Is there any website to teach scripting walking and convincing guest bots?

I have to make a game with Guests moving throughout a complicated map, want to make sure that they seems legit.

To make Guest Bots walk in a complicated map, you have to use Pathfinding. Pathfinding make the bot go to a certain place where ever it is. To learn about it, look in the Roblox Wiki:

To make the Guest Bots look convincing, you are going to have to make an animation. In Roblox Studio, go to the Animation Plugin. If you don't have it, get it in Roblox. To make an animation, look in the Roblox Wiki:

That's all I can do for you! The rest is all on you. Good Luck!
