這是個小遊戲,最早出現在某個頁遊平臺,玩法簡單,先上圖:

遊戲主要分為3各部分, 1.小球旋轉(這個太簡單了,只有幾句程式碼); 2. 生成併發射 針(我反正覺得像針); 3.檢測發射結果(加分或者失敗)

基本上沒有什麼難點,主要是檢測碰撞的針頭一定要綁碰撞器和剛體,用2D的就行了, 剛體記得要把重力設為0,不然針頭會往下掉;

針頭的tag可以新建一個 "Head",方便識別,或者就用已有的也行

程式碼有2個指令碼,HeadCheck是綁在針頭上的,另外一個放在最上層節點即可;所有Public物件是手動繫結的

using UnityEngine;
using System.Collections;

public class HeadCheck : MonoBehaviour 
{
    public EveryBitOfTime _GameRoot;

    //碰撞檢測,需要繫結碰撞器(Collider2D)和 rigidbody2D
    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.tag == "Head")
        {
            Debug.Log("GG");
            _GameRoot.IsGameOver = true;
        }

    }
}
