Java游戏现状

这个demo我也不知道哪一点可笑了，还和盟军2比，我对你没有语言了，我服了，我败了，你厉害。

java web start的demo 每个人都可以load起来看看，省得嘴硬。

我怎么看都没觉得那是海浪,倒象风在吹什么东西.

在我的机器上除了启动慢之外，运行也比较慢啊。呵呵。我机器烂一些。不能怪微软，毕竟他不能帮我升级电脑。

所谓网游服务端，你指的是什么呢？

我个帖子太有意思了。我的回帖也看完了。
JAVA有JAVA的优势，C/C＋＋也有他们的优势。如果这此语言你都熟悉，就不必为某种语言下注了。
可惜啊，人的时间和精力相当有限。

我觉得我的脾气就已经够好了，还真能遇上让我发火的人。
翻翻你自己前面的回帖，错误理论一大堆，我心平气和一条一条给你说明，你倒是跑来一会一句“见见世面”，一会一句“鼠目寸光”。xbox360我的确没买，虚幻、crysis之类的我还是玩过的，目前顶级的游戏引擎是什么表现，网上视频满天飞，我不比你了解的少。

jMonkey Engine是一个开源的免费引擎，我从来没有指望它可以超过次世代主机上的大作用的引擎。即使如此，你做的比较也毫无道理，在硬件条件完全不同的情况下，你是如何得出渲染效率32倍的结论的？还有刚才那个ray_linn，居然拿出盟军敢死队这样和刚才那个海浪demo毫无共同点的东西来比较。你们的逻辑思维真是强大到让我惊讶。

至于jMonkey Engine有没有实用价值，我想已经有人使用它做商业游戏，并且以此为生，就已经证明了它具有实用价值了。

和你俩在这吵终究还是说明我自己的高度也不高，受不了挑衅，其实早就应该不跟你们一般见识。这是我最后一次回复你和ray_linn 的帖子，从现在开始随便你们怎么说，我不再和你俩理论了。

为什么自己没有看到的东西你就在武断的认为别人在杜撰呢？在 Killer Game Programming in Java 这本书里，有这么一段话，An interesting historical observation is that the gaming community used to think that C and C++ were too high-level for fast, efficient games programming when compared to assembly language. Opinions started to change only after the obvious success of games written in C, such as Doom and Dungeon Master, in the mid-1980s. Also important was the appearance of cross-platform development tools that supported C, such as RenderWare.  （从历史观察，一个有趣的现象就是游戏社区过去常认为编写快速有效的游戏，同汇编相比，c和c++因为太高级语言而不适合，只有19世纪80年代中期用c写的doom 和Dungeon Master的成功才改变了这种观点），而且跨平台的透明性支持了c作为开发工具，比如RenderWare.
  为什么说要用发展的眼光看问题，其实作者开篇就提到了用java编写游戏，得到的都是c++社区的嘲笑，可是事物总是在发展的，为什么那么武断的判一个东西的死刑呢？
   作者提到人们认为java不适合游戏开发的理由有:
Java is too slow for games programming.
Java has memory leaks.
Java is too high-level.
Java application installation is a nightmare.
Java isn't supported on games consoles.
No one uses Java to write real games.
Sun Microsystems isn't interested in supporting Java gaming.

对于速度 这是作者原文
This is better rephrased as "Java is slow compared to C and C++, the dominant languages for games programming." This argument was valid when Java first appeared (around 1996) but has become increasingly ridiculous with each new release. Some figures put JDK 1.0, that first version of the language, at 20 to 40 times slower than C++. However, J2SE 5.0, the current release, is typically only 1.1 times slower.

It's worth saying that I think almost all of these objections are substantially wrong. Java is roughly the same speed as C++. Memory leaks can be avoided with good programming and techniques like profiling. Yes, Java is high-level, but it offers more direct access to graphics hardware and external devices. Installation isn't a nightmare if you use decent installation software. There's a growing number of excellent, fun Java games, and an enormous amount of support available from Sun and Sun-sponsored sites.

Tom Clancy's Politika (1997) by Red Storm Entertainment (http://www.redstorm.com/)

This game was written in almost pure Java. Shadow Watch (2000) and Tom Clancy's ruthless.com (1998) mixed Java and C/C++.

A good source for nontechnical lists of Java games, both commercial and freeware/shareware, can be found on the Java games pages at java.com (http://www.java.com/en/games/). The pages divide games into several categories: action, adventure, strategy, puzzle, cards, sports, and so on.

Freeware/Shareware Games
Many Java games are out on the Web, but finding a game that's written well requires a careful search. Many applets date from the late 1990s and were designed using the outdated JDK 1.0 and 1.1 with their feeble media APIs (e.g., graphics, sounds). The initial Java euphoria produced some less than exciting games, more concerned with technical trickery than quality. This large pool of useless applets got Java labeled as a toy language.

Recent versions of Java are different. The speed has improved and APIs crucial to gamingsuch as graphics and audioare of a high quality. There's been a move away from applets towards the downloading of client-side applications using JWS.

Java's backward compatibility allows the applets from 1996 to 1998 to be executed, and they'll often run quicker than the original applets. However, it's probably best to steer clear of these Java dinosaurs and look for more modern code.

Numerous web sites use Java games. The emphasis of the following list is on applications/applets for playing:




Java Games Factory (JGF) (http://grexengine.com/sections/externalgames/)

There aren't many games at this site (about 50), but they're all high quality. The aim is to show off various modern Java game technologies.




ArcadePod.com (http://www.arcadepod.com/java/)

Over 750 Java games, nicely categorized.




Java 4 Fun (http://www.java4fun.com/java.html)

Similar in style to ArcadePod, with a good set of links to other sites.




jars.com (http://www.jars.com)

A general Java site with a ratings scheme. There are many games, but a lot of them are old applets.




Java Shareware (http://www.javashareware.com/)

Another general site: look under the categories applications/games and applets/games.




Java Games Central (http://www.mnsi.net/tild rkerr/)

A personal web site that lists games with ratings and links. It was last updated in 2001.

Some of my favorite freeware/shareware games are:




Super Elvis; also known as Hallucinogenesis (http://www.puppygames.net/downloads/hallucinogenesis/hallucinogenesis.jnlp)

This game won the Sun Microsystems 2004 Technology Game Development Contest. Super Elvis can be downloaded from the puppygames web site using JWS.




FlyingGuns (http://www.flyingguns.com/)

A 3D multiplayer WWI fighter plane game/simulator. This came second in the contest but is my favorite.




Cosmic Trip (http://www.mycgiserver.com/tild movegaga/cosmictrip.html)

An arcade-style 3D game with striking graphics.




Squareheads (http://home.halden.net/tombr/squareheads/squareheads.html)

A multiplayer FPS (it came third in the developer contest).




Escape (http://javaisdoomed.sourceforge.net/)

A Doom-like FPS.




CazaPool3D (http://membres.lycos.fr/franckcalzada/Billard3D/Pool.html)

A pool game that allows online (single/multiplayer) play in an applet or as a standalone application.

Programmers looking for source code should start at one of the following sites:




SourceForge (http://sourceforge.net/search/)

SourceForge acts as a repository and management tool for software projects, many with source code. A recent search for (java + game) returned over 70 projects that had 40 percent or greater activity. One of the drawbacks of SourceForge is that deciding if a project is vaporware is difficult. Good projects that have been completed will show low activity after a time, dropping down the list of search results.




FreshMeat.com (http://freshmeat.net/)

FreshMeat maintains thousands of applications, most released under open source licenses. The search facilities are excellent and can be guided by game category terms. The results include rating, vitality, and popularity figures for each piece of software. A recent search for Java in the Games/Entertainment category returned nearly 70 hits. Many applications turn up at SourceForge and FreshMeat.




The "Your Games Here" Java Games Forum (http://www.javagaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=Announcements)

Implementers can post links to their games, and (perhaps more importantly) users can post their opinions as follow-ups.




Code Beach (http://www.codebeach.com)

CodeBeach has a searchable subsection for Java games that contains nearly 90 examples.




Programmers Heaven (http://www.programmersheaven.com/zone13/)

It has a "Java zone" containing some games.

看了java开发游戏wurm,我感觉java开发大型3D(i td= fhw 不知道你们有没有玩过WURM)技术真的没什么问题了,说消耗内存吧,我看wurm也只是300-500M之间,现在硬件配置没什么问题吧.现在java开发游戏性能还没有最优化(不想C已优化那么多年,提升的空间应当相对java来说是少的了).java性能提升空间还是很大的.目前环境java已有做出.wurm这样水平的游戏,我对他未有信心,在不久将来.将会出现更多,更优秀java大型游戏.

WURM,图形只能到了差强人意的地步,稳定性更是糟糕...

请看TOM的报导:

"上周奇幻MMORPG游戏《Wurm Online》的服务器全线崩溃，数据全部损失。游戏开发方预计玩家损失的游戏时间共计超过50万小时。

经过一段时间的调整，官方宣布将于5月5日重开《Wurm》游戏的服务器，至于损失的时间，玩家将会得到赔偿。老玩家可以重新获得之前购买的所有金币。另外得到额外两周的游戏时间。为了安全起见，同时官方也额外安排了离线自动数据备份等防范措施，预防此次事件再次发生"

我们从来没有争辩Java能不能写出游戏,而是Java能成为主流3D开发语言吗? WURM的画面是能和任何一款当前的3D游戏媲美么? 你能把WURM跟"华丽"二个字挂上钩么? WOW也才区区300M内存, WURM难道不算内存大户了么?

I have a 2D engine written in both Java and C++. If I draw using the OpenGL immediate mode (glVertex) i get about 1/3 of the vertex output i'd get with C++, however if i use Vertex Buffer Objects the amount is perhaps 3/4 of the amount in C++ engine.

For simple games I don't see the problem in this, however for example as you can see that concentration camp simulator (Wyrm Online, Wurm Online?) doesn't run very well, although it is very pretty. I think it's a great example of when one should / shouldn't use Java. It's impossible to get reasonable framerates when compared to other commercial products of that scale.

现在应用内存用个1G有什么压力吗?何况没达到1G,wow也有崩溃的,wow你知道,脚本是什么写的吗,你是不是觉得是C++啊, ,LUA!!!
