+this year for roguelikedev does the complete tutorial, i'm following along with thebracket's [_roguelike tutorial - in rust_](https://bfnightly.bracketproductions.com). for most of the 8 weeks, i'll probably just be working through the content rather than diverging too much into doing my own thing, since it's lengthy and i'd rather finish in time. that said, the ultimate aim here is to strip out the vast majority of the existing entities and replace them with my own, using the systems and components from the tutorial as a jumping-off point for something of my own making.
+
+i'll try to remember to update the web version on my page at the end of every week

-- not a whole lot
-  - busy week for me, so the only things i managed this week were finishing up some small things from the previous week. i started on combining logs that happen on the same tick (You hit the goblin. The goblin hits you.), and fixed up the _chance to spawn a guy each turn_ system to work with the groupsize flags, so there's a chance to spawn a pack of creatures each game turn rather than packs only spawning on map generation.

-
-- visuals (contd.)
-  - i'll start here, because it pretty much shows all the other things i did this week in the one image. the biggest change is nixing the rainbow colours i did in week 4 - having all the names on the sidebar and inventory be coloured by the colour of their glyph made for a difficult to parse ui. i swapped everything out for being coloured by their rarity (white for common and nonmagical items, grey for unidentified, and green-to-gold for uncommon-legendary rarities), and decided to add the glyph of the entity beside the name. overall, a big win i think. it provides more information more cleanly.

-
-- backtracking
-  - short and sweet, maps are persistent now. entities don't get deleted when you descend, they just get frozen, and you can return anytime. stair-dancing is a thing now, and something i haven't decided how to handle yet.
- 
-- item identification (no BUC yet!)
-  - unique schemes for unidentified items in the big categories (i.e. "effervescent green potions", "octagonal wands", and "GIB BERISH scrolls"), as well as the option of defining one-off obfuscated names for special cases
-
-- encumbrance
-  - varying levels of being overweight, with the limit determined by strength, slowing entities down by ~25% per level over unencumbered. right now it's pretty forgiving, and i'd probably like it to stay that way. my ideal balance here would be roughly how it ends up in 5e DnD: everyone can carry a good supply of consumables, but strength characters usually don't carry a much higher quantity of items than anyone else, because the strongest armour is extremely heavy. sort of like a soft strength requirement for the heaviest gear - rather than requiring specific stats or levels to equip it, it's heavy enough that you need to be strong to lug it around. but if someone weaker wanted to, they could, they'd just have to leave some other items behind to do so. or take the speed penalty for being encumbered

-
-- character creation!
-  - it doesn't look too pretty yet, but i managed to get it done in time. classes and ancestries are selectable, with ancestries determining some intrinsic bonuses (dwarves are hardy, catfolk are fast and have claws, etc.) and attribute maximums, and classes determining starting equipment and the actual attribute rolls. along with this, i expanded entity reactions - now a shared ancestry is taken into account first of all, and it checks faction if it doesn't manage to find anything. this means humans wont attack other humans, dwarves wont be attacked by gnomes and other dwarves, etc.

-
-
-- proper identification and beatitude
-  - item-ID is split from beatitudes as it should be, scrolls of identify and remove curse are in, and blessed/cursed effects are applied for a bunch of things.
- 
-    ![beatitude/buc](https://github.com/Llywelwyn/rust-rl/assets/82828093/387a9be4-225b-4b63-b9be-086973feb5ed)
-
-
-- better AI
-   - straight from thebracket, with a handful of tweaks of my own, i've finally atomised AI into adjacent, visible, chase, flee, and default systems. most notably,rather than hostile mobs attacking everything and passive mobs doing nothing, every mob has a faction, and most mobs have an ancestry. like mentioned above, mobs will take all this into account when determining how they want to react to any other entity. i see a lot of places to expand on this in the future, like going into alignments and other increasingly-specific reasons why any entity might want to murder another. or make friends with them. taming comes to mind here.
- 
-- an effects system
-  - instead of randomly doing things all around the codebase, everything is in the process of being moved over to an effects system. to put it very simply, there's a big list of every effect that needs to take place on the next tick, and each tick the queue is iterated through, the next effect is checked against a list of every entity that died this turn to make sure that it should still take place (no dead mobs still getting their attacks off), and then it makes the event happen if appropriate. if not, it just gets tossed out. it's all super modular, so effects can pretty much be applied to everything. the same damage and targeting effects work for item use and traps going off, or an entity swinging their sword, for example. i made use of this new system by adding in some aoe scrolls, like mass function and mass healing. see below for blindness improving telepathy range, and nice new particle effects.

-- **overmap**: bare, but exists. player now starts on the overworld, and can move to local maps (like the old starting town) via >. can leave local maps back to the overmap by walking out of the map boundaries.
-- **intrinsics**: speed, regeneration
-- **damage types**: immunities, weaknesses, and resistances
-- **full keyboard support**: examining and targeting can now be done via keyboard only
-- **a config file** read at runtime, unfortunately not compatible with WASM builds yet
-- **morgue files**: y/n prompt to write a morgue file on death to /morgue/foo.txt, or to the console for WASM builds
-- **dungeon features**: just the basics so far. a grassy, forested treant room, some barracks, etc.
-- **named maps**: "Town", "Dungeon"
-- **map messages/hints**: "You hear <...>."
-### changed
-- **colour offsets** are now per-tile (and per-theme) instead of +-% globally. i.e. varying fg/bg offset on a per-tiletype basis
-- **chatlog colours** are now consistent
-### fixed
-- negative starting mana
-- status effects only ticking if mob turn aligned with turnclock turn
-- map params not being saved on map transition
-- mob turns not awaiting the particle queue (mobs moving around mid-animation)
-- mobs not re-pathing if their path was blocked, causing traffic jams

-DETERMINING IF AN ATTACK HITS OR NOT:
-
-1. Whenever someone makes an attack, a flat 1d20 attack roll is made.
-2. A target number is generated, depending on the mode of attack, made
-   up of some combination of the following:
-        - ATTACKER'S HIT BONUSES:
-            - level
-            - any relevant str/dex attribute bonuses
-            - any relevant skill modifiers
-            - any to-hit modifiers from equipment
-            - any to-hit modifiers from status effects
-        - DEFENDER'S ARMOUR CLASS*:
-            - base armour class
-            - any relevant skill modifiers
-            - any ac modifiers from equipment
-            - any ac modifiers from status effects
-        - MISCELLANEOUS MODIFIERS:
-            - melee attacks always have a +1 bonus
-            - monsters gain a +10 bonus to-hit players
-3. The attack roll is compared against the target number.
-4. If the attack roll is less than the target, the attack hits.**
-5. If an attack hits, it deals:
-        - a roll of the weapon's damage die
-        - plus any relevant attribute bonuses
-        - plus any relevant skill modifiers
-        - MINUS a roll of the defender's AC, if the AC is negative.
-
-notes
-    * when AC is less than 0, it is treated as a random number from -1 to the value. e.g. -10 AC could be anywhere from -1 to -10.
-    ** functionally identical to rolling 1d20 + to-hit, and needing to roll higher than the defender's AC. this system just ends up
-       being easier to work with when involving additional modifiers, as you don't need to decide if they're a to-hit bonus or an
-       AC modifier -- they just always get added/subtracted from the target number that must be rolled against.
-
-Simple example, with positive AC:
-- You have an AC of 4, and the monster has a +1 to-hit, with a 1d8 damage weapon. 
-- The monster must roll less than 10 (monster v. player) + 1 (to-hit) + 4 (ac) = 15 to hit you. 
-- The monster has a 70% hit chance.
-- It rolls a 12, which is lower than 15, so it hits.
-- It rolls 1d8 for damage, and gets a 6.
-- You take 6 points of damage.
-
-Complex example, with negative AC:
-- You have an AC of -14, and the monster has a +3 to-hit, with a 1d8 damage weapon.
-- The monster must roll less than 10 (monster v. player) + 3 (to-hit) - 1d14 (ac) to hit you.
-- At best (AC rolls a 1), the monster must roll less than 12 to hit you. 55% hit chance.
-- At worst (AC rolls a 14), the monster must roll less than -1 to hit you. Impossible.
-- It rolls a 9, and your AC rolls a 2. 9 is less than 11 (10 + 3 - 2), so it hits.
-- It rolls 1d8 for damage, and gets a 6.
-bloodstains: if starts on bloodied tile, remove blood + heal, gain xp, grow (little dog -> dog), etc.
-- You have negative AC, so you roll 1d14 for damage reduction, and get an 8.
-- The total damage is 6 - 8 = -2, but damage can't be negative, so you take 1 point of damage.
-
-tl;dr
-1. Lower AC is better
-2. Aim for 0 AC - it's an important breakpoint. Every point of AC before 0 counts for a lot.
