Achievements are awarded to the player when they meet a certain goal, and optionally give some benefit.
You can make global achievements by putting them in a side layer by making its row equal to "side" instead of a number.
Useful functions for dealing with achievements and implementing their effects:
Achievements should be formatted like this:
achievements: {
11: {
name: "Blah",
more features
},
etc
}achievements: {
11: {
name: "Blah",
more features
},
etc
}Usually, each achievement should have an id where the first digit is the row and the second digit is the column.
Individual achievement can have these features:
name: optional. displayed at the top of the achievement. The only visible text. It can also be a function that returns updating text. Can use basic HTML.
done(): A function returning a boolean to determine if the achievement should be awarded.
tooltip: Default tooltip for the achievement, appears when it is hovered over. Should convey the goal and any reward for completing the achievement. It can also be a function that returns updating text. Can use basic HTML. Setting this to "" disables the tooltip.
effect(): optional. A function that calculates and returns the current values of any bonuses from the achievement. Can return a value or an object containing multiple values.
unlocked(): optional. A function returning a bool to determine if the achievement is visible or not. Default is unlocked.
onComplete() - optional. this function will be called when the achievement is completed.

textStyle: optional. Applies CSS to the text, in the form of an object where the keys are CSS attributes, and the values are the values for those attributes (both as strings).
layer: assigned automagically. It's the same value as the name of this layer, so you can do player[this.layer].points or similar.
id: assigned automagically. It's the "key" which the achievement was stored under, for convenient access. The achievement in the example's id is 11.
goalTooltip: optional, deprecated. Appears when the achievement is hovered over and locked, overrides the basic tooltip. This is to display the goal (or a hint). It can also be a function that returns updating text. Can use basic HTML.
