[General] how to easy calculate the position of damage done in chart?

[stan0033]

so there are 6 playes and damage detection system. each time a hero deals damage it is added as + to his variable. How to calculate what is his position in the chart so the message at the end of the game to says: "You did X damage. you place 1st,2nd,3rd,4th,5th,6th."

Store the damage done in a variable for each unit.
Then when you need to calculate the leaderboard you sort the list(don't ask me how to do it best) and display it.

The whole thing could be a lot simpler if you saved damage done into array, thus making it MPI.

 

[stan0033]

what difference does it make if it's in array or not?

 

[Vinz]

You can loop through things, instead of doing them manually 6 times (or number of players). For example, if you do mass changing, you can just loop and check for a condition. And when you add damage dealt, you don't have to have a separate trigger for each player.

 

[Nichilus]

The difference is that everything related to the damage saving will require only 1 trigger.
I imagine you have either 1 trigger with multiple ITEs to check the player, or multiple trigger where each fires for 1 players only.

MPI type of systems are best when your system needs to differentiate only players (not units), which is the case here.

Also, the trigger for sorting damage will require many many ITEs if you use unique variable for each player, on the other hand if you use array, it will require 1 or 2 loops. The complexity and inefficiency decreases dramatically when using array for this.

Arrays are more scalable. If the number of players changes all that might be required to support it is a single integer variable change, the number of players.

The simplest approach is to store the damage in an array at the index representing the player slot number who dealt the damage. Then when the game ends you order it simply by a list of active players that you use an ordering algorithm on by comparing the damages dealt for that player.

Since ordering an unordered collection is inefficient, you would not want to do it continuously (multiple times a second). The best approach for a running ordering is to keep a persistent ordered list (ordered list of players) and update it each time a player deals damage. Each update will be performed very fast as mostly only 1 element will need to be checked (the player above him in damage ranking) and that will mostly fail (chances of players changing rank is very low compared with the number of times damage is dealt). You can also use this to order change to update UI and things efficiently in the case of a multiboard or leaderboard.

OK, I tried with the leaderboard. I made leaderboard and this message:

• Game - Display to (Player group(Players[(Integer A)])) the text: (You did + ((String(DAMAGE_DONE[(Player number of Players[(Integer A)])])) + ( damage. + (You place + (Position[(Position of Players[(Integer A)] in Leaderboard)] + (. You earned + ((String(HONOR[(Player number of Players[(Integer A)])])) + honor points.

one question : in order to sort the position of the player should I loop refresh every 0.10 seconds or it will sort automatically? And if I want the 1st player to be on top should I use descending of ascending order?

 

[Dr Super Good]

Leaderboards should sort automatically as you update them. As I already stated, there exists a lot of standard sorting algorithms in computer science so you do not have to use a leaderboard.

 

[Nichilus]

imo I don't think it is important to sort it all the time whenever damage is dealt, because he wants to show it only at the end.
You may sort the list too many times for no reason, which is why I think sorting it via two loops at the end will be best.
