Building city with pedestrians

Hello, I'm building a city with bunch of pedestrians wandering. This is project for mobile devices.
I've just started with Unity and I've a question about creating pedestrians objects. I consider two options:

1. Create all pedestrians on scene in whole city and designate them waypoints for wandering
2. Create spawners for pedestrians and spawn them depending on currently hero position and view

Of corse first option is the quickest and simplest one but I'm wonder about optimisation... Is Unity rendering an object that is out of Camera view?

 

If you are targeting mobile devices, you have to save all the performance you can.
Even for a highend desktop game, i would not even consider version 1, depending on how large your city is.

Go with version 2 and make sure that you pool your pedestrians, so you are not triggering the garbage collector all the time.

 

Thanks for your feedback.

 

Note that pedesdrians (i assume humanoid people) are likely to be relatively expensive to render than static city building objects. Normally this would require a skinned articulated model etc. Of course this does depend on your art style and visual fidelity.

 

I've bought animated low-poly people from polyperfect on asset store. This will be good?

 

Sorry, i don't know. Probably the best thing to do is set up a simple test scene to see how many you can animate at the same time on your target hardware. To do this obviously you will need to build and deploy to a mobile device of the minimum spec you want to support. Good luck with your project.

 

thanks
