How to use

Achievements

To use your created achievements in your game is quite simple. You have 3 functions to use:

1. UnlockAchievement(achievement_id)

2. IncrementAchievement(achievement_id, steps)

3. ShowAchiements()

• To unlock achievement, you simply call uthGPGS.achievement.UnlockAchievement("id"); from engine. This also unlocks and makes hidden achievements unhidden.
• To increase steps in achievement that has steps, use uthGPGS.achievement.IncrementAchievement("id", steps); to progress achievement as many steps you want.
• To see all your achievements, simply call uthGPGS.achievement.ShowAchiements(); which will call built-in achievement viewer and pause your game activity.

Leaderboards

To use your leaderboard(s), you have 2 simple function to use:

1. SubmitHighScore(leaderboard_id, score)

2. ShowLeaderboard(leaderboard_id)

• Whenever you want to submit score to a certain leaderboard of your choice, simply call uthGPGS.leaderboard.SubmitHighScore("id", score);. However one player can only have one score on leaderboard. Submitting lower score than previous one does not update that players standings.
• To show leaderboard to a player, call uthGPGS.leaderboard.ShowLeaderboard("id"); to show built-in leaderboard viewer. This also pauses your game activity.
