Hey, i have an issue trying to create the item after the =
waterIds = {[2712] = 8788, [2700] = 8785, [2701] = 6431, [2702] = 6432, [2708] = 8792, [2711] = 8786},
Trying something like:
doCreateItem(itemEx.uid,config.waterIds[itemEx.itemid])
But it wont work, how does doCreateItem work? Can someone explain?
