Java Swing energybar 未更新

Question

想知道你们是否可以帮助我解决这个问题:

我有一个具有以下方法的 UIMain 类。每当我在主方法中调用所有 3 个计时器时，我的计时器似乎都不起作用

setupEnergyBar();
setupDeductingEnergyBar();
updateData();

public void setupEnergyBar(){
    energyBar = new JProgressBar();
    energyBar.setStringPainted(true);
    energyBar.setMinimum(0);
    energyBar.setMaximum(100);
    setupDeductingEnergyBar();
}

public void setupDeductingEnergyBar(){
    energyDeductTimer = new Timer(1000, new ActionListener(){
        public void actionPerformed(ActionEvent e) {
            character.setCharEnergyLvl(character.getCharEnergyLvl() - 5);
    }
    });
    energyDeductTimer.start();
    updateData();

}

public void updateData(){
        character.getCharName();
        character.getCharEnergyLvl();
        energyBar.setValue(character.getCharEnergyLvl());
//          setCharStatus();
//          setCharActionLvl(getCharActionLvl());
//          setCharEnergyLvl(getCharEnergyLvl());
//          setCoins(getCoins());
//          setHero(isHero());
//          setCrimesFought(getCrimesFought());
//          setCrimesCommited(getCrimesCommited());
//          setCrimesIgnored(getCrimesIgnored());
//          
    }
}

非常感谢

您的问题出在 setupDeductingEnergyBar 方法中。您正在创建一个计时器，并更新角色能量，但您没有更新进度条。修复方法只是将 updateData 方法移至 energyDeductTimer 的操作监听器中。
