# Drop

**Use one of these methods to add a** [**Drop Requirement**](https://github.com/Frinn38/Custom-Machinery/wiki/Drop-Requirement) **to the recipe.**

```javascript
//Check for a specific item.
.checkDrop(item, amount, radius)
//Check for any item.
.checkAnyDrop(amount, radius)
//Check for a list of items.
.checkDrops(filter, amount, radius)
.checkDrops(filter, amount, radius, whitelist)

.consumeDropOnStart(item, amount, radius)
.consumeAnyDropOnStart(amount, radius)
.consumeDropsOnStart(filter, amount, radius)
.consumeDropsOnStart(filter, amount, radius, whitelist)

.consumeDropOnEnd(item, amount, radius)
.consumeAnyDropOnEnd(amount, radius)
.consumeDropsOnEnd(filter, amount, radius)
.consumeDropsOnEnd(filter, amount, radius, whitelist)

.dropItemOnStart(item)
.dropItemOnEnd(item)
```

* The `item` param must be an item created using `Item.of()`. \
  Example : `Item.of("minecraft:dirt")`
* The `amount` param must be a positive integer, it represents the amount of items checked/consumed.
* The `radius` param must be a positive integer, it represents the maximum distance to the machine the items will be searched.
* The `filter` param must be an array of items. \
  Example : `[Item.of("minecraft:diamond"), Item.of("minecraft:cobblestone")]`. It represents a whitelist of items to search.
* The `whitelist` param must be a boolean, if set to `false` the filter will be a blacklist instead of a whitelist.

### Example

```javascript
ServerEvents.recipes(event => {

  event.recipes.custommachinery.custom_machine("custommachinery:power_crusher", 100)
  .checkDrop(Item.of("minecraft:diamond"), 1, 10)
  
})
```
