所以我想检查一下,当玩家在第一次执行命令后,手里拿着一本书时,他们会向右点击。我试着让Runnable作为定时器运行,并在调度程序中检查玩家是否在手中拿着一本书右键单击。Runnable迫使我重写“run”方法。
这就是我尝试过的:
@Override
public void onEnable() {
this.getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable() {
@Override
public void run() {
//Here I want to check if the player right clicked with a book in their hand.
}

为了知道玩家是否运行了命令,您必须将播放器的UUID存储在某个地方。首先,创建一个Set<UUID>,它临时存储执行命令的所有玩家的所有唯一ID,所以当您看到存储在这个集合中的播放器时,您知道他们执行了命令。UUID是一个36个字符的字符串,对每个播放器都是唯一的,在每个服务器上都是相同的。你把Set做成这样:
final Set<UUID> players = new HashSet<>();接下来你需要下一个命令。我会这样做:
@Override
public boolean onCommand(CommandSender sender, Command cmd, String cl, String[] args) {
//Check if your command was executed
if(cmd.getName().equalsIgnorecase("yourCommand")){
//Check if the executor of the command is a player and not a commandblock or console
if(sender instanceof Player){
Player player = (Player) sender;
//Add the player's unique ID to the set
players.add(player.getUniqueId());
}
}
}现在,您接下来要做的是听一听PlayerInteractEvent,看看玩家何时点击这本书。如果您看到播放机在Set中,您就知道他们已经执行了命令。下面是我如何使EventHandler
@EventHandler
public void onInteract(PlayerInteractEvent event){
//Check if the player right clicked.
if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK){
//Check if the Set contains this player
if(players.contains(event.getPlayer().getUniqueId()){
//Check if the player had an item in their hand
if(event.getPlayer().getItemInHand().getType() == Material.BOOK){
//Remove player from the set so they have to execute the command again before right clicking the book again
players.remove(event.getPlayer().getUniqueId());
//Here you can do whatever you want to do when the player executed the command and right clicks a book.
}
}
}
}所以我所做的是,当播放器执行命令时,将它们存储在一个Set中。接下来请收听PlayerInteractEvent。这基本上是一种每次玩家交互时调用的回调方法。这可能是当一个玩家踩着一个压力板,当一个玩家左右点击一个街区或空中等等。
在该PlayerInteractEvent中,我检查播放机是否存储在该Set中,播放机是否在空中单击或右击某个块,并检查播放机手中是否有一本书。如果这一切都是正确的,我将从Set中移除播放机,因此他们必须再次执行命令才能执行相同的操作。
另外,不要忘记注册事件并实现Listener。
