I'm creating a simple level-up system and I'm looking to base the stats gain on curves so I can tweak them easier, I know it's a math function, but I have no idea what to search for.
I need to create this curve and get the value every x increment.
the engine I'm using is Ren'py and the language python. if you can tell me the terms to search for, I might be able to find something on the topic.
