Disable plugin and command in config.yml

Is there any way that i can chose in the config.yml to enable or disable a command of the plugin or the entire plugin?

Yes. You can set the variable in config.yml. Example:

Code:

enabled: true 

Then in onEnable() function of your plugin put:

PHP:

$this->cfg = $this->getConfig()->getAll();
if($this->cfg["enabled"] != true){
    $this->getPluginLoader()->disablePlugin($this);
}

This doesn't work. You should suicide by $this->getPluginManager()->disablePlugin($this)

it crashed on me, i changed it to $this->getServer()->getPluginManager()->disablePlugin($this);

It works on me the @EvolSoft's method

Oops. You understand anyways

It won't. It won't deregister the handlers and blah. Also, return at the end of the if block.

In fact, doing $this->getConfig()->get("enabled") is as (or even more) efficient as (or than) storing the array to a field first.
