OnItemCraft

OxideCarbonItem

Called when an item is crafted.

object OnItemCraft(ItemCraftTask local0, BasePlayer owner, Item fromTempBlueprint)
object OnItemCraft(IndustrialCrafter industrialCrafter, ItemBlueprint itemBlueprint)

Works — the game method in this build is the one the hook was written for.

Parameters

local0: ItemCraftTask
owner: BasePlayer
fromTempBlueprint: Item

Return value

objectThe returned value replaces the game result; null lets the game decide.

Example

object — you can affect the game: return a value to change or cancel the action.

private object OnItemCraft(ItemCraftTask local0, BasePlayer owner, Item fromTempBlueprint)
{
    Puts("OnItemCraft");

    // change nothing — the game continues as usual
    return null;

    // to affect the game:
    // return false; // your value instead of the game result
}

Works in both Oxide and Carbon: Carbon loads Oxide plugins as is.
