Question

JAVA可以做出游戏么

我一直想用一个语言做一个游戏出来，大1学完C之后就想用C编一个游戏出来的，可以没法用图形库文件，没做成。现在都快大4了，在不做我怕来不及了，到现在为至，JAVA学的有一半了，不知道能不能用JAVA做出游戏出来，请知道的告诉一下，谢谢。

Answer 1

可以的，我就做过一个即时战略游戏。Java最大的问题是性能比较差。如果你不做非常复杂的游戏就可以光用Java。
做复杂的2D游戏或者3D游戏可以用JOGL(Java的OpenGL)，性能还是比C要差一些，但一般的游戏足够了。
让用户安装JVM并不是大问题。不说现在大部分电脑都已经安装了JRE，你也可以捆绑一个不用安装的JVM和你的游戏一起。比如JRE6一共有86 MB。作为比较Adobe Reader(看pdf文件用的)有41.1 MB，一般不会有人嫌这个东西太大而不下载的。

Answer 2

我知道C的,软件用WIN-TC,代码如下:
#include<stdio.h>
#include<graphics.h>
#include<bios.h>
#include<stdlib.h>
#include<conio.h>

#define BC LIGHTBLUE
#define FC RED
#define LEFT 0x4b00
#define RIGHT 0x4d00
#define DOWN 0x5000
#define UP 0x4800
#define ESC 0x011b
#define ONE 0x231
#define TWO 0x332
#define THREE 0x433

唉，楼主和我有一样的梦想啊，我也马上大四了，时间真快啊...

这个问题是这样的。

游戏要看是什么游戏，我这里说的是3D游戏，我相信你的意思也不是要做个扫雷，呵呵。

游戏开发常用的框架说白了就是DirectX，OpenGL确实大不如当前了。因为游戏开发大量设计与系统底层的交互，而这恰恰是Java程序的软肋。Java必须使用JNI调用本地库才能实现硬件3D加速，这当然比直接开发的本地代码效率低的多，所以目前用Java做3D游戏的相当少。

但这并不代表Java不能进行3D开发，java.net维护的java3d项目，https://java3d.dev.java.net/，就是一个j2se上的3d API。可以说是3d在Java上的官方实现。

具体说到3D游戏，Java确实是可以做出高水平的3D游戏的。你关注游戏开发的话应该知道一些C++的开源游戏引擎，比如Ogre什么的。Java方面也有比较成熟的游戏引擎，有一个开源项目叫java monkey engine，在JavaOne 2008上还是很受瞩目的，它应该是基于Java3D实现。http://www.jmonkeyengine.com/ 这个是它的网站，上面有很多Demo，你可以慢慢看看。

Answer 4

java做游戏不现实。可能WEB GAME还可以。你想别人玩CS（这个不是枪战）类型的游戏。玩你个不大的游戏还必须装JVM，很多用户肯定不愿意。

Answer 5

java一般都是做小型的手机游戏之类的。
不过好像现在出了一个Java做到网络游戏。
