CanMoveItem

OxideCarbonItem

Called to determine whether to move item.

Return true to allow the action and false to block it.

object CanMoveItem(Item local5, PlayerInventory playerInventory, ItemContainerId local1, int local2, int local3, ItemMoveModifier local4)

Method changed — check — the game method differs from the one the hook is recorded for in Oxide. The hook is still called, but its place may have shifted — worth checking after an update.

Parameters

local5: Item
playerInventory: PlayerInventory
local1: ItemContainerId
local2: int
local3: int
local4: ItemMoveModifier

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 CanMoveItem(Item local5, PlayerInventory playerInventory, ItemContainerId local1, int local2, int local3, ItemMoveModifier local4)
{
    Puts("CanMoveItem");

    // 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.
