本文介绍了一个简单实用的Unity摄像机跟随脚本，适用于第三人称视角游戏。该脚本可实现平滑跟随目标物体，并带有碰撞检测功能，避免摄像机穿模。

很简单的第三人称摄像机跟随控制脚本，直接挂在摄像机的对象上就可以用了。
public class SmoothCameraWithBumper : MonoBehaviour
{
public Transform target = null; //Was: [SerializeField] private Transform target = null;
[SerializeField] private float distance = 3.0f;
[SerializeField] private float height = 1.0f;
[SerializeField] private float damping = 5.0f;
[SerializeField] private bool smoothRotation = true;
[SerializeField] private float rotationDamping = 10.0f;

[SerializeField] private Vector3 targetLookAtOffset = Vector3.zero

[SerializeField] private float bumperDistanceCheck = 2.5f;
[SerializeField] private float bumperCameraHeight = 1.0f;
[SerializeField] private Vector3 bumperRayOffset = Vector3.zero;

public Quaternion adjustQuaternion { get; set; }
private Quaternion originalRotation;

private void Awake()
{
         UnityEngine.Camera myCamera = GetComponent<UnityEngine.Camera>(); // Use GetComponent() for Unity 5 compatibility.
if (myCamera != null) myCamera.transform.parent = target;
adjustQuaternion = Quaternion.identity;
}

private void Start()
{
originalRotation = transform.localRotation;
}

private void FixedUpdate()
{
Vector3 wantedPosition = target.TransformPoint(0, height, -distance);


RaycastHit hit;
Vector3 back = target.transform.TransformDirection(-1 * Vector3.forward);


if (Physics.Raycast(target.TransformPoint(bumperRayOffset), back, out hit, bumperDistanceCheck)
      && hit.transform != target) // ignore ray-casts that hit the user. DR
{

wantedPosition.x = hit.point.x;
wantedPosition.z = hit.point.z;
wantedPosition.y = Mathf.Lerp(hit.point.y + bumperCameraHeight, wantedPosition.y, Time.deltaTime * damping);
}

transform.position = Vector3.Lerp(transform.position, wantedPosition, Time.deltaTime * damping);

Vector3 lookPosition = target.TransformPoint(targetLookAtOffset);

if (smoothRotation)
{
Quaternion wantedRotation = Quaternion.LookRotation(lookPosition - transform.position, target.up);
transform.rotation = Quaternion.Slerp(transform.rotation, wantedRotation, Time.deltaTime * rotationDamping);
}
else

}

transform.localRotation = originalRotation * adjustQuaternion;
}

}
