I need help with model tweening!

[tomatofarmer_444 (Tomato)]

I need help.
so a while back i made an module for tweening models and published it just now, but i got comments about the code being deprecated. i have no idea how to make it better with the new api stuff and all info i’ve searched up is old or does not answer my question.

So… is there any way i can tween models on the server side using cframes and so i dont need to weld all the models?

I would recommend welding all the parts of the model to the model’s primary part and just tween the model’s primary part.

EXAMPLE:

local ModelPP = workspace.Model.PrimaryPart

local TInfo2 = TweenInfo.new(3, Enum.EasingStyle.Linear, Enum.EasingDirection.In)

TweenService:Create(ModelPP, TInfo2, {Orientation = ModelPP.Orientation + Vector3.new(0,0,10)}):Play()

You can create a CFrame value, and do a .changed event on the CFrame value and then tween the value… Sorry if that is confusing, not sure how to explain it well, but here’s an example:

local model = workspace.Model
local cframeValue = Instance.new("CFrameValue", workspace)

cframeValue.Changed:connect(function()
    model:PivotTo(cframeValue.Value)
end)

game:GetService("TweenService"):Create(cframeValue, TweenInfo.new(0.5), {Value = Your_CFrame_Here}):Play()

There is actually a really good resource already out there for your situation:

Introduction to Tweening Models

Edit (06/30/2021): Due to the release of the new pivot APIs and the thankful deprecation of SetPrimaryPartCFrame, the legacy method of CFraming is now also appropriate and you do not necessarily need to use this welding method. Do note that the pivot CFrame is different from the PrimaryPart CFrame though, so you will have to account for that when writing your proxy objects. Edit (05/31/2023): Roblox has an official code sample for model tweening! It’s very lightweight and covers the necessities…

@tomatofarmer_444

using cframes and so i dont need to weld all the models?

i need it to be anchored and i dont like welding models together.

i did not understand it.

Try welding all descendants to the Model’s PrimaryPart and tweening the PrimaryPart.

already answered.

i guess i can make an auto welding system but idk. ill try to find a way to move models via cframes (also that the model is anchored)

^^^^

Depending on what you’re doing, you could anchor it and script so before the tween starts, the model unanchors and then anchors again when the tween ended

[tomatofarmer_444 (Tomato)]

yea i could try to do that. good idea.

Alright, if it works, please mark the solution to your post

To tween models, they need to be welded to the PrimaryPart and be unanchored (except for the PrimaryPart)
