Create a new physics world. You should only do this if you want to simulate an extra world for some reason.

Air density of this physics world, for things like air drag.

All bodies in the world

The body of this physics world.

Set or retrieve the collision rules for this Sandbox.PhysicsWorld.

A SceneWorld where debug SceneObjects exist.

Access the world's current gravity.

The physics group of this physics world. A physics world will contain only 1 body.

Physics simulation mode. See Sandbox.PhysicsSimulationMode for explanation of each mode.

If true then bodies will be able to sleep after a period of inactivity

If you're seeing objects go through other objects or you have a low tickrate, you might want to increase the number of physics substeps. This breaks physics steps down into this many substeps. The default is 1 and works pretty good. Be aware that the number of physics ticks per second is going to be tickrate * substeps. So if you're ticking at 90 and you have SubSteps set to 1000 then you're going to do 90,000 steps per second. So be careful here.

Raytrace against this world

Updates all the SceneObjects in the Sandbox.PhysicsWorld.DebugSceneWorld, call once per tick or frame.

Delete this world and all objects inside. Will throw an exception if you try to delete a world that you didn't manually create.

Gets the specific collision rule for a pair of tags.

Like calling PhysicsTraceBuilder.Run, except will re-target this world if it's not already the target

Like calling PhysicsTraceBuilder.RunAll, except will re-target this world if it's not already the target

Used internally to set collision rules from gamemode's project settings. You shouldn't need to call this yourself.

Temp function for creating model physics until entity system handles it

Step simulation of this physics world. You can only do this on physics worlds that you manually create.
