Question

I want to be able to rank users based on how quick they have completed each level. I want this to be an overall leaderboard I.e. shortest overall time for all levels.

The problem here is that for each level completed the totally completion time goes up. But I want to ensure that the leaderboard takes that into account so that a user having completed 10 levels will rank more highly than someone with only 1 completed level.

How can I create some kind of score based on this?

Answer 1

Before submitting the time to leader board.

You could perform a modulation on the total time by the number of levels completed, then for each level completed reduce it by a set amount so people who complete all levels with the same average time will score better then people with the same average time but with fewer levels.

My Preferred Method:

Or you could express it with a score value.
level complete = 1,000.
Each level has a set time limit bonus, the longer you take the less bonus u get.
eg

I Complete the level in 102 secs Goal time is 120 secs

I get 1,000 points for completion and 1,500 points for each second
that i beat the Goal time for.

This way i will get 1,000 + (18* 1,500) = 28,000 points

Next guy completes in 100 secs

He Gets 1,000 + (20*1,500) = 31,000 points
