Jagged Alliance 2 Data Dictionary

A comprehensive glossary defining the strict file typings, arrays, and variables used to natively compile assets into the Jagged Alliance 2 1.13 executable.

File Typings

Extension	Format	Definition & Constraints
`.STI`	Sir-Tech Image	Proprietary ETRLE compressed format utilizing strict 8-bit, 255-color indexed P-mode headers. Used explicitly for BigFace rendering arrays, Tactical HUD sub-frames, and item geometry. All layers in an STI must use the identical color palette.
`.EDT`	Encrypted Data Text	Binary blob files housing string primitives (e.g., `AIMBIOS.EDT`). Values are obfuscated with a hard-mathematical `ord(char) + 1` ASCII shift compression scheme. Padded strictly with null bytes up to exact index boundaries.
`.XML`	Extensible Markup	Exposed hardcoded executable constraints from standard 1.12 builds ported over in 1.13. Provides arrays replacing original executable behaviors. File naming and node schemas are strictly enforced.

Core Index Metrics

Variable	Type	Application & Engine Rules
`uiIndex`	Integer	The absolute variable identifying a character/asset globally. A mercenary at uiIndex 28 loads `28.sti` and begins their EDT memory offset at byte `31360` (28 * 1120).
`bLife`	Integer	Maximum Hit Points. Values over 100 may invoke integer overflow logic.
`bAgility`	Integer	Governs Action Point (AP) density and combat maneuverability.
`bDexterity`	Integer	Controls fine motor accuracy: lockpicking rate, trap defusal speed, and raw repair efficiency.
`bWisdom`	Integer	The experience multiplier. The higher the wisdom, the faster the mercenary organically levels up.
`bAttitude`	Integer ID	Determines dialogue audio behavior. 1=Friendly, 2=Loner, 3=Optimist, etc.
`usEyesX / Y`	Vector2 (Px)	Physical absolute X/Y overlap coordinates where the engine pastes the 17x6 blinking ETRLE strip over the static 48x43 Base Render.
`usMouthX / Y`	Vector2 (Px)	Physical absolute X/Y overlap coordinates where the engine pastes the 14x6 talking ETRLE strip over the base render.
