amilich/isometric-city

Overview

This skill generates consistent isometric sprite sheets for an isometric city builder using the GenerateImage tool. It enforces a strict tile grid, red background, hyper-realistic style, and no shadows to ensure assets import cleanly and match the engine's projection rules. The output is a full 2048x2048 asset sheet with predictable row/column mapping.

How this skill works

The skill builds a standardized prompt and calls GenerateImage to produce a 6x5 grid (30 cells) on a solid red (#FF0000) background. Each row is one asset rendered in four isometric orientations (NW, NE, SE, SW) plus a type-specific special view in column five. It applies asset-type constraints (for example: no landing gear for airplanes in flying views, visible wheels for vehicles, no water or wake for boats) and ensures all assets are hyper-realistic and centered in each cell.

When to use it

• Creating new vehicle, aircraft, boat, helicopter, or train sprites for the game
• Generating building or nature asset sheets with consistent isometric projections
• Replacing or updating existing sprite sheets to a standardized format
• Preparing assets for automated import and mapping in the renderer
• Producing multiple variants of the same asset type for size/category organization

Best practices

• Always specify asset type and per-row category descriptions (e.g., sedans, SUVs, trucks).
• Include explicit constraints in the prompt: "NO SHADOWS", "same size for all assets", "centered in each cell".
• Use the provided special-view rules for column five based on asset type (e.g., gears down for airplanes).
• Keep lighting consistent across rows and avoid motion effects (no motion blur, no contrails).
• Validate generated sheet at 2048x2048 and then save with a descriptive filename before adding to the project.

Example use cases

• Generate a 2048x2048 sheet of six commercial and private airplanes, rows 1–3 commercial, rows 4–6 private; column five = gears down head-first view.
• Create a vehicles sheet: rows 1–2 sedans, 3–4 SUVs, 5–6 trucks; column five = 3/4 front isometric view.
• Produce six boat sprites grouped small-to-large with column five docked/stationary overhead view, no water or wake.
• Make a buildings sheet where each row is a building variant with column five showing a front-street isometric detail view.
