Unity例程

1.实现敌人视线慢慢转向玩家

public class API_3_lookr : MonoBehaviour {
   

    public Transform emeny;
    public Transform player;

	// Use this for initialization
	void Start () {
   
		
	}
	
	// Update is called once per frame
	void Update () {
   
		//指向player的向量
        Vector3 direct = emeny.position - player.position;
        direct.y = 0;
        //将向量转换为quaternion，看的rotation
        Quaternion target = Quaternion.LookRotation(direct);
        //emeny慢慢转向player
        emeny.rotation = Quaternion.Slerp(emeny.rotation, target, Time.deltaTime);
	}
}

2.实现氮气加速效果

Rigidbody.AddForce(transform.forward * size);

3.鼠标碰撞检测

public class API_4_raydect : MonoBehaviour {
   

    private Camera camera1;

	// Use this for initialization
	void Start () {
   
		//获得第一个camera tagged "MainCamera"
        camera1 = Camera.main;
	}
	
	// Update is called once per frame
	void Update () {
   
		//将鼠标位置转化为ray
        Ray ray = camera1.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;
        bool isCollider = Physics.Raycast(ray, out hit);
        if (isCollider)
        {
   
            Debug.Log(hit.collider);
        }
	}
}

4.射线碰撞RayCast
