Husk at spilleren stadig skal have itemflip.use for at bruge menuen.
import:
dk.plexhost.itemflip.userinterface.UIOptions
dk.plexhost.itemflip.ItemFlipPlugin
rightclick on entity:
if citizen id of event-entity = id på din npc:
ItemFlipPlugin.getInstance().getUIManager().openGui(player, "start", new UIOptions())
