raylib
About
This skill helps developers leverage raylib's existing API to avoid reinventing solutions for graphics, input, or audio. It directs you to consult the official cheatsheet to find built-in functions before writing custom code. Use it to quickly check for available utilities in modules like shapes, textures, and audio.
Documentation
raylib Development
Check raylib's built-in functions before writing custom implementations.
Cheatsheet First
Reference: https://www.raylib.com/cheatsheet/cheatsheet.html
Before implementing any rendering, input, or audio feature:
- Identify the module (shapes, textures, text, models, shaders, audio)
- Scan that module's functions in the cheatsheet
- Only write custom code if no raylib function exists
Use WebFetch to retrieve and search the cheatsheet when uncertain.
Module Categories
| Module | Covers | Common Functions |
|---|---|---|
| rcore | Window, input, timing | GetFrameTime, IsKeyPressed, GetMousePosition |
| rshapes | 2D primitives | DrawLineEx, DrawRectangleRounded, DrawCircleSector |
| rtextures | Images, textures | DrawTexturePro, LoadRenderTexture, BeginTextureMode |
| rtext | Font rendering | DrawTextEx, MeasureTextEx |
| rmodels | 3D geometry | DrawMesh, LoadModel |
| raudio | Sound, music | LoadSound, PlaySound, SetSoundVolume |
| rlgl | Low-level OpenGL | Use only when raylib lacks the feature |
Before You Implement
Check these functions first for common tasks:
| Task | Check First |
|---|---|
| Thick lines | DrawLineEx(start, end, thickness, color) |
| Rounded rectangles | DrawRectangleRounded, DrawRectangleRoundedLines |
| Rotated/scaled sprites | DrawTexturePro(texture, source, dest, origin, rotation, tint) |
| Bezier curves | DrawLineBezier, DrawLineBezierQuad, DrawLineBezierCubic |
| Render to texture | LoadRenderTexture, BeginTextureMode, EndTextureMode |
| Screen capture | TakeScreenshot, LoadImageFromScreen |
| Shader uniforms | GetShaderLocation, SetShaderValue |
| Delta time | GetFrameTime() returns seconds since last frame |
Naming Conventions
raylib uses consistent verb prefixes:
Load*/Unload*— Resource lifecycleBegin*/End*— Scoped state (drawing, shader, texture mode)Draw*— Immediate renderingGet*/Set*— Property accessIs*— Boolean queries (IsKeyPressed,IsWindowResized)Check*— Collision detection
rlgl: Last Resort
rlgl exposes raw OpenGL. Use only when:
- raylib provides no built-in function
- Performance requires batched custom geometry
- Custom vertex attributes needed
For simple shapes, rshapes functions outperform hand-rolled rlgl.
Verification
When implementing graphics features, verify:
- Searched cheatsheet for existing function
- Checked
rshapesbeforerlgl - Used
DrawTextureProfor any sprite transforms - Paired all
