Try to execute code like these ones in the BIS' debug console :
0 spawn
{
sleep 2;
playScriptedMission
[
"Altis",
{
while {time < 10} do {hint str time; sleep 0.5;};
},
missionConfigFile
];
};
OR
0 spawn
{
sleep 2;
playScriptedMission
[
"Altis",
{
while {time < 10} do {hint str time; sleep 0.5;};
},
configfile >> "CfgMissions" >> "Cutscenes" >> "Credits"
];
};
OR
0 spawn
{
sleep 2;
playScriptedMission
[
"Altis",
{},
configfile >> "CfgMissions" >> "Cutscenes" >> "Credits"
];
};
