OnVendingShopOpen

OxideVending

object OnVendingShopOpen(VendingMachine vendingMachine, BasePlayer player)
object OnVendingShopOpen(InvisibleVendingMachine invisibleVendingMachine, BasePlayer player)
object OnVendingShopOpen(NPCVendingMachine vendingMachine, BasePlayer player)

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

Parameters

vendingMachine: VendingMachine
player: BasePlayer

Return value

objectReturn a value of the method's result type and the game returns it immediately; null continues as usual.

Example

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

private object OnVendingShopOpen(VendingMachine vendingMachine, BasePlayer player)
{
    Puts("OnVendingShopOpen");

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

    // to affect the game:
    // return null; // null — the game continues as usual
}

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