CFrame.LookAt() is causing weird teleportation issues

Help and Feedback Scripting Support

I have a script that makes an npc face a player before playing an animation. I use CFrame.LookAt() to change his direction, but for some reason, the code causes the dummy to teleport into the void under the map.

local pos = CFrame.lookAt(character.PrimaryPart.Position,Vector3.new(attacked.Character.PrimaryPart.Position.X,character.PrimaryPart.Position.Y,attacked.Character.PrimaryPart.Position.Z))
character:PivotTo(pos)

character is the npc, and attacked is the player

Try

local attackedCharacter = attacked.Character
local attackedPivotPosition = attackedCharacter:GetPivot().Position
character:PivotTo(CFrame.lookAt(attackedPivotPosition, Vector3.new(attackedPivotPosition.X, character:GetPivot().Position.Y, attackedPivotPosition.z)))
#3

That makes the character teleport to the attackedCharacter. I want him to stay in place and just look at him

#4

My bad,

local characterPivotPosition = character:GetPivot().Position
local attackedPivotPosition = attacked.Character:GetPivot().Position
character:PivotTo(CFrame.lookAt(characterPivotPosition, Vector3.new(attackedPivotPosition.X, characterPivotPosition.Y, attackedPivotPosition.Z)))

Hey, to fix this you can just do:

character:PivotTo(CFrame.new(character.PrimaryPart.Position, attacked.Character.PrimaryPart.Position))
#6

It still teleports him under the map

#7

Did you try my solution or EcoCrashed’s?

#8

Yours makes him teleport under the map. Eco’s makes him face the attacked, but if the attacked happens to be at a higher elevation, it makes him fall over

#9

Wait, this is my code how is that so?

A great way to do it is instead of using CFrame.LookAt, I do:

Enemy.HumanoidRootPart.CFrame = CFrame.new(Enemy.HumanoidRootPart.Position, Target.HumanoidRootPart.Position)

I normally don’t use CFrame.LookAt. Totally not because I’ve never really used it.

#11

I’m pretty sure those do the same thing.

#12

It does, tested his code out as well, and it seems to work the exact same way. Did you forget to set the primary part? If not, can you try character.PrimaryPart.CFrame = pos instead of character:PivotTo(pos)? It should just error if there is no primary part.

#13

Yeah, I didn’t doubt you lol but why not just use PivotTo()

#14

Hmm, I ran a few tests, and your code seems to work if this part of the script isn’t running.

character.RightHand:FindFirstChildWhichIsA("Motor6D").Enabled = false
character.RightHand.Anchored = true
character.RightHand.CFrame = character.PrimaryPart.CFrame * CFrame.new(2,2,-2)
local handtween = game:GetService('TweenService'):Create(character.RightHand,TweenInfo.new(.5,Enum.EasingStyle.Linear,Enum.EasingDirection.InOut,0,true),{Position = attacked.Character.PrimaryPart.Position})
handtween:Play()
touchable = true
handtween.Completed:Wait()
character.PrimaryPart.Anchored = true
touchable = false
character.RightHand.Anchored = false
character.RightHand:FindFirstChildWhichIsA("Motor6D").Enabled = true
character.PrimaryPart.Anchored = false

Is there anything in there that could somehow break him?

What’s the chance that the character’s and the target’s X and Z positions happen to be the same? If that happens, CFrame.lookAt will provide an unexpected result of NaN because you can’t really make one position look at itself

local pos = CFrame.lookAt(character.PrimaryPart.Position,Vector3.new(attacked.Character.PrimaryPart.Position.X,character.PrimaryPart.Position.Y,attacked.Character.PrimaryPart.Position.Z))
if pos == pos -- NaN isn't equal to itself
	character:PivotTo(pos)
end
#16

That makes sense, but no, they are at different X and Z values.
