Scores

Implement leaderboards in your game to allow anyone to battle it out for the top spots. You create the leaderboards, you control the scoring. You can even allow guests to score without a Game Jolt account.

Functions

The following functions are provided for working with scores and leaderboards:

Structs

GameJolt_Scores_Add

This function adds a score representing the logged user. This is an asynchronous function that will trigger either the callback_success method (if task is successful) or the callback_failed method (if task fails).


Syntax:

GameJolt_Scores_Add(table_id, score, sort, extra_data, [callback_success], [callback_failed])
Argument Type Description
table_id real The ID of the score table to submit to.
score string This is a string value associated with the score.
sort real This is a numerical sorting value associated with the score. All sorting will be based on this number.
extra_data string If there's any extra data you would like to store as a string, you can use this variable.
callback_success method The callback function executed when the request succeeds ✴️ OPTIONAL
callback_failed method The callback function executed if the request fails (error message is passed as argument) ✴️ OPTIONAL

Returns:

N/A

Example:

GameJolt_Scores_Add(668889,"Points: " + string(points), points, "this is some metadata",
    function()
    {
        show_message_async("Score submitted successfully!")
    });

The code above will submit a score value for the current logged user to a given table_id, and print a success message if it succeeds.

GameJolt_Scores_Add_Guest

This function adds a score representing a guest user. This is an asynchronous function that will trigger either the callback_success method (if task is successful) or the callback_failed method (if task fails).


Syntax:

Argument Type Description
guest string The guest's name.
table_id real The ID of the score table to submit to.
score string This is a string value associated with the score.
sort real This is a numerical sorting value associated with the score. All sorting will be based on this number.
