Alright so, I have the grenades as GetsHitByMos = 1 so they are recognized by lua, but when the actor that dies has one in it's inventory, it explodes violently all over the place.

Is there a fix to this problem?

Have the explosion on an MOSRotating that is spawned by a script on the grenade based on a timer.

So if the grenade gets destroyed before the timer goes off, no explosion.

Yes and no.
You'll have to set ActivatesWhenReleased = 1 to ActivatesWhenReleased = 0 in the TDExplosive's .ini file. This keeps it from exploding spontaneously after an actor's death.

Keep in mind though, when some actor uses its big butt to push a grenade into the ground it'll most likely go off no matter what you try to do about it.

While that was fun, it's not always the case now. Look at the new grenades, they have gibs, and separately, they have script initiated explosions that don't happen when they gib, which is what CC48 was talking about. This was also possible to achieve with emitters, in the past.

The ActivatesWhenReleased = 0 thing worked to solve the issue with the grenades exploding on death, now they just go off when they're touched by nearly anything. I guess I'll try setting the GibImpulseLimit super high, and see how that turns out.

I think that's lame. I would much rather shoot a grenade in someones had and blow em up.

Then don't use what I said. Problem solved.

I'm making a sly game suggestion.

Abdul made that change, not me.
