#

im tryinbg to make the npc rotate to face what angle im coming from and then push me away when i walk up to them

( I HAVE THE PUSH AND STUN, JUST NEED ROTATION )

#

the code

#

ping me when you help

jade fulcrum Sep 21, 2025, 5:02 PM

#

knotty crescent the code

Simple

#

To have rotation

#

U just

#

Set it's cframe

#

As 2nd argument is lookat

#

So just update cframe

knotty crescent Sep 21, 2025, 5:03 PM

#

how do i do that

#

can u rewrite it for me @jade fulcrum

jade fulcrum Sep 21, 2025, 5:07 PM

#

knotty crescent y

Set the cframe to cframe.new(hrp.postion, playershrp.posiiton)

#

Simple

knotty crescent Sep 21, 2025, 5:07 PM

#

how do i do that

#

is it this line

#

local targetCFrame = CFrame.new(npcHRP.Position, Vector3.new(hrp.Position.X, npcHRP.Position.Y, hrp.Position.Z))
npcHRP.CFrame = npcHRP.CFrame:Lerp(targetCFrame, ROTATE_SPEED * deltaTime)

jade fulcrum Sep 21, 2025, 5:10 PM

#

jade fulcrum Set the cframe to cframe.new(hrp.postion, playershrp.posiiton)

Bud

#

If you wrote the script

#

U will know

#

I litteraly have u whole ass code

knotty crescent Sep 21, 2025, 5:10 PM

#

can u just help

jade fulcrum Sep 21, 2025, 5:10 PM

try this

where would i insert it?

should be instead of trhis

knotty crescent Sep 21, 2025, 5:44 PM

#

so replace this with

this

knotty crescent i just put that in

yes

knotty crescent Sep 21, 2025, 5:45 PM

#

but they dont like rotate

#

like if i approach from behind

#

theyre supposed to turn around and face me and push

#

as soon as i make contact

still no

#

the detection range is how close you have to be to push

#

can i js add u to studio

#

@knotty crescent you didnt add me to the experience i dont think

#

also i think you should add it so

they look at you from say 50 studs
but push you at say 10 studs

#

im not sure if that was your issue but currently when i run your code they will only face me when they also push me

#

put it into multiple functions to make the flow easier to read

#

made it so they will turn at you in a certain range and push you in another certain range

#

you can config pretty easily

#

this is specifically for one NPC but you can add your folder logic in the Heartbeat function

#npc rotation and push away
