First of all, I'll go over how the scriupt is initialized and what everything passed to the script means....
[groups,staticgroups,targetgroup,3,0.4] exec "grouplink.sqs"
When you initialize an instance of the script, there are three arrays of groups that are passed to the script - "groups" , "staticgroups", and "targetgroup".
"Groups" = groups that will be checking for the "targetgroup", and can call eachother for backup if they see the "targetgroup"
"staticgroups" = these are the groups in the first array (see above) that that call for backup but can not be called for backup.
"targetgroup" = this is the group that that all of the groups in the "groups" array (see above) are checking for.
If you put your group in the "groups" array when initializing the script, you will inevitably start getting the anoying radio chatter when you encouter the "targetgroup" or another group in the groups array calls you for backup.
The solution is to leave the group you will be in charge of OUT of the "groups" array, when intializing the script.
When you initialize the script, if you put your group as the "targetgroup" then you won't experience all of the radio chatter, because the targetgroup is the group being checked for, and not being called for backup.
OK, lets say that there are 5 groups on the map....
w1,w2,e1,e2,e3
Lets say your group is "w1".
Heres how you could initialize the scripts without getting the radio chatter.
[[e1,e2,e3],[],[w1],3,0.4] exec "grouplink.sqs"
What the above would do....
The groups e1,e2,and e3 would check for the group w1 (your group) and call eachother for backup if they spot your group.
I'm not sure how else to explain it. I've basically covered most of what is in the readme in this post.
As for the example mission...here is how you would keep "gw1" out of the groups arrays when inistializing the scripts....
"[_eastgroups,_eaststaticgroups,_x,3,0.5] exec {grouplink.sqs}" foreach _westgroups
"[_westgroups - [gw1],_weststaticgroups,_x,3,0.5] exec {grouplink.sqs}" foreach _eastgroups
However this would keep "gw1" from being able to call for backup or be called for backup.
