We’re working on a new multiplayer version of our game 99 Bricks (previously on mobile as 99 Bricks Wizard Academy). We’ve just switched from Unity 4.3 to Unity 5.1 and we’re encountering very strange physics behavior. When we’re building a tower, the bricks seem to be pushed outwards. I’ve included 2 videos of our auto builder tester, one in Unity 4.3 and the other in Unity 5.1. As you can see, the 4.3 is quite stable, but in 5.1 the bricks start sliding immediately and the tower collapses.
We’re using the 3d physics in both versions, we’ve tried adjusting all possible physics settings and materials, but nothing helps (including “Enable Adaptive Force”).
We have tried converting to 2d physics in unity 5.1 and that works as expected (no strange behavior), but the reason we used 3d physics in the past was that it gave the game a better gameplay feeling, so we would like to keep the 3d physics option open.
Is this is a known issue or expected behavior inUnity 5.1. Is there something we can do or is 2d physics the only way forward?
Joram - you’re welcome to file this bug as any other one really - just use the built-in bug reporter tool right the Editor help menu. But please do let me know the case# so that I could dig it up in the stream of incoming bugs and investigate faster. Thanks.
