Mission Parameters – Arma 3

Server admin / host can customize multiplayer missions in ROLE ASSIGNMENT menu using parameters prepared by the mission designer.

Manual Params

Params are defined in description.ext.

class Params
{
	class AISkill
	{
		title = "AI Skill"; // Param name visible in the list
		values[] = {0.2,0.6,1}; // Description of each selectable item
		texts[] = {"Recruit","Regular","Veteran"}; // Item values, can be only integers; the array has to have the same number of elements as 'texts'
		default = 0.6; // Default value; must be listed in 'values' array, otherwise 0 is used
	};
	class Daytime
	{
		title = "Time";
		texts[] = {"Morning","Day","Evening","Night"};
		values[] = {6,12,18,0};
		default = 12;
		function = "BIS_fnc_paramDaytime"; // (Optional) Function called upon mission start, selected value is passed as an argument
	};
	class ViewDistance
	{
		title = "View distance (in metres)";
		values[] = {500,1000,2000,5000};
		// When 'texts' are missing, values will be displayed directly instead
		default = 1000;
		file = "setViewDistance.sqf"; // (Optional) Script called upon mission start, selected value is passed as an argument
	};
};

Selected values are stored in paramsArray array, accessible anytime during the mission on any connected computer. Their order is the same as is in description.cfg (for example, params above would result in [12,1] if default values were kept).

Example (can be used in init.sqf):

if (isServer) then {
	_skill = paramsArray select 0;
	{
		_x setSkill _skill;
	} forEach allUnits;
};

setViewDistance.sqf:

setViewDistance (_this select 0);
