what is the meaning of" bridge.loop(0,1,12,13)"

bridge.check() pls help in easy vr programming

Sounds like a class method or property, perhaps from a library. Let me put on my telepathic hat and see if I can read your mind...

Nope... could you clarify your question? Perhaps tell us what you are trying to do, show us some source code?

The variable bridge is an object which has a method called loop. The code calls that method with four numeric arguments.
