Achievements
wesnoth.achievements.set
- ♟ wesnoth.achievements.set(content_for,id)
Sets the specified achievement as completed. Unlike the [set_achievement] tag, this does not display a popup.
- content_for: The [achievements_group] that this achievement is part of.
- id: The id of the achievement.
wesnoth.achievements.has
- ♟ wesnoth.achievements.has(content_for,id) → achieved?
Returns whether the specified achievement has been completed.
- content_for: The [achievements_group] that this achievement is part of.
- id: The id of the achievement.
NOTE: This is not safe to use in online multiplayer since different players can have different achievements completed. As such it will always be treated as if the achievement is not completed.
wesnoth.achievements.get
- ♟ wesnoth.achievements.get(content_for,id) → cfg
Returns the contents as described for the [achievement] tag, as well as the additional current_progress attribute. If a progressable achievement is completed, current_progress will be -1. If this is not a progressable achievement, then current_progress and max_progress will both be 0.
- content_for: The [achievements_group] that this achievement is part of.
- id: The id of the achievement.
NOTE: While this can be used to retrieve the achievement's actual achievement status for a client in online multiplayer, this is also not safe to use in that situation for the same reason.
wesnoth.achievements.progress
- ♟ wesnoth.achievements.progress(content_for,id,[amount,[limit]]) → number
Progresses an achievement by amount up to either the achievement's completion or limit, whichever is smaller, and returns the new current progress of the achievement. If the achievement's current progress is already above limit, then it remains unchanged.
Both limit and amount are optional. If a limit is not provided, then the achievement is allowed to progress until it is completed. If both are omitted, then the achievement is not progressed and it simply returns the current progress of the achievement. The return value can have the following values:
- 0 or higher: this is the achievement's current progress.
- -1: this achievement is already completed.
- -2: an error happened, check your log file. This can happen if the achievement wasn't found, its achievement group wasn't found, or if this achievement does not have a max_progress value set.
NOTE: The achievement's current progress returned by this function is not safe to use in online multiplayer for the same reason that wesnoth.achievements.has and wesnoth.achievements.get are unsafe.
