Glide Runner — 2D Platformer + Level Editor

Glide Runner is a fast, 2D precision platformer built in C with raylib. It features tight, grid-aligned movement and a built‑in level editor.

Game Description

• Fast, 2D precision platformer about flow and timing.
• Glide through tight spaces and thread around laser traps.
• Solid blocks shape each arena; route‑finding matters.
• Reach the glowing exit to clear each level; instant restarts.
• Built‑in level editor to design, save, and play your own challenges.

Prerequisites

• A C toolchain: clang or gcc, and make
• Platform SDK bits that raylib needs (e.g., Xcode Command Line Tools on macOS; X11 dev packages on Linux)

raylib is vendored as a Git submodule under raylib and is built automatically by the Makefile.

Submodule

After cloning this repo, initialize submodules once:

• git submodule update --init --recursive

Build & Run

• Build: make (first run builds vendored raylib for desktop)
• Run: make start (runs ./main)
• Clean: make clean
• Format sources: make format

The build outputs a binary named main (ignored by Git).

Web (WASM)

This project can build to WebAssembly using Emscripten. The Makefile uses the vendored raylib and will build it for the web target automatically.

Prerequisites:

• Emscripten SDK installed and activated (emcc on your PATH)

Build and serve:

• Build: make web (builds raylib for PLATFORM_WEB and outputs web/index.html + .wasm/.js)
• Serve: from repo root python3 -m http.server then open http://localhost:8000/web/
• Alternatively: emrun web/index.html

Notes:

• The web build defines PLATFORM_WEB and packages assets/, levels/, and config/ for read-only access at runtime.
• Building for web overwrites the raylib static library in raylib/src. Running make again will rebuild the desktop library automatically.
• You can override RAYLIB_INC/RAYLIB_WEB_LIB_DIR to point at a different raylib build if desired; defaults point to raylib/src.

Default Controls

• Gameplay: Move = A/D or Left/Right; Jump = Space/W/Up; Back = Esc.
• Menu: Navigate = W/S or Up/Down; Select = Enter/Space; Back = Esc; Mouse can click items.
• Editor: Move cursor = Mouse or Arrow keys; Place/use tool = Space or Left click; Tools = 1–5, Tab cycles; Save/Back = Esc; Test play = Enter/Space.

Level Editor

• Open via “Edit existing level” or “Create new level” from the main menu
• Move cursor: Mouse or Arrow keys
• Place/use tool: Space or Left Click
• Switch tools: Tab cycles, or press 1–5 directly
  • 1: Player spawn
  • 2: Add block
  • 3: Remove block
  • 4: Level exit
  • 5: Laser trap
• Test play: Enter (saves, then launches a test run)
• Exit editor: Esc (saves and returns to menu)

Levels are stored under levels/ as .lvl files. “Create new level” will pick the next available index automatically.

Troubleshooting

• Link/include errors for raylib: ensure the headers and libs are installed and the Makefile CFLAGS/LIBS paths match your system. On Linux distros that install system-wide, you can often remove the explicit -I/-L and just keep -lraylib, or switch to pkg-config flags.
• Audio issues on first run: the game initializes the audio device; make sure your environment permits audio output.

Project Layout

• Source: *.c, *.h
• Assets: assets/
• Levels: levels/*.lvl
• Configurable inputs: config/input.cfg (optional; falls back to sensible defaults)

Enjoy hacking and making levels!
