I’m building a swing using rope constraints. As you can see in the attached video, the swing on the left does not respect the physics when the character is standing on the moving part, the character does not move with the part. The swing on the right works perfectly fine.
The difference between the 2 swings is that the one on the left uses only 2 attachments at the top and 4 at the bottom. The one on the right uses 4 at the top and 4 at the bottom.
I was able to reproduce this, it’s because the swinging part is too thin. I’d recommend welding a thicker invisible part to the underside of the swinging part. It’s weird that it doesn’t work for parts that are too thin though.
After some testing, it seems like the thickness must be greater than 0.55 studs for the character to platform stick to a platform.
I deleted all the attachments and the rope constraints. Made the part extremely thick. Added in the new attachments and rope constraints. Still having the same problem.
Now one other difference is that I use a cylindrical part for the anchor at the top as opposed to a block, but I don’t think that should matter.
