well, for a start ya could remove the other weapons, just to FORCE the bird to use a certain missile.
INIT field goes like:
This removemagazines "Machinegun30A10" .... etc.
...so that ONLY the maverick is left.
Then a kill command - MyPlane doTarget "Object ID#"; MyPlane Fire "MaverickLauncher"
- or alike.
Not sure if the bird will target that house, though, as its prolly a CIVIL sided building.
you could try ;
birdD dowatch "MyHouse" (or object ID#); bird fire "MaverickLauncher"
try it fer size m8
=========
PS: "birdD" is the Driver of the plane named "bird"
