I don't believe so. The last parameter is for player information specifically. If you just want to store an int variable that pertains to a specific module then you'd just do something like:
void main()
{
string sMod = GetName(GetModule());
SetCampaignInt(sMod, "awesomelevel", 100);
}
But if you want to store an int variable about a specific character in a specific module then you'd do something like:
void main()
{
string sMod = GetName(GetModule());
object oPC = GetLastUsedBy();
SetCampaignInt(sMod, "awesomelevel", 50, oPC);
}
