Level structure

All level definition files and the level index file are located in the levels folder.

Level index

The index.json file holds an single array of strings, corresponding with the names of level definition files. The order of array elements defines the level order.

Level definitions

Each level consists of a .json file and a .clp file with the same name.

The .clp file simply holds the level's clips code.

The .json file has the following structure:

{
	"title":"The Hungry Tiger",
	"description":"The tiger is hungry! You have to feed it!",
	"goalStr":"Add `(is tiger fed)` to the fact table using only one assertion.",
	"successStr":"The tiger thanks you!",
	"goal":"(is tiger fed)",
	"tabu":["(is tiger fed)"],
	"limit":1
}

where

• title is the level's name
• description is the level's plot description (in markdown)
• goalStr is the level's goal description (in markdown)
• successStr is the text that is added after "level cleared!" (in markdown)
• goal is the goal fact
• tabu is a array of restricted facts. ? can be used as a wildcard, i.e. (is ? fed) and | can be used as or, i.e. (is tiger|wolf fed).
• limit is the amount of facts that can be asserted by the player. -1 for no limit
