Solved How to stop people from putting specific items in GUI?

At the moment I listen for InventoryClickEvent and check if the event.getCurrentItem has a specific name (like an item that opens options) we cancel the event. There are still ways to get the item in. For example: if you put your cursor over any empty slot in the GUI and press the number (on your keyboard) that corresponds with the slot the item is, the item will go into the GUI, and then it will become impossible to get it out. Any ideas?

 

umm,.. idk if there is any other way than just checking if the click was keyboard click and cancelling it right away coz i don't think it is possible to get the key that player pressed, but one other thing u can do is check if the player's inventory contains the item that u want not to be placed then only cancel the event
If i m wrong, don't judge... i m not a pro developer

 

Seems like a good idea. I'll try it right away.
Edit:
@rudraksha007 thank you for your response, however it wouldn't work, since I still want other items to be put in the GUI, just not the options one.

 

hold on!!! i said this:
if(event.getClick().isKeyboardClick()){
event.setCancelled(true);
}
now got it? they can't put by number keys but can by clicking or shift clicking

 

Hmmmm. This would work, but for tryhards this might a bit inconvinient. If there's no other way then sure, I'll do it.
Strange that keyboard clicks don't set the currentItem of the event

EDIT:
I just came up with a solution. I'll listen for InventoryCloseEvent, and if the item is in there it will be removed and given to the player. Marking Solved.

 

That is just a hotbar swap; it is pretty easy to fix.
You can get the button pressed using #getHotbarButton(). It will return -1 if it is a normal click.
