Code Error

I keep getting this crash dump when I load this plugin. What did I do wrong here?

PocketMine-MP Crash Dump Fri Oct 6 21:18:49 EDT 2017

Error: Declaration of MenuSystem\Commands\BaseCommand::getPlugin() must be compatible with pocketmine\command\PluginIdentifiableCommand::getPlugin(): pocketmine\plugin\Plugin
File: MenuSystem-master/src/MenuSystem/Commands/BaseCommand
Line: 11
Type: E_COMPILE_ERROR

THIS CRASH WAS CAUSED BY A PLUGIN
BAD PLUGIN: MenuSystem v3.0.0

Code:
[2]
[3] namespace MenuSystem\Commands;
[4]
[5] use MenuSystem\Main;
[6]
[7] use pocketmine\command\Command;
[8] use pocketmine\command\CommandSender;
[9] use pocketmine\command\PluginIdentifiableCommand;
[10]
[11] class BaseCommand extends Command implements PluginIdentifiableCommand
[12] {
[13] private $plugin;
[14] public function __construct(Main $plugin, $name, $description, $usageMessage, $aliases)
[15] {
[16] parent::__construct($name, $description, $usageMessage, $aliases);
[17] $this->plugin = $plugin;
[18] }
[19] public function execute(CommandSender $sender, $commandLabel, array $args)
[20] {
[21] if ($this->testPermission($sender)) {

 

Wait, what line should I replace that with? And no.

 

<?php

namespace LobbySystem\Commands;

use LobbySystem\Main;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\PluginIdentifiableCommand;

class BaseCommand extends Command implements PluginIdentifiableCommand
{
private $plugin;
public function __construct(Main $plugin, $name, $description, $usageMessage, $aliases)
{
parent::__construct($name, $description, $usageMessage, $aliases);
$this->plugin = $plugin;
}
ppublic function execute(CommandSender $sender, $commandLabel, array $args)
{
if ($this->testPermission($sender)) {
$result = $this->onExecute($sender, $args);
if (is_string($result)) {
$sender->sendMessage($result);
}
return true;
}
return false;
}
public function onExecute(CommandSender $sender, array $args)
{
}
public function getPlugin()
{
return $this->plugin;
}
}

Current Code

 

The bolded things in the code should fix the errors (try it and see if it is fixed)

 

public function getPlugin(): Plugin{
return $this->plugin;
}

 

Use CODE tags!

 

That's COMPLETELY incorrect

 

I changed it in the 2nd post read before you speak lol

 

it would be

public function getPlugin(): BaseCommand{
return $this->plugin;
}

not just Plugin

 

Are you sure?

 

Read the error:

Code:

Declaration of MenuSystem\Commands\BaseCommand::getPlugin() must be compatible with pocketmine\command\PluginIdentifiableCommand::getPlugin(): pocketmine\plugin\Plugin

It says that there is something wrong with the getPlugin() function in your BaseCommand.php file. It must be compatible with:
pocketmine\command\PluginIdentifiableCommand::getPlugin(): pocketmine\plugin\Plugin

The getPlugin() functions needs to return a Plugin object, that means you need to change public function getPlugin() to public function getPlugin(): Plugin. Don't forget to add the Plugin class with the use keyword.

 

Yes I’m sure, I have had to fix the error many times

 

So what's the right code?

 

public function getPlugin(): BaseCommand{
return $this->plugin;
}

 

Like where do I put it?

 

Where does the error say that getPlugin() should return a BaseCommand?

@WinterBuild7074 and @themestl already answered this correctly above so please don't add wrong information. When overriding a core class you must respect the types for both the arguments passed, and the return type (here the function getPlugin() must return... a Plugin object) as specified after a colon : and just before the opening curly brace { of your function.

That said, it looks like there's a whole load of other problems with this code (ppublic function??), although without using code blocks it's impossible to read :-/ Why not contact the developer instead of asking people here to fix it for you? It's fine asking for help, but if you don't understand what a 'return type' is then you'll be unable to fix it yourself even if we tell you how.
