Modding existing weapons and ammo

[mimic]

Hi all,
first i want to say, since i tried SoC i fell in love with the game (even considering moving to prypiat and go live in the exclusion zone ).
now i installed CS with the 1.5.10 patch and was thinking, why not have a Saiga analog weapon.
Since i am new to modding, all i did was take the AK/74 and change the ammo it uses and make it so npcs don't use it to avoid having problems with npc trying to shoot 5.45mm out of a gun that uses 12gauge shot.
but i feel the gun has not enough power, needing 3-5 shots to kill a renegade in the swamp (i don't know why, but i start the game with an AK in my inventory).

this is what i have so far, had no crashes with this appart from when i tried to use a medkit:
things i've changed are in bold and red

i really want to make this gun fun, so i can use it from start to finish.
this means i need to change the ammo power this gun uses: i would like shot to be more precise (less dispersion on longer distance) slug to be able to pretty much instakill unarmored NPCs, and dart to be used to pierce almost any armor.
also, i want to have fun seeing them fly through the air so the ragdoll effect should be quite high (without exagerating as i don't want them to die because of the flight...)
when i tried to change the ammo numbers in the weapons.tlx, i got CTD, same with the changes i made to the weapon, but this only when i use a medkit, go figure..., no biggy i just use a trainer so i can't die...
but if you could help me buy telling me what parameters have to be changed for this to work and be kind of reallistic, please let me know.

i would also appreciate if someone could write a guide explaining how to mod, i learned by checking this post:

http://forums.filefront.com/s-t-l-k-e-r-soc-modding-mapping-editing/307191-basic-modding-playable-examples.html

but i feel like it is not the best place to learn modding for total noobs like me.
tnx

Welcome to the forum, mimic.

On the AK-74 issue, changing to a seemingly more powerful ammo does not necessarily help increasing the weapon's hitting power to an extent you wished. Instead of making the AK-74 fire shotgun shells, you can keep its original ammo or an ammo to still near to its own ammo size, but you can increase the hit_power and hit_impulse. You can check the values of more powerful similar weapons in the game and start from there.

On the modding guides question, the site that you refer seem quite adequate enough for giving a range of information on modding works. While it is relatively easier to change some values on item by item basis,( even which, I must emphasize that could produce some hazardous results if the game is checking "those values" in order to proceed with other functions) however, a larger scale modding would inevitably require a certain degree of understanding of scripting; how to read it to understand what a particular piece actually does and how that piece also affect the whole in general, so that the things would not contradict in the sense of computer working logic and so that the game would not crash.
It's learning process and can be achievable. There are a wealth of information on this site as well, you can start reading, it's a long walk; also there are many links on this site as well which refers some others sites giving additional and in some cases more detail information on various subjects in this work.

Thanks for the quick reply, as the game is a few years old and got worse reviews then SoC, I feared it might be a while.

On another topic, can you please explain me (this is just for my personal fun...) how to create a completely new weapon from an existing one, without removing the game gun. I tried to create a .50 cal sniper rifle (Barrett m107) based on the SVD rifle and the 7.62 7h14 ammo (both just for visuals as i don't know how to create all the graphics and such associated with creating from scratch) without removing the SVD and the 7.62mm ammo. i just want to have fun and have a gun specifically for shooting bad guys hiding behind cars (so hit power on the gun and AP on the ammo will be quite high), is there a limit to the nuber you can put in those fields, i tried 10 and it didn't work, when the base was around 1.5. so i did a copy-paste of both in their respective file and changed the name, description, and values, all the rest remained unchanged..., however when i try to launch the game, it either CTD on startup, or when i load the game, on the "client synchronizing" phase. Can this be done, or can a specific weapon (graphic, animation, sounds...) be only used once?

You're welcome

Making a new gun from scratch with its graphics and animation, such as adding a Barret.50 cal with its own visuals, for example, is not an undertaking that can be seen lightly by any standards. It involves the knowledge and ability of working with professional graphics software, just for the visuals. On this forum, our talented friend jamie1992 has a graphics thread in which he renders some cars and other stuff which shows the level of graphics knowledge required for such tasks.
Show off your 3D models:
viewtopic.php?f=26&t=176

Apart from that, apart from (graphically) creating and incorporating a new gun into the game, an existing weapon can be changed in values as if it is a new weapon while keeping its visuals as the original one, but in a way having visually two copies of the same weapon, while each behaves differently. But this involves a bit more work than just adjusting the power values of the weapon, of course.

Long articles exist on this matter.

Check threats on this section of this forum, and also check the links on this section again on Important Links to Modding Questions and Answers, here:
viewtopic.php?f=3&t=145&p=2379#p2379

And, some example links from that thread:

Basic Modding with Playable Examples
http://forums.filefront.com/s-t-l-k-e-r ... mples.html

Also, another link from there to MOD SDK Official Help site: (you can navigate in the site to the subject you are interested in)
http://sdk.stalker-game.com/en/index.ph ... icial_help

I believe those articles that you would find in these places/threads would answer and direct your questions. Good luck.

Hi mimic,

Just by reading your post I`m assuming youre getting a "duplicate section" crash.

What you need to do is :

1) create a new section name and inherit from the old one like so :

[wpn_barret]:wpn_svd
--here change all that you want to change IE ammo and the like

2) add your new section to mp_ranks so that npc`s can evaluate the weapon when picking it up.

3) add your weapon to the trader files so that it can be bought

4) add a new icon to ui_icon_equipment.dds so that your new weapon will look unique in your inventory
This will not mean, however, that it will look different ingame, this will require making a new model and meshes.

Then it should work fine
