I am trying to add a cooldown for when you attack (press z and press x) so you cant just spam attacks, I know you can use the time.sleep function to break up actions but because its animated, whenever I try to break up the actions, it has a 1 second delay between each image, how do I fix this? (when answering could you please explain what you did as I am new to coding and want to learn)
