Unity第一人稱和第三人稱視角

第一人稱視角

public class FirstView : MonoBehaviour
{
    //要相機跟隨的GameObject
    public Transform m_target;
    //滑鼠敏度  
    public float mousesSensity = 10F;

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

    Vector3 m_camRotation;
    void Update()
    {
        //根據滑鼠的移動,獲取相機旋轉的角度

        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);

        //相機角度隨著滑鼠旋轉  
        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:攝像機新增改指令碼 target:要相機跟隨的GameObject(主角Player) minYLimit方向最小視角
minXLimit方向最大視角
mousesSensity:水平方向和垂直方向滑鼠移動速度
