Does Box3D support multiple worlds?

[Ronniko]

I want created three personages in my game.
And i thinked created three worlds. Each world for each personage.

b3WorldId worldId1 = b3CreateWorld(&worldDef);
b3WorldId worldId2 = b3CreateWorld(&worldDef);
b3WorldId worldId3 = b3CreateWorld(&worldDef);

I want run physics parallel in three worlds.

float timeStep = 1.0f / 60.0f; int subStepCount = 4;
b3World_Step(worldId1, timeStep, subStepCount);//CPU thread1
b3World_Step(worldId2, timeStep, subStepCount);//CPU thread2
b3World_Step(worldId3, timeStep, subStepCount);//CPU thread3

Because each personage do somthing in here location.
Let`s say: he cuts down trees. Or blows up some territories on terrain.

And sometimes personage might can go to world1 or world2 or world3.

Yes. See B3_MAX_WORLDS. Default is 128. 64k is the hard max.
