Interrupted sequence behaving differently first time

[samselikoff]

I'm running into an issue that might be a bug, or a misunderstanding on my part:

The console is a result of me doing the following sequence twice:

1. From rest, click the button (toggling isShowing)
2. Click the button again in the middle of the animation, interrupting it

The first two console.tables show this:

1. Blue box is inserted, Red is removed
2. Red is inserted, Blue is removed

I would have expected (2) to be, Red is kept and Blue is removed.

The second time the sequence is run, that's exactly what I see.

Any idea what's causing this?

Hmm, I agree that is unexpected.

Removed sprites only survive interruption if there is at least one motion using them when the interruption happens. That seems to be the case here, but maybe that's an area to investigate. If something is interfering with the motion or making it stop early, that could cause this.

To clarify:

Step 1       🔺----------------------------
             ----------------------------🔷

         
                👇 removed
Step 2       ---🔺-------------------------
(begin)      -----------------------🔷-----
                                    👆 inserted

                            
                    👇 ?
Step 3       -------🔺---------------------
(interrupt)  -------------------🔷---------
                                👆 ?

if in Step 2, 🔺 is a removedSprite and 🔷 is an insertedSprite, and that animation is interrupted while both sprites are still being animated, what should the categories of 🔺 and 🔷 be in Step 3?

Red goes from removed to kept, blue goes from inserted to removed.
