I want to create an AA rocket that takes down chopper?

is there a way to create a rocket somewhere (without a visible in-game source like an AA soldier), that hits the player chopper?

Thanks in advance for any help.

You're looking for setHit. Just destroy the motor or rotor or whatever part that gives you the desired crash.

Execute it from somewhere with that first bold line

[Targetname, [(markerPos "missileStart") select 0, (markerPos "missileStart") select 1, 5], "M_Igla_AA", 500, position someObject] execVM "launchMissile.sqf";

obviously substituting the object and marker names for your own.

The ----- mission-specific!!! part at the bottom just destroys the target's tail rotor if it is a chopper.

Only call it from the radio or addAction????

I want it to work by setteing an latancy trigger,What could I do ?

well you can create a trigger and put execVM "launchmissile.sqf" in the on activation screen, and you can than make a script that checks the altitude and execute that in the condition field
