📋 About This Mod

Tired of the bolt-unscrewing routine? Random events for stuck bolts — WD-40 can fail, threads can strip, forcing a bolt risks breaking the part, and latent rust can hide in a healthy-looking one. Fully configurable — no restart needed.

Description

Tired of the bolt-unscrewing routine in Car Mechanic Simulator 2021? Bolt Events turns it into a small gamble: random events fire no matter how you deal with a stuck bolt, and latent rust can hide in a bolt that looks perfectly healthy — so it never feels scripted.

How it works

WD-40 path (rolled right after the sprayed bolt actually loosens):

  • []"WD-40 didn't help" (default 15%) — the bolt seizes back; you have to spray it again.[/]

    []"Stripped threads" (default 4%) — the bolt is flagged: when it later comes off, the part it held loses 5% of its CURRENT condition (100% → -5, 20% → -1), and you pay 50 CR for your nerves. +5 XP for the experience.[/]

    Ratchet path (left-click on a stuck bolt without WD-40):

    • []"The bolt gave way!" (default 15%) — pure force and stubbornness loosen the bolt without WD-40.[/]

      []"Stripped threads" (default 7%) — same damage event as above. Forcing a stuck bolt is always a risk of breaking the part.[/]

      Latent rust (new in 1. 6 — rolled when you enter an unmount session, e.g. wheel / hub):

      • []"The bolt seized!" (default 10%) — one random healthy-looking bolt of the mount is secretly rusty. No visual difference: same yellow outline, same green hover — until your first click, when it seizes right on the spot. Deal with it like any stuck bolt (ratchet clicks / WD-40), and all the events above apply. If you leave the session via ESC without touching the bolt, the rust vanishes and the pick is re-rolled next time — nothing is ruined behind your back.[/]

        The stripped-threads damage numbers (condition loss, money penalty, XP reward) and all event chances are configurable.

        Installation

        • []Install MelonLoader for CMS2021 if you haven't yet (standard installer, pick the game folder).[/]

          []Copy BoltEvents.dll into "Car Mechanic Simulator 2021\Mods".[/]

          []Start the game. Done — the config file is created automatically on first launch.[/]

          Configuration

          The mod has its own config file:

          Car Mechanic Simulator 2021\Mods\BoltEvents\BoltEvents.cfg

          It is created automatically on first launch with all defaults and comments. INI-style "key = value" lines, UTF-8, "#" or ";" start a comment. Available keys:

          Enabled = true                    master switch for all events

          ChanceWd40FailedPercent           "WD-40 didn't help" chance (default 15)

          ChanceStrippedThreadsPercent      stripped threads via WD-40 (default 4)

          ChanceUnscrewNoWd40Percent        "bolt gave way" chance (default 15)

          ChanceSlipStrippedPercent         stripped threads via ratchet (default 7)

          ChanceSeizeNormalBoltPercent      latent rust on a healthy bolt (default 10)

          StrippedConditionLossPercent      condition loss on stripped threads, percent

          of the part's CURRENT condition (default 5)

          StrippedMoneyPenalty              money penalty in CR, charged only if you can

          afford it (default 50)

          StrippedExpReward                 experience reward (default 5)

          DebugLog = false                  verbose logging (troubleshooting only)

          All popup phrases are user-configurable too, in both languages (the in-game language decides which one is shown): TitleRU / TitleEN — popup title; Wd40FailedRU / Wd40FailedEN — "WD-40 didn't help"; BoltGaveWayRU / BoltGaveWayEN — "The bolt gave way"; StrippedRU / StrippedEN — "Stripped threads"; BoltSeizedRU / BoltSeizedEN — "The bolt seized" (latent). Use {0} in the stripped-threads texts where the condition loss number should appear.

          The file is re-read before every event roll — edit it any time, even while the game is running; no restart needed.

          Main features

          • []Random "seize back" outcome after using WD-40 — no more guaranteed one-spray bolts.[/]

            []Force-only unscrewing without WD-40 can also succeed (ratchet slip events).[/]

            []Stripped-threads events damage the part the bolt held (5% of current condition) and cost CR, with +5 XP.[/]

            []Latent rust (1. 6): a healthy-looking bolt can secretly be rusty and seize on your first click — check your bolts, or pay for skipping WD-40.[/]

            []Every chance is configurable in a dedicated config with a documented default.[/]

            []All popup texts are fully customizable in Russian and English — write your own flavor.[/]

            []Debug logging toggle for troubleshooting.[/]

            []Lightweight: a few Harmony patches, no per-frame overhead.[/]

            Requirements

            MelonLoader 0. 5.x or 0. 6.x (tested on 0.
