Minecraft 插件玩家名称错误

Question

我正在写类似 SRM 的东西，在服务器重置之前一切都很好。当我写一个标志并试图购买它（分配给标志的区域）时，它应该向我发送一条我不能的消息，它确实如此，但在服务器重置后它没有，并且在这两种情况下变量都是一样...这是我的代码：

    }

}

和控制台 returns 只有这个：

[12:27:42] [Server thread/INFO]: [0;35;1m[Server[0;35;1m] stan:1000.0[m

[12:28:17] [Server thread/INFO]: [0;31;1mPlease specify the world with -w world_name.[m

我知道我没有为 rg addowner 和 removeovner 指定 world，但事实并非如此，日志中也没有更多错误...请帮助我。

Answer 1

当我改变

if(event.getPlayer().getName() == sign.getLine(1)){

至

RegionContainer container = getWorldGuard().getRegionContainer();
RegionManager regions = container.get(player.getWorld());
if(regions != null){
  ProtectedRegion region = regions.getRegion(sign.getLine(3));
  DefaultDomain owners = region.getOwners();
if(owners.contains(player.getUniqueId())){

它按预期运行。

Answer 2

您需要比较字符串而不是检查对象是否相等。 string1.equals(string2)/string1.equalsIgnoreCase(string2) 比较字符串而 string1 == string2 不比较。

你可以试试这个：

if (event.getPlayer().getName().equals(sign.getLine(1)))

或者如果您不想区分大小写

if (event.getPlayer().getName().equalsIgnoreCase(sign.getLine(1)))
