Official Workshop description

MILSIM CREATOR FRAMEWORK - STEALTH MODULE EARLY VERSION - the rules run and have been checked on a server without players. Nobody has sneaked past a real patrol with it yet. In vanilla an AI soldier that sees you a little is on you. Here it has to make up its mind. You give off two numbers, what the eye gets and what the ear gets (0 to 100). Every AI near you keeps its own awareness of you and vanilla's combat only gets you when it reaches 100. WHAT YOU GET - Two bars for the player, worked out on the server twice a second: the eye (vanilla's own visibility, which already counts stance and light, times how fast you move) and the ear (movement, stance and the ground you walk on). Sprinting in a vehicle counts as running. - Awareness per AI per player. It rises while the AI sees you and when it hears you inside a range that depends on your noise; it falls when it loses you. A bullet past an AI or a hit is 100. A shot heard raises the whole group to "investigate". - Bands: nothing, "hm?", investigating, alert, then combat. Between "hm?" and alert the group is told there is something and goes to look; at 100 it fights. - It only concerns a player's character. AI against AI stays vanilla. - Two small bars on the player's screen, an eye and an ear, bottom left. A third piece, an eye in the middle of the screen that fills when someone notices you, is available and OFF by default (setting noticeEye). Only the band is sent to the client, never the number. - Other modules can change your bars through Core's modifiers (stealth.visual and stealth.audio), for example a perk. Stealth does not name any other MCF module. ZOMBIES AND OTHER AI MODS Some mods (Bacon Zombies is the one this was written for) run their own behaviour and never ask vanilla who to shoot. Stealth finds such a man by behaviour, not by name: one that has not used vanilla's target pick for ten seconds. Nothing is gated for him; instead his perception factor is set from the nearest player's bars and distance, and put back when nobody is near. It is coarser than the bands above. If your zombie mod sets that factor itself, Stealth overwrites it while a player is in range. FOR SERVER OWNERS - One settings file, written with defaults on first start: $profile:MCF/stealth/settings.json. Switches: enabled, gate, fallback, hudBars, noticeEye. Then reach (radius, tick), the bar values, the awareness rates, the fallback numbers and the HUD place. A value out of range is corrected for the run and logged. - Log lines start with [MCF-ST]. - Switch gate off, or enabled off, and vanilla behaviour is back after a restart. MEASURED, AND NOT - Checked on a dedicated server with no players: the bar maths, the awareness rise and fall, the three places where vanilla's target pick is gated, the fallback for an AI with its own brain (with a switched-off vanilla man), and the cost of a tick. - The rate at which an AI gains awareness at 150 m was measured on the probe. - NOT tested with players: the bars drawn on screen and whether they overlap the stance or stamina icons (move them with hudLeft and hudBottom), a walking player's movement classes, the surface factor, a real player as a target, a group of three or more, a vehicle, 30 players with 150 AI (the cost), and Bacon Zombies itself, which was not loaded on the probe. - The numbers are first guesses. Feel these first: visStill (a man standing still shows 55 to the eye), audioRange (40 m at a noise of 100), radius (also the longest distance a fight can start from) and decay. KNOWN LIMITS - The numbers are not tuned. - The fallback for zombie mods is coarse: perception is scaled, not gated. - Needs a connected player to see anything. In a mission with no players it does nothing. DEPENDENCIES - Milsim Creator Framework - Core (Works beside MCF Character: a stealth perk can plug in through Core, nothing is needed.)
