Free simulation games online software for linux

Stamits Online Poker project is a simple OpenGL poker game that can be played online with another person.

Compilation:

Make sure you have the GNU C and C++ compilers.

Get MOGUL, the Minimal OpenGL Utility Library, compile and install it (or use a compiled binary version, if there is one available). Instructions should be included.

Open `Makefile and uncomment the lines below the label `Unix configuration.

Say `make. The result should be an executable named `sopoker in the current working directory.

Particle Simulation project is a simulation of spraying up to 60k particles in realtime.
Particle Simulation is a playful simulation game which allows you to spray particles into the "air". The number of simulated particles is only limited by the speed of your computer.
The particles dont interact with each other, but will bounce back from the ground and accelerate depending on a gravity constant.
This constant can be changed (along with a number of other parameters) in the source code or via commandline parameters.
Enhancements:
- Colors were adjusted and a new animation mode was introduced.
- Segmentation fault was fixed.

Sloth Online RPG is aJava Online RPG with Real-Time Action and rich 2D graphics.

Sloth Online RPG is a work in progress that will provide a fully graphical online role playing game engine. SlothORPG is coded in Java and is currently in a near playable state featuring several classes with over a thousand lines of code.

My main intentions with this project are to provide a free, fully functional, ever expanding Role Playing Engine (both client and server side) for the end user who would be playing the game. Developers would also be able to use the project as a resource on certain aspects of Java Game Programming.

Server side the project implements the NIO Networking library to create a smoother, stronger tcp/ip core. I found UDP and TCP w/ the old IO library to be unreliable and sluggish respectively. The way in which the server is structured has proven to be strong thus far.

The client side of the code features the Graphics2D Java library to provide near perfect animation without requiring a rendering device such as OpenGL or DirectX.

To summarize my entire intent for this project I basically wanted to provide an Online RPG that is functional on almost any OS that has Java installed and can run just as smooth on low end machines while still being able to feature rich 2-D graphics. The source code is clean and neat as well as commented and organized.

It is easy to read and understand for someone who has some knowledge of Java. As I write this, the project is coming along nicely and some pre-alpha local network testing has proven this. I plan to continue with this project and in the future include database integration and more of a developer-side interface.

A quick rundown of what this project includes so far: Character Creation, Smooth character animation, and fully supported tcp/ip gameplay. Chatting is also implemented.

Unlimited Simulator project is a general purpose simulator.
Unlimited Simulator is not a game. Its a basis to create whatever simulations you want, from games to scientific simulations.
You only have to worry about physics, controls and how the world looks like. It can be at the same time a car simulator, a spaceships war game, or a scientific simulation.
While you can do these things on their own, Unlimited Simulator provides the ability to do all three at once. It allows interaction of completely different kinds of clients, thus achieving unprecedent realism and complexity.
Main features:
- multiplayer: many players by internet or two in your computer;
- create your own vehicles, tracks, terrains, sounds, objects;
- vehicles may have their own physical simulation functions, and interact with the game, creating new objects, destroying others. They can fly or float or move underwater; they can be animals, or surrealistic creations. You create.
- track can contain structures as loops, bridges, banked curves, and anything you can do with polygons;
- creating a track can be done DRAWING on the terrain (not implemented yet);
- objects can be animated and intelligent!
- everything is modular: this means almost all the stuff is plugable! No need to recompile the code;
- last, but not least: GPLed!
Enhancements:
- big debugging in ulengine/primitives.c. Several allocation problems solved.
- review of network code: structs separated in a new header, shared/net.h, and other improvements in code itself.
- review of client plugin format (what functions, names, etc).
- wrappers for the not-so-standard standard C variable types in config.h.
- cosmetic changes in some places, specially ulengine.h.
- BIG debugging in ulengine/project.c and ulengine/graphic.c. Only a billion or so bugs left.
- improved ulengine/demo.c; tests now include graphic functions.
- fixed two small bugs in drawHLine due to rounding.
- added a new projection system. Not tested yet.
- graphics test phase started: drawPixel, drawHLine, drawLine, drawFlatTri and drawShadedTri are working.
- modified POLY_UL structure: SCREENP_UL *projected field was deleted. This field is really unecessary, and deleting it saves 2*sizeof(int) bytes for each vertex. Projections are not individually saved anymore (why should they be after all?). See ulengine/project.c:projectP() to see how projected points are handled.
- added ulengine/image.c, to handle image operations.
- added ulengine/effects.c.
- textures support implemented.
- several small optimizations in ulengine/graphic.c.
- work in the server communications system.
