The Mouse Y block is a Sensing block and a Reporter block. The block holds the mouse-pointer's current Y position, also known as the vertical position of the cursor (relative to the center of the stage).
This block will report -180 or 180 if the mouse is below or above the stage. |
Example Uses
As this block helps report part of the cursor's position on the screen, it is useful for helping the cursor interact with the stage and sprites:
- Creating a virtual slider
when I receive [set price v] repeat until <not <mouse down?>> if <(mouse y) > (100)> then set y to (100) else if <(mouse y) < (0)> then set y to (0) else set y to (mouse y) end end set [price v] to (mouse y) end
- With the Mouse X block, giving the cursor's location
say (join (join (join (join [The mouse is positioned at (] (mouse x))[,])(mouse y))[).])
- Making a grid which objects can snap to
set y to ((round ((mouse y) / (20)))*(20))
- Creating interactive buttons
when gf clicked forever if <mouse down?> then if <<(mouse x) > (50)> and <(mouse x) < (100)>> then if <<(mouse y) > (50)> and <(mouse y) < (100)>> then broadcast (Button clicked! v) end end end
Workaround

This block can be replicated with the following code:
This requires a sprite dedicated to finding the Y position of the mouse. |
forever go to (mouse-pointer v) set [Mouse Y v] to (y position)
