java - 定时器和loop()/noLoop()的问题

Question

我正在尝试在我的程序中编写一个函数，当单击鼠标时，该函数将暂停draw() 3 秒。当计时器经过 3 秒时，draw() 应该恢复，但事实并非如此。

Deck playerDeck;
Deck computerDeck;

PFont font;

int timer; //use this to allow cards to stay drawn for 2 or 3 seconds
int cardsLeft = 52;

**int savedTime;
int totalTime = 3000;** //milliseconds

void setup(){
  size(500,500);
  frameRate(30);
  playerDeck = new Deck(true,215,364,71,96);
  computerDeck = new Deck(false,215,40,71,96);
  font = loadFont("TimesNewRomanPSMT-20.vlw");
  textFont(font, 20);
  textAlign(CENTER);
  **savedTime = millis();**
}

void draw(){
  background(255);

  //draws the players' decks
  playerDeck.drawDeck();
  computerDeck.drawDeck();

  //informative text
  fill(0);
  text("Player",width/2,493);
  text("Computer",width/2,27);
  text(cardsLeft + " Cards left",width/2,height/2+5);
}

void mousePressed(){
  if(cardsLeft > 0){ //checks cards left aka clicks, limited to 52- size of deck
    if(playerDeck.deckClicked(mouseX,mouseY)){//checks if player deck is clicked
      println("You picked a card from your deck");
      playerDeck.drawCardAndCompare();//draws a random card for the player from a 2d array suit->card
      computerDeck.drawCardAndCompare();//draws a random card for the computer from a 2d array suit->card. 
      cardsLeft--;
    } else if(computerDeck.deckClicked(mouseX,mouseY)){//checks if the player clicked the computers deck. no need for computer interactivity so computer and player draws are simultaneous
      println("You can't take cards from the computer's deck!");
    } else {
      println("Click on your deck to pick a card");//if the player clicks elsewhere
    }
  } else {
    println("Game over"); //when cards left / clicks equals or is less then 0
  }
  **noLoop();**
}

**void mouseReleased(){
  int passedTime = millis() - savedTime;
  if(passedTime > totalTime){
    loop();
    savedTime = millis();
  }
}**

按下鼠标后，屏幕上会绘制一些图像。释放鼠标后，计时器应设置为 3 秒，三秒过后，它会激活 Loop() 来绘制图像。这里的问题是，按住鼠标按钮 3 秒然后释放将激活循环()，或者如果您在三秒之前释放鼠标按钮，则再次单击。如果我不清楚，我很抱歉，我现在真的很累，但需要完成这项工作。

当鼠标松开时，你可以让主线程 hibernate 3 秒。时间过后，它应该恢复。将您的事件处理程序更改为:

    @Override
    public void mouseReleased(MouseEvent e) {
        try {
            Thread.sleep(3000);
            //thread will then resume
        } catch (InterruptedException e1) {
            e1.printStackTrace();
        }   
    }
