Ill probably be using this on a new playthrough, curious though, is the damage enemies take about the same as the player (same HP and same defense system)? It's the one thing that irks me with some mods when i need to unload into an unarmored bandit but they can 2 shot me with a MP5. I don't mind dying fast but i want it to be fair :P

I tried to do this (and I do my best to) but it's impossible to achieve a game 100% accurate in terms of damage of player and NPC.

Players use armor, has bleed and are affected for environmental damage, NPC not. NPC has parameters analogue to player armor but its different. The appearance of NPC don't mean that NPC was using that armor or has that defense but it's indicate the rank of this NPC.

For example, if you see a exoskeleton it's not mean that NPC was using exo but its mean that NPC has a high rank and probably his defense attributes has high values.

For this reason is impossible to make NPC 100% equal player unless someone remake NPC system to make his resistances equal (in terms of values) player armor but it's possible in actual game to pass the impression of NPC having that armor, and that was what I tried to do.

I see this bug occur with Dodge these Gnomus scopes if I use texture detail in 50% or below. Try increase texture detail bar above 50%. (put the texture detail in max config and reduce texture quality until the bug occur again to know the "sweet spot" for this configuration).

If it's not work, try to reinstall the pack without Gnomus scopes. (you can continue your saved game normally)

Hey, Marked One -- interesting compendium of tweaks you got there! (/Sidorovich) ;D

I've noticed what appears to be a typo in the hardcore_AI_aim script on line 17:
you have " hardaim_initvalinitval = false " when (I believe) it should just be " hardaim_initval = false "

Note: I haven't loaded your tweaks yet, I was looking at various hardcore AI aim fixes since I just discovered that hardcore AI aim doesn't actually work in 1.4.22, lol! :D

Thanks for the warning, I revised the file and uploaded it again.

Unfortunately my vacation is over and I'm back to work and for this reason the development of this pack will be slowed.

About the hardcore AI Aim, initially I mounted a script that set the values every load (function on_game_load()), the problem is, eventually these values are changed to default (and I don't know why). The solution that "ssregibility" found (and the reason that I use his script and not my own), he set the variables to adjust hardcore AI on first key press after game load, and remember, you need to press a button when load finishes.

With this workaround solution, even if the bug that sets the values to default on load occur, these values will be changed immediately.

I tried to read "enable_hardcore_ai_aim" variable in axr_options.ltx to enable/disable this script with config options using axr_main.config:r_bool_ex (like what I done with "enable_restrict_travel" on fast travel script line 206) but mysteriously the game crashes during load if I use it in hardcore AI Aim script.

Thanks for the info!
I've always had Hardcore AI Aim "on" in CoC's menu but I didn't know it wasn't working. Checking out your Zone Overhaul addon is actually how I learned about that, lol :D
Which led me to ssregibility's scripts. His AI_aim script is what I'm using now, with a few tweaks of course!

Both addons will conflict with this pack and probably will broke everything.

OA will conflict with all armor balance that I made because all armors were tweaked (even with simplified armors because I used the armor base of CoC vanilla).

Lost to the Zone will conflic with many other aspects like many combat stats (m_stalker.ltx for example) and many items (artifacts, quest items and consumables).

In other words, install any of these addons on this pack will break your game. Sorry.

Sure, you need to edit one ltx file in "gamedata\configs\weapons" but witch file I can't tell because depends of mod that you're editing.

In vanilla game the file is "weapons.ltx" and in AO the file is "weapon_ammo.ltx".

Basically, to discover witch file to edit, enter in "weapons.ltx" and search for the files with "#include" and search witch file is the correct (sorry but there no easy way to do this).

When you discover the file that store the ammo information, search for the ammo type that you want to edit (for example the russian 9mm called "ammo_9x18_fmj" for normal version or "ammo_9x18_pmm" for hollow point version). On the section of your ammo, search for the variable "inv_weight". This variable say to game the weight of full ammo box of this ammo type in kG, just change this value to change the weight of your ammo.

The box size can be found in "box_size" variable of the same ammo and editing this value changes the ammo weight too because each bullet weight is calculated dividing "inv_weight" for "box_size", but, changing "box_size" will change the ammo price too because the cost is calculated over the box size like the bullet weight.

So I've been playing a bit, and the Search and Rescue missions from npc's causes a crash everytime you tell the hostage to come with you, it dings the mission updated then crashes (unhandled exception). I'm not sure why this is happening, but the only way out of these missions seems to be to fail them. Any idea for a fix? I don't have any other modifications installed or modification to files, just straight from your overhaul zip.

Sorry for the long time, this bug is really hard to replicate.

On this addonpack I don't modify any quest related aspect of the game, for this reason this bug certainly exists in vanilla.

In my tests the bug occur when you get a rescue mission, the quest receiver die and the game fails to register the mission failure due his death. When this occur, when the mission updates (usually when you get the hostage) the game crashes.

I think, the cause of register failure is Alife simulation enabled to entire map (this is the only possible modification that can cause the problem).

Unfortunately i don't know how to solve this problem in a save, but, to prevent the bug, I think the way is to disable the full Alife simulation by deleting the "_g.script" in "gamedata\scripts". It will cause the game to load the default "_g.script" that will limit the Alife simulation to your map and linked maps (other positive side effect disabling this is, it will increase the game performance).

Obs.: I,ll put the "full Alife simulation" as install option on next update (like the gnomus scopes) because it's causing more problems than advantages.

Very strange, this script only check (with these option enabled) if the player is overload, if the player still in combat (with an enemy seeking for him), if there a psy storm/emission or if the player still in a restricted area. There no check for equipped/acquired artifact.

Can you inform more details about the message ? Like possible other installed addons, location that it's occur and exact message displayed when you try to fast travel ?

Initialy I'll write here how to solve the compatibility issues with Dynamic HUD, but I prefer to update the addon pack.

Now, answering your questions:
1 - The updated pack include a file that solve the compatibility issues with dynamic HUD addon. I create this solution because Dynamic HUD represents part of the play style that this addon pack represents and some people maybe want to include in their game.

2 - Unfortunately TRX addons are much more complex and I cant grant compatibility with. I do not include this in original pack because it's changes the game drastically and the objective of this pack is to preserve the feel of the vanilla CoC (except for the addition of AO and the re-balance of combat and economics).

Try to test possible compatibility with your favorite TRX addons and feel free to ask for help here. If I can solve any problem I'll help. Unfortunately I'm too busy these days to check the compatibility with these addons (this process involve much tests and I'm out of time due my work).

Reply Good karma Bad karma+3 votes

- DoctorX Dynamic Anomalies 2.1 [CoC 1.5 / 1.4.22] will work with no conflicts.

- DoctorX Dynamic Faction Relations 1.8 [1.4.22] will work normally but the modified PDA relations table will be overwritten by DoctorX version.

- DoctorX Questlines 1.25 [CoC 1.4.22] will work normally but the quest items change will be undone (the item's weight will be restored).

To use any of these mods, DO NOT INSTALL "Full alife simulation" and install DoctorX's addon after this pack (because DoctorX addons replace some files).

P.S.: I'm really considering completely remove "Full alife simulation". It's cause too many bugs with quests and other addons.

By my side there's no problem taking this script, but that's not all my work.

I used the pda_relations_tab:Reset() function from "[1.3+patch]pda goodwill display" for Last Day as base to this script and tweaked to compatibilize with CoC 1.4.22 and show exactly discount level.

Very nice overhaul, I can finally feel that my guns are actualy guns and I don't have to shoot a whole magazine to enemies heads to kill them.
But I think that the mutants are a bit too powerfull - what I mean is that i understand that for e.g. boar shouldn't die from one or three 5.56 shots to body but 2 or 3 shots in head should definitly kill it - and with this addon it sometimes takes over a half of rifle ammo magazine into body or over 5 shots perfectly to the head to kill most common mutants and with modified bleeding and damage it's almost 100% death when you accidentaly run into 3/4 boars with just m4 or you will waste all your ammo to kill it.

But other than that, great overhaul :)
Thank you.

I think you don't really understand what Hardcore AI Aim do.

This option don't increase the accuracy of enemies, this option don't increase the aim distance from enemies.

This option just adjust some values that make the enemies to aim properly at moving targets.

With default values (hardcore AI aim disabled), if you are in moviment, enemies will hit you only if you are running directly in their direction in straight line. Then, if you simply run (acquire "infinite" stamina is easy with low carry weight and some stamina artifacts), you can cross Pripyat without get shot even once.

Hardcore AI aim changes only factors that change abilities to shot moving targets and do nothing with aim range or anything else. If an enemy can snipe you, he will with or without hardcore AI aim and it's a vanilla CoC characteristic.

As the author says, hardcore AI aim doesn't make all enemies hitscan sharpshooters. Hardcore aim (when it's working*) just eliminates the built-in timing penalty that's applied to NPCs.
The problem you're describing happens when enemy NPC view settings and trigger settings are set too high so they can spot you from 300m away when you're standing still. :D
The funny thing is, the Hardcore AI Aim toggle has always been broken in CoP anyway, so you've probably never actually seen it in action. There's a fix for it on this site:

I have the following problem. I have CoC and this pack of addons. I installed DoctorX Questlines. I started as millitary and i am neutral to them. On the map and in person they are green(friendly) but my faction relation is 0 and they dont sell me armor which is a problem. I've been doing quests with them and i gain 25 or 50 increase. It will take me years until i reach the point of being able to purchase armor or suits from them. I'd appreciate a help or at least tell me which file to modify. I checked the file game_relations.ltx but i dont see anything that has to do with quests awarding more faction relation. Any help would be appreciated!

Only a caveat:
About the hardcore aim script from Last Day, it uses the wrong values, those in the script are actually the VANILLA ones, if you want to use the real, hardcore ones you might take a look to axr_main_options.script and look for the other values (those that begin with 0. Whatever) and use them to replace the ones in the hardcore aim script. You WILL notice the difference.

It's appear that you tried to install other version of Fallout mod over this pack. This mod becomes incompatible with this pack because it's already included (and modified) in pack.

This crash usually occur when you have two conflicting mods installed.

If you really do that, just reinstall the pack over a clean CoC 1.4.22 install and everything will be ok. You can backup the "appdata" folder and put it in your clean install to maintain your save files.

If it's not the case or if this procedure don't solve the problem, please give-me more information about your install. I need to know what mods you have and installation order.

Are faction defense characteristics something that also exists in the normal mod?

Reply Good karma Bad karma+2 votes

renard162 - - 57 comments

If you mean "original mod" as "call of chernobyl without addons", then, no.

In vanilla game you can get any armor in virtually any vendor, for this reason, each faction has no specific characteristic. And, even with different characteristics, all armors have similar effect and the mandatory attribute becomes armor and artifact slots (environmental defenses have extreme low impact over player play-style because anomalies are extremely easy to avoid and causes extremely low damage).

In CoC Overhaul, due the total damage re-balance, addition of chemical fallout and, recently, the addition of DRX dynamic anomaly, the armors became unique. For example, if you are using a duty armor (with extreme high combat defense but extreme low environmental defense), you'll get much less bleeding when hit but can die easyly passing over a "chemical mine anomaly" and your stamina will have a short duration running.

Otherwise, if you are using a freedom armor, with great "environmental defense" but lower "combat defense", in some situations you can face a chemical fallout directly without cover taking any damage but are much more exposed to damage/bleeding caused by mutants or weapons.

Playing with duty armors, player are much less artifact dependent (artifacts still important!), while playing with merc armor, if player don't get high quality artifacts, he'll be in serious disadvantage.

Playing with military armors, player probability will consume high amount of energy drink but have high combat defense, otherwise, playing with bandit armor, probably player even carry an energy drink.

But, to acquire the desired armor player have few options:
- Became friend with that faction;
- Kill many members of that faction and try to drop one of their armor;
- Find an armor in map (stashes never have armors, but there some on labs or NPP). (only few armors have this option)
