如何优化多个if-else语句AS3？

Question

因此，我有函数characterBooleanFunction，该函数包含30多个if-else语句。当我运行Scout来检查性能时，它指向该函数，该函数也是由ENTER_FRAME事件运行的。侦察员向我显示gotoAndStop语句的成本很高。我不确定每次我运行游戏时都会如何解决，这简直太糟糕了。用户滚动屏幕上的字符，当它们打到一个标记时，它将激活characterBooleanFunction功能。有任何想法吗？这是代码：

private function characterBooleanFunction():void 
    {
        if (scrollCharacters.mcRandom.hit.hitTestObject(storeScreen.mcMarker) )
       {
           scrollCharacters.mcRandom.gotoAndStop(2);

           //booleans
           bRandom = true;

       }else
       {
           scrollCharacters.mcRandom.gotoAndStop(1);
           bRandom = false;
       }

       if (scrollCharacters.mcChinese.hit.hitTestObject(storeScreen.mcMarker) )
       {
           scrollCharacters.mcChinese.gotoAndStop(2);
           trace("HIT CHINESE");
            //booleans
           bChinese = true;

       }else
       {
           scrollCharacters.mcChinese.gotoAndStop(1);
           bChinese = false;
       }

       if (scrollCharacters.mcPizza.hit.hitTestObject(storeScreen.mcMarker) )
       {
           scrollCharacters.mcPizza.gotoAndStop(2);
           trace("HIT PIZZA");
            //booleans

           bPizza = true;

       }else
       {
           scrollCharacters.mcPizza.gotoAndStop(1);
           bPizza = false;
       }

       if (scrollCharacters.mcBurger.hit.hitTestObject(storeScreen.mcMarker) )
       {
           scrollCharacters.mcBurger.gotoAndStop(2);

            //booleans
           bBurger = true;

       }else
       {
           scrollCharacters.mcBurger.gotoAndStop(1);
           bBurger = false;
       }

...等等。

谢谢！
