#include "script_component.hpp"
/*
 * Author: PabstMirror
 * Manually Apply Damage to a unit (can cause lethal damage)
 * NOTE: because of caching, this will not have instant effects (~3 frame delay)
 *
 * Arguments:
 * 0: The Unit <OBJECT>
 * 1: Damage to Add <NUMBER>
 * 2: Selection ("head", "body", "hand_l", "hand_r", "leg_l", "leg_r") <STRING>
 * 3: Projectile Type <STRING>
 *
 * Return Value:
 * HandleDamage's return <NUMBER>
 *
 * Example:
 * [player, 0.8, "leg_r", "bullet"] call ace_medical_fnc_addDamageToUnit
 * [cursorTarget, 1, "body", "stab"] call ace_medical_fnc_addDamageToUnit
 *
 * Public: Yes
