not sure about with such an early version of OFP....
if you had Resistance then you could get the object ID number of the building and then setdammage to it
I think the best you can do is make a gamelogic on your building and then camcreate a laserguided bomb ( are LGB's even in 1.0??) onto the spot and blowing up the building..
bomb="HEAT120" camcreate getpos g1
toss that in a trigger/script/waypoint and place a gamelogic named g1 on the spot you want the shell to appear.
the bit in quotes "HEAT120" can be changed to any valid shell type ...
you can try to use "LaserGuidedBomb" to get a proper explosion.. but I think that the LGB was added in 1.30 ?? or a following version...
you should really go to
www.flashpoint1985.com and get the patches to upgrade from 1.0 (actually you should buy resistance, but if not.. at least update your CwC )
