Hold down the mouse to shoot a clone. Read the Notes and Credits I've explain some scripts on what it does so you can understand better.
-Shake Effect by FUNUT. He deleted the tutorial video and there's also no one sharing the script.. So I found my way to get the script by searching the script on people's project (who credits FUNUT lol...). Notes: The one you see on the screen is my version/changed version of the original script. The script you must copy is in the sprite and the background. The sprite name you should copy is "Copy/Backpack it here".
