Source versions may not be "relicensed" under a different license + without my explicitly written permission. + + +LICENSE NOTES +============= +The license covers the source code found in the "src" directory of this +archive, the included enet network library which cube uses is covered by +the "No problem Bugroff" license, which is however compatible with the +above license for all practical purposes. + +Game media included in the cube game (maps, textures, sounds, models etc.) +are not covered by this license, and may have individual copyrights and +distribution restrictions (see individual readmes). + + +USAGE +===== +Compiling the sources should be straight forward. + +Unix users need to make sure to have the development version of all libs +installed (OpenGL, SDL, SDL_Mixer, SDL_Image, zlib, libpng). The included +makefiles can be used to build. + +Windows users can use the included visual studio .net 2003 project files, which +references the lib/include directories for the external libraries and should +thus be self contained. The project is set up assuming you have the normal +cube binary distribution as a subdirectory "cube" of the root of this archive, +so release mode builds will place executables in the bin dir ready for testing +and distribution. Do not come ask me for help in compiling or modifying the +sources, if you can't figure out how to do this yourself you probably shouldn't +be touching the files anyway. + +The cube sources are very small, compact, and non redundant, so anyone +wishing to modify the source code should be able to gain an overview of +cube's inner workings by simply reading through the source code in its +entirety. Small amounts of comments should guide you through the more +tricky sections. + +When reading the source code and trying to understand cube's internal design, +keep in mind the goal of cube: minimalism. I wanted to create a very complete +game / game engine with absolutely minimal means, and made a sport out of it +keeping the implementation small and simple. Cube is not a commercial product, +it is merely the author's idea of a fun little programming project. + + +OPEN SOURCE +=========== +Cube is open source (see ZLIB license above). This only means that you have +great freedom using it for your own projects, but does NOT mean the main cube +code is an "open source project" in the sense that everyone is invited to +contribute to it. The main cube code will remain a one man project (me), as my +minimalistic design is highly incompatible with the open source philosophy. If you +add to the cube source code, you fork the code and it becomes your own project, +do not ask for me to integrate your changes into the main branch, no matter +how brilliant they are. + + +CHEATING +======== +If you want to use cube as a base for a game where the multiplayer aspect is +important and used by a large community, you need to be aware that cube's +thick client - thin server architecture is extremely cheat sensitive. If you +release a cube based game with source code equivalent to the binaries, some +minor changes can give anyone an aimbot or other cheats in online games. +There are several ways to make this less easy, some of which are: + +1. only distribute binaries (the ZLIB license allows this). Executables can still + be hacked, but unless you have a really large online community, noone will + probably bother. +2. write a network proxy, such as qizmo used with QuakeWorld (whose sources are + also open source). The proxy is a small closed source program that checksums + the executable, and maybe also some game media. You can then make servers + or game admins request this information and ban cheaters. +3. release the sources with an incompatible network protocol or other changes + compared to the binaries you release. +4. build serious cheat detection into the game. Since all clients are their own + "servers", you can make them all keep track of stats for the other players, + such as health etc. you can make all sorts of consistency checks on shots, + movement speed and items. If the discrepancy for a certain client becomes + too big, all clients but the cheater can send their "vote" to the server + for having him banned. Even better, you can add server side stat checking. + +For the cube's own game I chose option 3, i.e. you can only play the official +cube game using the binaries supplied by me, and you can't compile your own clients +for multiplayer use (you can still make custom clients that work with matching +custom servers, or play cube single player maps compatible with the real thing). +This situation is not ideal, but there is no easy way around it. + +This scheme is probably very easy to defeat if you are capable of using disassemblers +and packet sniffers, but please contrain yourself and don't ruin the fun of the +cube multiplayer community.
