please comment!

Works how it's supposed to, no problems with the explosion triggering. I suggest you make the shrapnel go away over time. I have a simple code you can put into the circle spawning script:

;controlleracc := sim.time + X; density := {controlleracc<sim.time?{0}:{Y}}

Place that into your spawning script, change X to be how long you want the shrapnel to last (goes by seconds), and change Y to whatever you want your shrapnel density to be.

Hope this helps with your grenade.

Thanks for your advice FruitMonger! and nice script! i will upload not infinite version

oopps sorry FruitMonger the script didn't work for me so i just added "d" key for destroy key! Thanks for idea the new version is "motion detact infinite nuclear missile v.2"
