Question

我差不多已经完成了我的项目，但是当我尝试加载我的库中的影片剪辑时，我的分数达到100，它会从舞台上移除游戏，但不会显示我正在尝试的屏幕显示。

我写的代码如下。非常感谢任何帮助。

    package

        //will be used to collect the chocolate bars.
        var catcher:Catcher;
        var nextObject:Timer;
        var objects:Array = new Array();
        var score:int = 0;
        const speed:Number = 7.0;
        //end of catcher code

        //beginning of game code - spawns a new catcher on screen
        //at start of game.

                    {
                        score +=  10;
                    }
                    else
                    //decrease score if catcher catches "Bad" object.
                    {
                        score -=  5;
                    }
                    //prevents score from going below 0
                    if (score < 0)
                    {
                        score = 0;
                    }
                    scoreDisplay.text = "Score: " + score;
                    //once object hits catcher, remove object from                                                                                              stage.
                    removeChild(objects[i]);
                    objects.splice(i,1);
                }
                //if statement to move screen to promotion screen
                //once score reaches past 100
//THIS IS WHERE I THINK THE ISSUE IS!!!
            if(score >= 100) {
                var promotionScreen:promotion = new promotion;
                //stage.removeChild(this)
                addChild(promotionScreen);
                removeEventListener(Event.ENTER_FRAME, moveObjects);
                promotionScreen = stage.stageWidth / 2;
                promotionScreen = stage.stageHeight /2;


            }
            //end of if statement
            }






            //sets catcher to work with mouse movement.
            catcher.x = mouseX;

        }
    }
}

Answer 1

您应该在if(score >= 100)的末尾设置中断，因为这种情况可以在您的for循环中启动几次。您的MovieClip也可以停止，请尝试.play()或.gotoAndStop() 哦!并设置promotionScreen = stage.stageWidth/2，promotionScreen.x = stage.stageWidth/2

分数达到一定数量后加载到影片剪辑中
