Kill a monster is its spawner dies

[Daryn]

I'm working on a Micro-Missile spider. It spawns three loiter missiles, then when those see the player, they fire off micro-rockets and die. The trouble I'm having is, sometimes those loiter missiles hang around the map, so I'd like to tie them to the spider that spawned them so that when it's killed, they die too.

I've tried a few things, but my ZScript isn't quite there yet. Still very much a learning-as-I-go thing for me.

Here's what I have so far. I've omitted the Rocket and its trail's code, since there's nothing there that's relevant, it's just changing some sizes and values of the original rocket.

This doesn't work, well, the monster works, but the rocket shells don't die when the spider does. If anyone has suggestions, please, let me know. I've been at this a good while already, and not had a lot of luck.

Thanks. Stay safe, everyone.

There are several functions that can be used (in ZScript or DECORATE) that can manipulate individuals in a master/child relationship.

[wiki]A_KillChildren[/wiki] might be what you are looking for but, if not, look at the bottom of that page for several more links.

As long as you spawn your items using the parameters that set a master/child relationship, those functions should be available to you.

It looks like that worked, which makes the timer function unnecessary. I may implement something in there later, though. Thanks, Enjay, you've been a huge help over the years.
