Want To Make A Rotating Tween While You Are Placing Tower (Tower Defense Game)

hello i have a tower defense game and normally if you want to place a tower you press R key and it rotates it but i want to tween that rotation so it looks more good i am a beginner scripter i did try some code but it didnt work as planned it spinned out of control when i pressed R key

Code when i tried adding tween (i tried from my own mind) :

		elseif input.KeyCode == Enum.KeyCode.R then
			local rotationSpeed = 10
			local rotationTweenInfo = TweenInfo.new(rotationSpeed, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut) 
			rotation += 90
			if rotation == 90 or 180 or -90 or -180 then
				local rotationTween = TweenService:Create(towerToSpawn.PrimaryPart, rotationTweenInfo, {Orientation = Vector3.new(0, rotation, 0)})
				rotationTween:Play()
			end

code when i did not add tween :

		elseif input.KeyCode == Enum.KeyCode.R then
			rotation += 90

i would recommend using cframe

#3

Instead of setting the orientation, try this:

{CFrame *= CFrame.Angles(0,rotation,0)}

You wanna multiply (ie. add) a rotation instead of setting a new one to rotate the tower

#4

When i add the multiplication or addition it underlines the mathematical symbols in red (marks it as invalid)

Edit : tried this code and didn’t work either;

	local TargetCFrame = towerToSpawn.PrimaryPart.CFrame * CFrame.Angles(0, rotation, 0)
				local rotationTween = TweenService:Create(towerToSpawn.PrimaryPart, rotationTweenInfo, {CFrame = TargetCFrame})
#5

I suppose you are using a loop to update the tower’s CFrame, so in this case I would recommend using lerp.

Here’s an example:

local RunService = game:GetService("RunService")

RunService.Heartbeat:Connect(function()
	towerModel.PrimaryPart.CFrame = towerModel.PrimaryPart.CFrame:Lerp(cframe, .1)
end)

And keep the original code:

        elseif input.KeyCode == Enum.KeyCode.R then
			rotation += 90

Oh yeah my bad sry, convert rotation to radians since studio uses it a lot.

local TargetCFrame = towerToSpawn.PrimaryPart.CFrame * CFrame.Angles(0, math.rad(rotation), 0)
local rotationTween = TweenService:Create(towerToSpawn.PrimaryPart, rotationTweenInfo, {CFrame = TargetCFrame})

Asumming the issue is the tower still spins uncontrollably

#7

In the targetcframe variable if i remove math.rad or keep math.rad either way it works but without rotating tween the rotation works as normal but just no tween while rotating

		elseif input.KeyCode == Enum.KeyCode.R then
			local rotationSpeed = 0.01
			local rotationTweenInfo = TweenInfo.new(rotationSpeed, Enum.EasingStyle.Linear, Enum.EasingDirection.InOut) 
			rotation += 90
			if rotation == 90 or 180 or -90 or -180 then
				local TargetCFrame = towerToSpawn.PrimaryPart.CFrame * CFrame.Angles(0, rotation, 0)
				local rotationTween = TweenService:Create(towerToSpawn.PrimaryPart, rotationTweenInfo, {CFrame = TargetCFrame})
				rotationTween:Play()
			end

I also setup a few prints to debug this and it printed rotation tween has played maybe it might be the speed or something in tween info

Edit : even after setting rotation to 10 or 1 it’s the same ; the tower rotates without rotation tween

#8

Are you setting the tower CFrame to equal TargetCFrame somewhere else?

#9

No the variable is only in that code

#10

Your rotationspeed in Tween is 0.01 which means the rotation only takes 10 milliseconds. Have you tried changing that?

#11

I have solved this.
I needed to put the tween in render stepped function of my script
