Pushing on people's fronts #208

Closed phet-steele closed 7 years ago

Present in the deployed version:

  1. Screen 2,3, or 4. Disable friction (if applicable).
  2. Place a person on the stack, with at least one other object below them and not the other person above them.
  3. Apply force toward the right and get the stack moving at an appreciable rate.
  4. Start applying force toward the left.
  5. While the stack is still moving to the right, pick up the person and place them back on the stack. Now, even though force is being applied toward the left, the person on the stack is facing right.

Should be fixed in the above commit, to be verified in the next RC test.

I haven't found a way to reproduce this anymore, thanks @jessegreenberg.
