问题描述
我正在构建这里解释的基本Slick游戏示例:,我遇到了一些问题。具体来说,游戏编译得很好,但是当我尝试运行它时,Java抱怨:
I'm building the basic Slick game example explained here: http://slick.cokeandcode.com/wiki/doku.php?id=01_-_a_basic_slick_game, and I'm running into some problems. Specifically, the game compiles just fine, but when I try to run it, Java complains:
Exception in thread "main" java.lang.UnsatisfiedLinkError: no lwjgl in java.library.path

这是我的源代码:
import org.newdawn.slick.AppGameContainer;
import org.newdawn.slick.BasicGame;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.Image;
import org.newdawn.slick.Input;
import org.newdawn.slick.SlickException;
public class SlickBasicGame extends BasicGame{
Image plane = null;
Image land = null;
float x = 400;
float y = 300;
float scale = 1;
public SlickBasicGame()
{
super("Slick2D Path2Glory - SlickBasicGame");
}
@Override
public void init(GameContainer gc)
throws SlickException {
plane = new Image("data/plane.png");
land = new Image("data/land.jpg");
}
@Override
public void update(GameContainer gc, int delta)
throws SlickException
{
Input input = gc.getInput();
if(input.isKeyDown(Input.KEY_A))
{
plane.rotate(-0.2f * delta);
}
if(input.isKeyDown(Input.KEY_D))
{
plane.rotate(0.2f * delta);
}
if(input.isKeyDown(Input.KEY_W))
{
float hip = 0.4f * delta;
float rotation = plane.getRotation();
x+= hip * Math.sin(Math.toRadians(rotation));
y-= hip * Math.cos(Math.toRadians(rotation));
}
if(input.isKeyDown(Input.KEY_2))
{
scale += (scale >= 5.0f) ? 0 : 0.1f;
plane.setCenterOfRotation(plane.getWidth()/2.0f*scale, plane.getHeight()/2.0f*scale);
}
if(input.isKeyDown(Input.KEY_1))
{
scale -= (scale <= 1.0f) ? 0 : 0.1f;
plane.setCenterOfRotation(plane.getWidth()/2.0f*scale, plane.getHeight()/2.0f*scale);
}
}
public void render(GameContainer gc, Graphics g)
throws SlickException
{
land.draw(0, 0);
plane.draw(x, y, scale);
}
public static void main(String[] args)
throws SlickException
{
AppGameContainer app =
new AppGameContainer( new SlickBasicGame() );
app.setDisplayMode(800, 600, false);
app.start();
}
}
我对原版进行的唯一更改(报告相同的错误),是我删除了包声明。
The only change I've made to the original (which reports the same error), was that I have removed the package declaration.
我从这里下载了Slick:,点击下载完整发行版链接,这里是我的Slick文件夹的样子:
I downloaded Slick from here: http://slick.cokeandcode.com/, by clicking on the "Download Full Distribution" link, and here's how my Slick folder looks like:
我正在编译游戏这个命令:
I'm compiling the game with this command:
javac -cp lib / *:。 SlickBasicGame.java
尝试用这个来运行它:
java -cp lib / *:。 SlickBasicGame
推荐答案
添加 -Djava.library.path = path / to / dir
到命令行或IDE中的VM选项,以便lwjgl能够找到包含本机文件的文件夹。
Add a -Djava.library.path=path/to/dir
to the commandline or as an VM option in your IDE so that lwjgl is able to find the folder containing the native files.
这篇关于线程“main”中的异常java.lang.UnsatisfiedLinkError:java.library.path中没有lwjgl的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
