I might have missed it? I'm looking for tips on how to reduce block damage from rocket launchers/dynamite. Is this done through items? I'm looking for the damage to blocks to be either 0 or very close to 0.
in the item.xml search for ammorockethe and ammorocketfrag. each has an entry for blockdamage. You can set it to 0 or 1 or 10000 and crank up the explosion radius to a crazy level and see if the world or your computer blows up first.
