Closed phet-steele closed 7 years ago
While I didn't see any students do the crazy clicking during interviews, I did see them try to drop terms in the collection box and they would pop out and overlap so perfectly it might have caused a moment of confusion.
I have fixed the primary issue described, but I didn't address the overlap problem mentioned by @amanda-phet in the comment immediately above. Assigning to @amanda-phet - if she thinks that the overlap is an problem, a separate GitHub issue should be logged. After that, this issue should be unassigned and I'll put it on the list to get verified during the next round of testing.
I can't think of a great fix for the overlap issue, and it wasn't a huge problem in interviews, so I will not open another github issue.
Primary issue fixed, closing.
Start by putting two terms directly on top of each other. This is easiest in a game level:
This IS possible on the other three screens and requires combining terms in a corner of the screen (to ensure two terms are on top of each other). By dragging past the corner of the screen, the term you are dragging will be confined to the sim bounds and be placed at a specific location.
Everything in this issue happens to both coins and variables, and to terms with a preset combined count.
Procedure in game (I clicked a lot and edited most of the clicking out):
