[SOLVED] onItemStoppedBeingHeld event with ItemStack parameter?

[hiotewdew]

I'm looking for a method I can override in the item class to detect when the item is moved, dropped, or not being held by the player anymore. I know onItemDropped exists, but I need one for when it is not being held anymore. Does such a method exist? It also needs itemstack as a parameter (or player and hand)

Not sure if it is the best way, but using onUpdate and checking the stack's slot index may work. May also cause way too much lag...

Please define moved. Do you mean changes slots? In the player's inventory only or in any container? If you want any container then the best you can do is subscribe to a tick event, iterate all players, look at their open containers(will be the inventory if the player isn't looking at the GUI at the moment), iterate the stacks in that container and check their slot index against the one on the previous tick. If it changed the item was moved.

Keep in mind that it is pretty much impossible to detect slot changes of the item if it happens without the player present, such as a hopper inserting/extracting an item.

Check the current slot of your item each tick, compare it to the slot on the previous tick. If the slot changed and was the held one then it's not being held anymore.

Is there a way that doesn't involve checking every tick?

No, not as far as I am aware. You could check every X ticks I suppose but you might then miss something. Do you have issues with checking every tick? Performance should not be a concern since you are not doing much, just comparing ints.
