I tried using sub-explosions yesterday to make a sun creating gun. It would create an explosion and then it's subexplosion would be an intermediate, and that intermediate explosion would be delayed and have the first main particle explosion as it's sub-explosion. This would create a controlled loop of explosions by timing the intermediate explosion to only happen after the first one dies off.
But, it would not loop. I tried making a bunch of sub-explosions to go along with the first one without any loops and none of the Subs would go off.
Then there's debris data, I know that it does work with the State Images (gunshells are Debris), but does it work with actual explosions? I was using the Empty.dts file in base/data/shapes/, but no actual debris (giant particle fireballs in this case) would appear when the explosion would go off.
