Question

我对LibGDX有疑问。这是空白项目女巫只使用套接字连接到其他程序。当我尝试启动它时，它只是挂起程序没有响应。套接字连接已建立并正常工作。谢谢你的帮助~BeefEX

package com.beefcodes.game;
import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;

public class MyGdxGame extends ApplicationAdapter {

    SpriteBatch batch;
    BitmapFont font;

    String lastMsg = "test";

    Socket socket;
    PrintWriter output;
    BufferedReader input;

    @Override
    public void create () {
        batch = new SpriteBatch();
        font = new BitmapFont();
        try {
            socket = new Socket("localhost", 540);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }


    public void render () {
        if (input == null && output == null) {
            try {
                output = new PrintWriter(socket.getOutputStream(), true);
                input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();
        String s;
        try {
            if ((s = input.readLine()) != null)
                lastMsg = s;
        } catch (IOException e) {
            e.printStackTrace();
        }
        font.draw(batch, lastMsg, 100, 100);
        batch.end();
    }
}

从渲染方法

中删除它

 if (input == null && output == null) {
        try {
            output = new PrintWriter(socket.getOutputStream(), true);
            input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

您不希望每秒创建60个PrintWriters和60个BufferedReaders。此外，我甚至没有看到这些被使用的地方。在任何情况下，也许这可以在create方法中完成一次。

LibGDX渲染未调用
