The Mouse Y block is a Sensing block and a Reporter block. The block holds the mouse-pointer's current Mouse Y.
Example Uses
As this block helps report where the mouse-pointer currently is, it is useful in sensing things with the mouse.
Some common uses for the Mouse Y block:
- Helping to make 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 mouse's location
say (join (join (join (join [Your mouse is positioned at (] (mouse x))[,])(mouse y))[).])
- Making a grid which objects snap to
set x to (([ceiling v] of ((mouse x) / (20)))*(20))
- 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
- Adding animations to the mouse
forever go to [mouse pointer v] change [color v] effect by (2)
