Help Request: how can i use this lib for a 2D game?

[pheonixfirewingz]

I'm working on a 2D game that requires heavy physical hot can I use Jolt to achieve it

[jrouwe]

That's a very broad question. I would start by looking at the samples:

https://github.com/jrouwe/JoltPhysics/blob/master/Samples/Tests/General/TwoDFunnelTest.cpp

[pheonixfirewingz]

It’s a pure 2D game that doesn’t have a “Z” axis I wanted to find out how to use jolt when I don’t have a Z axis in play

[jrouwe]

You would just specify 0 for the Z axis. Jolt's vectors are always 3D, even if you're not using the Z coordinate. The line bcs.mAllowedDOFs = EAllowedDOFs::Plane2D; ensures that all bodies stay at Z = 0.

Hay I’m stuck at a point where i need to sync the jolt physics to the scripting & rendering engine how can i get and set the position and rotate pre & post jolt updates. I couldn’t find where there was an example of this.

Use BodyInterface::GetPositionAndRotation on e.g. PhysicsSystem::GetActiveBodies
