2.5D (pseudo-3D) game engine

2.5D retro game engine. Old school software 3D rendering.

Builds and runs on Windows, Linux and WebAssembly.

TRY IT HERE: http://dungeoncrawler.dx.am/ (Requires a browser with webassembly-support)

Features:

• Raytraced 3D rendering, similar to old games like Wolfenstein (raytracing on a 2D grid).
• Level scripts and script components, using ChaiScript.
• WebAssembly support (can run in browser).

How to build

WINDOWS

• Open CMake GUI (can download from here: https://cmake.org/download/)
• In "Where is the srouce code", browse to the repository folder containing CMakeLists.txt
• In "Where to build the binaries", chose any folder (i.e. subfolder "/build")
• Make sure the directory can be written to (to prevent MSB3073 error)
• Configure
• Build
• Open Visual Studio project
• Build and run the "Game" project (IN RELEASE CONFIGURATION - Debug will be very slow!)

LINUX

• Open the terminal and change directory ("cd" command) to the root folder of the repository.
• Run aptget.sh (or manually do apt-get on the dependencies). Note: if you get "permission denied", execute "chmod +x aptget.sh" in the terminal first.
• Run CMake: cmake .
• Build the "Game" project (or make your own project based on that): make Game
• Go to "projects/samples" and copy the "resources" folder of the samle you want to use into the same folder as the build executable.
• Run the executable: ./Game

WEB ASSEMBLY

• Make sure you have Emscripten installed (https://developer.mozilla.org/en-US/docs/WebAssembly/C_to_wasm)
• Also make sure you have newest version of Python 2.x installed
• Run emcc_generate.py
• Run emcc_build.bat
• Find your webpage in the "webbuild" sub folder
