IntelliJ 中的 LWJGL 控制器

Question

每次我尝试构建一个使用 LWJGL 控制器的基本示例程序时，它都会崩溃。代码如下：

package com.czipperz.blogspot.tests.controllers;


import org.lwjgl.LWJGLException;
import org.lwjgl.input.Controller;
import org.lwjgl.input.Controllers;

/**
 * Created by Chris on 10/23/2014.
 */
public class Main {
//left joystick x and y
private float x, y,
//right joystick x and y.  Like the commas?
              rx, ry;
//This Controller object MUST BE org.lwjgl.input.Controller NOT net.java.games.input.Controller
private Controller c;
private boolean start;

public static final int BUTTON_A = 1, BUTTON_B = 2, BUTTON_X = 3, BUTTON_Y = 4,
                        BUTTON_LEFT_BUMPER = 5, BUTTON_RIGHT_BUMPER = 6, BUTTON_SELECT = 7, BUTTON_START = 8,
                        //When you PRESS the joysticks (click)
                        BUTTON_LEFT_JOYSTICK = 9, BUTTON_RIGHT_JOYSTICK = 10;

public static void main(String[] args) {
    new Main();
}

public Main() {
    //Says, find controllers and store them in the Controllers class to JInput. Dont worry bout it.
    try {
        Controllers.create();
    } catch (LWJGLException e) {
        e.printStackTrace();
    }
    // Gets you a shiny "new" controller instance.
    // Think of index like you would think of an array.
    c = Controllers.getController(0);

    //Sets "deadband"
    float dead = .06f;
    c.setXAxisDeadZone(dead);
    c.setYAxisDeadZone(dead);
    c.setRXAxisDeadZone(dead);
    c.setRYAxisDeadZone(dead);

    //Using the controller requires you to call the poll() function to receive new data.
    c.poll();
    x = c.getXAxisValue();
    y = c.getYAxisValue();
    rx = c.getRXAxisValue();
    ry = c.getRYAxisDeadZone();
    //NOTE: getZAxisValue(), getRZAxisValue(), getZAxisDeadZone(), getRZAxisDeadZone() DO NOT WORK

    //DPAD = POV
    float povx = c.getPovX();
    float povy = c.getPovY();

    boolean lbumper = c.isButtonPressed(BUTTON_LEFT_BUMPER);
}
}

问题是每次我构建时，都是这样的日志：（对不起，我不能多次点击空间）

Answer 1

我知道这个帖子很旧，但对于正在寻找解决方案的人来说。 答案是，您必须将本机库包含到您的项目中。要使用 jinput.jar，您必须包含以下库：

• jinput-dx8.dll
• jinput-dx8_64.dll
• jinput-raw.dll
• jinput-raw_64.dll

你可以在这里DOWNLOAD下载本地人。

1. 您将获得一个 jar 文件。使用 winrar 解压文件以获取 dll 文件。
2. 现在转到项目并单击鼠标右键打开上下文菜单 -> 构建路径 -> 配置构建路径 -> 选择库选项卡 -> 单击 jinput.jar 旁边的小箭头以展开视图 -> 在 Native library location 上双击鼠标左键 -> 选择 dll 文件的目录。
3. 确认对话框并再次尝试运行您的程序。

Answer 2

在 LWJGL 中有一个“native/”文件夹，其中包含每个平台/操作系统各自的本地库。只需选择您的平台并将 java.library.path 设置为该目录即可。 这是你的问题。

第一步： 创建一个文件夹并将其重命名为 LWGJL_New，然后在该文件夹中创建另外两个文件夹，并将第一个文件夹重命名为 libs，第二个重命名为 natives。 现在转到您已下载的 LWGJL 库。将 jar 文件复制到 LWGJL_New/libs。然后转到您下载的 LWGJL 库，其中有一个文件夹，其中包含每个平台/操作系统的相应本机库。 选择其中一个您需要的并将其复制到 LWGJL_New/natives。

第二步： 转到项目的模块设置（F4），然后单击库。单击添加符号（+）。单击 java。现在找到 LWGJL_New 文件夹并在其中单击 jar 文件夹并单击确定。然后点击应用确定。

第三步： 现在如果你运行你的项目就会出现这个问题，所以去编辑配置部分

然后在 VM 选项中写下：

-Djava.library.path="***"

用我们刚刚创建的 native 文件夹的地址代替星号。

例如->

 D:\LWGJL_New\natives\windwos
 D:\LWGJL_New\natives\linux

然后点击确定。 然后运行你的项目。
