Java 光滑的文本场不工作

我在使用Slick2D的文本字段时遇到问题

当使用Slick的“BasicGame”时，文本字段工作正常-我可以单击它，键入单词，然后在文本字段内容中键入System.out.printlin

但是，当在“BasicGameState”上使用相同的代码时，文本字段是不可单击的，不会响应任何输入

因此： 工作代码：

为方便起见：

这与BasicGameState是一致的——这就是Slick2D的工作原理——您现在可以复制粘贴代码了：p

package Help;
import org.newdawn.slick.AppGameContainer;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.SlickException;
import org.newdawn.slick.state.StateBasedGame;

public class Game extends StateBasedGame{

    public static final String gamename = "Problem!";
    public static final int TextFieldTestNum = 1;

    public Game(String gamename){
        super(gamename); 
        this.addState(new TextFieldTest(TextFieldTestNum));

    }
    public void initStatesList(GameContainer gc) throws SlickException{
        this.getState(TextFieldTestNum).init(gc, this);
        this.enterState(TextFieldTestNum); //The First state to enter
    }

    @Override
    public boolean closeRequested(){
        System.exit(0);
        return false;
    }

    public static void main(String[] args) {
        AppGameContainer appgc;
        try{
            Game g = new Game(gamename);
            appgc = new AppGameContainer(g);
            appgc.setDisplayMode(500, 500, false);
            appgc.start();
        }catch(SlickException e){
            e.printStackTrace();
        }
    }
}

任何想法都值得赞赏

你的问题是如何在slick中进行基于州的游戏。如果您在此处引用我的wiki条目：

您会注意到，在initStatesList（）方法中，我只使用这个.addState（new StateName（））。这是因为addState（）方法的作用。它为您调用init方法，因此不需要在顶级应用程序类（在您的示例中是Game.java）中执行getState（）或enterState（）

要总结如何解决问题，请删除initStatesList（）方法中的所有内容， 然后移动这个.addState（newtextfieldtest（TextFieldTestNum））； 从主构造函数到initStatesList（）方法

一旦我在你的程序中纠正了这一点，它对我来说运行得很好
