Like in reislust, which means wanderlust in dutch. Originally implemented in C and pure OpenGL, now in Java with LWJGL, specifically GLFW and JOML. All implementations are kept as decoupled and replaceable as possible.
The bestselling video game of all time was a voxel-based exploration game that started as a java proof of concept. Many people had a great time playing it, but the amount of time and effort put into the game by its community far outmatched that of its original developers, who did not realize its true potential: the mod community. More and more AAA game titles are released unfinished because they do not see the potential in mod community oriented development; instead of trying and failing to release a full game, release a proof of concept, if it is well received immediately complete a mod API, then implement the entire game with it. The mod community will take care of the unfinished parts for free.
Create a game client and server, create a voxel and physics engine, finish a mod API, then implement an exploration game with that API. Every part of the engine may be accessible to the API, completely decoupled, and compatible with other client and server implementations, in order to take full advantage of content created by the mod community. Release it for free.
- Runtime single player works, no networking or local multiplayer yet.
- Voxel rendering works, but is not performant.
- Physics enables player movement, floor collision, and friction.
- World and player completed for engine testing, no gameplay yet.
The documentation for the client, server, and engine should be simple enough to fit in this readme. The API and game will be separate projects with much longer documentation. Here are descriptions of the classes and methods in the client:
server/client/ClientLWJGL.java
A client implementation in Java using GLFW with LWJGL. It takes input from a keyboard and mouse, and displays output with immediate mode OpenGL.
Starts a client in a new thread, reads GLFW events, and centers the cursor.
Creates a new keyboard and mouse controller, a new GLFW window, and starts as a server.
Extends org.reis.server using GLFW.
Frees memory allocated by GLFW.
server/client/ImmediateModeRenderer.java
Renders org.reis.game.Player, org.reis.game.World, and String debug text.
If given no input, clear the output buffer.
If given an org.reis.game.Player input, translate to the position of that player, and rotate to the orientation of that player.
If given an org.reis.game.World input, render the blocks of that world.
If given a String input, print it as a char buffer for debugging.
server/client/KeyboardMouseController.java
Read the keyboard and mouse with GLFW callbacks, and produce acceleration and inertia vectors.
Methods called by the anonymous methods used as GLFW callbacks, called by glfwWaitEvents in ClientLWJGL.main
server/Server.java
An abstract class that stores and updates the states of players and worlds.
Loop that checks if the server has quit, reads input, updates the server based on the amount of time elapsed since the last update, and writes output.
Updates all worlds by an interval of time.
Abstract methods used in the loop.
