## Properties

### type :: `"item"`

### name :: ItemID

The name of an ItemPrototype.

### amount :: uint16 optional

### amount_min :: uint16 optional

Only loaded, and mandatory if `amount` is not defined.

### amount_max :: uint16 optional

Only loaded, and mandatory if `amount` is not defined.

If set to a number that is less than `amount_min`, the game will use `amount_min` instead.

### probability :: double optional

Default: `1`

Value between 0 and 1, `0` for 0% chance and `1` for 100% chance.

The effect of probability is no product, or a linear distribution on [min, max]. For a recipe with probability `p`, amount_min `min`, and amount_max `max`, the Expected Value of this product can be expressed as `p * (0.5 * (max + min))`. This is what will be shown in a recipe tooltip. The effect of `ignored_by_productivity` on the product is not shown.

When `amount_min` and `amount_max` are not provided, `amount` applies as min and max. The Expected Value simplifies to `p * amount`, providing `0` product, or `amount` product, on recipe completion.

### ignored_by_stats :: uint16 optional

Default: `0`

Amount that should not be included in the item production statistics, typically with a matching ingredient having the same amount set as ignored_by_stats.

If `ignored_by_stats` is larger than the amount crafted (for instance due to probability) it will instead show as consumed.

Products with `ignored_by_stats` defined will not be set as recipe through the circuit network when using the product's item-signal.

### ignored_by_productivity :: uint16 optional

Default: `0`

Amount that should be deducted from any productivity induced bonus crafts.

This value can safely be set larger than the maximum expected craft amount, any excess is ignored.

This value is ignored when allow_productivity is `false`.

### show_details_in_recipe_tooltip :: bool optional

Default: `true`

When hovering over a recipe in the crafting menu the recipe tooltip will be shown. An additional item tooltip will be shown for every product, as a separate tooltip, if the item tooltip has a description and/or properties to show and if `show_details_in_recipe_tooltip` is `true`.

### extra_count_fraction :: float optional

Default: `0`

### percent_spoiled :: float optional

Default: `0`

Must be >= `0` and < `1`.
