[HELP] Inventory - itemPlus

[India]

Hello, i have inventory system for DayZ Gamemode, if i delete the values there, it gives an error. Cause trying to attract a value that is not. If there is no value, i want it to be "1". so you can take 1 item when the value is empty.

function onPlayerMoveItemOutOfInventory ()
	hideRightClickInventoryMenu ()
	if playerMovedInInventory or getNetworkStats().packetlossLastSecond > 10 then return end

Replace itemPlus with (itemPlus or 0) if you want to ALWAYS be at least 1 replace the 0 with 1

 

That should do it

By setting items client-side you are inviting "hackers" to your server. Be aware that someday someone will exploit that you've doing it incorrectly, which will result in player copying items and so on.
