# Achievements

# Overview

AccelByte Cloud’s Achievement service is a tool developers can use to increase player engagement with their game. Recognizing players’ progress in your game and rewarding them with items or new characters not only fosters deeper enjoyment of your game but brand loyalty as well. There are two main types of achievements: incremental and non-incremental. Both of these types are explained below.

# Incremental Achievements

Incremental achievements work in conjunction with our Cloud Statistics (opens new window) service. When a player’s stats are updated, the Achievement service checks if the conditions for any incremental achievements have been met. If the conditions for achievement have been met the achievement will be unlocked. Here are a couple of examples of incremental achievements:

  • Collect 10,000 gold In order to unlock packs of bullets, a player must collect 10,000 gold.
  • Collect 100 items To unlock the Collector trait, a player must collect 100 items.

# Non-Incremental Achievements

Non-incremental achievements don’t require a goal value to be hit, and as such do not need to be integrated with the Statistics service. Here are some examples of non-incremental achievements:

  • Play your first game To unlock a bundle of weapons, a player must play the game.
  • Kill 25 thieves in a single game To earn their first medal, players must kill 25 thieves in a single game.

# Prerequisites

You’ll need the statistics code you created earlier when you fill in the configuration form.

# Permissions

You will need to create a Statistics (opens new window) configuration as the statistic code will be used when you create an Incremental Achievement.

    The Goal Value should not exceed the Max. Value defined in the Statistic Configuration.

    • Input the Tag field with contextual information related to the achievement. You can input up to five tags. This field is optional.

# Implement Achievements with the Client SDKs

# Unlock an Achievement

There are two ways to unlock a player’s achievement: either from Game Client or from the Game Dedicated Server.

Unlocking an achievement from the server is usually done after a match is completed.
