如何编写检查数组索引的 if 语句？

我有一个名为 setMonster() 的方法，位于名为“main”的包中名为“AssetSetter”的类中，它根据来自名为“MON_GreenSlime”的不同包的另一个类中的信息创建新的怪物。

AssetSetter 类内部的 SetMonster() 看起来像这样（实际上列表要长得多，但你得到了夹具）：

public void setMonster(){

        gp.monster[0] = new MON_GreenSlime(gp);
        gp.monster[0].worldX = gp.tileSize * 26;
        gp.monster[0].worldY = gp.tileSize * 20;

        gp.monster[1] = new MON_GreenSlime(gp);
        gp.monster[1].worldX = gp.tileSize * 22;
        gp.monster[1].worldY = gp.tileSize * 18;

        gp.monster[2] = new MON_GreenSlime(gp);
        gp.monster[2].worldX = gp.tileSize * 24;
        gp.monster[2].worldY = gp.tileSize * 17;

    }

因此，在 MON_GreenSlime 类内部，我有一个名为 setAction() 的方法，它将 AI 移动设置为怪物。在这个 setAction() 内部，我想做一个 if 语句，检查 m 中 gp.monster[] 的索引作为其条件。沿着这个思路的东西（如果这可行的话）

if (gp.monster[index] index == 0){
  //do something
} 

else if (gp.monster[index] index == 1){
  //do something
}

//And so on... (The index is just as an example) Like I explained, I don't know how I would write such an if statement

单个怪物的AI移动是由它的默认x和y位置控制的，因此当我创建超过1个怪物时，我觉得我需要某种if或switch语句来处理每个怪物单独的数组索引。

如果您知道一个简单的解决方案，请告诉我:)我对 Java 还很陌生，所以如果它很明显，请对我宽容一些

原文

I have this method called setMonster(), in a class called 'AssetSetter' in a package called 'main', which creates new monsters based on information in another class from a different package called 'MON_GreenSlime'.

SetMonster() inside of the AssetSetter class looks like this(the list is much longer in reality but you get the jig):

public void setMonster(){

        gp.monster[0] = new MON_GreenSlime(gp);
        gp.monster[0].worldX = gp.tileSize * 26;
        gp.monster[0].worldY = gp.tileSize * 20;

        gp.monster[1] = new MON_GreenSlime(gp);
        gp.monster[1].worldX = gp.tileSize * 22;
        gp.monster[1].worldY = gp.tileSize * 18;

        gp.monster[2] = new MON_GreenSlime(gp);
        gp.monster[2].worldX = gp.tileSize * 24;
        gp.monster[2].worldY = gp.tileSize * 17;

    }

So inside of the MON_GreenSlime class I have a method called setAction() which sets AI movement to the monster. Inside this setAction() I want to make an if statement that checks the index of the gp.monster[] from the m as its condition. Something along the lines of this(if this would work)

if (gp.monster[index] index == 0){
  //do something
} 

else if (gp.monster[index] index == 1){
  //do something
}

//And so on... (The index is just as an example) Like I explained, I don't know how I would write such an if statement

The individual monsters AI movement is controlled by it's default x and y location, therefore when I create more than 1 monster I feel like I need some sort of if or switch statement to treat each array index individually.

Someone please let me know if you know of a simple solution :) I'm pretty new to Java, so go easy on me if its obvious
