Achievements

Note: You are viewing the Unity version of this topic. To view this topic for native development, see Achievements (Native). To view this topic for Unreal development, see Achievements (Unreal).

Create trophies, badges, awards, and more to challenge your users to reach a goal or objective. Users can see the achievements their friends have earned creating a competition among friends. Achievements earned in your app can also be displayed in Oculus Home to show a user’s progress in and progression through a game. This guide shows you how to define global achievements, the SDK methods and Server-to-Server calls you can make to interact with the achievements service, and an example Unity implementation you can review. The Oculus Platform supports three types of achievements: simple, count and bitfield. Each achievement type has a different unlock mechanism.

• Simple achievements are all-or-nothing. They are unlocked by a single event or objective completion. For example, a simple achievement is unlocked when Frodo reaches Mount Doom.
• Count achievements are unlocked when a counter reaches a defined target. Define the Target to reach that triggers the achievement. For example, a target achievement is unlocked when Darth Vader chokes 3 disappointing Imperial officers.
• Bitfield achievements are unlocked when a target number of bits in a bitfield are set. Define the Target and Bitfield Length that triggers the achievement. For example, a bitfield achievement is unlocked when Harry destroys 5 of the 7 Horcruxes.

The Oculus Platform tracks and manages achievements. The platform displays a toast notification and plays a sound when an achievement is unlocked. Your app manages the triggers and updates for achievements and displays achievements to the user.

Create Achievements

The first step in adding achievements to your game is to define the achievements and how they are unlocked. To create an achievement, go to the Achievements tab on the Developer Dashboard. When you create achievements, you can choose to localize the achievement into multiple languages. When entering the achievement information, select Choose Languages, check the boxes of the languages you would like to localize into, and enter the information for the languages selected. The language displayed to the user is based on the locale set for the user’s device OS.

Select Create Achievement and enter the following information:

• API Name - The unique string that you use to reference the achievement in your app. The API Name is case-sensitive, the name you define in the Dashboard must exactly match the name you reference in your code.
• Title - The short descriptive name that the user will see.
• Description - The full description of the achievement. You may wish to describe how a user can unlock or earn this achievement.
• Unlocked Description - (Optional) This is a description that will replace the Description after the user has unlocked the achievement.
• Locked and Unlocked Icons - (Optional) The icons associated with the achievement. The Locked Icon will be displayed to users who have not earned the achievement, while the Unlocked Icon will be displayed to the users who have. If only an Unlocked Icon is provided, the Locked Icon will be a grayscale version of the Unlocked Icon. If neither is provided, a default icon will be used.
• Write Policy - Choose one of the two Write Policy options:
  • Client Authoritative is the default setting and means that achievement progress may be written or unlocked from the client app.
  • Server Authoritative means that the achievement can only be written or updated using S2S APIs listed below. This is typically used to reduce cheating when trusted servers are running the game sessions. Achievement information and progress may still be queried from the client app.
• Is Achievement Secret - Yes/No toggle that chooses whether the achievement title, description, icon, and progress will be hidden until the achievement is completely earned or unlocked. Default selection is No.
• Type - This is the type of achievement. The values are simple, count, and bitfield. See the description above for information about these achievement types.

Select Submit when you’re finished to save the achievement. You can update your achievements in the Developer Center at any time. Archiving Achievements You can archive achievements at any time. Archiving does not delete the achievement or a user’s progress, it hides the achievement and any progress the user. You can unarchive an achievement to restore visibility to users.

Integrating Achievements

Once you’re finished creating the achievements, you can integrate them in your game. When you call the functions in this section, make sure to use the achievement name you specified on the developer dashboard.

The following SDK methods can be called from your client app. Detail about each function can be found in the OVR_Requests_Achievements.h documentation in the Platform SDK Reference Content.

The following SDK methods can be called for any achievement that has a Client Authoritative write policy. If the achievement is Server Authoritative you’ll need to use the S2S REST calls in the section below to make updates from your trusted server.

Example Implementation

The following Unity example demonstrates setting an achievement to unlock on an event that you define. The following example is taken from the VRHoops sample app. Find the sample in the Oculus Integration Package for Unity. For more information, see Sample Apps.

The example first defines an achievement that was configured on the Developer Center called LIKES_TO_WIN. The example then checks for an update message to see if the achievement has been unlocked and, if true, sets the achievement as unlocked in the app. Otherwise, the game moves on and increments the count on the achievement if a game condition is met, in this example if a win is recorded.

using UnityEngine;
using System.Collections;
using Oculus.Platform;
using Oculus.Platform.Models;

public class AchievementsManager : MonoBehaviour
  {
    // API NAME defined on the dashboard for the achievement
    private const string LIKES_TO_WIOptional= "LIKES_TO_WIN";
    // true if the local user hit the achievement Count setup on the dashboard
    private bool m_likesToWinUnlocked;

    public bool LikesToWin
    {
        get { return m_likesToWinUnlocked; }
    }
    public void CheckForAchievmentUpdates()
    {
        Achievements.GetProgressByName(new string[]{ LIKES_TO_WIOptional}).OnComplete(
            (Message<AchievementProgressList> msg) =>
            {
                foreach (var achievement in msg.Data)
                {
                    if (achievement.Name == LIKES_TO_WIN)
                    {
                        m_likesToWinUnlocked = achievement.IsUnlocked;
                    }
                }
            }
        );
    }
    public void RecordWinForLocalUser()
    {
        Achievements.AddCount(LIKES_TO_WIN, 1);
        CheckForAchievmentUpdates();
    }
}

Making REST Requests for Server Achievements

If you set an achievement to Server Authoritative, you’ll need to make API calls from your trusted server to the Oculus service to increment and unlock achievements. See the Server-to-Server Basics page for information about interacting with the Oculus REST APIs.

Create or Update an Achievement (POST)

https://graph.oculus.com/$APPID/achievement_definitions

Example Response

{"id":"1074233745960170"}

Retrieve Achievement Definitions (GET)

Query achievement definitions allows you to get information about achievements to display to your users.

Request method/URL:

GET https://graph.oculus.com/$APPID/achievement_definitions

Parameters:

The field definitions are the same as in the create or update API call above. Server image URIs are provided instead of local file locations.

Example Request

$ curl -G -d "access_token=OC$APP_ACCESSTOKEN|$USER_ACCESSTOKEN"
-d 'api_names=["VISIT_3_CONTINENTS", "WALK_500_MILES"]'
-d "include_archived=true"
-d 'fields=api_name,achievement_type,achievement_write_policy,target,bitfield_length,is_archived,title, description,unlocked_description_override,is_secret,locked_image_uri,unlocked_image_uri'
https://graph.oculus.com/$APPID/achievement_definitions

Example Response

{
    "data": [{
        "id": "1074233745960170",
        "api_name": "VISIT_3_CONTINENTS",
        "achievement_type": "BITFIELD",
        "achievement_write_policy": "CLIENT_AUTHORITATIVE",
        "target": 3,
        "bitfield_length": 7,
        "is_archived": false,
        "title": "Achievement Title",
        "description": "How to earn me",
        "unlocked_description_override": "You did it",
        "is_secret": false,
        "locked_image_uri": "https://scontent.oculuscdn.com/...",
        "unlocked_image_uri": "https://scontent.oculuscdn.com/..."
    }, {...}]
}

Write (and Unlock) Achievement Progress (POST)

Write achievement progress updates a user’s progress on an achievement. This method accumulates progress, for count type achievements, instead of overwriting values. For example, add_count=25 will increment the count by 25, not set the current count to 25. This is so that conflicts that arise from updating achievements from multiple sources simultaneously or making progress from multiple devices in offline mode can be handled gracefully.

Request Method/URL:

POST https://graph.oculus.com/$USERID/achievements

Parameters:

Example Request

$ curl -d "access_token=$APP_ACCESSTOKEN|$USER_ACCESSTOKEN" -d "api_name=MY_ACHIEVEMENT"-d "add_bits=0011001" -d "add_count=25" -d "force_unlock=true"
https://graph.oculus.com/$USERID/achievements

Example Response

{"id":"1074233745960170","api_name":"MY_ACHIEVEMENT","just_unlocked":true}

The response will contain the parameter just_unlocked that indicates if this operation caused the achievement to unlock.

Query Achievement Progress (GET)

Retrieve a user’s progress for an achievement.

Request method/URI:

GET https://graph.oculus.com/$USERID/achievements

Parameters:

Example Request
