Question

我有一个带有偏航和俯仰角的相机。

相机的位置是x，y和z。

我需要一种平移偏航和按下按钮（WASD）来沿x和z移动的方法。

因此，我按W键，摄像机矩阵向后移动，看起来像是根据偏航角向前移动，但是我不知道这样做的公式。

相机类（我认为这不是必需的）：

public static Vector3f position = new Vector3f(0, 1, 0);
public static double sensitivity;
private float pitch;
private float yaw;
private float roll;
private boolean escape;
private boolean fullscreen;

public Camera() {
    escape = false;
    fullscreen = false;
    Mouse.setGrabbed(true);
}

public void move() {
    if (Keyboard.isKeyDown(Keyboard.KEY_ESCAPE)) {
        if (escape == true) {
            Mouse.setGrabbed(true);
            Mouse.setCursorPosition(Display.getWidth()/2, 
            Display.getHeight()/2);
            escape = false;
        } else if (escape == false) {
            Mouse.setGrabbed(false);
            escape = true;
        }
    }
    //Not working rn
    if (Keyboard.isKeyDown(Keyboard.KEY_GRAVE) && escape == false) {
        if (fullscreen == true) {
            try {
                Display.setFullscreen(false);
            } catch (LWJGLException e) {
                e.printStackTrace();
            }
            fullscreen = false;
        } else {
            try {
                Display.setFullscreen(true);
            } catch (LWJGLException e) {
                e.printStackTrace();
            }
            fullscreen = true;
        }
    }
    //Change pitch based off of mouse y
    if (Mouse.getY() != Display.getHeight() / 2 && escape == false) {
        pitch += (Display.getHeight()/2 - Mouse.getY())/2;
        if (pitch > 360) {
            pitch = pitch % 360;
        }
    }
    //Change yaw with mouse movement
    if (Mouse.getX() != Display.getWidth() / 2 && escape == false) {
        yaw -= (Display.getWidth()/2 - Mouse.getX())/2;
        if (yaw > 360) {
            yaw = yaw % 360;
        }
    }
    //get out of the game
    if (escape == false) {
        Mouse.setCursorPosition(Display.getWidth() / 2, Display.getHeight() 
        /2);
    }

    //Here is the movement code, currently just moves along x/z normally
    if (Keyboard.isKeyDown(Keyboard.KEY_S) && escape == false) {
        position.x -= (Math.sin(yaw)*.2)*sensitivity;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_W) && escape == false) {
        position.x += (Math.sin(yaw)*.2)*sensitivity;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_A) && escape == false) {
        position.z -= (Math.cos(yaw)*.2)*sensitivity;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_D) && escape == false) {
        position.z += (Math.cos(yaw)*.2)*sensitivity;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_LSHIFT) && escape == false) {
        position.y -= 0.015;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_SPACE) && escape == false) {
        position.y += 0.015;
    }
}

public Vector3f getPosition() {
    return position;
}

public float getPitch() {
    return pitch;
}

public float getYaw() {
    return yaw;
}

public float getRoll() {
    return roll;
}

在这里[How to move my camera straight to mouse cursor, with any rotation?

找到了解决方案

由于某种原因，如果我向前看，我的W向前移动，如果我向后看，我向后移动，但是两者之间没有。

新代码：

公共静态最终Vector3f getRotationVector（）{ float r =（float）Math.toRadians（roll）; Matrix4f mat = GameMath.createTransformationmatrix（new Vector3f（），pitch，yaw，0，1）; Vector3f vector =新的Vector3f（mat.m20，mat.m21，-mat.m22）; 返回新的Vector3f（（float）（vector.x * Math.cos（r）+ vector.y * Math.sin（r）），（float）（vector.y * Math.cos（r）-vector.x * Math.sin（r）），vector.z）; }

运动：

if (Keyboard.isKeyDown(Keyboard.KEY_S) && escape == false) {
        position.x -= getRotationVector().x;
        position.z -= getRotationVector().z;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_W) && escape == false) {
        position.x += getRotationVector().x;
        position.x += getRotationVector().z;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_A) && escape == false) {
        position.z -= getRotationVector().z;
        position.x -= getRotationVector().x;
    }

    if (Keyboard.isKeyDown(Keyboard.KEY_D) && escape == false) {
        position.z += getRotationVector().z;
        position.x += getRotationVector().x;
    }
