How Can I place a chest and open it via command?

I would like to know if any of you know how You can place a chest with custom name and open it via command.


here is an example:

PHP:

switch($command->getName()) {
            case "shop":
                   Open Chest
}

 

look here https://github.com/Muqsit/ChestShop/blob/master/src/ChestShop/Main.php

 

I have looked at other plugins including that one... here is my code so far:

PHP:

public function onCommand(CommandSender $sender, Command $command, string $label, array $args) : bool{
        if(strtolower($command->getName()) == "shop"){
            if($sender->hasPermission("shop.cmd")){
                $sender->sendMessage(c::GOLD. "Opening Shop!");
                $this->sendInventory($sender);
            }
        }
    }

and the error message when i type the command into chat:

Code:

[Server thread/CRITICAL]: Unhandled exception executing command 'shop' in shop: Call to undefined method Atomization\shop\main::sendInventory()
[11:17:22] [Server thread/CRITICAL]: Error: "Call to undefined method Atomization\shop\main::sendInventory()" (EXCEPTION) in "shop/src/Atomization/shop/Main" at line 50

So i have asked already, how can i open a chest via command?

 

function sendInventory is not defined

 

That doesn't help much... can any of you help me fix it? how can i get "function sendInventory" defined?

 

Okay lmao I'm a nooby code I can't even get my plugin to work but would it be like
$sender = $player? Or something saying sender is player?

 

Debugging 101
Step 1: Look at your code and find what line the error occurs according to the error given.
Step 2: Pay attention to the type of error you are given (in your case it is a missing function).
Step 3: If you have not created the function within the called class, create the function.
Step 5: Profit!

Spoiler: Hints

Spoiler: Hint 1

The error is where it says

PHP:

$this->sendInventory();

Spoiler: Hint 2

Your error is

Code:

"Call to undefined method Atomization\shop\main::sendInventory()"

Spoiler: Hint 3

Create the following function and implement it to do what you need it to in your main class

PHP:

public function sendInventory(Player $player) {
    //TODO
}

Spoiler: Hint 4

Notice there is no step 4...

 

Wtf this if not php learn forum :v Go to stackoverflow If you don't know how to define function

 

That helped somewhat, I looked back and saw that it was defined, it was just misspelled, however, I have an other error which i don't understand.

Code:

[10:48:47] [Server thread/CRITICAL]: Unhandled exception executing command 'addshop' in addshop: Return value of Atomization\shop\main::onCommand() must be of the type boolean, none returned
[10:48:47] [Server thread/CRITICAL]: TypeError: "Return value of Atomization\shop\main::onCommand() must be of the type boolean, none returned" (EXCEPTION) in "shop/src/Atomization/shop/Main" at line 75

And here is what it says in the function onCommand... begins on line 57

PHP:

public function onCommand(CommandSender $sender, Command $command, string $label, array $args) : bool{
        if(strtolower($command->getName()) == "addshop"){
            if($sender->hasPermission("addshop.cmd")){
             
             
                for($this->time = 3; $this->time >= 1; $this->time--){
                    $sender->sendMessage("§2Loading..§c $this->time");
                    if($this->time==1){
                        $this->sendInventory($sender);

                    }
                }
             
             
            }else{
                $sender->sendMessage(c::RED. "You cannot perform this action, for staff only");
            }
        }
    }

Any help is appreciated, I know that I may seem like a person that doesn't know anything, however, this is how I learn, from people who know how better than I do

 

return value

PHP:

return "value";

must be the type of boolean
boolean = true/false

http://php.net/manual/en/function.return.php

Spoiler: READ return MANUAL FIRST

Just type 'return true;' at the end of the onCommand function if you are lazy

 

What about if I told you that you have to create a tile.

 

Thank you for helping me understand what boolean values are, But I have one more question to ask before I mark this thread as Solved...

This is not an error question but rather seeking some assistance on how to achieve a task.
I was trying to make a countdown of 3 sec. before opening the shop, it will send a title saying, "Loding... 3, 2, 1" and then open the shop, I have made a for loop looping the loading title, but how do I make it last for 3 or more sec.?

PHP:

for($this->time = 3; $this->time >= 1; $this->time--){
                    $sender->sendMessage("§2Loading..§c $this->time");
                    if($this->time==1){
                        $this->sendInventory($sender);

                    }
                }    

"Anyone who helped me fixed any errors or help me add features to my plugin will be given credit
