NT-3 Tweaks #5138

SirWarock · 2026-01-05T13:29:45Z

About the PR

I adjusted the values of the NT-3 to be weaker in an traitors/nukies hand.
The NT-3 cannot be parcel wrapped anymore.
The NT-3 will prevent the user from going invisible via stealth.
Firerate decreased: 4 shots per second -> 3 shots per second. Firerate with bipod remains unchanged at 7 shots per second.
Ammo capacity increased: 60 -> 80.
Bipod-Deploytime decreased: 2s -> 1.25s
Movementspeedslowdown increased: 10% -> 20%
.40 Anti-materiel ammo box (the printable one): 30 bullets per box -> 40 bullets per box.
Added CombatModeComponent to the whitelist, causing it to not infinitely pierce most living entities.

Since these adjustments negatively affect our beloved local cargo antag the most, I've taken the liberty to name the PR accordingly.

I also adjusted the wielded sprites, they looked off.

Why / Balance

Parcelwrapping the NT-3 to turn it from a Backpackslot only weapon into a 2x4, circumventing the movementspeed debuff, is outright crazy. I specifically only allowed backpackslot to make the NT-3 unwieldy and a commitment - You cannot carry a secondary weapon to defend yourself, unless it's a pistol. Parcel wrapping went against this philosophy.
Stealth with the NT-3 is also outright bonkers. I do not need to explain why.
I decreased the firerate because I read that 4 seccies with 4 NT-3s decided to run down a dragon and a colossus with it.
You should never willingly use the NT-3 without the bipod - That should be a last option, a desperate attempt to keep an enemy from advancing. If you don't wanna use the bipod, use a lecter.
Increased the slowdown to make it more likely to be caught out with the weapon. Better have teammates that can back you up.
Bipod-Deploytime has been decreased due to the firerate and slowdown nerf. while you have a harder time getting into a good position, you'll have an easier time capitalizing on one.
Ammo count has been increased because I wanted to.

Technical details

Bunch of YML changes.
Added the PreventStealthComponent and added checks for it in SharedStealthSystem.
Added AddedStealthEvent and StealthModifiedEvent to work with the afforementioned component.

Media

NT-3.Adjustment.mp4

Requirements

I have tested all added content and changes.
I have added media to this PR or it does not require an ingame showcase.

is it possible to limit the penetration range (like the bullet can only go through 3 things at max, like walls and humans) or is it coding hell

SirWarock · 2026-01-05T13:50:51Z

is it possible to limit the penetration range (like the bullet can only go through 3 things at max, like walls and humans) or is it coding hell

Currently, it goes through 1 whitelisted entity and an infinite amount of non-whitelisted entities.
Current whitelisted entities are walls. If it hits one wall, it'll pierce that wall (unless it has a high enough health like reinforced walls) and then be stopped by the next.
Humans are currently not whitelisted. If I were to whitelist them, they'd count as a wall. That is all possible via YML.
However.
If I am to differentiate between humans and walls (aka between whitelisted entities), that would be coding hell.

ShepardToTheStars · 2026-01-05T14:25:01Z

Currently, it goes through 1 whitelisted entity and an infinite amount of non-whitelisted entities.

I'd really rather not maintain an arbitrary whitelist of things the NT-3 suddenly cannot penetrate well.

What if you kept track of how many entities it has pierced, and just put in a way for there to be a MaxPierces and despawn the bullet once it meets or exceeds that amount?

That is possible, but then I couldn't differentiate between a mouse and a wall. With how I coded it currently, it allows for a much finer control as to what should count towards the penetration counter and what shouldn't.

Well, you could turn the blocklist into an actual EntityBlacklist, make PierceCounter count every entity it hits, then just do something like.

(psuedocode)

if (comp.PierceCounter >= comp.MaxPierces || _whitelist.IsBlacklistFail(comp.Blacklist))
  DeleteProjectile()

SirWarock · 2026-01-06T02:24:20Z

I turned it into a whitelist now - which is much more of an elegant solution than the List<<ProtoId>Tag> was.
I added CombatModeComponent to the whitelist, so anything that can fight will count towards the counter.
It can only pierce 1 human and hit the second, for example.

        // If it does have the tag to stop it and enough health to count as "strongly armored", it'll block the bullet.
-        if (bullet.Comp.HealthThreshold < args.RequiredDamage)
+        // Mobs return a required Damage amount of Float.MaxValue. Therefore we need to check for absurdly high values.
+        if (bullet.Comp.HealthThreshold < args.RequiredDamage && args.RequiredDamage < 20000000)


Magic number. Declare as a constant and give it a descriptive name. Also, probably comment how you derived it (if it was more than picking 'BIG NUMBER YAY!')

Suggested change

if (bullet.Comp.HealthThreshold < args.RequiredDamage && args.RequiredDamage < 20000000)

if (bullet.Comp.HealthThreshold < args.RequiredDamage && args.RequiredDamage < 20000000)

+    setupDelay: 1.25


Direction requested change. We like the bipod time at 2 seconds because it allows people to get to cover if they realize there's an NT-3. If we lower it, we run into the territory that even if you notice it and start running for cover, you're still going to get shot.
