Hello, im really interested in creating a game similar to Papa’s Burgeria in GDevelop but i don’t know how, i searched all the internet but couldn’t find anything. If someone gives me a idea it would be nice.
I guess you can use timers to increase a variable and that variable determines how good the food is cooked or if it is overcooked. You can use the draggable behaviour and maybe the tween behaviour for moving those foods around. We can’t tell you how to make a game but we will assist you when you need help.
If you are a beginner, you should at first learn the basics and other stuff first
