checking for Group membership

Hey everyone;

I've got this opensource camping script that I want to modify to check for a specific active group. The script works well as it is now, I just want to make sure that only members make use of the camping device. Can someone show me how to modify this script?


// Begin Code //
integer campmoney = 0;
integer campadd = 1;
integer camptime = 60;
string reciever;
string sittext1 = "sit here for free money ,\nL$";
string sittext2 = " every 1 minutes";

string camptext = "Paying L$10/10min. ";
string sittext;
integer currenttime = 0;
//
default
{
state_entry()
{
sittext = sittext1 +(string)campadd+ sittext2 ;
llRequestPermissions(llGetOwner(),PERMISSION_DEBIT );
llSetText(sittext,<0,1,0>,1);
llSitTarget(<0.4, 0, 0.6>, ZERO_ROTATION);
}

on_rez(integer start_param)
{
llResetScript();
}

changed(integer change)
{
if (change & CHANGED_LINK)
{
if (llAvatarOnSitTarget() != NULL_KEY)
{
reciever = llAvatarOnSitTarget();
llSetText(camptext+(string)campmoney,<0,1,0>,1);
llSetTimerEvent(camptime);
}
else
{
llGiveMoney(reciever,campmoney);
reciever="";
campmoney=0;
llSetText(sittext,<0,1,0>,1);
llSetTimerEvent(100000000);
}
}
}
timer()
{
campmoney = campmoney+campadd;
llSetText(camptext + llKey2Name(reciever) + " has earned $" + (string)campmoney + "L so far." ,<0,1,0>,1);
if (llAvatarOnSitTarget() != NULL_KEY)
{
}
else
{
reciever="";
campmoney=0;
llSetText(sittext,<0,1,0>,1);
}
currenttime++;
llOwnerSay((string)currenttime);
if(currenttime == 10)
{
llUnSit(llAvatarOnSitTarget()); // unsit him
currenttime = 0;
}
}

run_time_permissions(integer perms)
{
if(perms & PERMISSION_DEBIT)
{
llSetText(sittext,<0,1,0>,1);
}
else
{//Permissions was denied.
llSetText("OFFLINE",<1,0,0>,1);
llRequestPermissions(llGetOwner(),PERMISSION_DEBIT );
}
}
}

//End Code //

After getting the AV's key ( reciever = llAvatarOnSitTarget(); ), check llSameGroup(reciever).

And note, this requires the camper to wear the tag of the group at the time, as this is all that LSL can check for, group-wise.

To further clarify things:

You cannot check if a specific group is active.

Scripts can only check if the interacting individual is in the *same* group as the object with the script in it.

Would it be possible to twist this a little, marry it to a visiter tracker and only log those visitors who are NOT group members?

yup, but again, it'll still count them if their active tag isn't the same as the object

sensor( integer vIntSensed ){
  do{
	--vIntSensed;
	if (!llDetectedGroup(vIntSensed)){
	  //-- logging code
	}
  }while (vIntSensed);
}
