Important Functions

Name of the most important functions, their parameters, and what they do.

• func make_new_level(name: String) -> void: Create a new level with the given name in the levelPath folder.

• func export_level(tileSet: TileMapLayer, playerData: Panel, worldSize: Vector2) -> void: Exports the current level using the tileSet, with any specific player changes using playerData, and the world size using worldSize. Tile data is stored in a CSV file, while player data is stored in JSON.

• func import_level(tileSet: TileMapLayer, playerData: Panel, directory: String) -> int: Imports a level from the given directory to the tile map using tileSet, along with the player data from playerData. Tile data is grabbed from a CSV file, while more in-depth data, such as the player information, is taken from a JSON.
