How Many AI Agents can JavaScript Handle?

How Many AI Agents can JavaScript Handle?

Inspired by Brackeys's video "How Many AI Agents can Unity Handle?", I decided it'd be fun to try a JavaScript version, with a bunch of work thrown at a* optimization, generation JavaScript optimization, and a little (lot) of cheating.

I walk through the steps of getting this all working, starting with a maze generation implementation, and an a* implementation. I reuse the code from my boids implementation but with a path following behaviour added, and finally we look at a* optimization and general javascript optimization to improve the framerate.

Thanks to Yocto Coding for pointing some problems out with the last upload, editing videos under lockdown and kids running around the house is hard!

I am genuinely astonished that a lot of your videos have only a few thousand views. The topics you cover are incredibly interesting and your presentation of them are really well-balanced. Good luck with the channel!

[jamisongriffith]

You're a badass. The fact you kept optimizing after you hit 4000 agents is inspiring. Great project and video

[ajlightning]

Wow I had no clue doing your own matrix calcs would improve things so much. Definitely curious on what other performance you can squeeze out

[danesmith]

This is amazing, hoping to make a lot of little ai guys like this in game someday

[Rssks]

You've got a new sub ;) keep exploring, experimenting and inventing!

[nury]

Simon your skills are impressive great work buddy, keep it up 👍🏻

[aliphian]

I just found your channel. I will be watching every video now.

You're awesome, huge thanks for sharing code with us!

God damn you are good. I didn't even know JavaScript could do this

[Chadderbox]

I've been interested in A* for a bit. I might have to take a deeper look.

Would be cool to see optimization of all those boids affecting grid so they can't go through each other and avoid collision.

May would be interesting, not only for me:
Place a red army on the left and a blue army on the right. Both have to pass by a maze to get to the middle of the map. There, the agents are trying to kill the other. interesting for me would be, what impact would that have? Finding near enemies and what impact on the performance side would have fired lasers or bullets have. And also implementing particles when an agent gets destroyed would have a massive impact to the framerate?

Would love to see something like that :)

I live for JavaScript. I beleive it’s perfect for the kind of games I’ll be making. One day I’ll learn c++ but that’s when I want to tackle giant games

[cmcdonough]

That's awesome, very interesting thanks.

Fellow js dev here, like what you have done

How long does it take to make this ?

Keep up the great work

[WorstDeveloper]

60k is a lot for JavaScript. What kind of hardware were you using for this experiment?

[carlosrvillegaschazaro]

Is there a Table listing the CPUs vs Max Items rendering performance using javascript ? Otherwise you'll get "script it's taking too long "

[xKeray]

"unity is heavily optimized"
WRONG 😂

[DommageCollateral]

this looks like you used 2d a*. so its not really comparable. but nice work
