Okay, if anyone here has played UT2004 & used the SPMA artillery mode, they may get it:
I want it to split open about 50 feet above the target, and release smaller shells, about 6 shells. How would I rig it to do this...
OCL's are your friend. Use a HeightDie on the parent shell, and spawn 6 other shells via OCL. On that OCL, you can use Disposition and DispositionIntensity to regulate how far the shells are flung outwards.
