OxideCarbonVending

Called when buy vending item occurs.

object OnBuyVendingItem(VendingMachine vendingMachine, BasePlayer player, int local0, int local1)

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

Parameters

vendingMachine: VendingMachine
player: BasePlayer
local0: int
local1: int

Return value

objectReturn non-null to cancel the game action.

Example

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

private object OnBuyVendingItem(VendingMachine vendingMachine, BasePlayer player, int local0, int local1)
{
    Puts("OnBuyVendingItem");

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

    // to affect the game:
    // return false; // non-null cancels the game action
}

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