Skill-based Trap Detection
Version 0.9.3
By AdituV
Source code is both included in the mod and available at
<https://github.com/adituv/morrowind-trap-detect/>.
With thanks to Graphic Herbalism, the lua source of which I used as reference while developing this.
Skill-based Trap Detection is a pure-lua mod to allow the player to have a chance to successfully detect a trap based on their security skill and relevant attributes, with a formula similar to the vanilla game.
This beta version has all core functionality implemented, but is lacking features for magic-using characters.

Requirements
Installation
Install as normal with a mod manager of your choice, or extract the files directly to Data Files. The usual.

Details
On looking at an object that can be locked (currently defined as a door or a container that is not organic), your "effective skill level" is calculated, smoothed, and compared to a randomly generated number. The result of this is cached until you change cells or until your Security skill increases - this includes temporary bonuses.
Your "effective skill level" is calculated with this formula:
Where
The effective level is smoothed along a sigmoid curve; the default parameters give the following equation:
You can modify these parameters in the MCM. 0.05 is the "steepness" term divided by 100; 70 is the "midpoint" term.
The random number generated is uniform between 0 and 1, and if that number is less than the smoothed effective level, the detection is considered a success. Depending on whether the object in question is trapped or not, either "Untrapped" or "Trapped" will be added to the tooltip. If detection fails, "???" will be added to the tooltip.
The graph below shows the chance of detecting a trap at different effective security levels and fatigue:

Details

The result of this is cached until you change cells or until your Security skill increases - this includes temporary bonuses.
Your "effective skill level" is calculated with this formula:
effective level = fatigueMod * (security + (agility / 5) + (luck / 10))Where
fatigueMod = fFatigueMult * normalizedFatigue + fFatigueBaseThe effective level is smoothed along a sigmoid curve; the default parameters give the following equation:
f(level) = 1 / (1 + e^(-0.05 * (level - 70))You can modify these parameters in the MCM. 0.05 is the "steepness" term divided by 100; 70 is the "midpoint" term.
The random number generated is uniform between 0 and 1, and if that number is less than the smoothed effective level, the detection is considered a success. Depending on whether the object in question is trapped or not, either "Untrapped" or "Trapped" will be added to the tooltip. If detection fails, "???" will be added to the tooltip.

Planned Features
- Features for magic users:
- Spell to boost detection chance
- Spell like Open but to remove a trap
- Spell to add a visual effect to trapped things (maybe)
- Similar functionality for locked state
