#REDIRECT [[Mission Parameters]]
 
Server admin / host can customize multiplayer missions in ROLE ASSIGNMENT menu using parameters prepared by the mission designer.
 
== Manual Params ==
=== Config ===
[[File:Arma3 Mission Parameters.png|thumb|Mission Parameters selection]]
Params are defined in [[description.ext]].
class Params
{
class AISkill
{
title = "AI Skill"; {{codecomment|// Param name visible in the list}}
values[] = {0.2,0.6,1}; {{codecomment|// Description of each selectable item}}
texts[] = {"Recruit","Regular","Veteran"}; {{codecomment|// Values; must be integers; has to have the same number of elements as 'texts'}}
default = 0.6; {{codecomment|// 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"; {{codecomment|// (Optional) [[Functions_Library_(Arma_3)|Function]] [[call]]ed upon mission start, selected value is passed as an argument}}
};
class ViewDistance
{
title = "View distance (in metres)";
values[] = {500,1000,2000,5000};
{{codecomment|// When 'texts' are missing, values will be displayed directly instead}}
default = 1000;
file = "setViewDistance.sqf"; {{codecomment|// (Optional) Script [[call]]ed upon mission start, selected value is passed as an argument}}
};
};
 
=== Mission ===
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);
 
=== Functions ===
When you're not sure about order of '''paramsArray''' items (e.g., in a module which can be used in any mission), you can use [[BIS_fnc_getParamValue]] to get value of a param with given classname.
 
_viewDistance = "ViewDistance" call BIS_fnc_getParamValue;
 
 
== Predefined Params ==
Arma 3 introduces a framework for defining commonly used params (e.g., time of the day or mission duration), which can be shared across multiple missions. Once included to description.ext, they will initialize automatically. Some of them can be further customized using specific [[PreProcessor_Commands|macros]].
 
class Params
{
#include "\a3\functions_f\Params\paramWeather.hpp"
#define TICKETS_DEFAULT 600
#include "\a3\functions_f\Params\paramRespawnTickets.hpp"
};
