I made a tycoon, hotel tycoon, and npcs come and go, the thing is, there r over a 100 npc
I saw a game called theme park tycoon 2, those npc’s are cool, animated and no lag at all
How do I make one npc like that?
And I heard humanoids are costly, they need alot of disk space and ram on your device
I’m guessing they used some sort of custom humanoids then?
Sorry if this sounds stupid.
I am pretty sure that the ones that theme park tycoon use are not models but scripted npcs so scripts with create the npc then delete it and it goes in a cycle I might be very very wrong but I just guessed it and it also makes sense why there is no lag
Theme park tycoon most likley have already created npc templates and use math.random to spawn them. They use pathfinding to go around and what not.
I would suggest you use the Pathfinding Service.
As for the animations you can create custom animations for the character and assign it to the walking/running animation.
Hope this helps! 
wth uh I made an npc, and it works too, and you know they all work, they are moving too, but the thing is, the npc are made from humanoids, too many customers ( too many npcs) can affect client performance
And I want to replicate this game on a much grander scale, with over 5k to 10k humanoids, this will affect all the players performance including server
So I would like to know if there is a good way for making npc, not about making the npc system
Yes, I am asking how to make a npc template
Ahhh, I see, sorry I was misunderstanding. Rather than making a new humanoid, maybe try using LODs to increase proformance.
Hope this helps!
