I'm looking for a grenade that summons multiple smaller grenades when it hits a surface. A real cluster grenade, but to keep it safe:

It only summons other grenades once, and the summoned grenades have less damage and blast radius than the thrown grenade, about the blast power and radius of the grenade launcher in Halo: CMT Campaign Mode V1.

The summoned grenades would also need to have randomized delay times before exploding and have zero rebound after summoning - in other words, they hit the ground like a dead body. Removing their ability to bounce would prevent them from summoning even more grenades, I assume, but would also make it difficult to spread them out unless the grenade hits a high wall.

It doesn't matter if they're Fragmentation or Plasma.

You might be able to accomplish this by setting a spawn trigger effect for when the grenade encounters a surface on which you want it to fragment or 'summon'. I would look under the projectile tag (I think) for penetration/bounce properties, and if there is an opportunity to provide an effect, create one that spawns more grenades (of the 'summon' type you create) as projectiles, which should in theory be propelled along values you specify in the grenade projectile tag.

You might also look at figuring out how to 'destroy' the grenade on contact, as I am sure you can spawn objects as a special effect upon destruction (from what I could tell, this is how Carrier Forms release their incubated Infection Forms on death); this option should also allow you to add smoke to the resulting 'summon'.

Thank you very much! This will come in handy when I get back to my project.

I have one other question: Could I apply the same effects to the rocket launcher? Only all the rockets would fire off at once, and the smaller rockets would fire off at slight angles.

EDIT: Actually, I think I'll keep it simple. Since I already know the Plasma Grenade has a bounce effect, I think I'll remove the adhesive part and replace it with a frag grenade spawn.

This way, the plasma grenade spawns cluster grenades, but that ability doesn't carry over to the spawned grenades.

Good stuff.

After I posted this, I gave it a try. I experimented with both dropped frag grenades (which are dropped when an enemy is killed) and active frag grenades, and I think I prefer the dropped frag spawn. The active frag spawn makes it too easy to throw the plasma grenade back into the air, and I still haven't figured out how to make it summon grenades with just one bounce.

Thanks again, by the way!
