# Position

Position requirement is used to make the custom machine recipe work only in some positions of the world.

The position requirement is an **input only** requirement, meaning that you don't have to define the `mode` property. 

It is used only to restrict or allow the usage of a recipe at certain positions of the world.

The requirement type of position requirement is : "`custommachinery:position"`.

### Properties

The position requirement has 1 mandatory property and 1 optional property.

#### Mandatory property

```json
"type": "custommachinery:position" //Mandatory to define a position requirement.
```

#### Optional property

#### Name : `positions`

#### Description :&#x20;

An array of position comparators used to check if the machine is in certain positions of the world.

A position comparator is defined by the axis you want to check (x/y/z), the mode of the comparator and the actual position you want to compare.

See all available [comparators](https://frinn.gitbook.io/custom-machinery-1.16/misc/comparator) here.

All the positions comparators must be match for the position to be validated.

#### Default : `empty`

Any positions are allowed.

#### Example :&#x20;

```json
"positions": ["x<<0", "z<<0"]
```

The recipe will run only if the machine is in negative coordinates in both X and Z axis.

### Example

A position requirement that will allow the recipe to run only if the machine is higher than the 128 y layer :

```json
{
    "type": "custommachinery:position",
    "positions": ["y>>128"]
}
```
