Correct implementation of levels?

Question

Mathematics

Hello! Help me please!

A new player enters,
exp = 0 is put into his base;
stepexp = 20;

PS exp - how much experience he gained, step_exp - how much it takes to go to the next level.

That is, we get at the moment that the player has level 0 (exp / step_exp = 0)

So that's my question. How to make the implementation of the issuance of experience, such as how much he needs to go to the next level.

I came across one video, it was just a review. There, the new player is like this
level 1 (0/20)
When a player is level 5, somehow, the player must collect 320 experience to move on to the next one.

5*20=100
how?

How do I correctly issue step_exp?

Thank you!

Answer 1

Usually experience is given by some exponential or quadratic function. The specific formula can be understood by looking at the numbers for all levels.
I can assume that in the case you describe, you need 2^level * 10 experience to the next level.

Answer 2

It's all relative and depends on your desired player growth rate. Right there it is necessary to balance everything - both the rate of issuing the exp, and the influence of the level on the complexity - and, as a result, the pace.
The simplest thing is to take something from ready-made systems - pathfinder, special, dnd and so on.
