- 2010 © Alexey "KamikaZze", reconstruction of behavior scheme "Companions"
- Please send feedback via e-mail: kamikazze-ru@yandex.ru

- Many thanks to kolinkoff YouTube user for supplying me
- the english version of original game and for the testing -
- this made my release possible. Thanks again to kolinkoff!
-------------------------------------------------------------------

Anticipating some questions I have to say the following:

This is not a clone of "Partners" mod and not its conversion; this scheme has been written almost from scratch, but in this scheme I used one of "Partners" algorithms (jumping of NPC between locations) by Dmitry Roshchin aka Red75 and for that my acknowledgements to him. The idea proved to be convenient and very viable. In fact I've just adjusted the implementation of his method so that its use does not interfere with the normal operation of conventional NPCs in smart terrains. This scheme is based on a small scheme xr_companion from original and the builds by Sergei Vinnichenko. This scheme worked in a build 2205 but in release it was disabled. As useless apparently - it haven't been finished.

So that's the companions. This behavior scheme allows you to invite NPC as a companion and together explore the Zone. Idea of reconstructing this scheme was born when I saw it initially in build 2205 and decided to revive for our global mod - OGSE (Old Good Stalker Evolution). In this case I tried to give scheme maximum flexibility and functionality as much as been possible, while also tried to avoid potential problems - so that the player didn't required to nurse his mate, pulling him out of any trouble.

WARNING! During the operation of the scheme it had been discovered that some (fairly rare) NPCs behave strangely when hiring - do not go after the Player, staring dully into space, do not pass through the levels. It is a conflict between the behavior scheme and built-in logic, it happens mostly with guards of scripting camps. If you hired such NPC - leave it alone and hire another.

Also in this package included custom gamegraph of original game corrected by me especially for this behavior scheme. The length of all transitions between locations had been reduced to a minimum and eventually your partner overcomes transitions between locations almost immediately - within 10-20 game minutes (1-2 real time minutes).

USE CUSTOM GAMEGRAPH ONLY WITH MODS WITHOUT NEW LOCATIONS!

So in OGSE, OGSM and AMK too, if I remember correctly, you can use custom gamegraph completely painless, as they wasn't changed it. If, however, you install it on the mod which already contains edited gamegraph (ANY mod with new locations) game will behave unpredictably, or new locations became unreachable, so don't even try.

The main features of the scheme:

1. Mate follows you wisely - no chasing stray dogs and wild boars, no trying to chase them through the entire location, so don't panic.
2. If you decide to escape combat - a partner will escape with you, not reacting to the enemy. This allows us to get out of the fire without the risk of once again taking the fight against superior enemy forces.
3. With a partner you can direct exchange goods for no price - via trade menu. Exchange is free which is convenient.
4. All settings are stored in a special scheme repository inside the companion's packet - for this I used utility functions from a library of utilities for working with net packets - m_net_utils (SIMBION: SHOC mod), author Artos. The library is included.
5. Mate can disguise armor when used in conjunction with the scheme xrs_armor, author xStream. Modified for this purpose scheme xrs_armor attached. Notice that it's not acivated just from box and needs to be edited before use.
6. To use mods in which player can join the factions the scheme supports the following factions companions: a loner, duty, freedom, gangster, zombie (the latter experimental, working but not very good). Moreover, each faction in the scheme have their own style of dialogs. For the integration scheme in such mods you should check IDs of factions in function community_by_actor (actor_comm) and, if needed, rewrite. Companions can be hired only from the faction to which player now belongs. In addition to the binder of scheme immediately entered evaluators of behavior schemes xrs_grenade, xrs_medic, rx_bandage, rx_facer, rx_reload, and anomaly_evader, so that it can be used together with xr_companions with minimal adjustments together with anomalies evade packs of logic and the arms manager (from AI Pack).
7. Following restrictions apply to the hiring of teammates:

1) You cannot hire quest NPCs (for obvious reasons)
2) Player has bad reputation in faction
3) This is some of the prisoners
4) Player experience is lower than NPC
5) Player much more experienced than NPC (beginners are afraid to go with the experienced stalkers, fearing that they use them as a "jemmy"
6) The Player already have a partner (with a little edits this scheme could support more than one partner, but for me it was not appropriate as heavily disbalancing the game, so I did not do it - and please don't ask - if you are skilled enough you can add this yourself)
7) Player from other faction (can be turned off if necessary: edit in the header of xr_companions.script parameter other_factions_switch)
8) Too many companions were died with Player

8. Yes, the scheme is counting and recording "death toll". If you had lost in action more than 4 NPCs they will refuse to go with you. To correct the situation you may treat wounded stalkers. For each saved life you will write off one victim.
9. The scheme has the following behavior types:

1) Follow me
2) Wait here
3) Sneak after me
4) Hide here

Moreover, for each of these scheme has three modes of aggression:

1) Normal
2) Reduced aggression (allows companion to come closer to the enemy)
3) Low (companion hides his weapons and not engages in battle until he or Player obtains some damage)

This set of functions allows the use of team-mate in the cases when it is necessary to make ambush or covertly change position. In addition, it can hide in safety so that it didn't attract enemy attention.
10. Especially for a partner I've prescribed additional state types on the basis of a panic run that he didn't get lost from Player when Player runs in haste.
11. You can use the radio to instruct your mate what to do. Radio works within a radius of a-life (about 150 meters). Also be aware if you left your partner behind and go beyond a-life radius (about 150 meters) he will most likely go to the camp.


Future development plans:

1. Add a weapons selector so you can instruct companion what type of guns to use (long range, close combat, etc).
2. Make a "follow-me-step-in-step" mode.

Now the companion can be used in attacks on the enemy base - behaves well, does not rise noise to the last moment, and due to its low visibility you can sneak very close to the enemy. In addition modes "Hide here" and "Hide here and don't attack enemies first" help to set up ambush for the enemy.

The scheme was finally made fully functional and suitable for permanent use. In the "no enemy attacks first" NPC are hiding weapons and behaves extremely quiet until it does not suffer damage, or it won't get hit. Then starts to fight. Nevertheless, these modes should be used with caution as such NPC as at the post of Kuznetsov still attacks NPC, even if he isn't taking hostile action. Should bear this in mind.

* Corrected inability to speak with a companion after loading saves

Version 0.3
-------------------------
+ exchange of goods between the actor and his companion is now possible free of charge

Version 0.2
-------------------------
+ saving of the scheme is implemented as follows: NPC is appointed to actor faction. After game loads the NPC switches on scheme automatically if its faction will coincide with the actor.
+ NPC becomes a friend to actor after hiring
+ NPC switches to a neutral to actor after retiring
+ NPC returnes to his original faction based on its visual after retiring

Gamegraph editing and adaptation of scheme to mods with new locations:

I'm worked with the graph using a script gg_cdc_x4 by Xiani: http://www.sendspace.com/file/xat026
It's simply to use (only thing you need to run is installed ActivePerl) - who was unpacking at least once allspawn by ACDC, will understand how use it without any problems. Method is the same. You decompressing gamegraph, and get a huge pile of configs from it... find there a reference configuration file game.graph.info.cross_edges.ltx - it lists all the points of the transitions between location that were found when unpacking a gamegraph. All these points must be found in the main configs of locations - they named as game.graph.edges.<location_id>.ltx, search by parameter "edge_offset". Once found, you need to change "distance" parameter of what vertexes link (the distance between the vertexes in conventional gaming meters) to any small number. I personally put 5. Further, after treating all the transitions in this way, you have to recompress gamegraph back from configs and use it. Now transition times between location are greatly decreased to everyone - both you companion and other NPCs and monsters to, what lead sometimes to very interesting situations, greatly adding fun to gameplay. For example in our OGSE mod after that correction in gamegraph we somtimes get an attacks of Monolith fanatics in DarkValley, DarkValley bandits on Escape (quite a coomon thing now), Yantar zombies attacks on Agroprom and once time user even encounters a pseudogiant on Escape! This is because game is sending NPCs and monsters to other gulags then they current one is overpopulated. Original transitions between locations are very long - ranging from hundreds of meters to some kilometers, and then distances are cut to some meters then sometime nearest empty gulag is on other location nearby, so game sends NPCs and monsters there. This side-effect howewer wasn't ruining game balance but make it more fun. It's now real Zone there you never can say what awaits you.

So, adapt the companions scheme for new locations is easy enough. Most important thing - new location must be already registered in gamegraph, and must have registered level-crossings in it (actor level-jumpers unsuitable for the NPCs, they can move between locations only using vertex links in gamegraph). If all this has been done, and the NPC could freely visit the location, you need now only add records in the table named "offline_dest_table" in the main script of companions - "xr_companion.script" - table is almost at the end of the module. Table contains records with smart_terrains IDs, in which companion can be sent by game to move between locations. Entries looks like follows:

l07_military = {
none = "mil_dolg_ambush_walk1"
}

Ie this table records also is the small tables, which have as key an identification names of locations, and contains inside the names of smart_terrains, as they are defined in allspawn, usually one per location. Suppose we have location Generators named "l13_generators" and smart_terrain called "gen_last_hope_smart4". Then the record will look like this:

l13_generators = {
none = "gen_last_hope_smart4"
}


smart_terrain must be such type as to accept any faction NPCs. How to spawn it - your choice, the easiest way is to add it directly to allspawn of location. You can use the camp (camp fire) smart_terrain, albeit undesirable - because teammate, trvelled there in offline mode, may be in the vicinity of the already occupied smart_terrain before him bandits for example. And when you go there to reunite with him, he goes online at the same time with them and be killed. So now the scheme commonly using disposable scenario smart_terrains.

That's actually a checklist of what should be done for ensure companion (or indeed any other NPC) could visit the location:

1. It must have properly working AI-net.
2. Vertex grid of location must be correctly registered in gamegraph.
3. The pair of location vertexes in gamegraph must have link to vertexes of other location - they work as transition ways to NPCs.
4. On location must be at least one smart_terrain what able to take any NPC.
5. In xr_companion.script a table "offline_dest_table" must have record of this location with the name of what smart_terrain.

In fact, all items except 5th, do not apply directly to the companions. What is described in sections 1 to 4 should be done initially by mappers when connecting new location to the game, otherwise it is a waste of time, because locations not connected to others would not be able to use by the NPC. But if it's already been done, then you will need only complete 5th action to go.

One small addition to manual - note what location IDs and smart_terrrains names in table "offline_dest_table" ARE CASE-SENSITIVE! If you write at least on charaster of them in wrong case it's wasn't work, so be careful. And one more - you don't need to add a new smart if you already have some camps on location - just find a suitable and use it. And one more thing i forget to mention - if you wasn't changed anything except transition distances in gamegrath you don't need a start new game - changes take action immediately.
