这里需要一些帮助。我总是收到这个错误:

这是我的类(class):
package com.rs.game.player.content;
import com.rs.game.player.Player;
public class DungeoneeringShop {
private static final int INTERFACE_ID = 72;
public static Player player;
public static void open() {
for(int i = 69; i < 73; i++)
player.getPackets().sendHideIComponent(INTERFACE_ID, i, false);
player.getInterfaceManager().sendInterface(INTERFACE_ID);
}
}
最佳答案
您还没有初始化播放器。所以它是null。
好像是
null.getPackets() --------------> NullPointerException
所以分辨率是在使用之前初始化它
public static Player player = new Player(); // at declaration level
或
player = new Player(); // or later some where before using.
