SetQuantity()

override bool InventoryItem::SetQuantity ( float value, bool destroy_config = true, bool destroy_forced = false, bool allow_client = false, bool clamp_to_stack_max = true )

inlineprotected

Set item quantity[related to varQuantity... config entry], destroy_config = true > if the quantity reaches varQuantityMin or lower and the item config contains the varQuantityDestroyOnMin = true entry, the item gets destroyed. destroy_forced = true means item gets destroyed when quantity reaches varQuantityMin or lower regardless of config setting, returns true if the item gets deleted.
