hi Crowey
I found this a bit helpful on one of the furms cant remeber which one:
Make a unit with enough satchels to blow that building.
Place a waypoint near building, that you wanna blow up. In "On activation" field type:
Code Sample
UnitName fire "PipeBombMuzzle"
then make another waypoint, where you want soldier to put another satchel with same text inside "On activation" field.
You can make as many those waypoints, as many satchels soldier has.
After you're done with placing bomb waypoints put a new waypoint with this in "On activation" field:
Code Sample
UnitName action ["TOUCHOFF", UnitName]
this will blow the bombs up, so put it far enough, so the soldier won't be killed by explosion.
