How do I delay an input in a script?

Question

I want to load an instance of my inventory scene with the press of "i" and then close it again with the press of "i". At the minute my inventory scene is loading and is visible but when I press i again i think it closes and then opens again instantly.

Here is the script:

Player script:

func unhandledkeyinput(event):
if Input.isactionjustpressed("openinventory"):
var inventory = load("res://Scenes//Inventory.tscn").instance()
addchild(inventory)
print("i")
get_tree().paused = true

Inventory script:

func unhandledkeyinput(event):
if Input.isactionjustpressed("openinventory"):
queuefree()
get_tree().paused = false

when I press "i" when the inventory is up it prints "i"

Cheers for the help.

Maybe you need a cool-down timer.

So when after open (or close) the inventory screen:

1) create a global flag, for example is_active = false which will cause your script(s) to ignore input, for example

if Input.isactionjustpressed("openinventory") && is_active:

2) start a short timer. On timer complete, set the flag is_active = true so input will be accepted again
