A 3D game engine for making retro FPS games.
This is a 3D game engine designed specifically to replicate the retro look of old classic shooters of the 90's, commonly called 2.5D shooters. Level geometry consists of 2D polygons projected into 3D space, and objects in the world are billboarded sprites.
This engine is not derived from id Tech 1, BUILD or Marathon's engine. It does not play any classic 90's shooter out of the box. The renderer is GPU-accelerated; there are no plans for a traditional software renderer.
This engine consists of a client, server and editor.
$ npm run build-client
$ npm run build-server
$ npm run build-editor
If you are building the client, you must also build a files manifest so the client knows what files it has access to.
$ npm run build-files
To run the client or editor, serve the /public directory using your webserver of choice, or if you want to get up and running quickly, you can use the built-in webserver by running the webserver task:
npm run webserver
You can run the game server like this:
$ npm run server
