吉里吉里TJS特訓99

特訓99是數年前在巴哈姆特kuso版看到的一個遊戲，規則很簡單：「閃避畫面上的99顆子彈，看你可以撐幾秒」自從看到了這個遊戲之後，每到一個可以寫遊戲的環境，我都把他當hello, world來寫了，幫助熟悉整個程式環境。(印像中寫過C++/DirectDraw, J2SE, J2ME on 手機, VisualBasic, Ruby/RPG Maker XP還有什麼忘了)

剛剛把試著用吉里吉里的TJS寫了一下，心得…喵的文件有夠不完整，要到處翻來翻趣，有的地方乾脆去template裡直接看他怎麼寫的比較快。寫出來就這樣囉：

不停的閃子彈閃到死吧 XD

其實code寫的很差，我只是一直翻文件然後找出一個能寫出來的方法而已。很多地方應該可以再修正的。碰撞判定的公式其實也是錯的，可是我懶得改了，可以跑就好了啦，只是做個小範例而已 @@
為了簡化範例，被擊中game over時就直接跳出遊戲了 (好我懶得做game over畫面了 XD)
為了簡化範例所以沒有貼圖，都是用方塊表示。這樣只需要把程式複置貼上就可以跑囉

把以下程式複置貼到startup.tjs (原本的程式清掉) 即可


class MovingObject extends Layer{
  var master;
  var size;
  var color;
  
  function MovingObject(gm, window, parent) {
    super.Layer(window, parent);
    master = gm;

    fillRect(0, 0, size, size, color);
  }
}

  }
  
}

  function GameWindow() {

    super.Window();
    
    add(new Layer(this, null));
    primaryLayer.setSize(400, 400);

  }
  function finalize() {
    super.finalize();
  }
 function action(ev) { }

var win = new GameWindow();

解說篇….下次再說吧 XD
