Im having trouble with a specific object Im making and REALLY need help. Basiclly its SCP-458 an infinite pizzabox, and with some research I found out about containerCallback() Called when the container contents have been changed or interacted with in a GUI Pane. To have the callback use a different name, add the parameter "containerCallback" : "[function name]" to your object's config file. But making it work in LUA(especially cause I have no experience) is really hard. "is what I want it to do is detect if the contents of it have been tampered with and if so refill it with pizza"
