Unity3d工具方法小集

获取垂直水平方向上的输入：

float moveHorizontal = Input.GetAxis("Horizontal");
float moveVertical = Input.GetAxis("Vertical");

给刚体一个力：

Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
GetComponent<Rigidbody>().AddForce(movement * speed * Time.deltaTime);

摄像头45度俯视角：

Camera:

Position:  x(0)   y(5)    z(-6)

Rotate:    x(45)  y(0)    z(0)

Scale:     x(1)   y(1)    z(1)

摄像机跟随：

public GameObject player;
private Vector3 offset;

// Use this for initialization
void Start () {
    //摄像机与跟随物体的初始相对位置
    offset = transform.position - player.transform.position;
}

// Update is called once per frame
void LateUpdate () {
    //跟随物体的位置加上相对位置
    transform.position = player.transform.position + offset;
}
