I have a issue about Tweening Part Orientation! (-180 to +180)

[xccosanxcc]

I understood the problem, for example, since it changes from -180 to +180, it needs to rotate 360 degrees, but how can I solve this problem?

code:

local TweenService = game:GetService("TweenService")
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")

local Character = script.Parent
local HumRootPart = Character.HumanoidRootPart

local function findTarget()
	local players = Players:GetPlayers()
	local maxDistance = math.huge
	local nearestTarget

	for _,Player: Player in pairs(players) do
		if Player.Character then
			local target = Player.Character
			local Hum = target:FindFirstChild("Humanoid")
			if not Hum or Hum.Health == 0 then continue end

			local distance = (HumRootPart.Position - target.HumanoidRootPart.Position).Magnitude

			if distance < maxDistance then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end

	return nearestTarget
end
function CFrameToOrientation(cf)
	local rx, ry, rz = cf:ToOrientation()
	return Vector3.new(math.deg(rx), math.deg(ry), math.deg(rz))
end
local Tween: Tween
local function lookAtPlayer(target)
	local Goal = CFrame.lookAt(HumRootPart.Position, target.HumanoidRootPart.Position * Vector3.new(1, 0, 1) + HumRootPart.Position * Vector3.new(0, 1, 0))
	Goal = CFrameToOrientation(Goal)
	Tween = TweenService:Create(HumRootPart, TweenInfo.new(1,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{Orientation=Goal})
	Tween:Play()
end
local function Loop()
	local target = findTarget()
	if target then
		lookAtPlayer(target)
	end
end

You can tween the CFrame using CFrame.Angles, and you can set it to radians more than pi (which is 180 in degrees).

The same problems occur when used in CFrame.lookAt, what does it matter if using CFrame.Angles? won’t the same thing happen? and I didn’t understand how to use it with CFrame.lookAt

I personally wouldn’t use TweenService as it just reset the orientation back when turning too much. This is what i came up with but you can always change things if you’d like. Replace your lookAtPlayer function with the following.

local function lookAtPlayer(target)
	target:SetPrimaryPartCFrame(CFrame.lookAt(
		target.HumanoidRootPart.Position,
		HumRootPart.Position * Vector3.new(1, 0, 1)
			+ target.HumanoidRootPart.Position * Vector3.new(0, 1, 0)
		))
end

Hope I helped!

when i try this CFrame.lookAt on tween nothing changes

I found a way using what you said, but I’m not sure I’m using it correctly. Works fine apart from that.

local function lookAtPlayer(target: Model) -- target = Character
	local oldCF = HumRootPart.CFrame -- npc HumRootPart
	local newCF: CFrame = CFrame.lookAt(HumRootPart.Position, target.HumanoidRootPart.Position * Vector3.new(1, 0, 1) + HumRootPart.Position * Vector3.new(0, 1, 0))
	local x1, y1, z1 = oldCF:ToEulerAnglesYXZ()
	local x2, y2, z2 = newCF:ToEulerAnglesYXZ()
	local x,y,z = x2-x1,y2-y1,z2-z1
	
	local Goal = oldCF * CFrame.Angles(x,y,z)
	Tween = TweenService:Create(HumRootPart, TweenInfo.new(1,Enum.EasingStyle.Quad,Enum.EasingDirection.Out),{CFrame=Goal})
	Tween:Play()
end
