Experience Bar Question

EricTippett

Hey Everyone,
I am currently trying to create an experience bar. I looked at the health bar tutorial, but the experience isnt a set number every level.
They way I have experience set up right now is in an attribute called Player1Experience. Then I made an rule on the Player1Actor that as an Attribute game.Player1Experience is greater/equal to 100 * game.Player1Level^3
So the experience is saved after each level towards the next requirement.

I was trying to think of some way to have the old experience goal = 0 width and then have the new experience goal = the full width of the exp bar (currently 600)

So how would I make an experience bar for this, since both the starting number and level up number change every level?

I have made an example-file on how I would do it. Take a look at it and hopefully you will be able to make your own code work.

This is made as an iPhone project, therefore the "Full Exp Bar"-attribute is set to 400. You can change it to whatever you like and the "Player Level" and "Exp Bar" is calculated automatic.

Great :-)

Do you want another BAR or combine HP and XP into one BAR?

HC_DK

First, I would NOT combine those two :-) But that is your call....

Try to solve the HP bar yourselves and if you run into trouble, let me know. I wanna help BUT helping is not the same as making the code :-) And you will learn a lot more by doing it yourselves.

You can use a lot of the "code" in the Exp Bar-example or else have a look at:

Oh and I got it to restart every level with this
Constrain Attribute: self.size.Width = game.Player1Experience - (100*(game.Player1Level-1)^3)

However, I need it to fill up to 600 pixels wide and 600 would be the bar at 100% experience. So how could I tell it to fill up according to that?

EricTippett

Thanks, I downloaded it and saw how you created it. I noticed it is always 400 exp needed, but in mined the needed exp changes every level.

So for mine the width of the bar is 0 - 600 pixels.
The start point of the bar at 0 px would be the last levels exp goal so 100 * (game.Player1Level - 1) ^3.
The end point of the bar at 600 pixels would be 100 * (game.Player1Level)^3.

Do you know how I would create that since the start and end is always changing and isnt a set number?

EricTippett

Hey Thanks! Yeah its working perfect now!
Do you think this would work for when I get to HP bars that will also have a max value that will change every level gained?

EricTippett

I was going to have another bar as an HP bar. But every time the player upgrades the HP (using currency found in the game), the HP would have a new max HP and the bar would have to notice that.

But just wondering since you mentioned it.. how would you combine a HP bar into a XP bar lol? Wouldnt that be a weird mechanic, so instead of losing life when hit you lose XP?

Thanks for helping me out by the way!

EricTippett

Oh lol yeah I watched those a couple days ago. I made a basic health bar but I was just trying to apply this upgradable hp aspect to it.
But yeah I was able to create a HP and Energy bar with your method, so thanks!

@EricTippett: Great you got it working :-)

Im curious, could you be more specific regarding the attributes you're using in your game, I wanted to implement the same method, I'm not looking for an experience bar at the moment, just the logic behind tracking experience and leveling up.
