Mini-Nuke doesn't lag. No brick damage is somewhat handicapped, considering nuclear weapons are supposed to be destructive.
However your model is superb, as was previously stated. I'll edit the script for my own purpose if I feel the need to.
you CANNOT be loving serious
okay
get this through your thick skull
I can handle 256,000 bricks at a time in blockland
I run a computer that can run Crysis and Crysis 2 on MAX graphics, and doesen't lag at all, I can shoot a mininuke or an ion-cannon at a build that is at least 10,000 bricks and lag like forget, there are just some things in blockland not even the best computer in the world can help, the engine is really old
PLEASE don't add brick damage, even with an explosion half the size of the fatman it would still be pretty bad :/, also, theres no actual damage other than to players and props in fallout, so it would be kind of authentic
