Tension value isn't snapped while dragging #61

Is that a problem?

ariel-phet commented 10 years ago

I am not bothered by it not snapping while dragging, but why does it only snap to "low" "high" and "in the "middle"...MD's original sim had several discrete values to which we could snap, seems like we should match that behavior?

jonathanolson commented 10 years ago

From the design doc, written by MD:

2) Reduce range of tension slider to 3 positions: Lo Med Hi. These three positions are positions 8,9, and 10 on the current tension slider. The reason for restricting tension to the 3 highest values is to prevent aliasing when frequency is high and tension is low

Ah....sounds good. Closing
