Incremental Achievements question

Fabri Damazio

I have one doubt about incremental achievement.

I have one incremental achievement where the player need collect STARS. I use this formula:

(total_stars/100) *100

Every star collected is equal 1%

My question is: I need save the "total_stars" attribute or it need be zero every time i start the game?



Ex: if the player collect 5 stars. I need save 5 to "total_stars" to next time he play the counter start on 5 and increment? Or i don't need save it and when he start again it will start on zero?

I think you need to save the total stars.
In my game I have a atribute that is +1 every time the player does a certain thing. I update the game center achievement after each round with (total/goal)*100
What I also do is ad a maximum to it. It's probably not a big deal but I can imagine game center freaking out if you send over 100% to it.
So I do max(100,(total/goal)*100))
Hope that makes sense.

It seems like you're asking if you should save the total_stars or not, but you don't explain how you want it to work. Do you want it to keep track of the previous number of stars? If so, save it. If not, don't.

It's also a bit strange that you're converting the number of stars into a percent and then back to a whole number. The expression (total_stars/100)*100=total_stars... right? So no need for the formula. Just keep track of game.total_stars.

It was an exemple. (a bad exemple)

ok, lets suppose i use:

(total_stars/500) *100

Do i need save the total_stars or it needs to start always on zero to work with my achievements?

Do i need save my total star to 500 to unlock the achievement or the gamecenter do it for me?

Okay, so I haven't used gamecenter achievements... someone else will have to help you. But now I understand what you're asking!

Ow, that should be min where it says max.
