Compare group key of avatar without llSameGroup or llDetectedGroup

// This script compares the avatar's active group to any specified group in the script and not the group the object has active. To check if an avatar's active group is the same as the object's active group use llSameGroup or llDetectedGroup.

// There is no direct way to get the active group key of an avatar but you can get the active group key of one of their attachements which is the same as the avatar's active group.

key groupId = "d1228743-d417-938b-db90-52081ed656ba"; // add the key of the group you would like to check if the avatar is a member of

default

        list attachments = llGetAttachedList(Toucher); // get the list of attachments the avatar is wearing
        key a = llList2Key(attachments,0); // get the key of the first attachment in the list
        list det = llGetObjectDetails(a, [OBJECT_GROUP]);
         // get the active group of the attachment as it will be the same as the active group of the avatar.
