Issue
The rotating / motor bolt is a type of motor in LittleBigPlanet 2 that allows one item to spin relative to another. This motor does not spin in RPCS3. Elastic is a type of strut that makes one object have a stretchy attachment to another, in RPCS3 the elastic does not stretch but rather gets stuck at a distance and no longer moves. The spring is another strut that instead makes an object bouncy (like a trampoline) when it is suppressed by a weight on top of it, this also doesn't work and instead suppresses and then doesn't bounce back again.

These are used everywhere throughout the story mode and can be vital to your progression in some levels. By not working correctly, some machines and contraptions are completely broken. One example is the story level "Currant Affairs" where a platform is attached to a spring and is used to gain momentum and height to jump over an obstacle. This platform does not move at all.

Motor bolt

Spring

Elastic

These issues aside, LBP2 is performing very well, rarely crashes and has only a few visual bugs that are non-intrusive. The game could easily be pushed into "Playable" if these were to be fixed and I imagine they could possibly all be related to a single physics issue rather than individual problems.

XFloat off did it - had LLVM on before, don't worry.

Beautiful - finally aced the level too haha.

Well, looks like I know what I'm doing for the rest of the day- time to test the game from beginning to end. Good job mate.

This Part of a Larger Issue with the Physics in the main ps3 games. This is Especially Egregious in Story Levels in LittleBigPlanet 1. As You Can't Finish the 3rd level in LBP1 because it relies on the physics to move the checkpoint over a Fallen bridge as part of a tutorial.

Yeah I gathered it was an issue with physics in general. Hopefully this and the log I've attached can help solve this issue though and actually improving the accuracy/speed of the emulator in general. Who knows, fixing this could sort out several problems with other games too.

I come to update this thread. I made a level to test the 10 types of junction with 4 units of each, I recorded a video and a log. Xfloat and spu fast make no difference.

Retest this with https://ci.appveyor.com/api/buildjobs/pe9poxs8twn8nig3/artifacts/rpcs3-v0.0.8-6fb3307a_win64.7z (elad's fix preview). It may be fixed by #7532.

Wasn't a complete fix, definitely feels like there's an improvement though. Pistons are still broken in many areas.

After I heard LBP1 was playable I decided to try out this game as well. As far as this specific issue goes all "tools" (Motor bolt, Spring, Elastic) that were a problem now work properly and the level in question "Currant Affairs" is able to be completed. I recorded a short video to demonstrate and I feel like this issue can be closed. I actually had quite a bit of an issue with the level "Brainy Cakes" due to the hazardous gas not despawning on a specific puzzle but I would have to investigate further and was able to bypass it with a little luck.

Same, this was fixed for me after #7565. It should be retested.

can you tell me how you got past the Brainy Cakes level? im stuck on it right now and i kinda got a thing going by throwing the cakes at the wheel to make it spin ever so very slightly but one, its not enough force to make it spin over and two, the jelly wall is still a constant effect

Not fixed on BCES01086.

Currant Affairs is my go-to level to check. As it currently stands, you can reach the end but the final door leading to the scoreboard doesn't open.

Recently, there's a piston at the very start of the level above a chicken and that now falls to the ground. About midway through the level there's sackbots being shaken around and behind them is a mechanical system with pistons - the system goes crazy and the things the pistons are attached to are flailing around wildly.
