How do I check if the engine is running? Where's engine.enabled flag? Runner can't be stopped? Or always reporting 'enabled === true'?

The following illustrates and documents problems I am experiencing:

this.engine = Engine.create()
...
		let runner = Runner.create()
		Runner.run(runner,this.engine) // even if commented out...
		Runner.stop(runner) // even if commented out...
		console.log(runner.enabled) // ...true, true, still true, always true...
		console.log(this.engine.enabled) // undefined Why? How do I check if the engine is running?
		console.log(runner)
		runner.enabled = false
		console.log(runner.enabled) // now it's false, but has it really stopped (and stopped the engine too)?

Basically, I am writing unit tests for my app, and I need to know that the engine is running at a given point in the app's execution.

There's nothing built in to track this, the runner.enabled property is just used for pausing during running, so it will always be true unless you set it to false to pause. You'll have to track it yourself for now, but I'll add this as a feature request.

Lovely! Thank you so much liabru!
BTW. Looking forward to those cued PR to be merged into the next ver. of Matter.js.
Looks to me like many of them will give it a nice performance boost.
Currently, even about 100 bodies bouncing around make a slightly aged mobile to stutter.
cheers

There is no more in .
To pause/resume simulation I am using Runner.stop() and Runner.start(). But, according to the documentation, I should be using engine.enabled property. However, it is undefined in 0.14.2 and in 0.10 too.

Oh my bad, I actually meant to say runner.enabled, try that instead.
