Solved Main class not found

Hello, I've been trying for an hour to get my plugin to work but it says that the main class can not be found. Hope you can help me.

 

code?

 

Plugin.yml

PHP:

name: UpCommand
main: SJames\UpCommand\Main
api:
- 3.7.3
version: 0.1.0
author: SJames

permissions:
  up:
    usage: "/up"
    default: op
    description: "Go up and put glass under your feet


Main.yml

PHP:

<php
namespace SJames\UpCommand;
use pocketmine\Blocks;
use pocketmine\Player;
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\utils\TextFormat as c;
use pocketmine\Vector3

class Main extends PluginBase {
  public function onEnable(){
  }
  public function onCommand(CommandSender $player, Command $cmd String $label, array $args) :bool {
    switch($cmd->getName()){
      case "up"
        if(!($player instanceof Player)){
          $sender->sendMessage(c: :BOLD.c: :DARK_RED."Please run this command in-game.");
        }else{
          $x = $player->getX();
          $z = $player->getZ();
          $level = $player->getLevel();
          $y = $args[0]
          $coords = [$x, $y, $z];
          $player->teleport(new Vector3(...$coords));
        }      
      }
    }
  }
}


 

are they php files or .txt files

 

Plugin.yml
And
Main.php

 

Your php tag is missing a question mark - the code in Main.php starts with <php instead of <?php .

 

Oh my God..finally.. Thank you so muuch!
