Apple Pencil, mapping tap gesture to mouse clicks

[cbotman]

Hi there, I was wondering if it's possible to map the Apple Pencil's tap gesture to be "right click"? Currently when using the Pencil as a mouse, the "Tap as click" action is OK*, but "Double tap as right click" doesn't work great as most games seem to pick the double tap as a left click, still.

* "Tap as Click" with the Pencil can cause an issue with Direct Input when you want to hover the mouse over something without actually left-clicking on it.

Perhaps the ideal setup for a "Pencil mode" would be if a single tap on the Pencil was left click, and double tap on the Pencil was right click. Edit: There is no 'single tap' Pencil gesture, but being able to map double-tap on the Pencil to right-click would still be handy.

Would anyone else be interested in this? I'm happy to have a go at implementing it.

Thank you for the commit. I don't have a pencil to test the behavior, but I guess I am going to have to get one. Is pencil 1 usable?
One quick comment is that we should register the pencil interaction in viewDidLoad().

This must be fixed.

If you are referring to the double click of the button on apple pencil, then only 2nd gen can do that. The 1st gen pencil doesn't have a button. 发自我的 iPhone 在 2021-2-3，上午8:56，Chaoji Li <notifications@github.com> 写道：

@SuperKenVery That's unfortunate. I am still on an ipad 6gen:(

OK thanks, I'll resubmit with an update soon. 👍

I will investigate a bit further and open up a separate ticket if I can confirm there is an issue.

I've updated the PR to move pencil registration to viewDidLoad() as suggested.
