#include "script_component.hpp"
/*
 * Author: PabstMirror
 * Shows multiple watched variables on the main display (for easy debugging).
 *
 * Arguments:
 * 0: Title (var name) <STRING> (default: "")
 * 1: Code to generate result (passed nothing, can return any) <CODE> (default: {})
 * 2: Array containing modifiers <ARRAY> (default: [])
 * For Numbers:
 *      0: Show Delta change <BOOL> (default: true)
 *      1: Slider Min Value <NUMBER> (default: 0)
 *      1: Slider Max Value <NUMBER> (default: 0)
 * For Anything else:
 *      0: Number of structured text lines <NUMBER> (default: 1)
 *
 * Return Value:
 * None
 *
 * Example:
 * ["CBA_missionTime"] call ace_common_fnc_watchVariable // Uses title as code
 * ["diag_frameNo", {diag_frameNo}, [false]] call ace_common_fnc_watchVariable // Won't show delta
 * ["blood", {player getVariable "ace_medical_bloodVolume"}, [true, 0, 100]] call ace_common_fnc_watchVariable // Shows slider
 * ["multiLine text", {"Line 1 <br/>Line 2"}, [2]] call ace_common_fnc_watchVariable
 * ["player names", {allPlayers apply {name _x}}, [5]] call ace_common_fnc_watchVariable // handles any data types
 *
 * Public: Yes
