通过串行连接到 arduino 的 minecraft 插件
minecraft plugin to arduino over a serial connection
我正在尝试使用命令 /arduino 从 minecraft 通过 COM4 发送消息
（我的arduino所在的端口）消息必须是“allesfade”
我只用了 java 但在 minecraft 中不行。
这是我的代码（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;
}
}
这是我在 java 中编写的有效代码。

有趣的项目:)
我会说问题是它是一个插件。插件在服务器上运行，而不是在客户端运行。所以你需要将 arduino 连接到服务器。如果你想从我的世界控制一个arduino，你需要一个mod（在客户端运行）用于我的世界。
IDK 如果那行得通。
另一种方法是将 arduino 连接到互联网（Shield，或使用 Raspberry pi），然后让插件（在服务器上运行）向 shield/pi 发送消息通过互联网。
抱歉英语不好:(
希望对您有所帮助:)
