Did we lose Z text from the Graphics & Animation reference page?

Why multiple sprites respond to a single TouchDown event?

Hello, I have two imagesprites in a canvas in a way that the first one (the smaller) overlaps partially with the second one (the larger). I have set z=2 for the smaller and z=1 for the larger, so that the smaller is always drawn on top. Everything fine until this point. However, when I tap on the screen, both sprites respond to the TouchDown event at the same time. I would expect that only the sprite on top would process the event. Also I wonder if the App Inventor engine calls the TouchDown f…

highlighted a gap in the doc page for Sprites and Balls.
While the X and Y values are described well, the Z value explanation leaves out the direction of ascending/descending Z values: towards vs away from the observer.

Also the user had to test for himself to determine Z precedence of stacked TouchDown Events for overlapping Sprites. (Which fires first, Z=1 or Z=3 ?)
That should have been stated.

Thanks for the report @ABG. When we moved to markdown for the documentation some of the detail was lost. I’m working on a patch to address this.

This was fixed in a recent release. The text is now:

Z (number)
How the ImageSprite should be layered relative to other Balls and ImageSprites, with higher-numbered layers in front of lower-numbered layers.
