FormAPI

First of all, I'm sorry that my English is not good. My problem is with the formapi. I'm adding a slider to my menu, I don't have any problems, but I want the slider option to be as much as the number of items in the inventory. I tried many ways but couldn't find a solution. Please help.

PHP:

public function Stone(Player $o){
            $f = $this->getServer()->getPluginManager()->getPlugin("FormAPI")->createCustomForm(function(Player $o, array $data){
                if($data[0] === null){
                if(!isset($data[1])){
                    return true;
                }
                }if(is_numeric($data[1])){
                    if($o->getInventory()->contains(Item::get(1, 0, $data[1]))){
                        $o->getInventory()->removeItem(Item::get(1, 0, $data[1]));
                        EconomyAPI::getInstance()->addMoney($o->getName(), 1 * $data[1]);
                        $o->sendPopup("§a" . $data[1] . " adet taş satıldı!");
                    }
                    }else{
                        $o->sendPopup("§cBir sayı gir!");}});
            $f->setTitle("Sat->Bloklar->Stone");
            $f->addLabel("\n§f» Adet Fiyatı: §a1TL\n");
            $f->addSlider("Değer Gir" , 1, 64, 1); // I want it to be as much as at max inventory.
            $f->addInput("", "Satılacak miktarı buraya giriniz.");
            $f->sendToPlayer($o);}

 

The inventory has 27 storage slots, and 9 hotbar slots. (excluding the Armor slots and off-hand slot)
Each slot can hold upto 64 or 16 items depending on the category. Therefore 27*64 = 1,728 and 9*64 = 576, simple addition. 1,728 + 576 = 2,304.
This is the total amount of items you can have in your inventory.

PHP:

 $f->addSlider("Slider" , 1, 2304, 1); // I want it to be as much as at max inventory.

Unless you want to calculate how many items does a player have this could work.

PHP:

$items_count = 0;
foreach($player->getInventory()->getContents() as $item){
    $items_count += $item->getCount(); // Add item count to variable
}
$f->addSlider("Slider" , 1, $items_count, 1);


 

This code working but its calculates all inventory. It can only calculate the amount of stone?

Edit: I solved it. Now just calculates stone.

 

@ErikX i got an error. If the amount is less than 1, it gives an internal error. I'm sending you my code. I couldn't find how to fix it.

PHP:

public function Stone(Player $o){
            $f = $this->getServer()->getPluginManager()->getPlugin("FormAPI")->createCustomForm(function(Player $o, array $data){
                if($data[0] === null){
                if(!isset($data[1])){
                    return true;
                }
                }
                if(is_numeric($data[1])){
                    if($o->getInventory()->contains(Item::get(1, 0, $data[1]))){
                        $o->getInventory()->removeItem(Item::get(1, 0, $data[1]));
                        EconomyAPI::getInstance()->addMoney($o->getName(), 1 * $data[1]);
                        $o->sendPopup("§a" . $data[1] . " adet taş satıldı!");
                    }
                    }else{
                    $o->sendPopup("§cBir sayı gir!");}
                
                    foreach($o->getInventory()->getContents() as $item){
                        if($item->getID() == "1"){
                        $miktar = $item->getCount();
                        }}
                    if($miktar < 1){
                        $o->sendPopup("you dont have stone");
                    }

                });

 

What’s the error?

 

$miktar is not defined. But its working if i have stone. If i didn't have stone server crashing with internal error. I want to make; if players dont have stone, stone ui dont open and sendPopup you dont have stone.

 

PHP:

foreach($o->getInventory()->getContents() as $item){
     if($item->getId() === "1"){ // How is this even working? I thought getId() returns int? and this is a string...
          $miktar = $item->getCount();
     }
}
$item = Item::get(Item::STONE);
if(!$player->getInventory()->contains($item)){
          $o->sendPopup("you dont have stone");
}


Use function Inventory->contains()!

 

So an example would be like this:

PHP:

// Code where it calls the form function
$item = Item::get(Item::STONE);
if(!$player->getInventory()->contains($item)){
          $player->sendPopup("You dont have stone in your inventory!");
          return false;
}
$this->openForm($player);
return true; 


 

Thanks, working.
