# Mana

Use this variant to make the slot able to fill/drain mana from the machine internal buffer to/from an mana container item placed in that slot.

The fill/drain behavior is determined by the "mode" property of the item component : 

* "input" will transfer the mana from the item to the machine buffer.
* "output" will transfer the mana from the machine buffer to the item.

### ID

```json
"variant": "custommachinery:mana"
```

### Accepted items

Any mana container items (mana tablets, mana band,...) that match the filter defined in the item component ["filter"](https://frinn.gitbook.io/custom-machinery-1.19/creating-custom-machines/machine-components/item-component#name-filter) property.

### Example

A simple mana slot that transfer the mana  from the item to the machine internal buffer : 

```json
{
    "type": "custommachinery:item",
    "id": "manaInput",
    "mode": "input",
    "variant": "custommachinery:mana"
}
```
