mysatchel3="pipebomb" camcreate "format position"
I don't think you can blow them up afterwards (mysatchel1 doesn't work, Titan), so here's a way round : create a trigger with "true" in the condition field, put 300 in max, min and med, and this in the activation field :
shell1="shell73" camcreate getpos mysatchel1;
shell3="shell73" camcreate getpos mysatchel2;
shell3="shell73" camcreate getpos mysatchel3
You'll get a real big explosion
as this will also blow the satchel charges up.
Or you can make a unit put charges where you want, and then order it to touch them off :
_myunit fire ["put","pipebomb"] in the activation field of your WP
and, five minutes later (don't leave that unit too close !!!)
_myunit action ["TOUCHOFF"], for instance in another WP.
