How to make tool undropabble so player cant drop it to other player when player press backspace tool will drop srry for my english
You don't need a script for this, well it is optional, but I'd recommend you this better way:
Go to the tool, on the properties, you will find something called "CanBeDropped". Turn the checkmark to false by clicking it.
Also you can also use @Shounak123 answer, it also works, but it's more complicated and I'd suggest you the easier way.
Put a script in the tool and paste: script.Parent.CanBeDropped = false
