Body position too elastic

[nidbahn]

@steven4547466

If you increase dampening (BodyPosition.D), you can get rid of this effect, but it’ll slow down as it reaches its target.

There’s also a risk that it won’t reach it’s target precisely and stop before it

@steven4547466

Alternatively, you could also use tweening if you don’t want to deal with body movers.

This wouldn’t move players standing inside, which is one of OP’s requirements I assume.

Small problem, because the train isn’t anchored, it now falls to the ground, but I want it to stay floating like it is on the body position version.

[nidbahn]

Have you tried increasing the MaxForce?

Not by default but that can also be scripted, and has been done before as well:

Moving parts with Tween Service does NOT move the player physically

Hello everyone. I have a problem with using tween service to move other parts physically. I used Tween Service to move a train model so it can move players from a station to another (look in “Example 1”), but I realize that once a player jumps off of the seat or just don’t use the seat at all, the tween will ignore the fraction between the player and the floor (look in “Example 2”) I’m trying to make the player move with the train, as 1 part, (look in “Example 3”)

So far, I’ve only added the actual attachments. I’m not too sure which values I need. Could you tell me?

[nidbahn]

Create an AlignPosition constraint. The Attachment0 property should point to the attachment on the train, while the Attachment1 should point to the attachment on the starting part.

MaxForce: Make it really high, but not too high because it will fling itself into void
MaxVelocity: Set it according to your preferences
Responsiveness: Same as above

Example setup:
(I also used an AlignOrientation to keep the Train part upright)

[Towren (Tow)]

Yeah, so, that doesn’t work. The train just flies up.

Here’s a video of what happened Video_27

[nidbahn]

Looks like you didn’t do anything to keep it in correct orientation. I wonder why the same didn’t happen with your BodyPosition example.

Try using an AlignOrientation constraint. Set attachments the same way as in AlignPosition and enable RigidityEnabled.

[Towren (Tow)]

Works amazingly! However, when someone sits in a seat in the train, the train starts to jerk all over the place.

[nidbahn]

Can you record a video of that?

[Towren (Tow)]

I have no idea why it does this Shaky

[nidbahn]

When you sit, the train temporarily rotates in the direction your character was going. This suggests that the mass of the train is lower than your character’s mass, which is not good.

@flapjakes

Maybe you could make the parts on the train massless.

Did you try this solution and leave it like that? Make sure all parts have the Massless property disabled.

[Towren (Tow)]

Oh, I’d better disable massless then
