+====== Ballistica Mechanic ======
+**Ballistica** is the line-of-sight and ranged attack calculation system used in Remixed Dungeon for determining if ranged attacks, spells, and other line-based interactions can reach their targets.
+==== Overview ====
+Ballistica is the fundamental system that calculates straight-line paths between two points in the dungeon grid, accounting for walls and other blocking terrain features.
+==== Mechanics ====
+  * **Line Calculation**: Determines a direct path between source and target positions
+  * **Obstacle Detection**: Identifies which cells in the path are passable or blocked
+  * **Target Validation**: Ensures that ranged attacks and spells can reach their intended targets
+  * **Distance Calculation**: Used for range limits of various abilities
+==== Applications ====
+  * **Ranged Attacks**: Validates if thrown weapons can reach targets
+  * **Spell Targeting**: Determines if spells can reach their targets
+  * **Sight Detection**: Used by enemies to detect the hero when unobstructed
+  * **Special Abilities**: Powers abilities that work in straight lines
+==== Technical Details ====
+  * Implementation: [[https://github.com/NYRDS/remixed-dungeon/blob/master/RemixedDungeon/src/main/java/com/watabou/pixeldungeon/mechanics/Ballistica.java|Ballistica.java]]
+  * Class: Core mechanics class for line calculations
+  * Algorithm: Calculates the path using line-of-sight algorithms that consider dungeon geometry
+==== Usage in Tengu Combat ====
+  * **Ranged Attacks**: Tengu uses Ballistica to determine if it can attack the hero from a distance
+  * **Combat Strategy**: Uses line-of-sight checks to position itself strategically
+  * **Distance Management**: Evaluates line-of-sight to know if it needs to use teleportation

+==== JSON Configuration ====
+  * Configurations for ranged combat mechanics and LOS calculations can be found in various JSON files in ''RemixedDungeon/src/main/assets/''
+==== String Resources ====
+  * Ballistica-related strings are generally defined in connection with ranged combat and spell systems
