2019-11-30 Fix an injectivity issue with saving the gameGriffin Smith2-18/+33
Fix an injectivity issue with JSON-encoding the entity map that was causing the game saving to not properly round-trip. As part of this, there's a refactor to the internals of the entity map to use sets instead of vectors, which should also get us a nice perf boost.
2019-11-29 Use menus for combat and picking up itemsGriffin Smith2-1/+57
Refactor a bunch of stuff around to allow for polymorphically surfacing an EntityChar for all entities, and use this to write a generic `entityMenu` function, which generates a menu from the chars of a list of entities - and use that to fully implement (removing `undefined`) menus for both attacking and picking things up when there are multiple entities on the relevant tile.
2019-11-29 Implement saving+loading the gameGriffin Smith1-2/+13
Implement ToJSON and FromJSON for all of the various pieces of the game state, and add a pair of functions saveGame/loadGame implementing a prism to save the game as zlib-compressed JSON. To test this, there's now Arbitrary, CoArbitrary, and Function instances for all the parts of the game state - to get around circular imports with the concrete entities this unfortunately is happening via orphan instances, plus an hs-boot file to break a circular import that was just a little too hard to remove by moving things around. Ugh.
2019-09-29 Gormlaks attack backGriffin Smith2-0/+8
When gormlaks see the character, they step towards them and attack dealing 1 damage when adjacent. Characters have hitpoints now, displayed at the bottom of the game screen, and when the game is over they die.
2019-09-28 Implement the start of creature AIGriffin Smith2-14/+42
Add a Brain class, which determines for an entity the set of moves it makes every step of the game, and begin to implement that for gormlaks. The idea here is that every step of the game, a gormlak will move towards the furthest-away wall it can see.
2019-09-20 Add the beginnings of a prompt systemGriffin Smith1-14/+13
Add the beginnings of a generic prompt system, with exclusive support atm for string prompts, and test it out by asking the character for their name at startup
2019-09-19 Add items and inventoryGriffin Smith1-1/+8
Add a new "Item" entity, which pulls from the previously-existent ItemType raw, and add a "PickUp" command which takes the (currently *only*) item off the ground and puts it into the inventory.
2019-09-15 Progressively reveal the map to the playerGriffin Smith2-26/+106
As the character walks around the map, progressively reveal the entities on the map to them, using an algorithm based on well known circle-rasterizing and line-rasterizing algorithms to calculate lines of sight that are potentially obscured by walls.
2019-09-13 Place the chacracter in the level at startup timeGriffin Smith1-1/+1
Randomly select a position in the largest contiguous region of the generated level in which to place the character at startup time.
2019-09-09 Convert generated levels to wallsGriffin Smith1-1/+12
Add support for converting generated levels to walls, and merge one into the entity map at the beginning of the game. There's nothing here that guarantees the character ends up *inside* the level though (they almost always don't) so that'll have to be slotted into the level generation process.
2019-08-31 Add entities, and allow walking aroundGriffin Smith1-0/+141
Add support for entities via a port of the EntityMap type, and implement command support starting at basic hjkl.
