unavailable3DReason property

String? get unavailable3DReason

Why create3D would throw here, or null when 3-D physics can run.

Finding out starts Jolt where it can run, with the default job system (cores minus one threads): call create3D first when the thread count matters.

Implementation

static String? get unavailable3DReason =>
    JoltPhysicsEngine().unavailableReason;
