RE: Your bombs;
however you are creating your bombs anyway, trigger or WP, script or whatever, use the same method as you are already to get the postions, either by This is a trigger, or GEtpos of a gamelogic. And alter the line thusly;
bomb="heat120" camcreate [Getpos LocationName Select 0, Getpos LocationName Select 1, (Getpos LocationName Select 2) +10]
Where the last number is the height in metres you want to create your bomb. You can also alter the name of the bomb to be created by altering the "heat120" part to the bomb you are already using. But to get it higher, just add in that last number.
