So basically
I have an idea of how this will work
I want to make a gun that shoots guns that explode into grenades that explode into more guns that shoot grenades that explode into more grenades etc. etc.
I figure it is probably as simple as changing the gibs and the fired bullet from a rocket launcher template, but I need to know how to set a fuse on an explosive, so like the first round will explode on contact, then the guns gibbed from that explosion will bounce around for a few seconds, then explode into contact grenades and so forth
Lag doesn't matter too much
A bonus would be making the grenades actually be fired from the guns (like 3 rounds, then the gun gibs into normal debris) but if that requires a lot of scripting which I know it will and no one can be assed to make that for me because my grasp of lua is practically nonexistant

I know there was a mod here somewhere that had a gun that shot blunderbusses but I lost it

Just make the "gun" be an AEmitter that shoots off grenades that recurse back into the gun.

It's a bit tricky, but entirely possible to do entirely with .ini code.

I don't want it to loop endlessly, I want there to be an eventual end to it, but just a good way down the line
I figured I would have to use emitters for it though

I think it would be easier to do .ini recursion with a Lua script to delete the ones you don't want to recurse.
