Unity第一人称和第三人称视角

第一人称视角

public class FirstView : MonoBehaviour
{
//要相机跟随的GameObject
public Transform m_target;
//鼠标敏度
public float mousesSensity = 10F;

//上下最大视角(Y视角)
public float minYLimit = -20F;
public float maxYLimit = 80F;

Vector3 m_camRotation;
void Update()
{
//根据鼠标的移动,获取相机旋转的角度

m_camRotation.x = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * mousesSensity;

m_camRotation.y += Input.GetAxis("Mouse Y") * mousesSensity;
//角度限制
m_camRotation.y = Mathf.Clamp(m_camRotation.y, minYLimit, maxYLimit);

//相机角度随着鼠标旋转
transform.localEulerAngles = new Vector3(-m_camRotation.y, m_camRotation.x, 0);
transform.position = m_target.position;
}

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

使用方法:摄像机添加改脚本
target:要相机跟随的GameObject(主角Player)
minYLimit方向最小视角

minXLimit方向最大视角

mousesSensity:水平方向和垂直方向鼠标移动速度
