How to import AI sprite sheets into Unity, Godot, GameMaker, RPG Maker and Phaser

To import an AI sprite sheet into a game engine, download it as a PNG grid, a set of frames or a sheet plus JSON, then tell the engine how the grid is laid out. Ludo.ai's Sprite Generator lays every sheet out as a square grid (36 frames is 6 columns by 6 rows) read left to right, top to bottom, and writes the frame count, rows and columns into the file name. Unity and Godot slice the PNG by column and row count, GameMaker imports the frames or a strip, Phaser loads the TexturePacker-format JSON as an atlas, and RPG Maker needs the frames arranged into its own character sheet layout.

1. 1Choose the export in Ludo.ai

   Open the result's menu in the Sprite Generator. Download Sprite Sheet gives the PNG grid, for Unity, Godot and GameMaker. Download All Frames gives a zip of PNGs named frame_000.png, frame_001.png and so on, for GameMaker and RPG Maker. Download Sheet + JSON gives a zip with the PNG and a TexturePacker-format JSON, for Phaser. For several animations of one character, use Export > Animation Pack so every sheet shares one frame size and ground line, and choose Pixel Art there for nearest-neighbor scaling on pixel art.

2. 2Unity: slice the sheet in the Sprite Editor

   Drag the PNG into your Assets folder. In the Inspector set Texture Type to Sprite (2D and UI) and Sprite Mode to Multiple; for pixel art, set Filter Mode to Point (no filter). Click Open Sprite Editor, open Slice, set Type to Grid By Cell Count and enter the column and row counts from the file name (6 and 6 for a 36 frame sheet). Set the Pivot, click Slice, then Apply. Turn on Keep Empty Rects if a frame is fully transparent, so the frame order stays intact. See Unity's Sprite Editor guide and sprite import settings.

3. 3Godot: build SpriteFrames from the sheet

   Add an AnimatedSprite2D node, give it a new SpriteFrames resource, and in the SpriteFrames panel choose "Add frames from a Sprite Sheet". Select the PNG, set Horizontal and Vertical to the column and row counts, select the frames and add them. Set the animation speed to the frame count divided by the duration in seconds (36 frames over 3 seconds is 12 FPS) and turn on looping if needed. As an alternative, set Hframes and Vframes on a Sprite2D and animate its frame property with an AnimationPlayer. For pixel art, set the node's Texture Filter to Nearest, or set the project default in rendering/textures/canvas_textures/default_texture_filter. See Godot's 2D sprite animation tutorial and CanvasItem reference.

4. 4GameMaker: import frames or a strip

   Create a Sprite, click Import and select all the PNGs from Download All Frames; selecting multiple files adds each one to the sprite as a sub-image. To use the grid sheet instead, use the Inspector's Import Strip option, which opens the Convert to Frames window where you set the number of frames, the frame width and height, and any offsets. Then set the origin, the point placed at the instance's position, and the frame speed in frames per second. For pixel art, turn off "Interpolate colours between pixels" in the Game Options for your target platform. See GameMaker's Sprite Editor, Image Editor and Windows Game Options pages.

5. 5RPG Maker: arrange frames into a character sheet

   RPG Maker MZ reads map characters as PNG files from img/characters. Per its asset standards, each character has 3 patterns for each of 4 directions (up, down, left, right), and the pattern size comes from the file: 1/12 of its width and 1/8 of its height, which is 48x48 pixels at MZ's default tile size. A standard file holds 8 characters in 2 rows of 4, and a "$" at the start of the file name makes the file a single character, 3 patterns across and 4 directions down. The Sprite Generator does not export this layout, so assemble it: in Transfer Motion, generate the same walk once per direction with identical settings, use Download All Frames for each, pick 3 frames per direction, scale them to your character size and arrange them in an image editor, following the direction order of a character sheet already in your project. Walk presets are humanoid-only; for other characters, use a reference video in Transfer Motion or describe the motion in Animate.

6. 6Phaser: load the atlas or a fixed-size sheet

   Unzip Download Sheet + JSON and load both files with this.load.atlas('hero', 'hero.png', 'hero.json'). Phaser reads JSON Hash and JSON Array atlases; the export is a hash with frames named frame_000, frame_001 and so on, so this.anims.generateFrameNames('hero', { prefix: 'frame_', start: 0, end: 35, zeroPad: 3 }) returns a 36 frame sequence to pass to this.anims.create with a frameRate. Without the JSON, load the plain sheet with this.load.spritesheet('hero', 'hero.png', { frameWidth: 128, frameHeight: 128 }) using the cell size, and reference frames by number. For pixel art, set pixelArt: true in the game config. See Phaser's LoaderPlugin, animations and game config docs.
