NPC Head Bugging Out

Help and Feedback Scripting Support

#1

The NPC’s in my game have localized head tracking to follow players when in-range. However, there has been a random bug occuring where the NPC’s head will fall into the NPC torso (see image below). I am not entirely sure why this is happening, my early assumption was that the joint didn’t exist early enough so I tried anchoring the heads until they need to be moved with no luck. The script below uses the default “Neck” Motor6D found in the character head.

Head Code

self.connections["head"] = RunService.Heartbeat:Connect(function()
		local character, root = GetLocalCharacter()

		if (not character) or (not root) then
			return
		end

		local direction = (CFrame.new(self.position,root.Position):Inverse() * self.cframe ).lookVector * -1

		if self.personality.UseYAxis then
			self.neck.C0 = CFrame.new(0, self.neck.C0.Y, 0) * CFrame.Angles(0, -math.asin(direction.x), 0) * CFrame.Angles(math.asin(direction.y), 0, 0)
		else
			self.neck.C0 = CFrame.new(0, self.neck.C0.Y, 0) * CFrame.Angles(0, -math.asin(direction.x), 0)
		end
	end)

Any help is much appreciated!

bump (character limit character limit)

Have you figured out a way to solve this yet? I do see a discrepancy in the math regarding like vectors / positioning?

#4

I have not, if you have any ideas it would be much appreciated!

Try using welding, like BodyVelocity or something like it
