Integration with Uni Bullet Hell

If they've got integration then you should ask them. I've never used that plug in or worked on integration for it.

Correct that you should not use any destroy scripts on anything that you'll be pulling or it will no longer pool obviously.

The listeners scripts are only needed if you're going to add some custom code to pool bus events. I doubt you need to do that.

You do have a pool boss game object in your scene right?

Wow hey, thanks for the quick replies! Let me show you guys what I'm working with here. So for the sake of getting it to work, I'm only pooling player bullets and enemy bullets. Here's the screenshot of my PoolBoss setup for this particular instance cl.ly/786611342e15
I've got 200 enemy bullets and 100 player bullets set to recycle the oldest (which I'm assuming means I can completely remove my destroy/disable borders along the edges of the level).

Then I'm using UbhObjectPool.cs (which can be found alongside some other singletons from this package which I also have no idea what they do here drive.google.com/open?id=1CfA-fZv9Mw4QCdmyrnQWCw--crCYoidq) when enabled it asks me to set up pooling settings as well, as seen here: cl.ly/06cd93ce28d5 but never asks for a category or anything.

It seems really redundant to set up pooling settings in two places. The dev that makes UBH isn't very responsive and in his one reply so far hasn't said anything about how to make this work. The tutorial on their site is specifically about assigning shot patterns to objects and not about any of this other stuff so thanks in advance for already being responsive

Dang, well thanks for checking this out. I'll keep plucking away. Hopefully Oshigawa responds soon!

So I stumbled on the answer. UbhObjectPool is attached to the game object where the pooled items get stored when they're instantiated in the scene. Because these are bullets in a shooter, they start off in PoolBoss and get sent to UbhObjectPool as they're fired and using Recycle Oldest lets me keep cycling them. I was getting thrown off by the custom object pools in UbhObjectPool because it comes with it's own pooling script... but if you un-comment the part about Core GameKit then it uses PoolBoss and putting anything into these fields breaks the whole thing.

tl;dr if I just set the Ubh script and ignored it I would've been fine. 

Because I'm now using PoolBoss with my projectiles, what function would I call to return a projectile to the pool? The main example is when a projectile hits an enemy, it needs to leave the scene view and return to the pool for future use. If I disable or destroy it, it doesn't come back.  

I don't mean to keep bugging you - if there's a better way to ask these kinds of questions please let me know. But when I use that function it's like it takes them out of the pool. Here's a gif of what's going on: cl.ly/b6aee3d79f15

For this example, I set the pool to be 5 and recycle the oldest. If I just fire into nothing it recycles those 5 over and over, but I've got it set on collision to call PoolBoss.Despawn( self ) when it hits the enemy. It looks like it creates game objects for the children of the prefab, but it doesn't recycle my bullets as I would expect; it just stops firing.
I also noticed the option to "Keep Parent" and when that is active it doesn't work either. Am I missing something here?

Nope, it just says "No clones left to spawn in PoolBoss" and I can't shoot anymore.

Was a bug on their end, check out patch notes for 1.4.2
