我想通過命令/ arduino發送來自我的世界的COM4的消息 (我的arduino所在的端口)消息必須是「allesfade」 我得到了它的工作只有java而不是我的世界。通過串口連接到arduino的minecraft插件
這裏是我的代碼(不工作)
package me.PixelHamster.idk;
import java.io.IOException;
import java.io.PrintWriter;
import javax.comm.SerialPort;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin {
static SerialPort basispoort;
public void onEnable() {
System.out.println("suc6vol aangezet :3");
}
public void onDisable() {
System.out.println("sec6vol afgezet :3");
}
public boolean onCommand(CommandSender zender, Command cmd, String label, String[] argument) {
if (cmd.getName().equalsIgnoreCase("arduino")) {
try {
PrintWriter output = new PrintWriter(basispoort.getOutputStream());
output.print("allesfade");
output.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
return true;
}
}
這裏是代碼只是在Java中,我寫了工作。

好,但我嘗試使它的第一部作品只是在本地服務器上 – ToxicMushroom
然後它可以工作,但心不是在它應該的方式。 –
