A cool and smart zombie AI. Note this is not really meant to be added in an actual game, it is just the best implementation of Roblox’s pathfinding I could figure out.
There is no damage for the zombies because this is for testing only.

There is no visible lag/stuttering in the zombie movements.
Roblox’s pathfinding isn’t so bad after all if the implementation is correct. Have a look at this:
