My day kinda slipped away from me. But here I am, working on things. Today I'm doing a little bit of cleanup.
My object pooling is great (is it? It's actually super-simple), but I was getting warnings in the console about the spawned objects being destroyed. Didn't wanna leave any memory leaks in there, so I decided now was the time to address it, before I get too far and forget or something.
The solution was actually pretty simple, although I did get it wrong at first.
My first approach was an object that lives through the entirety of the game, from the main menu on. It would hold a list of objects that had been instantiated and destroy them when the scene changed. Unfortunately, trying to trigger an event on scene change with Visual Scripting wasn't exactly easy. I couldn't bother to take the time to figure it out, so I went with another approach.
I took that same object, and instead of keeping it alive during the scene change, it would be destroyed with everything else. Then, I could just activate the On Destroyed node, and iterate through the list of instantiated objects to destroy them. I just have to make sure to drop this little buddy in any scene that instantiates anything (which is just about every scene probably).
