Fixed a bug in the NPC magic casting that would have them failing to cast a spell due to async loading

Added in a check to make sure the NPC doesn't play a spell anim montage while already playing another.

Added in a Boolean called SpellLoading to the MagicComponent to help us with execution flow when NPC attempts to cast spells.

Fixed a bug in T_GetHealingSpell task where it would never finish execution

Fixed a bug where noise events were always coming from the player inside of magic effect components even if it was a spell the NPC had cast. This was causing the NPC to evaluate noises even if they were the one making them.

Fixed a bug where NPCs were completely ignoring spell cooldowns. Spell cooldowns were only being calculated for the player on the magic effect component, but the player doesn't even use the magic component.

Changed the try to heal code so that if the NPC is in combat they will try to heal if their health is below a random float between .5 and .8, if they aren't in combat they will always try to heal to 100 percent.

Fixed a bug where NPC spell actors would never be destroyed.

Fixed a bug that would prevent NPCs from being able to cast projectile spells due to async loading

Added in a new check in the cooldown system that multiplies the cooldown time with a value based on the skill of the NPC with that school of magic, basically if an NPC is really good with destruction that can cast more fireballs faster.

Fixed a bug of projectile spells not detaching from the NPC hand sometimes.

NPC spells now have their accuracy effected by their skill in the selected magic school of the spell.

Removed a weird phantom reference to the combat status component from the Melee component.

Removed all the references to the equipment component from the melee component.

Created a new interface event for UpdateMovementSpeed previously this was handled inside the movement status component, it still technically is for now but its activated through the npc via the interface event now instead of a hard ref.

Removed all the references to the Movement Status component from the melee component

Removed all the refs to the UBPP library in the base object

Optimized the tri count of the SKM_Manny Tester hand that was referenced inside the base object

Further reduced the Base object down to 33.8mb

Fixed the bug of the health bar widget never updating.. kind of, its the same damn bug we've had for a but with things not being flagged as rendered by the engine.

Removed all of the old combat testers from the BP_AI_Parent.

Created a new Interface "BTGS_NPC_HUD_Interface" so we can update NPC hud values without direct casting.

Fixed a bug where a recovered arrow would never despawn.

Fixed a Null reference bug in the new blocking code

Changed the name of the AttemptHeal_OnInterface event to AttemptToHealViaItem_OnInterface for better clarity. Also fixed a bug in it that was causing a null ref on a destroy actor command because we were using a ref to the spawned potion, but if the npc didn't have any potions that value would always be invalid, we now check first to see if the array of potions is valid.

Renamed the AI Task T_AttemptHeal to T_AttemptHealViaItem for better clarity.

Moved the CalculateLuckChance function from the BP_AI_Parent to theStats component

Replaced all references of the old CalculateLuckChance function inside the NPCs to the new stats CalculateLuckChance

Added a new calculation to the decorator in the AI tree called D_Should_Attempt_To_Heal, we now have a random check based on the npc intelligence and luck instead of just a random bool.

Added a new check to the task T_AttemptToHealViaItem. We now check the NPCs luck and Alchemy skill level to determine if they can attempt to heal via a potion.

Added a new check to the task T_GetHealingSpell. We now check the NPCs luck and Restoration skill level to determine if they can attempt to heal via a spell.

Fixed several bugs in the Task T_GetHealingSpell where the task would never end.

Fixed a bug in the function library where spells weren't properly found in the data table.

We have two events called SendMagicSpell one in the magic component and one inside the bp_ability parent so i renamed the one inside the magic component to SendMagicSpellInMagicComp

Started Tracking down why the npcs sometimes cant heal, gonna have to tackle this tomorrow.

Work Log 9/2/2025

Demoed how to do a level block out for Megan for her class.

Started work on cleaning up new player blocking code, haven't touched it since I got it working

Found a bug where the players overlap check timer was never being turned off could have killed performance later

Created an Enum for block proxies so we can use it inside the new function i created inside the BTGS_interface for toggling the collision for the block proxies on the BP_AI_Parent.

Reduced the size of the base object from 162mb to 51mb by removing old hard references due to the NPC blocking code rewrite.

Removed the base objects dependency on the combat status component

Created a new interface event to pass the status of if an NPC has drawn their weapon. We were previously calling for the Combat status component whenever we needed this, but that was messy at best and buggy at worst. This new event should allow cleaner checking and help solve some of our combat bugs notably the one where npcs can attack even if they have no weapon in their hand.

Removed the old exposed transforms that were added to the NPCs during the new block system development

Removed the dependency of the narrative base npc to the lyra anim bp.

Further reduced size of base object to 37 mb by removing hard refs inside of the melee component which itself saw a reduction from over 30 mb down to 6mb

Replaced all of the checks for weapon drawn inside of the melee component with the new interface event GetWeaponDrawnStatus.

Removed all of the references to the combat status component inside of the melee component.

Jackie found a bug in the arrow outline system. If you drop an arrow the outline stays there, so i fixed that.

Upon further inspection it looks like the same issue exists if you a drop bow the arrow outline stays, fixed that too.

Spent 3 fucking hours on figuring out why if you recovered an arrow from the world it couldn't be reused it would just sit there in the air after being fired. Turns out that you have to manually deactivate the projectile component after an impact, just reactivating doesn't work which seems like an engine bug to me.

Moved the arrow variable resets to a separate function inside the arrow component instead of a bunch of sets inside the base object

Fixed the metal sound that was playing when an arrow hit stuff instead of a wooden one.

Work Log 8/29/2025

I’m back from a well needed vacation. Still Feeling pretty exhausted though frankly.

Added time dilation back to fired arrows, this worked at some point, but was never programmed properly.

Set the arrow time dilation chance to be relative to the players block skill

Moved the sound spawning and destroying for the time dilation effect to the player character in a unified function instead of it being scattered throughout different components

Fixed the arrow ricochet bounce angle it was far too low previously

Added a max number of bounces that an arrow is allowed to have currently set at 4

Added a check to check if a fired arrow is hitting another weapon that is NOT a shield if it is we should try to ricochet it if its a shield we should follow normal angle calculations for arrow ricochet or sticking.

Added the ability for players to have a chance to recover fired arrows from the world

Added an outline to where arrows go so the player can better understand where to put notch arrows on the bow. This should solve all the problems early testers have had in trying the archery system.

Work Log 8/23/2025

Fixed a bug in the drop sound event and metasound that as causing the sound to only ever spawn at the initial spawn location.

Fixed a bug where the fail hit sound would never reset

Fixed a bug where the npc would try to play the blocking animations even if their weapon wasn't drawn

Fixed a bug where the SpawnAndPlayFailedHitSound wouldn't trigger a noise event

Added a noise event to when the player hits an enemy that isn't yet aware of them, Theoretically we would just give the impact point for the noise location but that didnt seem to work so we are gonna give some radius around where the player is for the npc to look what hit them, in testing worked pretty consistently and felt natural enough.

Fixed bow and arrow damage calculation, was previously only using bow value for damage oddly enough you would figure it would only be using the arrow damage if anything, but nope Nathan programmed that wrong, all good though simple mistake.

Removed the line trace we were doing to determine arrow damage in the arrow component seemed pointless seeing as we are now using actual hit events for everything.

Fixed the Bug of the arrow trails staying around forever if you hit a close enemy

Fixed the bug of the arrows spinning forever if you hit a close enemy

Massively cleaned up Arrow Code

Fixed the math and code for sticking arrows into objects physically, previously the arrows just kinda sat near the surface where they hit now they stick into the object they hit properly and even have a bit of randomization for how far they will stick in, might want to later make that randomness based on arrow velocity somehow, but works well enough for now, looks great!

Arrows are properly activating their hit particle effect when hitting not character targets

Work Log 8/22/2025

Set up the other 3 displays today which took 3 fucking hours for some reason, the displays were being super fucky and the new monitor mount doesn't provide enough swivel really annoying.

Found a pretty large bug in how durability and item health were being calculated, so i completely rewrote that functionality.

Moved all of the armor durability calculations into functions and loops instead of the giant functions we were using.

Work Log 8/21/2025

Added noise events to spell hits just like the noise events for dropping or hitting weapons together.

Removed the on event overlap code from the base object as we no longer use it for combat hit checks.

Spent 5 fucking hours tracing down a Niagara crash issue for the blood effects, but at least we now have 18 different blood effects when you hit someone. I really kind of hate niagara as well, sure its powerful, but we have SO MANY crashes with it. That being said its clearly my weakest area of Unreal Engine expertise, I should spend some time making some complex stuff with it.

Work Log 8/20/2025

Built the new monitor stand today to support the new 4k 144hz HDR monitors, i have 2 of them right now 3 more should be here tomorrow.

Renamed a few of the events in the melee component for clarity. The melee component ever only exists on NPCs so the events there center around the NPCs doing something like NPC attack blocked, NPC Start Blocking etc

Fixed a bug where shield bashing would only ever play the anim once

Added some code to differentiate which sound and particle effect to spawn when npc blocks based on whether or not they are holding a shield.

Fixed some incorrect references in the base object combat code.

Collapsed the code for spawning an item drop sound into a function

Added an array of sounds for metal clangs to make the MS_ParrySound Metasound more random we were previously only playing a single sound effect inside the meta sound when a parry happened, i plan to also use this sound for general weapon hits like for if you are holding two weapons and hitting them together, previously we were using the hit sounds for this, but that doesn't really make sense seeing as those are a bit meatier.

Scratch that. Cant use the parry sound for the player just hitting two held weapons together sounds fucking weird, besides the parry sound should stay specialized as it is. So i created another metasound thats the same base sound as the parry sounds but with reverb and non of the extra effects that make up the parry sound effect.

Found a bug in Gabriel's metasound design. He was sometimes using (Trigger Accumulate) to kill the metasound in locations where the full accumulation never would have happened, the node he should have been using was (Trigger Any)

Added a shield hit sound array to my new PlayerHitWeaponsTogether Metasound

Removed some code in the Melee component function EnemyBlockHit that would sometimes lead to a dead end causing the NPC to neither block or parry.

Fixed an audio bug related to dropping weapons. they would previously play a sound for if they hit something like the floor, but if they hit another weapon that had previously been picked up and dropped it wouldn't make the sound for hitting another weapon.

Added a Do Once gate to the item drop sound also pushed it into a sperate event thats resettable so we can better control how that sound effect plays and stop sound spam

These new weapons sounds now report noise events so if players are sneaking around, but then decide to start banging their weapons together it will alert NPCs.

Dropped weapons and other items also produce noise events meaning you can actually throw something to distract an npc now if they haven't detected you, pretty cool.

Work Log 8/19/2025

With the help of Jackie I fixed the hit reaction animations being too long

Generated some new temp lines for combat barks

Made another dialogue for combat taunts used for things like when the npc blocks your attack

Cleaned up combat code in melee component event graph for parrying blocking and attacking

Added a Boolean blend inside the anim graph for whether or not we should be playing blocking anims with a shield or not

Work Log 8/18/2025

Had to fix a bunch of issue related to the codex not properly uploading to GitHub. I kinda fucking hate GitHub in my opinion its only useful for toy projects that don't have tons of data. I am aware that most of the world uses it for software development… I think that is a mistake.

Got Megan's computer set up to be able to package to android, always a fucking nightmare to get android setup to package to a headset even though i've done it dozens of times at this point.

Put in some error handling code for dealing with NPCs trying to initialize dialogue when the didn't have an NPC data ref

Removed refs to the Hair and beard meshes on the BP_AI_Parent because they are removed well before the could be used. These were causing log messages about invalid refs.

Added refs to weapons to the events for parrying and blocking that way we can choose what type of sound to play when we impact for a block or parry instead of it being hard coded

Added a recoil state to the animation graph for NPCs so they can properly respond to having their attack blocked.

Added an interface event called PassWeaponOwner_OnInterface to allow us to get a direct reference to who ever is using a weapon

Parrying and Blocking are now programmatically different blocking plays one set of sound and animations and parrying plays another

Shield bashing now has a chance to knock down an NPC, one of my favorite feature adds, just feels awesome in VR.

Updated the stunning functionality to make sure the npc stops strafing around the player when stunned

Added hit reactions to the anim graph they aren't perfect yet need Jackie to modify the length of the animations they are far too long and reset the npc to a neutral pose for like half a second before they go back to fighting looks super weird

Added a check to make sure npcs cant attack when they are stunned

Added a check to make sure we can still knock down npcs, if we shield bash an npc and it knocks them down we ignore hit reaction animations.

Work Log 8/15/2025

Interviewed a prospective hire today for a new narrative writer, took most of the day but went well.

Work Log 8/14/2025

Worked on combat code, blocking is much more reliable now, we have a block proxy set up for the top and bottom of the npc, if the player is faster than the block animation then they still get blocked if the npc has chosen to block.

Ai strafing around the player during combat works again!

Implemented a new selection thing for the npcs determining if the player is using a ranged weapon or melee weapon, similar to how they know if another npc is using ranged or melee.

Distance checking for blocking is now enabled, meaning the npc shouldn't fantom block when the player isn't even nearby

Fixed doors not closing

Fixed players taking forever to die at the end of the matches

Updated the weapon broken event to auto add the broken item to the inventory so the player wont be confused and continue to try to use it

Put in a temporary workaround for the two handed weapon blocking not really working with the new block system, if the system sees that the npc is using a two handed weapon it plays the two hand block instead of the normal block animations.

Tutorial is playable all the way through again

Temporarily fixed the weird issue with arrows freaking the fuck out when you pick them up turns out that only happens when they spawn from a quiver, its something wrong with their collision that i haven't quite solved yet, changing the response to the player channel seems to make no difference even though thats how non spawned arrows handle it. for now we just check to see if the owner and the hit thing is the player character if it is we ignore hits, bad for perf sure but works for now.

Work Log 8/13/2025

Worked on administrative stuff like the new list, codex stuff.

Worked on the blocking system we have a tentative solution to the issue of weapons not hitting if moving too fast.

Work Log 8/9/2025

More work on the crowd rendering system, ran into some issues with how PSO caching was handling the crowd actors, forcing them to always use the lowest lod even though im custom calculating the lods.

Crowd rendering system is working pretty well still needs to be instanced, but the actual rendering is doing fine the textures are a bit aliased at a distance, but id rather that than blocky blurry messes.

Work Log 8/8/2025

Spent the time since the last update working on the crowd system. Who would have though rendering 4k NPCs on a mobile chip would be hard.... Havent really taken a day off in a couple weeks, but theoretically I have a usable solution now all built in house too which is cool!

Readded the sky actor for the tutorial arena level

Had to rebuild the whole tool for generating the crowd npcs to use a editor utility widget instead of an editor utility actor

Generated around half of the animation texture arrays

Work Log 7/29/2025

Tried to compile to the headset and what a surprise Skelot is a piece of shit that crashes the build every time.

Tried switching back to 5.5 main branch for testing and now narrative wont work. Fuck.

Our crowd system is super important, I feel like this is gonna take some time to solve and a lot of R&D. All the plugins we have tried have not worked in one way or anolther. Might have to build something custom.

Work Log 7/22/2025 - 7/28/2025

Worked on the blocking system its working, but not perfectly. Feels like one of the hardest god damn problems of my career frankly.
