Question

以下是相机跟随的代码。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CameraTracker : MonoBehaviour {

public Transform target;
public float damping = 1;
public float lookAheadFactor = 3;
public float lookAheadReturnSpeed = 0.5f;
public float lookAheadMoveThreshold = 0.1f;

private float m_OffsetZ;
private Vector3 m_LastTargetPosition;
private Vector3 m_CurrentVelocity;
private Vector3 m_LookAheadPos;

[SerializeField]
private float xMax;
[SerializeField]
private float yMax;
[SerializeField]
private float xMin;
[SerializeField]
private float yMin;

// Use this for initialization
private void Start()
{
    target = GameObject.Find ("Player").transform;
    m_LastTargetPosition = target.position;
    m_OffsetZ = (transform.position - target.position).z;
    transform.parent = null;
}


// Update is called once per frame
private void Update()
{
    // only update lookahead pos if accelerating or changed direction
    float xMoveDelta = (target.position - m_LastTargetPosition).x;

    bool updateLookAheadTarget = Mathf.Abs(xMoveDelta) > lookAheadMoveThreshold;

    if (updateLookAheadTarget)
    {
        m_LookAheadPos = lookAheadFactor*Vector3.right*Mathf.Sign(xMoveDelta);
    }
    else
    {
        m_LookAheadPos = Vector3.MoveTowards(m_LookAheadPos, Vector3.zero, Time.deltaTime*lookAheadReturnSpeed);
    }

    Vector3 aheadTargetPos = target.position + m_LookAheadPos + Vector3.forward*m_OffsetZ;
    Vector3 newPos = Vector3.SmoothDamp(transform.position, aheadTargetPos, ref m_CurrentVelocity, damping);

    transform.position = newPos;

    m_LastTargetPosition = target.position;
}

void LateUpdate()
{
    transform.position = new Vector3(Mathf.Clamp(target.position.x,xMin,xMax), Mathf.Clamp(target.position.y,yMin,yMax), transform.position.z);

}
}

你如何让yMax没有钳位？另外，如何使yMin等于相机底部的位置，以便在相机向上移动时最小高度发生变化？

你如何让yMax没有钳位？

如果您不想约束Y的最大值，请使用Mathf.Max代替Mathf.Clamp：

Mathf.Max(target.position.y,yMin)

另外，如何让yMin等于相机底部的位置，以便在相机向上移动时最小高度发生变化？

yMin = Camera.main.transform.position.y;

因此，您生成的LateUpdate方法将是：

void LateUpdate()
{
    yMin = Camera.main.transform.position.y;

    transform.position = 
        new Vector3(Mathf.Clamp(target.position.x,xMin,xMax), 
            Mathf.Max(target.position.y, yMin), transform.position.z);
}

Unity将相机夹在相机的位置
