I am trying to make a blank canvas that is bigger than screen. Screen is scrollable. Sizing is fixed. I don't want the canvas to be zoom in/out. I just want it to be draggable. On the screen will be sprites with fixed positions.
I oriented myself with this: https://appinventor.mit.edu/explore/blogs/karen/2018/03.html
When I try AI companion to see if it works there are some issues. When it first opens the upper half of the screen is blank space (which I don't want to be visible) and the bottom half is canvas. When I drag canvas left - right it works. But when I try to drag it up - down it doesn't work. Or the screen scrolls. Then I see space outside of canvas (on the top and the bottom). Which I don't want. Also if I put screen to not scrollable dragging canvas up - down doesn't work.
I included photo of my blocks. Can somebody please tell me what am I doing wrong?
Thank you, Mojca
