how do you make a tool able to use once? throwing wise?

how do you make it where once you throw the tool you cant pick it up again or it cant be use if you throw at another player they cant pick it up?

maybe try using debounce

local db = true

and after function

if db then -- if db is true then script can go on (if statement is checking if value between if .. then is true)

	db = false -- here we set db to false so now if statement will stop because db isnt true
