rigid body jittering when another Rigidbody is on it

[misterjuly]

Hello,

I have a rigid body 2d set to dynamic, collision detection continuous and interpolate set to interpolate. This is on a platform that moves downwards. Then I have the player standing on it. When the player is not standing on it it is fine, but if the player is on it, the platform will jitter. How do I get vertically moving platforms that have another rigid body on top of it to not jitter? Thanks!

Hi.
you need to parent player to moving platforms when they are on the platform

[misterjuly]

I tried that. Didn't work. Any other ideas? Thanks!

Hi.
Maybe you need to set a physical material on it?

why do you need a rigidbody on the moving platforms?
How are you moving the platform

[misterjuly]

On some platforms, it is just a rigid body moving it down on others I'm using tween position. I'm honestly not sure if I need the rigid body; I feel like I needed it for some reason, but I don't remember for sure. Physics material didn't seem to work. Any other ideas? Thanks!

Hi.
With Tween position, try changing the update type.
also try removing the rigidbody

[misterjuly]

Tried that as well. No luck. I noticed that it only jitters when I'm on top of it. No other time. I tried it with both parenting, removing the rigid body, and changing the update type. Not sure if that helps...

Thanks!

This might help?

I've watched that video in the past and am currently applying what it says to do in this game. Any other ideas? Thanks for trying though!

I also noticed when I set the platform's rigid body to 0, if I'm standing on it, it still falls (it stays still if I'm off of it). Not sure if this is a separate problem or related (and yes, freezing the platform is something you can do in the game). Thanks!

I think the main issues might be that it has a rigidbody and / or update type of the tweens.

can you show in a video what the jitter is

[misterjuly]

Sorry, been busy with my real job. I will try to post it as soon as I get a free moment.

Hi.
Try setting interpolate to none on the player rigidbody while on the moving platform.

[misterjuly]

Didn't work. I think (but don't know for sure) that it might have something to do with the camera being parented to the player. There are other situations where things appear jittery (example, rotating the camera 180 degrees). In this case the player is jittery when moving and jumping. Not sure if this is related, but thought I'd mention it. And sorry, no time to upload a video yet. Will try to do that soon. Thanks!
