Usage
Example
Here is a simple example to pick up the item from 3 items which are Coin, Mushroom and Star. Probability of each item is below.
- Coin: 60%
- Mushroom: 35%
- Star: 5%
<?php use LuckyBox\LuckyBox; use LuckyBox\Card\IdCard; // Items $items = array( 1 => array('name' => 'Coin', 'rate' => 60), // 60% 2 => array('name' => 'Mushroom', 'rate' => 35), // 35% 3 => array('name' => 'Star', 'rate' => 5), // 5% ); // Setup $luckyBox = new LuckyBox(); foreach ($items as $id => $item) { $card = new IdCard(); $card->setId($id) ->setRate($item['rate']); $luckyBox->add($card); } // Draw $card = $luckyBox->draw(); $item = $items[$card->getId()]; echo "You got {$item['name']}" . PHP_EOL;
Consume cards
Cards in LuckyBox are not consumable by default. This means that the cards can be drawn endlessly. If you want to consume the cards in LuckyBox, set consumable to true.
$luckyBox = new LuckyBox(); // Add some cards. $luckyBox->setConsumable(true); while (!$luckyBox->isEmpty()) { $card = $luckyBox->draw(); // Do something. }
Increase the accuracy
You may want to higher accuracy than percent (0 to 100). You can set the rate more than 100.
$card1 = new IdCard(); $card2 = new IdCard(); $card1->setRate(1023); // 10.23% $card2->setRate(8977); // 89.77%
Remove a card
- Remove one card
$luckyBox->remove($card);
- Remove all of the cards
$luckyBox->clear();
