When I call ImageSprite to reach a specified position, if the border of the image touches the Canvas, it will stop and not go beyond. How can I improve this?
Place the canvas inside a vertical arrangement (you should do this anyway to workaround a canvas bug). Centre the vertical arrangement both ways. Set the canvas width and height to values larger than the vertical arrangement width and height.
Components on the canvas will now seem to disappear off screen, yet still exist (you need to bear this in mind!)
The ExtendMovesOutsideCanvas block exists for legacy reasons, and should have no impact on your canvas components.
I remember the imageSprite created by extension CompCreator can be moved out of canvas, but I am away from computer and can not give an example. You may have a try.
