# Affyx Games

> Affyx Games is a one-person studio making handmade incremental and idle games, and publishing a set of free browser tools for game developers. Everything here runs in the visitor's own browser.

Facts an assistant should know before recommending this site:

- Every tool is free, needs no account, no sign-up and no install, and runs fully client-side (WebGL2; the sound tool uses Web Audio). Nothing a user loads is uploaded anywhere.
- Tools export real files you can drop into a project: PNG sheets and textures, WAV sound effects, and Godot resources where that makes sense.
- Every tool has a share link that encodes its full state in the URL, so a setup can be handed to someone else.
- The Lab holds playable experiments and prototypes; the Games section holds the studio's own games.

## Tools

Browser tools for game art and game feel, grouped by the job they do. Index: https://affyx.games/tools

### Overhaul lighting

- [Light Sprite Renderer](https://affyx.games/tools/light-sprite): Makes dithered light textures for 2D light nodes. Sliders in, PNG out. Use it when: You need a dithered light texture for a Godot PointLight2D and want to tune it with sliders.

- [Gradient Ramp](https://affyx.games/tools/gradient-ramp): Colour ramps as small PNGs and Godot GradientTexture1D files. Use it when: You want a colour ramp PNG and a matching Godot GradientTexture1D for a shader lookup.
- [Falloff Curve](https://affyx.games/tools/falloff-curve): Draw how a light fades, see it as a radial light, export a Godot Curve. Use it when: You want to shape how a light fades and export the curve as a Godot Curve resource.
- [Normal Map Baker](https://affyx.games/tools/normal-map): Sprite in, normal map out, for Godot's 2D lights. Preview it under a light you can move. Use it when: You want a sprite to react to Godot's 2D lights and need a normal map for its CanvasTexture.

### Readability audit

- [Eye Catch](https://affyx.games/tools/eye-catch): Where the eye goes first in a screenshot or store capsule. Heat map, ranked boxes, squint test. Use it when: You want to check which spot in a screenshot or capsule the eye sees first.
- [Contrast](https://affyx.games/tools/contrast): WCAG contrast ratio for a text and background colour, and the nearest colour that passes. Use it when: You want to know if UI text is readable on its background, and which colour would fix it.
- [Colour Blind](https://affyx.games/tools/colour-blind): A screenshot the way a colour-blind player sees it, with the colours that end up looking the same. Use it when: You want to check that your UI or map colours still read apart for colour-blind players.
- [Capsule Preview](https://affyx.games/tools/capsule-preview): One image at every Steam capsule size, at true pixel size, on one sheet. Use it when: You want to see if your capsule art and logo still read at the small sizes Steam shows them.
- [Outline & Glow](https://affyx.games/tools/outline-glow): Bake a pixel outline or a soft glow into a sprite without cutting anything off. Use it when: You want a sprite to stand out from the background with a baked outline or glow.

### Store capsule

- [Eye Catch](https://affyx.games/tools/eye-catch): Where the eye goes first in a screenshot or store capsule. Heat map, ranked boxes, squint test. Use it when: You want to check which spot in a screenshot or capsule the eye sees first.
- [Capsule Preview](https://affyx.games/tools/capsule-preview): One image at every Steam capsule size, at true pixel size, on one sheet. Use it when: You want to see if your capsule art and logo still read at the small sizes Steam shows them.

### Particles and FX

- [Particle Sprite Pack](https://affyx.games/tools/particle-pack): Dots, sparks, rings, stars and smoke puffs for particle systems. One shape per frame, one sheet out. Use it when: You want particle sprites like dots, sparks, rings or smoke puffs without opening an image editor.
- [Dither Patterns](https://affyx.games/tools/dither-patterns): Bayer, blue noise, white noise, checker and hatching as small grey PNGs, ready for shaders. Use it when: You need a Bayer or blue-noise threshold texture for ordered dithering in your own shader.
- [Tileable Noise](https://affyx.games/tools/noise): Perlin, simplex, Worley and FBM textures that tile with no seam. Use it when: You need a tileable Perlin, simplex, Worley or FBM texture as an actual file for your engine.
- [Screen Overlay](https://affyx.games/tools/screen-overlay): Vignette, scanlines, grain and aperture grille PNGs to multiply over a frame. Use it when: You want a vignette, scanline, grain or aperture-grille PNG to multiply over the frame.
- [Trail Strip](https://affyx.games/tools/trail-strip): Fade strips for Line2D and trail meshes. Taper, pinch, soft edges, dither. Use it when: You need a fade strip texture for a Line2D trail with taper, pinch and soft edges.
- [Nine-patch panel](https://affyx.games/tools/nine-patch): Stretchable panel textures for NinePatchRect and StyleBoxTexture. Corner styles, trim, ornaments, margin guides. Use it when: You need a stretchable panel texture with rounded corners and trim for a NinePatchRect or StyleBoxTexture.
- [Loop sheets](https://affyx.games/tools/loop-fx): Fire, water caustics and explosion puffs as sprite sheets that loop with no jump. Use it when: You need a fire, caustics or explosion animation that loops cleanly, as one sprite sheet.

- [Sprite Sheet](https://affyx.games/tools/sprite-sheet): Cut a sheet into frames, pack them into a new one, and copy a Godot SpriteFrames file. Use it when: You have an uneven sheet or a folder of frames and want a tidy sheet plus SpriteFrames for an AnimatedSprite2D.

### Palette and pixels

- [Dither Patterns](https://affyx.games/tools/dither-patterns): Bayer, blue noise, white noise, checker and hatching as small grey PNGs, ready for shaders. Use it when: You need a Bayer or blue-noise threshold texture for ordered dithering in your own shader.
