我需要在世界空间中相对于主摄影机面对的方向移动目标对象，但仅在x和z轴上移动，并相对于y轴上的我的播放器移动

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {

您可以像这样获得相机的方向：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

var camDir = Camera.main.transform.forward;
您只需要x/y分量，因此我们将重新规范化该向量：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

camDir.y = 0;
camDir.Normalized();

var playerUp = Vector3.up;
这是正向矢量。因为它现在实际上是一个二维矢量，我们可以很容易地得到凸轮的右侧矢量：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

var camRight = new Vector3(camDir.z, 0f, -camDir.x);
我假设你的玩家的上方向是y轴上。如果它不同，在那个向量中：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

camDir.y = 0;
camDir.Normalized();

var playerUp = Vector3.up;
现在，在您的示例中，您正在进行手动积分，然后将其传递给刚体系统以再次进行积分。让我们直接计算出我们自己的速度：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

var newVel = Vector3.zero;
if (/*left*/) newVel -= camRight * 0.05;
if (/*right*/) newVel += camRight * 0.05;
if (/*closer*/) newVel -= camDir * 0.05;
if (/*farter*/) newVel += camDir * 0.05;
if (/*raise*/) newVel += playerUp * 0.05;
if (/*lower*/) newVel -= playerUp * 0.05;
如果你想移动得更快或更慢，可以更改为0.05。你可以在这里做很多事情来让控件感觉非常好，比如有一个小死区，或者直接输入模拟输入而不是按钮

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}
然后最后将其提交到刚体中：

public class test : MonoBehaviour {

public string raise = "Raise";
public string lower = "Lower";
public string left = "Left";
public string right = "Right";
public string closer = "Closer";
public string further = "Further";

public GameObject target;


private float xPos;
private float yPos;
private float zPos;


// Use this for initialization
void Start () {


    xPos = target.transform.position.x;
    yPos = target.transform.position.y;
    zPos = target.transform.position.z;

}

void FixedUpdate () {

    Vector3 currPos = target.transform.position;
    Vector3 nextPos = new Vector3 (xPos, yPos, zPos);

    target.GetComponent < Rigidbody > ().velocity = (nextPos - currPos) * 10;

    if (Input.GetButton (raise)) {
        print ("Moving Up");
        yPos = yPos + 0.05f;
    }
    if (Input.GetButton (lower)) {
        print ("Moving Down");
        yPos = yPos - 0.05f;
    }
    if (Input.GetButton (left)) {
        print ("Moving Left");
        xPos = xPos - 0.05f;
    }
    if (Input.GetButton (right)) {
        print ("Moving Right");
        xPos = xPos + 0.05f;
    }
    if (Input.GetButton (closer)) {
        print ("Moving Closer");
        zPos = zPos - 0.05f;
    }
    if (Input.GetButton (further)) {
        print ("Moving Further");
        zPos = zPos + 0.05f;
    }
}

target.GetComponent<Rigidbody>().velocity = newVel;

target.GetComponent（）.velocity=newVel；
谢谢你的精彩回答，tenpn，这确实帮了我的忙。但现在，当我松开上升按钮时，高度会重置。那么，我要去currentPos-newVel吗？我需要更多详细信息。你从地板开始，点击上升，然后发生什么？你想发生什么？好的，我明白了，这是一个遥控系统，所以当我按下上升对象按钮时，它应该d设置物体离地面的高度，当我松开按钮时，保持在该位置。然后刚体是错误的答案。执行类似操作，但将
.velocity=call
替换为
target.transform.position+=newVel*Time.deltaTime
。如果刚体不需要移动，则将其从物体上移除我现在很困惑，为什么我不能使用刚体？有没有办法得到我现有的相对于相机的代码？当我像我需要的那样松开按钮时，它就会悬浮起来。
