I don't know anything about behavior development.
I need to create a copy of the default physics behavior with my own settings (just lowering b2_velocityThreshold actually)
What's the difference between runtime.js and runtime-ams.js in this directory? The behavior seems not to be using runtime.js as deleting this file won't cause the behavior to crash.
If I replace runtime-ams.js content with runtime.js content, the behavior seems still working though the file is half the original size.
Can you explain me what's going on here?
What would be the best method in order to make my own copy of this behavior?
