Unclear what the result should be when adjusting amplitudes using multitouch #81

Test device iPad Air 2

Operating System 15.1

Problem description https://github.com/phetsims/qa/issues/733

This is related to https://github.com/phetsims/normal-modes/issues/79 When using multitouch to adjust amplitudes, I was unsure whether the values displayed were correct.

Steps to reproduce

  1. On the 1 dimension screen, use one finger to hold a mass in place while increasing the values of all amplitudes using the sliders.
  2. Let go of the mass--the amplitude values change.

The multitouch problem is tracked in https://github.com/phetsims/normal-modes/issues/79. It will not be addressed for the prototype, and longterm multitouch requirements need to be specificed in and https://github.com/phetsims/normal-modes/issues/80. For example, what is the desired behavior when dragging a mass and changing its amplitude slider? I have no idea - it's unclear to me too!

@arouinfar As long as the sim does not crash, I recommend closing this as "won't fix".

Nice find @Nancy-Salpepi. I agree with @pixelzoom that multitouch is beyond the scope of the prototype. Closing as won't fix.
