Hello there, I've been developing a 2D turn-based fighting game called THE SCND GENESIS:Legends in Java. Its story is based on my web-comic
http://scndgen.sourceforge.net. Its not out yet but development is proceeding smoothly. Though I'ld like to discuss some stuff with you guys
Firstly graphics. I love polygons as much as the next guy, but 3D has it's pitfalls. I t adds an extra dimension, no pun intended, of complexity. I believe more developers should give good old 2D a spin before going 3D. Commercial games like Muramasa: The Demon Blade (Wii) and Blaz Blue (HD Consoles) show that 2D games still have the ability to be visually spectacular. Here are some screens:
What do you think, several stages and characters aren't published but that should give you a general "feel" of its look. More screens are available on the site
http://scndgen.sourceforge.net/game.htmlPerformance. The game uses Java2D and Volatile Image, no fancy JOGL, Slick, LWJGL here >_<. Buffered Image was crazily slow, so I use standard images. Initially I had lame performance, but that's because I was drawing and filling several arcs, rectangles and polygons *facepalm*. After replacing them with static Images, performance became great. It uses 75% of a Celeron M 1.4GHz in Windows Vista. On my Pentium E2180, I get 13 % CPU utilisation, and 124 MB RAM usage on average. Trust me, that's A LOT better than before.
Multiplayer. The game already works on LAN. It has a lobby/matchmaking system that's fairly decent. The host machine acts as a server and the other as a client. Performance is great, no latency or anything. I've already created an online server and tested it numerously on local host, works good. But I havn't been able to do find any free online hosting (hey, I'm a student, and broke). Could you suggest some sites.
Lastly, Licensing. I want this game to have a Licence like that of Warsow. The code/engine shall be free to edit. But the art, story and other intellectual property related to my web-comic belongs to me. ow do I go around that. I want this game to be freely available, but I don't want my characters and Story to be changed by random people................................................................................SNAP!!!! I had an idea. Since its open source, the characters are mine, but people get a basic plot premise and create their own episodes...or outcomes. They could be combined to one game to make some kinda Mass Effect 2 conversation reel, multiple outcome thing *brain stromz*.
Oh well, that's it. Heres the code from my drawGame class, which renders graphics. It'll give you an idea of how the game is structured. Please comment and makes suggestions.
