1) Use FCNPC , they are very useful , you can use a callback "FCNPC_AimAt" to allow NPC to Shoot . Click Here To Redirect.

2) Create gates by CreateObject and make a code (i don't know exact about explosion in 5m but it think it will be similar like CreateExplosion(x, y, z, 12, 10.0); ,or maybe exact ) Ok then use MoveObject .
