LWJGL 3D运动

Question

我想创建一个使用LWJGL的FPS相机，但我的代码似乎不工作。 -_- 它只是在屏幕前创建一个白色块，玩家不能移动或旋转。 问题是什么？

public class LocalWindow 
{ 
public void Launch() 
{ 
    try 
    { 
     Display.setDisplayMode (new DisplayMode (800, 600)); 
     Display.setTitle("Historica"); 
     Display.create(); 
    } 
    catch (LWJGLException e) 
    { 
      e.printStackTrace(); 
    } 
} 
public void Render() 
{ 
    initMatrix(); 
    while (!Display.isCloseRequested()) 
      //&& !Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) 
    { 

     initControls(); 
     frameRefresh(); 
     initCamera(); 




     Block s = new Block(0, 0, -4); 
     s.setBlock(); 






     Display.update(); 
    } 
} 
private void initCamera() 
{ 
    Camera player = new Camera(); 
    player.setView(); 
} 
private void frameRefresh() 
{ 
    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); 
    glLoadIdentity(); 
} 
private void initControls() 
{ 
    Mouse.setGrabbed(true); 
    Controls controls = new Controls(); 
    controls.moveForward(0.1f); 
    controls.moveBackward(0.1f); 
    controls.strafeLeft(0.1f); 
    controls.strafeRight(0.1f); 
    controls.lookingAround(0.1f); 
} 
private void initMatrix() 
{ 
    Matrix matrix = new Matrix(); 
    matrix.initMatrix(); 
} 

}

Camera类：

public class Camera { 
public float x; 
public float y; 
public float z; 
public float rx; 
public float ry; 
public float rz; 
public float fov = 70; 
public float aspect = (float)Display.getWidth()/(float)Display.getHeight(); 
public float near = 0.3f; 
public float far = 1000; 
public float dx; 
public float dy; 



public void setView(){ 
    glRotatef(rx,1,0,0); 
    glRotatef(ry,0,1,0); 
    glRotatef(rz,0,0,1); 
    glTranslatef(x,y,z); 
} 
} 

的控件类：

import org.lwjgl.input.Keyboard; 
import org.lwjgl.input.Mouse; 


public class Controls extends Camera { 
boolean W = Keyboard.isKeyDown(Keyboard.KEY_W); 
boolean S = Keyboard.isKeyDown(Keyboard.KEY_S); 
boolean A = Keyboard.isKeyDown(Keyboard.KEY_A); 
boolean D = Keyboard.isKeyDown(Keyboard.KEY_D); 

public void moveForward(float amount) 
{ 
    if(W) 
    { 
    x += amount * Math.cos(Math.toRadians(ry + 90)); 
    z += amount * Math.sin(Math.toRadians(ry + 90)); 
    } 
} 

public void moveBackward(float amount) 
{ 
    if(S) 
    { 
    x -= amount * Math.cos(Math.toRadians(ry + 90)); 
    z -= amount * Math.sin(Math.toRadians(ry + 90)); 
    } 
} 
public void strafeLeft(float amount) 
{ 
    if(A); 
    { 
    x -= amount * (float)Math.sin(Math.toRadians(ry-90)); 
    z += amount * (float)Math.cos(Math.toRadians(ry-90)); 
    } 
} 
public void strafeRight(float amount) 
{ 
    if(D) 
    { 
    x -= amount * (float)Math.sin(Math.toRadians(ry+90)); 
    z += amount * (float)Math.cos(Math.toRadians(ry+90)); 
    } 
} 
public void lookingAround(float amount) 
{ 
    dx = Mouse.getDX(); 
    dy = Mouse.getDY(); 
    ry += dx * amount; 
    rx -= dy * amount; 
} 
} 

Matrix类：

public class Matrix extends Camera{ 
public void initMatrix(){ 
    glMatrixMode(GL_PROJECTION); 
    glLoadIdentity(); 
    gluPerspective(fov, aspect, near, far); 
    glMatrixMode(GL_MODELVIEW); 
    glEnable(GL_DEPTH_TEST); 
    glEnable(GL_TEXTURE_2D); 
} 

}

类块的工作原理完全正确（它创建在给定的坐标的三维块）。

为什么你的相机不动的原因是，你在每帧创建的player和controls一个新的实例。除此之外，您仅在控件中更改成员，但使用播放器中的值设置视图。
