# Spurdoverse

- [Building a Full ESP](https://docs.spurdoverse.app/learn/building-esp.md): Step-by-step tutorial: build a polished ESP overlay with bounding boxes, health bars, name tags, and visibility checks.
- [Globals](https://docs.spurdoverse.app/api/globals.md): Timers, console output, event system, and the script object - available everywhere without imports.
- [Manifest & Permissions](https://docs.spurdoverse.app/api/manifest.md): manifest.json - how the loader finds your script and what it is allowed to touch.
- [Web APIs](https://docs.spurdoverse.app/api/web.md): The browser-standard globals available to scripts - and the ones that are not.
- [Networking](https://docs.spurdoverse.app/api/networking.md): HTTP and realtime sockets from a script - fetch, WebSocket, EventSource, XMLHttpRequest.
- [WebAssembly](https://docs.spurdoverse.app/api/wasm.md): Run WebAssembly modules inside scripts with full WASI Preview 1 support.
- [Math](https://docs.spurdoverse.app/api/math.md): Angle math, screen projection, and interpolation - built into the global Math object.
- [Render](https://docs.spurdoverse.app/api/render.md): Draw lines, shapes, text, and images on the screen overlay.
- [ESP](https://docs.spurdoverse.app/api/esp.md): Declarative per-entity overlays — register text, bars, and icons that the user lays out in the builder menu.
- [UI](https://docs.spurdoverse.app/api/ui.md): Declarative settings window — declare controls once, and the menu builds, persists, and binds them for you.
- [Game](https://docs.spurdoverse.app/api/game.md): Per-frame timestamps, tick counters, map info, and frame timing - engine state updated every tick.
- [FFI](https://docs.spurdoverse.app/api/ffi.md): Call native libraries, define C structs, and bridge JavaScript to any DLL or shared object.
- [FileSystem](https://docs.spurdoverse.app/api/fs.md): Read, write, and manage files inside a sandboxed data directory.
- [Memory](https://docs.spurdoverse.app/api/memory.md): Construct pointers, resolve loaded modules, and scan memory for byte patterns.
- [Entities](https://docs.spurdoverse.app/api/entities.md): Query, iterate, and read schema fields from any game entity - players, weapons, projectiles, and everything else.
- [Input](https://docs.spurdoverse.app/api/input.md): Simulate keyboard and mouse input, and read game input state.
- [Convars](https://docs.spurdoverse.app/api/convars.md): Read console variable values from the engine.
- [Trace](https://docs.spurdoverse.app/api/trace.md): Cast rays, boxes, spheres, and capsules through the game world - hit detection, visibility checks, overlap queries, and surface info.
- [localStorage](https://docs.spurdoverse.app/api/localStorage.md): Persistent key-value storage that survives script reloads and restarts - the familiar browser API, but better.
- [Vector](https://docs.spurdoverse.app/api/types/vector.md): 3D vector for positions, velocities, directions - the most used type in the engine.
- [Vector2](https://docs.spurdoverse.app/api/types/vector2.md): 2D vector for screen coordinates, UI layout, and planar math.
- [QAngle](https://docs.spurdoverse.app/api/types/qangle.md): Euler angles for view direction, aim, and rotation - pitch, yaw, roll in degrees.
- [Quaternion](https://docs.spurdoverse.app/api/types/quaternion.md): Rotations as unit quaternions - bone orientation, hitbox transforms, and gimbal-lock-free composition.
- [Color](https://docs.spurdoverse.app/api/types/color.md): RGBA color type with HSV/HSL conversion, blending, and brightness control.
- [Texture](https://docs.spurdoverse.app/api/types/texture.md): Load images from disk or memory for drawing on the overlay.
- [Pointer](https://docs.spurdoverse.app/api/types/pointer.md): A typed wrapper around a memory address with arithmetic, dereference, and structured read operations.
