Adding New Achievements

Using Existing Achievement Types

If you just want to add an achievement of a type that is already there, for example "collect a number of coins", create a new resource in the res://achievements/global or res://achievements/level/LEVEL_NUMBER folder.

Make sure to add the description to the localization file.

Adding A New Achievement Type

To create a new type of achievement, add a new script that extends the Achievement class:

extends Achievement
class_name PressStartAchievement

export(int) var keyToPress

Then add the logic to check if the achievement is met in AchievementGet.gd:

func check_achievements():
                   ...
		match achievement.get_script():
			CoinsAchievement:
				is_completed = coinsSinceStartingLevel >= achievement.coinsRequired
                   ...
			PressStartAchievement:
				is_completed = Input.is_action_pressed(achievement.keyToPress)

Now you can create new resources with this type as described in "Using Existing Achievement Types"
