如何将局部变量更改为全局变量？

Question

因此，我正在编辑游戏的源代码，并且有一个事件可以读取游戏的聊天记录。 我需要游戏来阅读聊天，从聊天中复制一些单词，使用第一个单词输入聊天消息，稍等片刻，使用第二个单词输入聊天消息等。现在，代码如下所示：

private final long PERIOD = 4000L; //timer
private long lastTime = System.currentTimeMillis() - PERIOD; 
@SubscribeEvent
    public void onChat(final ClientChatReceivedEvent e) { //look at the chat
        final String chat = e.message.getUnformattedText(); 
          if(chat.startsWith("Something")) { //if the chat message starts with "Something"
                //Create the string chatp1 being "Something 123"
                String click = chatp1.replace("Something ", ""); //Creates a string "click", which is chatp1 without the "Something ", so it's "123"
//After it basically does the same thing multiple times, but instead of "Something" it's "Something1" and instead of "123" it's "124" etc.
//Then I need to run the commands
MyGame.getMyGame().thePlayer.sendChatMessage("/Command " + click); //runs the command "/Command 123"
          long thisTime12 = System.currentTimeMillis();
            if ((thisTime12 - lastTime) >= PERIOD) { //waits
                    lastTime = thisTime12;
MyGame.getMyGame().thePlayer.sendChatMessage("/Command " + click2); //Runs the command "/Command 124"
//etc.

现在有一个问题：找不到“ click”和“ click2”，这很明显：它们是局部变量，而不是全局变量。 我的问题是：更改代码以使在代码中可以找到“ click”和“ click2”的最简单方法是什么？ 我是否应该在一开始就将它们声明为全局变量（如果是，如何？）或其他？

Answer 1

将其声明移至类中，以便它们成为字段。

Answer 2

这是答案：

private final long PERIOD = 4000L; //timer
private long lastTime = System.currentTimeMillis() - PERIOD; 
String click = "";
String click2 = "";
@SubscribeEvent
    public void onChat(final ClientChatReceivedEvent e) { //look at the chat
        final String chat = e.message.getUnformattedText(); 
          if(chat.startsWith("Something")) { //if the chat message starts with "Something"
                //Create the string chatp1 being "Something 123"
                click = chatp1.replace("Something ", ""); //Creates a string "click", which is chatp1 without the "Something ", so it's "123"
//After it basically does the same thing multiple times, but instead of "Something" it's "Something1" and instead of "123" it's "124" etc.
//Then I need to run the commands
MyGame.getMyGame().thePlayer.sendChatMessage("/Command " + click); //runs the command "/Command 123"
          long thisTime12 = System.currentTimeMillis();
            if ((thisTime12 - lastTime) >= PERIOD) { //waits
                    lastTime = thisTime12;
MyGame.getMyGame().thePlayer.sendChatMessage("/Command " + click2); //Runs the command "/Command 124"
//etc.
