Aerotopia: How I render 1000 NPCs at 60 FPS

[@lion3312]

Lets say hypothetically that every npc is made of one mesh.

[@maxgorden499]

Thanks for all the content you provide :) Never understood how to implement if an object is in view or not, now I do! Thank you

[@gerardt3284]

I'm working on being able to handle 1000 NPCs on screen all at once, all crowding around the player and not going inside each other

[@ilittlebig198]

I'm also handling my npcs like this

[@gryphoncook5338]

it would be nice if we had all the variables definitions too

[@Fezezen]

local tick = tick

[@jamesmann260]

Interested to see where this goes.

[@elocore1702]

What is the % Activity you get from the script while this is running from the script performance tab

[@Fujui]

How would i do this with alot of logic per npc, like deepwoken?

[@kevintst2]

So clever

[@etrevi]

can you make a tutorial on this?

[@Fezezen]

How are you "hiding" them once they go off screen? Are you deleting their model? If so, wouldn't re-adding their model once they're on screen again, bring down the performance?

[@uppishowl3456]

He is "Hiding" them. It's exactly what it says. He's making it so it isn't visible anymore. Now, this can be done plenty of ways. I'd say the method he's doing is changing the parent back and forth through replicated storage and something in the workspace so he doesn't have to change the transparency of EVERY SINGLE PART each time. That's what I think he's doing anyways.

[@r0lfu_]

he said he was setting transparency to 1

[@unusuallight4959]

How are you running the client method? Do you have a local script that handles all of the client stuff or do you do it some other way

[@loganhunt3074]

Do you tell the server to update their location at all or is movement completely client side?

[@sleitnick1]

Both. The client handles it at high frequency, and updates the server every second (only if moving). The server then validates the movement (i.e. prevent exploits)

[@loganhunt3074]

How would you handle this system if there were multiple people in a server? I understand that what you have is based purely for singleplayer games but what would you do to change it so that different viewports would be able to view and update npcs within any of these viewports.

[@weirdthings9583]

May I ask why you are not just using 'NPC.Humanoid:MoveTo(Goal.Position)? Is it for performence? That is my only guess.

[@catgirlinspace]

How are you checking if the NPC is within the viewport?

[@sleitnick1]

At the beginning of this video, look at line 182 and 183

[@catgirlinspace]

ROBLOXcrazyman32 So there is a use for that function. I always thought that the WorldToViewPoint function was useless.

[@shokobata]

So basically u are just rendering and calculating npcs that are on screen

[@sleitnick1]

Pretty much. Every NPC is having its new position updated and such, but not actually applied until that position is on screen

[@shokobata]

ROBLOXcrazyman32 OK thank you I should try something like that
