• Weapons and armour now have an internal repair threshold. When an item gets damaged (and thus its status is lowered), there is a (xml-based) chance that its internal repair threshold is lowered as well.
• A gun can only be repaired up to its internal repair threshold by your mercs, not above that (not even by engineers). The only way to restore it up to a 100% is by having on of Arulco's smiths repair it in their shops.
• The goal of this feature is force the player to be more careful with his equipment. Either have spare weapons, maintain fire discipline (thus damage your equipment less), or make use of the local smiths (which were to much underused imho).
• As the chance to damaging the internal repair threshold is xml-based, weapons can differ here up to your own wishes. With my stock values, AK-based rifles have a lower chance to internal damage, representing their durability. Thus these guns are easier to maintain, especially if you have no access to spare equipment or the smiths.

• Every gun now has a 'dirt value'. Firing a shot adds dirt to the gun's dirt level. This can get modified by attachments and the ammunition type.
• The sector you are in has a very high influence on the amount of dirt added. It is not much in cities, but swamps and especially deserts add a lot of dirt.
• Your weapon will also slowly get dirtier just by being in a sector or your inventory. Note that by keeping a gun in a holster or bags, you will reduce the amount of additional dirt they get.
• The higher a gun's dirt level is, the higher the chance that it will jam.
• The dirt value is also xml-based. Some weapons, like the M16A1, a very vulnerable to dirt, a clean M16 will have severe problems after jsut 2 magazines in the desert. Others, like the SCAR, can fire a lot more until they jam.
• There are two ways to clean a gun:
  
  • if you repair a gun up to 100% (or its current internal repair threshold), it will also get cleaned.
  • use a cleaning kit (new item #1576). Just have one in your inventory and press 'Ctrl' + '.' and click on the 2nd button. All your guns will get cleaned (if they are dirty to begin with). If you are currently in combat, this will cost APs (ini-value), and only one gun will get repaired, starting with your hand slots.
  • cleaning kits can degrade by use, but it'll take a long time to use up one.

• is an UINT8 value. It describes the chance that upon lowering the item's status, the internal repair threshold will be lowered as well.
• is a FLOAT value. It is the base value of dirt generated with every shot, as well as the base for time-based dirt generation.

is a FLOAT value. It describes the additional dirt generation if using this type of ammunition.

Map/SectorNames.xml:

is an UINT16 value. It describes how many percent of dirt will be generated. For example, deserts have a value of 1000, which means that in a desert you will generate 10 times as much dirt as in a clean city.

And now a few demo pics:


Spam's M16 is already very dirty. It jams, even though its status is very high and its temperature is 0.


Dirt modifier description. The gun's value of 60 is increased by 20% due to using AP ammo (ammo types add/substract a percentage of dirt). Note the status bar on the left side indicates that the internal repair threshold is lower than 100%.


Ammo dirt modifier.


This flak jacked is highly damaged, and thus, it can onyl be repaird up to 77%

I will add this to the trunk if nobody is against that, but now, discuss this, and please give feedback/critique/suggestions.

This is now in the trunk r5480, necessary GameDir is 1498.

Your weapon will also slowly get dirtier just by being in a sector or your inventory.

• 2: in turnbased, the currently selected merc will clean the first gun in his inventory he finds if he has enough APs
• 2: if not in turnbased, all mercs in this sector will clean the first gun in their inventory
• 3: in turnbased, the currently selected merc will clean all his guns
• 3: if not in turnbased, all mercs in this sector will clean all their guns

Ah, now I see. Due to an oversight, one couldn't repair anything other than guns and armour. This has now been corrected in r5692 - you can repair grenades and other stuff just like you used to.

Figured not being able to repair everything was a new feature.

Further features are planned, but I won't tell... more surprise that way

2. Just for illustration. I have no idea on how specific ammo types cause dirt. All xml values are just my uneducated guesswork. My hope is that people that do know start filling these values.

While I personally won't use that option (I always use a dedicated repair team that mostly consists of technicians/engineers, which would render this feature pointless with the option), this seems to be a much-demanded point... Committed in in r5917 and GameDir r1619. Thank you, merc05

Hm... maybe I'm doing something wrong, but the feature is not working for me... I'm using Jagged Alliance 2 v1.13 r5927 & r1622 data, AFS 4.30, and have the option set to TRUE in ini, but when I set Maddog (Engineer, new trait system) to do repairs, with just the broken pistol (3%) in whole squad inventory, it can't go beyond 3% anyway. it keeps saying "Maddog lacks the necessary skill to repair anything" and stops the time compression. here's my ini: http://pastebin.com/yJfbQZ6S

EDIT: A thought, maybe it works with technicians only, and not ENGINEERS?
EDIT2: Just hired Barry and checked this; it does not work with him as well.

EDIT3: It's also worth mentioning an oddity - since I was fiddling with ini anyway, I tried to disable the advanced repair system altogether, fix the gun, save the game and enable it to see what happens - everything works fine, to my surprise . Just one oddity - the repaired gun is now at 40% but after re-enablind advanced repair system, it's threshold is still at 3% . I guess theren't nothing to do about it though, since it works as intended.
