How configure alarms? [Multiplayer servers]

[mc sd 0]

Hi,

 

I am trying to implement an alarm system in my base using triggers, but I don't know how to create the code / logic ... can anyone help me, plz?

 

So far I've done these triggers:

 

Setup triggers:

• Setup alarm
• Setup turn on
• Setup turn off
• Loudspeaker

 

 

 

Turn on alarm:

• OPFOR is in the area
• BLUEFOR is in the area
• INDEPENDENT has been detected by OPFOR
• INDEPENDENT was detected by BLUEFOR

 

 

 

Turn off Alarm :

• OPFOR left the area
• BLUEFOR left the area

(if there is 1 bluefor and 1 opfor in the area and only 1 leave, the alarm stops ringing - I need to fix it)

 

 

 

But I'm having critical issues with these triggers:

•  Another INDEPENDENT team is in the area (the trigger is activated even if it is only me in the area)
•  Another INDEPENDENT team detected me (same problem as above)

 

 

I imagine that the ideal and simplest logic would be to check if there are more than 1 group in place to trigger the alarm, is it possible to configure a trigger to do this?
