平台游戏。下一帧跳转到下一级

Question

我为 android 设备创建了一个具有 20 个级别的平台游戏。每个级别都有不同的步行平台和具有不同属性的新敌人。我的第一帧有 20 个按钮，第一个按钮转到第一级（第 2 帧），第二个按钮转到第二级（第 3 帧），一直持续到第 21 帧的最后一级。我在第 2 帧（第 1 级）玩家移动、敌人属性、硬币、生命等中编写了我所有的代码。当玩家死亡或玩家完成阶段时，我进入第 1 帧并准备好单击“2 级”按钮，进入第 3 帧的第二阶段。那么，我的代码的哪一部分必须转移到二级？

这是我在第二帧中的部分代码。（我只展示了一个敌人（medouza）和我移动玩家的控件，因为是一个大代码）

我只想将所有游戏代码放在第 1 帧上。

还在第 1 帧上制作一个名为 levelsMC 的新 MovieClip，它是所有关卡帧的容器（使用舞台时间轴中的 "cut frames" 并将它们粘贴到关卡 MC 中时间轴），

现在您的代码可以只说 2 级 = levelsMC.gotoAndStop(2); 或 3 级 levelsMC.gotoAndStop(3);...

因为 code 和 levelsMC 都在第 1 帧上，所以您不必传输（重新复制）任何代码。

你的工作逻辑是：

I have the first frame with one button ( levelButton ),

I have a variable nextLevel (integer) that has frame number. I update as nextLevel = 2;

The first button tells levelsMC go to first level (using levelsMC.gotoAndStop(2);) or can use levelsMC.gotoAndStop(nextLevel);

the second button go to second level (using levelsMC.gotoAndStop(3);)

and goes on until the final level in frame 21 (levelsMC.gotoAndStop(21);).

I write all of my code in frame 1 and to show from level 1 onwards I say :
startScreenMC.visible = false; and levelsMC.visible = true;

When the player complete the stage I update nextLevel number (integer) as +1 and i'm ready to click to levelButton, where click/tap function simply tells levelsMC to got frame x (where x is nextLevel amount) like this :
levelsMC.gotoAndStop( nextLevel );

PS：查看 AS3 linkage 教程。使创建硬币或字符的 MC 变得更容易，并且在需要时只需 addChild 到 levelsMC。然后代码通过 levelsMC.coin = visible = false; 等路径访问它
