Question

我只是在研究Unity5，因为这是我的学校项目。他们告诉我做一个fps游戏，我尝试制作一个fps，让相机按Q和E旋转，但我不能用鼠标移动相机。当我想输入鼠标时，我根本无法移动我的fps角色。这是我的代码：

using UnityEngine;

public class Player : MonoBehaviour {

private MazeCell currentCell;

private MazeDirection currentDirection;

public void SetLocation (MazeCell cell) {
    if (currentCell != null) {
        currentCell.OnPlayerExited();
    }
    currentCell = cell;
    transform.localPosition = cell.transform.localPosition;
    currentCell.OnPlayerEntered();
}

private void Move (MazeDirection direction) {
    MazeCellEdge edge = currentCell.GetEdge(direction);
    if (edge is MazePassage) {
        SetLocation(edge.otherCell);
    }
}

private void Look (MazeDirection direction) {
    transform.localRotation = direction.ToRotation();
    currentDirection = direction;
}

private void Update () {



    if (Input.GetKeyDown(KeyCode.W) || Input.GetKeyDown(KeyCode.UpArrow)) {
        Move(currentDirection);
    }
    if (Input.GetKeyDown(KeyCode.D) || Input.GetKeyDown(KeyCode.RightArrow)) {
        Move(currentDirection.GetNextClockwise());
    }
    if (Input.GetKeyDown(KeyCode.S) || Input.GetKeyDown(KeyCode.DownArrow)) {
        Move(currentDirection.GetOpposite());
    }
    if (Input.GetKeyDown(KeyCode.A) || Input.GetKeyDown(KeyCode.LeftArrow)) {
        Move(currentDirection.GetNextCounterclockwise());
    }
    if (Input.GetKeyDown(KeyCode.Q)) {
        Look(currentDirection.GetNextCounterclockwise());
    }
    if (Input.GetKeyDown(KeyCode.E)) {
        Look(currentDirection.GetNextClockwise());
    }
}

}

Answer 1

首先，您应该更新更新功能中的“else if”并将其替换为简单的“if”。因为只要你的一个if语句为真，就会跳过以下函数。应该解决它。

试试这个：

public class Player : MonoBehaviour {
//Position of mouse since last change in viewdirection
private float mousePosLast;

//Tollerance of mouse input 
//this is optional but makes the the input not that sensitive
public float mouseTollerance;

//sets the correct position of mouse on start
public void Start () {
    mousePosLast = Input.mousePosition.x;
}


public void Update () {
    /*
    ...other update code...
    */

    if (Input.GetKeyDown(KeyCode.Q)) {
               Look(currentDirection.GetNextCounterclockwise());
        }
        if (Input.GetKeyDown(KeyCode.E)) {
            Look(currentDirection.GetNextClockwise());
        }

    //check if change in mouse position is big enougth to trigger camera rotation
    if(Mathf.Abs(Input.mousePosition.x - mousePosLast) > mouseTollerance){
        //check whether to turn right or left
        if(Input.mousePosition.x - mousePosLast > 0){
            Look(currentDirection.GetNextCounterclockwise());
        }else{
            Look(currentDirection.GetNextClockwise());
        }
    }
}

private void Look (MazeDirection direction) {
        transform.localRotation = direction.ToRotation();
       currentDirection = direction;

    //set mousePosLast to current mouseposition on every change -> avoids strange effects
    mousePosLast = Input.mousePosition.x;
}

}
