Condense multiple realtime placed prefabs into a single one

[tacit garden]

I am generating a map with small tile-like prefabs, and therefore, in some cases I place hundreds, and in some tens of thousands of GameObjects...
Assuming I compress all my prefabs into a single GameObject each(with something like ProBuilder), it would still be too much, is there a way to turn all my Realtime placed Prefabs into one single big GameObject?

and that is a TINY map

[tacit garden]

After merging all the GameObjects in each prefab into a single object + removing the floor from each tile to place a big floor under the whole thing(only works in prototype because in a real map you'd prob have variations in the floor but we'll see), redueced batches by half

However if I can somehow merge all 200 tiles (and therefore gameobjects) on screen into a single one I imagine it'd save much more??
(and again 200 is a tiny example, usually there'd be much more)

This is a bigger map, Idk if I'd even make maps as big as that(tho I've made much bigger for the funny) but the stats aren't promising
(Last one was 20x10, this one is 60x30)

@tacit garden how are you measuring performance?

[tacit garden]

Oh- I'm not
I haven't checked performance or lag, I just noticed there's a crazy amount of batches

and I'm pretty sure it's best to decrease them

[vague nacelle]

So premature optimization...

Not even optimization you're just reducing a number

[tacit garden]

Well the larest map I tried to make was a 400x30

oh wait no that was without placing GameObjects

the laregest game object one was the funny one, 200x100

that's 20k Tiles, which (before merging), was approx 80k game objects in a scene

it doesn't sound ideal at all lol

I need to measure how much time was Unity starting the game and how much was the generation and how much was instantiation for a better idea I suppose

[vague nacelle]

don't assume

[tacit garden]

I just opened the profiler

but there's so much going on I can't even find my script in there nor a search function

Imma go look at how they work lol

[vague nacelle]

turn on deep profile

[tacit garden]

oooh

where is it?

[vague nacelle]

and use hierarchy mode or something like that

but I would continue working on features rather than optimizing

this would just be for your own interest

[tacit garden]

Fair I suppose, it's prob not even a me issue but like a RAM issue from me (ig it is a me issue) having lots of shit open, but pressing start took like a solid 30 seconds to load

now it takes way less(it was last night)

but it made me wake up with the desire to fix that lol

prob better moving on

tho good stuff to know

[tacit garden]

so for future reference, where do I turn that on?

[vague nacelle]

it's a button kind of at the top

[vague nacelle]

can you explain more?

this impacts dev

[tacit garden]

You'd press start, and it'd load the scene for like 30 seconds lol

way more than earlier that day or today

[vague nacelle]

What changes were made

[tacit garden]

Well... now I reduced the game objects in each prefab to one each, but I imagine just my PC getting some rest llol

[vague nacelle]

You mean there's a cost for generating the scene? And you suspect that this is due to the number of game objects?

[tacit garden]

maybe something I had on was memory leaking and caught a lot of RAM

[tacit garden]

I wasn't sure, and always good to reduce those I suppose

messing with the prefabs was easy enough to not mind doing anyways

[vague nacelle]

Ok

For future reference, you'll probably want to do some kind of mesh generation or merging to reduce the number of tris and verts in your scene

[tacit garden]

yupp I imagine I would

No idea how that works yet(pretty sure I've done that once a few years ago on smth not sure) but when the time comes i'll take care of it

I found the deep profile button too, so thank you
