Question

我的代码打开一个窗口，其中显示了类似Rpg的项目的统计信息，这是随机生成的，现在我的问题是，我不知道如何制作它所以它按下后生成一个新项目按钮。我正在使用libgdx框架。在编码时，我是一个血腥的新手，这几乎是我的第一个应用程序。这是我的代码：

正如你自己所说，你是一个新秀。所以一些提示是有序的。确保你带相关的变量并将它们分成如下类：

public class Item
{
    int prefixIndex;
    int nameIndex;
    int typeIndex;
    int itemLevel;
    int damage;
    int weaponSpeed;
    int weaponStrengh;
    int weaponEndurance;
    int weaponCritical;
    int weaponWisdom;

    String [] Prefix = {"Blunt", "Sharp", "Jagged", "Grandmaster's", 
"Knight's", "Apprentice's","Crude", "Godly", "Flawless", "Barbaric", 
"Horrific", "Hiddeous", "Demonic", "Dull", "Bloody", "Holy", "Engergiced", 
"Fast", "Otherworldly", "Well-Worn", "Elegant","Vigilant", "Surpressing" 
,"Destroying", "Vampiric", "Intimidating"};
String [] Name = {" Soulsplitter"," Axe", " Sword", " Spear", " Bow", " 
Longbow", " Staff", " God Eater", " Doomsday Device", " Excalibur", " 
Nature's Call", " Forest Spirit", " Dragon's Breath", " God's Wrath", " 
Buster", " Peace Keeper", " Jackhammer", " Battleaxe", " Emperor's Lance", " 
Tsunami", " Hurricane"};
String [] ItemType = {"Axe", "Sword", "Broadsword", "Dagger", 
"Bow","Longbow","Staff","Spear","Hammer"};

    public Item(int prefixIndex, int nameIndex, int typeIndex)
    {
        this.prefixIndex = prefixIndex;
        this.nameIndex = nameIndex;
        this.typeIndex = typeIndex;
    }

public int getPrefixIndex()
{
    return prefixIndex;
}

public void setPrefixIndex(int prefixIndex)
{
    this.prefixIndex = prefixIndex;
}

public int getNameIndex()
{
    return nameIndex;
}

public void setNameIndex(int nameIndex)
{
    this.nameIndex = nameIndex;
}

public int getTypeIndex()
{
    return typeIndex;
}

public void setTypeIndex(int typeIndex)
{
    this.typeIndex = typeIndex;
}

public int getItemLevel()
{
    return itemLevel;
}

public void setItemLevel(int itemLevel)
{
    this.itemLevel = itemLevel;
}

public int getDamage()
{
    return damage;
}

public void setDamage(int damage)
{
    this.damage = damage;
}

public int getWeaponSpeed()
{
    return weaponSpeed;
}

public void setWeaponSpeed(int weaponSpeed)
{
    this.weaponSpeed = weaponSpeed;
}

public int getWeaponStrengh()
{
    return weaponStrengh;
}

public void setWeaponStrengh(int weaponStrengh)
{
    this.weaponStrengh = weaponStrengh;
}

public int getWeaponEndurance()
{
    return weaponEndurance;
}

public void setWeaponEndurance(int weaponEndurance)
{
    this.weaponEndurance = weaponEndurance;
}

public int getWeaponCritical()
{
    return weaponCritical;
}

public void setWeaponCritical(int weaponCritical)
{
    this.weaponCritical = weaponCritical;
}

public int getWeaponWisdom()
{
    return weaponWisdom;
}

public void setWeaponWisdom(int weaponWisdom)
{
    this.weaponWisdom = weaponWisdom;
}
}

我个人会在这个类中加入一些变量并将它们进一步分开，以便类不那么大。但这可能会让你在你的水平上迷惑。但是使用这个类我可以像这样重写你的代码：

哦，我也不知道libgdx是如何工作的，所以你需要了解你的框架，知道实际放置这段代码的位置：

public Item generateItem()
{
    Random random = new Random(System.nanoTime());
    int prefix = random.nextInt(Item.Prefix.length);
    int name = random.nextInt(Item.Name.length);
    int type = random.nextInt(Item.ItemType.length);

    temp.setItemLevel(random.nextInt(1000));
    temp.setDamage(random.nextInt(25000));
    temp.setWeaponSpeed(random.nextInt(100));
    temp.setWeaponStrengh(random.nextInt(350));
    temp.setWeaponEndurance(random.nextInt(350));
    temp.setWeaponWisdom(random.nextInt(350));
    temp.setWeaponCritical(random.nextInt(350));
}

然后有一个实例变量Item generatedItem，只要你需要一个新变量，只需拨打generatedItem = generateItem();

我也注意到你的骆驼外壳不一致。有些领域的开头是像Damage这样的大写字母，有些则没有。它有助于提高可读性，一般的良好做法是变量/字段以小写字母开头。方法也一样，它们通常应该是get和generate之类的动词。

要尽我所能回答您的问题，您需要找到按下按钮时调用的方法。在该方法中生成一个项目，并确保渲染器具有对新项目的引用。

只要您想通过随机数更改值，请致电generateRandom()。

 public class XYZ extends ApplicationAdapter {

            batch = new SpriteBatch();
            font = new BitmapFont();

            random=new Random();
