c# /Unity相机旋转

本文关键字：旋转 相机 Unity | 更新日期: 2023-09-27 18:12:58

我试图使它，使相机始终跟随球，但我只能旋转它，当我按下右键。虽然，现在，它只跟着球当我按住鼠标右键。有办法把这两者分开吗?

using UnityEngine;
using System.Collections;
public class Orbit2 : MonoBehaviour {
public Transform target;
public float distance = 5.0f;
public float xSpeed = 120.0f;
public float ySpeed = 120.0f;
public float yMinLimit = -20f;
public float yMaxLimit = 80f;
public float distanceMin = .5f;
public float distanceMax = 15f;
private Rigidbody rigidbody;
float x = 0.0f;
float y = 0.0f;
// Use this for initialization
void Start()
{
    Vector3 angles = transform.eulerAngles;
    x = angles.y;
    y = angles.x;
    rigidbody = GetComponent<Rigidbody>();
    // Make the rigid body not change rotation
    if (rigidbody != null)
    {
        rigidbody.freezeRotation = true;
    }
}
void LateUpdate()
{
    if (target
        && Input.GetMouseButton(1))
    {
        x += Input.GetAxis("Mouse X") * xSpeed * distance * 0.02f;
        y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
        y = ClampAngle(y, yMinLimit, yMaxLimit);
        Quaternion rotation = Quaternion.Euler(y, x, 0);
        distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel") * 5, distanceMin, distanceMax);
        RaycastHit hit;
        if (Physics.Linecast(target.position, transform.position, out hit))
        {
            distance -= hit.distance;
        }
        Vector3 negDistance = new Vector3(0.0f, 0.0f, -distance);
        Vector3 position = rotation * negDistance + target.position;
        transform.rotation = rotation;
        transform.position = position;
    }
}
public static float ClampAngle(float angle, float min, float max)
{
    if (angle < -360F)
        angle += 360F;
    if (angle > 360F)
        angle -= 360F;
    return Mathf.Clamp(angle, min, max);
}
}

看起来您希望只在按住鼠标右键时才发生旋转。如果这是真的，那么将Input.GetMouseButton(1)从现在的位置移除，然后将其包裹在transform.rotation = rotation;周围。事情就是这么简单。仅供参考，你甚至不需要if (target)。这是不必要的，但我让它保持原样。

public Transform target;
public float distance = 5.0f;
public float xSpeed = 120.0f;
public float ySpeed = 120.0f;
public float yMinLimit = -20f;
public float yMaxLimit = 80f;
public float distanceMin = .5f;
public float distanceMax = 15f;
private Rigidbody rigidbody;
float x = 0.0f;
float y = 0.0f;
// Use this for initialization
void Start()
{
    Vector3 angles = transform.eulerAngles;
    x = angles.y;
    y = angles.x;
    rigidbody = GetComponent<Rigidbody>();
    // Make the rigid body not change rotation
    if (rigidbody != null)
    {
        rigidbody.freezeRotation = true;
    }
}
void LateUpdate()
{
    if (target)
    {
        x += Input.GetAxis("Mouse X") * xSpeed * distance * 0.02f;
        y -= Input.GetAxis("Mouse Y") * ySpeed * 0.02f;
        y = ClampAngle(y, yMinLimit, yMaxLimit);
        Quaternion rotation = Quaternion.Euler(y, x, 0);
        distance = Mathf.Clamp(distance - Input.GetAxis("Mouse ScrollWheel") * 5, distanceMin, distanceMax);
        RaycastHit hit;
        if (Physics.Linecast(target.position, transform.position, out hit))
        {
            distance -= hit.distance;
        }
        Vector3 negDistance = new Vector3(0.0f, 0.0f, -distance);
        Vector3 position = rotation * negDistance + target.position;
        //Move Input.GetMouseButton(1) here
        if (Input.GetMouseButton(1))
        {
            transform.rotation = rotation;
        }
        transform.position = position;
    }
}
public static float ClampAngle(float angle, float min, float max)
{
    if (angle < -360F)
        angle += 360F;
    if (angle > 360F)
        angle -= 360F;
    return Mathf.Clamp(angle, min, max);
}
