Configure the TileSet for Auto Tiling

• In the TileSet editor, click on "Add Texture" and select your tile image.
• Use the "Create Single Tile" option to define each tile.
• For auto tiling, you must create a tile set that includes different variations for edges, corners, and center tiles.
• Use the “Autotile” feature by clicking on the tile and adjusting the settings:
  • Set the “Bitmask” to define which tiles connect based on neighboring tiles.

Step 4: Set Up the Autotile Bitmask

• Create a bitmask for each tile type:
  • Use the 2x2 grid to represent neighboring tiles (0 for empty, 1 for filled).
  • Configure the bitmask for each relevant tile based on its position in relation to others.
• Test your bitmask settings by painting tiles in the TileMap.

Step 5: Test Your Auto Tiling

• Go back to your main scene and use the TileMap tool to paint tiles.
• Click and drag to place tiles, observing how the auto tiling system automatically adjusts the tiles based on their neighbors.
• Make any necessary adjustments to the tiles or bitmask settings for optimal results.

Conclusion

You have successfully implemented auto tiling in Godot! This technique will streamline your level design and enhance your game's visual appeal. For further learning, consider exploring more features within the TileMap node or diving deeper into Godot's documentation to master game development. Happy designing!
