[Tutorial/Recourse] onCommand efficentcy

PRE-NOTE: This is basically all for saving time. You could figure this out on your own, but this is a good example of a nice way to do this.

Basically, in plugins that are using alot of onCommands (or commands in general), its usually nice to shorten down what the code does with methods. For most people (including me) every command I made, I did the usual:

Code:java

if (sender instanceof Player) {
if (sender.hasPermission("perm")) {
//code
} else {
sender.sendMessage("You dont have permission!");
}
 
} else {
sender.sendMessage("You can't be a player");
}

Well, it honestly got really old. So, I created some very simple methods to shorten things down.
Please note, you have to edit this a little your self. I'll tell you when in bold comments.

In the end:

Code:java

if (Helper.isPlayer(sender)) {
if (Helper.isAuthorized("plugin.permission") {
//Code
}
}

It shortens down the code, and still sends messages etc.

It also has a help message system, very nice.

HelpMessage exampel:

Code:java

player.sendMessage(Helper.getHelpMessage("heal");
//It would return the help message of heal

NOTE: Add this class and then rename the package to your liking. Then edit the class - comment if you have any questions.
Helper class:

Shouldn't the help message example have 2 closing brackets at the end like this

Code:java

player.sendMessage(Helper.getHelpMessage("heal"));

not like

Code:java

player.sendMessage(Helper.getHelpMessage("heal");

 

Th3Gam3rz Yeah, your correct.

 

You can just define the permission and no permission message in the plugin.yml and you don't need to handle permissions in your commands at all

 

drtshock Yes but color isnt/can't included.

 

Did you try putting a §(code) in it?

 

Just here to correct a typo in your title; it's "efficiency".
