Better responsiveness for nipplejs #14
Description
NippleJS allows for on the fly joy sticks. A naive listener is implemented for PWA clients on mobile, but the experience is janky.
The listener only fires when the joystick changes. Thus holding the joy stick to the left does not fire more events to the left. In addition, when first moving the joy stick to the left, many events are fired in quick succession- giving a pretty broken feel.
1. A solution for this would be to check if left is active, and then call a listener every n steps.
2. Alternatively, allow for a client registering a listener exclusively for the joy stick. That way behavior can be handled client side.
