I can't move BasePart with welded parts on TweenService?

I used WeldConstraint on parts with script

That’s intended behavior. You have to either use physics based movement like BodyMovers, or anchor all the BaseParts you want to move, play the tween, and then unanchor them again.

I tried anchored but didn’t work

Did you anchor every BasePart inside the Model? You could maybe also try disabling the welds.

this parts not inside the Model and I anchored every BasePart

I’m not sure if it’s the exact same issue you’re having, but I did post something similar to your topic, and I did find a solution to it.

I hope that helps.

I tried both as a character and from the server.
and I didn’t rotate it, I changed the CFrame to change the position

I want to move the anchored parts together with the tween, but since I don’t want a separate tween for each part, I plan to move them all in the mirror using weld

Tween service is NOT used for physics animations. Tweening only works with anchored parts and guis. Here are some other options:

  1. Use body velocity, force, or gyro
  2. I recommended this: Group the parts together instead of welding it then move it by using :SetPrimaryPartCFrame

I want use TweenService with anchored parts,
thats for just test

and I can’t Tween with anchored parts + WeldConstraint

You’re almost there. You need to anchor the part you’re tweening (partA) and leave the other part unanchored (partB). The WeldConstraint will be the thing that holds up your unanchored part. Let me know how it works out.

bro it worked!!!
1 part anchored true, other parts anchored false and WeldConstraint
I did it!
thank you :smiley:
