Demolition Synergy showing multiplayer setup.

Verbose Description

Robust (yet still uncomplete) Game Engine writen in Java. Free & Open-Source. Project started back in a day on October 15, 2017. And possible earlier.

Key features:

• Dynamic lights.
• Water Reflections.
• Shadow Effects.
• Voxel based. Minecraft-like. Not a Minecraft-clone.
• Varying update with one tick per update or two ticks per update. (inspired by classic Doom port Zandronum)

Unique features:

• Console (similar to Quake III Arena) with ingame commands.
• Ambient soundtracks (credits to Erokia).
• Random level building & manual level building via Editor.
• Tweaked and unique renderer. Instanced rendering.
• Highly modular and support visual & GLSL modifications.
• Editor, Single player & Multiplayer as different modes.
• Player Guid oriented protocol where Guid is based on hardware properties.

How To Build

Build was coded in Apache NetBeans IDE 16. Requires Java JDK 11 (or later). In order to build the project you are gonna need NetBeans IDE 16 (or later) and following libraries:

1. LWJGL 3.3.3 with JOML 1.10.5 (not installed, follow the steps below),
2. Jorbis OGG Decoder (for OGG audio files) (installed),
3. GapList & BigList (for Block lists) (installed),
4. Apache logger (Log4J) with dependecies (installed),
5. Google Gson (installed),
6. Apache MINA, for networking (installed).

Download latest library LWJGL (3.3.3 at this time) from: https://www.lwjgl.org/customize (this project is using Minimal OpenGL)

Put MoveAllFiles.bat inside the directory with downloaded & extracted zip content. Run MoveAllFiles.bat and wait brief amount of time (less than 3 seconds) to sort out the files under directories. Put rest unsorted files into classpath directory.

In Apache NetBeans IDE 16 (or later) create new library by specifying classpath, sources & javadocs in that order.

Add library to the project.

Done.

• audio => Music/soundFX effects.
• cache => Contains chunk ssd/hdd disk caching.
• chunk => Series of blocks for instanced rendering.
• core => Camera, frame buffer, water reflection, window class etc.
• critter => Observer (camera interface), player & npc.
• intrface => Ingame interface & 2d rendering components.
• level => Level container, level actors, level editor, random level generator.
• light => Light projection on the screen, light source(s).
• location => Block location matrix 384x384x384 on X,Z & Y axis.
• main => Main inependable classes, Game (client with main loop), GameRenderer (separate thread) & GameObject links them together. GameServer is relevant class for hosting a server on the PC. UDP (User datagram) protocol is being used with 13667-13668 ports.
• models => 3d looking models and their part(s) - vertex, mesh, material.
• net => DSObject to be send over network - Request and Response. Stuff for multiplayer.
• resources => Ingame block (models) cube.txt (deprecated) & cubex.txt.
• shaders => Shader - Vertex & Fragment GLSL, Shader Program - binds them together.
• texture => Ingame textures & texture store hashmap.
• util => Various utils & auxillary methods including logging, math, image & model utils.
• weapons => Planned First person shooter weapons & gameplay (TODO).

Game Assets

Project assets come from various sources.
