unity fps 旋转相机 [英] Unity fps rotation camera

问题描述

在我的游戏中，我有一个摄像头，我想在这个摄像头上附加一个像旋转一样的 FPS.

In my game I have a camera and I want to have an FPS like rotation attached to this camera.

因此，如果我将光标向左移动，我希望我的凸轮向左旋转.如果我向上移动光标，那么凸轮应该向上看，等等.

So if I move my cursor to the left, I want my cam to rotate to the left. If I move my cursor up, then the cam should look up, etc.

我目前让它部分工作.我可以左右看，上下看.当我向下看然后左右移动光标时会出现问题.然后它给了我一个滚动"效果.

I currently have it partially working. I can look left and right, up, and down. The problem occurs when I look down and then move my cursor left and right. It then gives me a "Roll" effect.

显然，当我向下看时，我仍然想要偏航"效果而不是滚动"效果.任何人都知道如何做到这一点?这是我目前所拥有的:

Obviously when I look down I still want to have a "Yaw" effect instead of a "Roll" effect. Anyone any idea how to do that? This is what I have so far:

// Update is called once per frame
public override void update ()
{
    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityRoll * Input.GetAxis("Vertical"), Vector3.forward );

    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityYaw * Input.GetAxis("Mouse X"), Vector3.up );

    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityPitch * Input.GetAxis("Mouse Y"), Vector3.left );
}

我刚刚在这个话题中找到了答案:

I just found my answer in this topic:

来自该主题的代码:

C# Mono 代码:

C# Mono code:

using UnityEngine;
using System.Collections;

/// MouseLook rotates the transform based on the mouse delta.
/// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character:
/// - Create a capsule.
/// - Add the MouseLook script to the capsule.
///   -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
/// - Add FPSInputController script to the capsule
///   -> A CharacterMotor and a CharacterController component will be automatically added.

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
/// - Add a MouseLook script to the camera.
///   -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook : MonoBehaviour {

    public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
    public RotationAxes axes = RotationAxes.MouseXAndY;
    public float sensitivityX = 15F;
    public float sensitivityY = 15F;

    public float minimumX = -360F;
    public float maximumX = 360F;

    public float minimumY = -60F;
    public float maximumY = 60F;

    float rotationY = 0F;

    void Update ()
    {
        if (axes == RotationAxes.MouseXAndY)
        {
            float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;

            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
        }
        else if (axes == RotationAxes.MouseX)
        {
            transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
        }
        else
        {
            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
        }
    }

    void Start ()
    {
    //if(!networkView.isMine)
        //enabled = false;

        // Make the rigid body not change rotation
        //if (rigidbody)
            //rigidbody.freezeRotation = true;
    }
}
