How to make a tileset for a 2D game with AI

To make a tileset for a 2D game with AI, generate each tile as its own image in one art style and one perspective, keep the tiles on a transparent background, and assemble them into a tileset in your engine or map editor. In Ludo.ai's Sprite Generator, use the map tile type for floor, wall and terrain cells, and the horizontal or vertical tiling sprite types for pieces that must repeat, such as platforms or ropes. Each generation is a single tile image rather than a ready-made autotile or terrain set, so you add the terrain rules and collisions in Godot's TileSet editor or in Tiled.

1. 1List the tiles and the grid size

   Decide the cell size and perspective first, then list every tile the map needs. For automatic transitions (grass meeting dirt, walls meeting floor), include each edge and corner piece your editor's terrain mode expects, since every piece is a separate tile.

2. 2Pick the tile type

   Open the Sprite Generator on the New Sprite tab and choose the type in the picker next to the prompt: the map tile type (tile) for independent grid cells, the horizontal tiling sprite (sprite-tiling-horizontal) for platforms, bridges and fences, or the vertical tiling sprite (sprite-tiling-vertical) for ropes, chains, vines and ladders. All three are generated without a background.

3. 3Set the style, perspective and shape

   Open Filters and set the Art Style your game uses, the Perspective that matches your map (Top-Down, Isometric, High Angle or Side-Scroll), and an Aspect Ratio of Square for grid cells. Keep these settings the same for every tile in the set.

4. 4Describe one tile per prompt

   Describe the surface and material of a single cell, for example "mossy cobblestone floor" or "wooden plank bridge". Leave characters and props out of the prompt and place them as separate sprites on a layer above the tiles. Compare a few variations before you pick one.

5. 5Generate the rest of the set from one reference

   Once one tile looks right, open the Image Generator, switch the Generation Mode to Generate with Style, add that tile as the reference and pick the same tile type. Using one reference for every tile keeps colors, lighting and texture detail consistent across the set.

6. 6Check the seams

   Open a horizontal or vertical tiling sprite in the fullscreen viewer and use Scroll endlessly or Repeat side by side (Repeat stacked for vertical sprites) to see how the ends meet. Map tiles are independent cells with no seamless-edge guarantee and no repeat preview, so place a few side by side in your map editor and generate another variation if the edges clash.

7. 7Animate water, lava or torches (optional)

   On the Animate tab, add the tile as the starting frame, choose the same type, and describe the motion ("water ripples across the surface"). For tiling sprites, choose Forge or Forge Pixel as the Model, because the other models do not preserve the seam. Set Max Frames, Sprite Size and Loop Animation, then export the frames; the steps are the same as in how to turn an image into a sprite sheet.

8. 8Build the tileset in your engine

   Scale each tile to your cell size and import it. In Godot, add each image as an atlas in a TileSet (the atlas merging tool combines them into one), set up terrain sets for autotiling, and paint with a TileMapLayer. In Tiled, a Collection of Images tileset takes one file per tile (editing tilesets), and terrain sets handle the transitions.
