The image agents — prompt to PNG
Post 4 of 8 in the game-factory series. Icons are what people look at You can theme fonts, colors, win messages, and sound effects. Change all of it and the game still reads like the original with a skin on it. Swap the icons — the actual symbols spinning in the reels — and it reads like a different game. The casino template I built by hand uses cloud service logos. Replace those with golden…
Post 4 of 8 in the game-factory series reveals the importance of consistent icon design for game aesthetics. Icon agents, Image-Gen and Background-Gen, handle the visual layer. Image-Gen processes each symbol's prompt, generates PNGs at 256×256 resolution, and writes them to the app's public/images folder. Background-Gen creates a single background image.
The agents share architecture, failure modes, and lessons, with the only difference being the output count. The happy path involves decoding, resizing, and writing the image to disk. However, the real challenge lies in achieving uniformity across a set of generated icons. Stable Image Core returns independent results, leading to inconsistent art styles.
While prompt engineering and reducing symbol counts can help, they don't fully solve the problem. The inconsistency is particularly noticeable when the game looks like a themed game rather than an art-directed one. The developers discovered a post-deployment issue with the background image not appearing due to incorrect path referencing.
The fix involved a one-liner using JavaScript inline style with process.env.PUBLIC_URL. This story highlights the need to plan for consistency in generating related images and own the necessary post-processing in plain code.
