Error Free Destroy Animations

It's very simple actually.

[GACNST]
DeathWeapon=AlliedYardExp
Explodes=yes

[AlliedYardExp]
Damage=1
Range=1
Speed=100
Warhead=AlliedYardWH
Report=ExplosionBarrel <- not needed but sounds appropriate

Then make warhead with verses set to 0% and AnimList set to the desired animation.
You can add the screen shake for a nice touch but it's not necessary.
