Check if Command exist

hello

My plugin uses a feature where server admins type a command without the / in the chat. What I try to make is that the plugin checks if this command exists then stores it for later use. I am trying to make it with a try/catch approach but I dont know how exactly check if this command exist. the commands that are used can vary from /pex user <player> group set <group> to /give <player> <random item> <random ammount>, this offcourse without the /. the admin will use it for example as pex user player group set Demote. when the plugin/server uses the command the "player" will automatticly replaced by the player who triggers the command.

does anyone have a idea what catch I need to use?

Try something like this:
Bukkit.getServer().getPluginCommand(Command).execute(Player, Lable, Args[]);

Edit:
For non plugin command i dont really know but you can maybe add / in the begin of the chat message

 

Seems legit.

 

Fozie Lol.

Admin: "Hey, how are you?"
Server: Hey isn't a command

guitargun For every command? While I could tell you how to check if a command exists, I'd be better off just telling not to do that. You'll run into conflicts sooner rather than later.

Admin [to a rule breaker]: "Stop breaking rules please"
*server closed*

See the problem? How was the server supposed to know that the stop was meant to be said rather than done? It is a command, after all.

Whoops did not think of that xD

You have to enter somekind of "command mode" then, but for my self i thinks its useless then and only take memory.

 

Fozie I remember the Factions plugin used to do this, but that was fine. It only attempted to do it for its own command, so there wasn't really any conflict. Sure you couldn't say a message like "f hello" but who the hell wanted to start a message with "f " anyway? Besides, iirc, there was a config option to disable the feature.

 

thats not what is happening. I am making a quest plugin. when the user is done with the quest a command triggers. this can vary from a /give to a pex command. the admin stores the command when create the quest. its not when he says stop breaking the rules that the server checks for a command. it only checks when storing the command

 

guitargun Oh, I think I know what you mean though. And you just want to check before storing that command that it is actually a command?

 

exactly

 

Code:java

  @EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerCommandPreprocess(PlayerCommandPreprocessEvent event) {
        if (!event.isCancelled()) {
            Player p = event.getPlayer();
            String command = event.getMessage().split(" ") [0];
            HelpTopic htopic = Bukkit.getServer().getHelpMap().getHelpTopic(command);
            if (htopic == null) {
                p.sendMessage(COMMAND DOES NOT EXIST);
                event.setCancelled(true);
            }
        }
    }

 

if I understand that correctly it checks always for the command to exists but not if there is a typo in the command for example you want to use /pex user guitargun group set User and you typ /pex user guitargun goup ste User. will that send the command does not exists also?

 

No it gets the command not args so /pex

 

is there an method to check if the args are correct as well?

 

Impossible, since args being correct is subjective based on plugin, EX: plugin returns 'player does not exist'.

Hence, making sure command is correct is the job of the admin.
