How do I create an EXP Bar

Hi!

I have created an Level System, which menas with 3 Variables: Level,EXP,EXP To Next Level!

This works great! But now I have bought a EXP Bar from the scirra Shop.. How do I make it now that the EXP Bar is Filling, For Example, when you need 80 % EXP for level up, that the EXP Bar is 20% filled...

I followed this tutorial to do an EXP bar in my own game, it might help you : https://www.scirra.com/tutorials/182/ma ... cy-lifebar

it's the same principle, you only use different variables.
