What is an AI game asset generator?

It draws the art a game needs from a written description: sprites, item icons, tiles, UI buttons and level art. In Batch Banana you draw a whole set on one sheet, and the Slice tool cuts it into one file per sprite for free. A Nano Banana 2.1 image costs 10 credits.

Blockout to art pass

Turn your blockout into level art

The top-down blockout supplies the layout and the mole supplies the style. The prompt assigns art to each blockout color, followed by a second pass for evening light. Drag to compare.

  • A generated top-down level blockout on a six by six grid: tan soil squares with dark brown tunnel stripes, three green circles for sprouts, two grey squares for rocks, a red circle for the player and a green grass border
    The blockout painted by AI as the finished level seen from above: terracotta tunnel tiles, rounded grey rocks and green sprouts where the blockout put them, the mole in its hat popping out of a burrow on the bottom row, a grass border with daisies

    Blockout to art pass

    The soil tiles, the rocks, the sprouts and the mole stay where the blockout put them. Some tunnel shapes changed inside their tiles, so check the layout before you build on it.

    The same level at dusk, edited by AI: blue-violet light over the board, a glowing lantern beside the mole warming the nearest tiles, small fireflies over the grass, every tile, rock and sprout in place

    Morning to evening

    The morning level becomes a dusk scene lit by the mole's lantern, with the layout unchanged.

Slice

Split your sprite sheet into separate files

BiRefNet removed the cream background first, for 2 credits, because the mole's cream muzzle matched it. Then Slice found the six poses by shape and put each on a canvas of the same size, so they line up when they play. Slicing is free.

Sprite sheet
A generated sprite sheet of the mole in six poses in three columns and two rows on plain cream: standing, digging, popping out of a soil hole, cheering, holding a carrot and asleep

Remove background with BiRefNet, then Slice: Shapes, Same size, transparent background.

Six files
Frame 1, the mole standing idle, cut from the pose sheet by Slice onto a transparent same-size canvas
Frame 2, the mole digging with both paws, cut from the pose sheet by Slice onto a transparent same-size canvas
Frame 3, the mole popping out of a soil hole, cut from the pose sheet by Slice onto a transparent same-size canvas
Frame 4, the mole cheering with both arms up, cut from the pose sheet by Slice onto a transparent same-size canvas
Frame 5, the mole holding a carrot, cut from the pose sheet by Slice onto a transparent same-size canvas
Frame 6, the mole asleep on its side, cut from the pose sheet by Slice onto a transparent same-size canvas

Game art and the prompts that made it

Every card is a real run: the prompt, the model and the credits for one image. Prompts that name Image 1 had an image attached.

A generated game character: a small round cocoa-brown mole with a cream muzzle, a pink nose and pink paws, in a butter-yellow bucket hat with a green band, waving, in soft matte 3D on plain cream

The main character of a cozy mobile puzzle game: a small round mole gardener. A plump pear-shaped body in soft cocoa-brown velvet, a pale cream muzzle, a round pink nose, tiny happy crescent eyes, small rounded pink paws and short pink feet, and a butter-yellow bucket hat with a thin leaf-green band. Standing, turned three quarters to the left, waving one paw. Full body, centered, filling about two thirds of the frame, on a flat plain cream background with one soft contact shadow. Soft matte toy-like 3D, like painted vinyl and smooth clay, a smooth satin surface, rounded chunky shapes, a clean readable silhouette, warm soft key light from the top left, gentle ambient occlusion, no outlines, no glow. No text.

The blockout painted by AI as the finished level seen from above: terracotta tunnel tiles, rounded grey rocks and green sprouts where the blockout put them, the mole in its hat popping out of a burrow on the bottom row, a grass border with daisies

Image 1 is a top-down level blockout for a cozy mobile puzzle game. Image 2 is the game's mole character. Paint the blockout as the finished level, seen from directly above, in the soft matte toy-like 3D style of Image 2: the tan squares become chunky terracotta soil tiles, the dark brown stripes and curves become smooth tunnel channels carved into them, the green circles become small green sprouts, the grey squares become rounded grey rocks, the red circle becomes the mole from Image 2 popping out of a burrow, and the light green border becomes soft grass with a few daisies. Keep every tile, tunnel, sprout, rock and the mole exactly where the blockout puts them. Warm soft morning light from the top left. No grid lines, no UI, no text.

The same level at dusk, edited by AI: blue-violet light over the board, a glowing lantern beside the mole warming the nearest tiles, small fireflies over the grass, every tile, rock and sprout in place

Image 1 is a finished level of a cozy mobile puzzle game. Make the evening version: every tile, tunnel, sprout, rock and the mole stay in the same places and the same style. The light is now a warm dusk: a deep blue-violet evening over the garden, a small glowing lantern beside the mole lighting the nearest tiles in warm amber, and a few soft yellow fireflies over the grass. Keep it cozy and readable. No UI, no text.

A generated tile set of nine chunky terracotta soil tiles in a three by three grid on cream: straight, corner, T and cross tunnels, a dead-end burrow, and tiles with a grey rock, a sprout, a carrot top and grass

Image 1 shows the art style of a cozy mobile puzzle game where you rotate tunnel tiles in a vegetable patch so a mole can reach every sprout. A tile set of 9 square game tiles in the same soft 3D style and palette, in a grid of 3 by 3, the same size, with a wide even gap around each, on a flat plain cream background. Each tile is a chunky rounded square block of terracotta soil seen from above at a slight angle, with a smooth dark cocoa tunnel channel carved into its top face: a straight tunnel, a corner, a T junction, a crossing, a dead-end burrow hole, then a tile with a rounded grey rock, a tile with a small green sprout, a tile with a carrot top poking out, and a plain tile topped with soft grass. Warm soft light from the top left, no outlines, no glow. Do not draw the mole. No labels, no text.

A generated sheet of nine rounded-square game buttons with raised cream glyphs: play and pause in yellow, restart, hint and home in green, settings and sound in brown, a star and a heart in coral

Image 1 shows the art style of a cozy mobile puzzle game. A sheet of 9 game UI buttons in the same soft 3D style and palette, in a grid of 3 by 3, each a chunky rounded-square button with a raised cream glyph, the same size, with a wide even gap around each, on a flat plain cream background: play and pause in butter yellow; restart arrow, hint lightbulb and home in leaf green; settings gear and sound speaker in cocoa brown; a star and a heart in coral. Simple bold glyphs readable at small size, warm soft light from the top left, no outlines, no glow. Do not draw the mole. No letters, no numbers, no text.

A generated sprite sheet of the mole in six poses in three columns and two rows on plain cream: standing, digging, popping out of a soil hole, cheering, holding a carrot and asleep

Image 1 is the mole character of a cozy mobile puzzle game. Draw the same mole, identical in design, colors, proportions and hat, on a sprite sheet of 3 columns by 2 rows, read left to right, top row first: standing idle, digging with both paws, popping up out of a small soil hole, cheering with both arms up, holding a carrot, asleep curled up. Every pose the same size and facing right, one per cell, with a wide even gap around each, on a flat plain cream background, no shadows under the poses. No grid lines, no labels. Soft matte toy-like 3D, rounded chunky shapes, warm soft light from the top left, no outlines, no glow. No text.

A generated tall phone level screen: a board of terracotta tunnel tiles with rocks and sprouts inside a low wooden fence, cabbage and carrot beds around it, the mole peeking from a burrow below, calm grass at the top and bottom

Image 1 is the mole character of a cozy mobile puzzle game. A phone level screen for the game with no interface: a small vegetable patch seen from above at a gentle three-quarter angle, built as a soft 3D diorama. In the middle, a board of 5 by 6 chunky terracotta soil tiles with smooth dark tunnel channels, some joined and some not; small green sprouts poke up from three tiles; rounded grey rocks sit on two. The mole from Image 1, identical in design, peeks out of a burrow on the bottom row. Around the board: a low wooden fence, cabbages and carrot tops in neat beds, a few daisies. The top fifth and the bottom fifth of the screen are calm grass with nothing in them, for the score and the buttons. Warm soft morning light from the top left. Soft matte toy-like 3D, rounded chunky shapes, no outlines, no glow. No text, no numbers.

How it works

How to create and export game assets

  1. Draw the set on one sheet

    Give the grid as rows and columns, one sprite per cell at the same size, with a wide gap around each. For an animation, name each row's action and frame count.

  2. Keep the background flat

    Use one plain color the art does not use, and no shadow or glow under a sprite. A busy background has to be removed before slicing, which costs credits.

  3. Slice it into files

    Slice finds each sprite by shape or by grid, up to 256 from one sheet, for free. Trim crops each to its own edges; Same size puts animation frames on one canvas.

One run on Nano Banana 2.1: 4 images at 1:1, 40 credits.

Create with the agent

The agent uses the Sprite sheets skill to plan sprite sheets, tile sets and UI kits for slicing.
