The "pixel art" isn't real pixel art — zoom in and it's a blurry mess of mixels. 2. Generated spritesheets bleed between frames the moment you slice them. 3. And the moment you put them in a game, the character drifts and bobs all over the screen. In this video I walk through my entire step-by-step process to take AI-generated sprites all the way from broken to **fully game-ready**. Real pixel art, no bleeding, no drift, dropped straight into a working Phaser game. If you've ever wanted to know how to create game assets that not only look good on the surface, but are also prepared in a way that you can actually integrate into a game — this video is for you. 🛠️ THE STACK • Image generation: GPT Image 2.0 (anchors + actions: idle, attack, hurt, jump, death) • Multi-model access: fal.ai (Nano Banana 2, GPT Image 2.0, and more) • Pixel snap: Sprite Fusion Pixel Snapper (open source) ported into a Codex / Claude Code agent skill • Frame curation + alignment: custom frame-picker + frame-aligner GUIs • Background removal: chroma-key + AI bg-removal • Game engine: Phaser + TypeScript 🚀 WHAT YOU'LL LEARN • Why most AI-generated "pixel art" isn't real pixel art (mixels vs pixels) • The 3 problems that break AI sprites in a real game: mixels, frame bleeding, frame drift • How to generate a 1024×1024 reference image with the right prompt discipline • How to pixel-snap a generated image into a true pixel-art anchor (and why you scale it back up) • How to generate the W-facing anchor from the snapped S — and why you snap it again • Pose-board geometry for animation generation: 2048×1536, 4×3, 512×512 cells • Frame recovery — extracting characters via chroma-key bounding boxes (NOT naive grid crops) • Frame curation — picking a clean N-frame cycle from a generated pose board • Per-frame pixel snap that stops mixel re-emergence in animation frames • Frame anchoring with onion-skinned manual alignment • Final normalisation + packing into a 1280×512 runtime spritesheet (256×256 cells) 🕒 TIMESTAMPS 00:00 Intro 01:24 This video's resources and more 02:31 Overview of what we're building 03:49 Pick any AI tool 05:36 Problem 1: Fake pixels or 'mixels' 05:59 Problem 2: Frame Bleeds 06:46 Problem 3: Frame Drifts 07:28 Step 1: Generate a reference image 08:59 Step 2: Pixel Snap to Anchor 14:09 Step 3: Generate West-facing anchor 15:52 Step 4: Pixel snap (again!) 16:52 Step 5: Generating animation spritesheets 20:34 Step 6: Recovering Frames 21:32 Step 7: Curating Frames 22:40 Step 8: Pixel Snap Each Frame 23:14 Step 9: Anchoring Frames 24:47 Step 10: Normalise and combine 27:35 Wrap up 🔗 LINKS • Sprite Fusion Pixel Snapper: https://github.com/SpriteFusion/Sprite-Fusion-Pixel-Snapper • Sprite Fusion (online tool): https://spritefusion.com/pixel-snapper • fal.ai: https://fal.ai • Phaser: https://phaser.io #vibegamedev #aigamedev #vibecoding #claudecode #codex #pixelart #pixelsnap #spritesheets #gptimage2 #falai #nanobanana #gamedev #indiedev #aiart #gameassets #gpt5 #gptimage2
