Pathfinding Enemy NPC Help

[harsh jolt]

Hey, If anyone is good at created pathfinding npcs, Id really appreciate some help.
Ive been working on one for a while, and its a bit buggy and laggy when I have lots of enemies.

The NPC should do the following:

• Pathfind to the nearest player
• If any walls are detected to be in the way, break them and continue
• Deal damage when in range of player

However problems im dealing with are:

• Npc will randomly stop
• When having lots of enemies the game lags
• Animations are laggy

Heres my script:

looks like a solid start, main problem is you're using the newb trap human.MoveToFinished:Wait(3) -- timeout after 1.5 seconds do it properly: https://create.roblox.com/docs/characters/pathfinding

just search the player who has a nearest position with the npc, thats not a big biggie

Also any tips for efficiency?
I Want to be able to have as many enemy npcs as possible at the same time, currently there is a copy of the script in every one.
Anything I can do to reduce lag?
