Ive seen alot of ways to save properties, most of them all fancy and confuzing (Yes, confuzing) But i have invented a simple and easy way of doing it. How? you ask.
Overlaying Scenes. I will give you a simple example.
There are 2 scenes in your game, one is called Scene 1, and the other is Scene 2. you have somthing like a health bar, or somthing that involves a property and you want to be able to have the same property value in scene 2 as in scene 1. All you need to do is add a simple overlay scene. Add another scene called “Property”, then put your health bar or property in there. then go to scene 1 and scene 2 and give them a logic set out like this:
always > and > scene > add overlay scene: Property
And there you have it.
