See demo mission.
Else, in a description.ext, paste:
class Params
{
class skipTime
{
title = "time to skip";
values[] = {0.5, 1.5, 2.5};
texts[] = {"1h30", "1h30", "2h30"};
default = 1.5;
};
};
in init.sqf, paste:
hint str paramsArray;
skipTime (paramsArray select 0);
this will skip 2 hours as paramsArray already converted the value 1.5 to 2 as seen in the hint.
(you can do this in SP as Arma 3 takes paramsArray in consideration.)
