在 FSM 中设置状态
我第一次使用基于类的 FSM，我对设置初始状态的最佳实践有点困惑。
我已将 FSM 添加到我的 Screen 类中，我想用它来处理（大部分）转换。传统上我会做这样的事情：
function update(frameTime : Number) : void
{
switch(_currentState)
{
case STATE_TRANSITIONING_IN:
slideTheButtonsIn();
if(buttonsInPlace == true)
changeState(STATE_ACTIVE);
break;
case STATE_ACTIVE:
if(buttonClicked() == true)
changeState(STATE_TRANSITIONING_OUT)
break;
case STATE_TRANSITIONING_OUT:
slideButtonsOut();
if(buttonsInPlace == true)
removeThisScreen();
break;
}
}
我认为这是一个非常标准的方法。
所以我的新状态的问题是，谁负责创建屏幕上的所有对象？我的 Screen 应该创建所有按钮和内容，然后将它们传递给 MainMenuTransitionInState 类，还是 MainMenuTransitionState 类创建按钮然后传递它们还是我完全错过了目标？
在这里感谢您的明智建议。谢谢！
I'm using an class based FSM for the first time and I'm a little confused on what the best practice is to set-up the initial state.
I've added a FSM to my Screen class that I want to use to handle (mostly) transitions. Traditionally I'd do something like this:
function update(frameTime : Number) : void
{
switch(_currentState)
{
case STATE_TRANSITIONING_IN:
slideTheButtonsIn();
if(buttonsInPlace == true)
changeState(STATE_ACTIVE);
break;
case STATE_ACTIVE:
if(buttonClicked() == true)
changeState(STATE_TRANSITIONING_OUT)
break;
case STATE_TRANSITIONING_OUT:
slideButtonsOut();
if(buttonsInPlace == true)
removeThisScreen();
break;
}
}
I think that's a pretty standard approach.
So my problem with my new states are, WHO is responsible for creating all the objects on screen? Should my Screen create all the buttons and stuff and then pass them to the MainMenuTransitionInState class or should the MainMenuTransitionState class create the buttons and then pass them around or have I missed the mark entirely?
Appreciate your sage advice here. Thanks!

模型-视图-控制器模式可能会有所帮助这里。
MainMenuScreen（视图）这将显示您的模型。在这里处理所有与 UI 相关的对象。直接查询模型以初始化或更新它们。
MainMenuFsm（控制器）这是视图的事件处理程序。每当用户与您的视图交互时，请将操作转换为模型的更新。
MainMenuState（模型）在此处存储您的状态。
A model-view-controller pattern might help here.
MainMenuScreen(View)This is what will display your model. Work with all your UI related objects here. Query the model directly to initialize or update them.
MainMenuFsm(Controller)This is your view's event handler. Whenever the user interacts with your view, translate the actions into updates to your model.
MainMenuState(Model)Store your state here.
