Add a Wield command, which prompts for a wieldable item, if any, to take
out of the character's inventory and put in their right hand.
Eventually we should support other hands, but for now hardcoding the
right hand should be fine.
|
|
Split the character's inventory up into wielded items (in one or both
hands) and the backpack, and display wielded items when drawing the
inventory panel. Currently there's no way to actually *wield* items
though, so this is all unused/untested.
Also, add the ability for items to be "wieldable", which gives specific
descriptions for when attacking with them and also modified damage.

Rendering an editor with txtWrap makes brick blow up because editors
have an internal viewport, but txtWrap advertises an infinite width.
|
|
Add a very basic inventory panel to the game opened by pressing `i`,
which displays the contents of the player's inventory in a basic list.
|
|
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.
|
|
Implement the PointOnMap prompt type, which allows the player to move
the cursor around and select a position on the map, and use this prompt
type to implement a "look" command, describing all entities at the
selected position.
|
|
Wrap hitpoints in a newtype, and recover character hitpoints over time
|
|
Rather than blindly taking one entity from the list when we have
multiple entities on the same tile, add a `drawPriority` method to the
Draw typeclass which allows individual entities to request to be drawn
on top - this avoids the "noodles floating over your head" bug we saw
before.
|
|
Gormlaks now move 1/8th the speed of the character, which means we can
run away from them - yay!
Unfortunately this also introduces a bug where they'll eventually get
stuck and not do anything, so I'll be tackling that next.
|
|
Add menu support to the prompt system, and an "Eat" command that prompts
for an item to eat and eats the item the character specifies, restoring
an amount of hitpoints configurable via the item raw type.
|
|
When tracking message history, save messages associated with the turn
they were displayed on, which allows us to have the notion of the
"current turn's" messages (provided via a MonoComonad instance).
|
|
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.
|
|
Add a (debug) command to reveal all tiles on the game regardless of the
character's vision, which'll make it easier to debug creature's behavior
while they're not visible.
|
|
Add a Door entity and an Open command, which necessitated supporting the
direction prompt. Currently nothing actually puts doors on the map,
which puts a slight damper on actually testing this out.
|
|
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
|
|
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.
|
|
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.
|
|
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.
|
|
Implement a concrete "Creature" entity, and place one on the screen at
the game startup for testing.
This revealed a bug with drawing when getting the maximum entity
position, but that appears to be fixed now (yay)
|
|
Add a "previous message" command, triggered via ctrl+p.
I attempted here to get the message area to still take up a row of space
post-hiding the message, but failed - should revisit that at some point
|
|
Add a "say" function for saying messages within an app monad to the
user, and link everything up to display them and track their history
|
|
Add support for entities via a port of the EntityMap type, and implement
command support starting at basic hjkl.

Initial commit of a Haskell version of Xanthous, written using Brick and
built with Nix.
This is so much nicer and so much easier
