Welp, here you go

when green flag clicked
forever
if <(mouse x) > [Number that has no -]> then
whatever
end
if < (mouse x) < [Number that has a -]> then
whatever
end
end

same with the Mouse Y

There's a mouse x and mouse y reporter block at the sensing category.

when I receive [detect v]
if <(mouse x) > (0)> then
 right script :: grey stack
else
 left script :: grey stack
end

I hope it helps you.

But it needs to detect if mouse is at the right or left of where it is pointing at.

Both of those scripts do that

Cutie_Pooge

set [myDirection v] to (direction)
point towards [mouse-pointer v]
set [mouseDirection v] to [middle]
if <(direction) > (myDirection)> then
set [mouseDirection v] to [right]
end
if <(direction) < (myDirection)> then
set [mouseDirection v] to [left]
end
point in direction (myDirection)

doesn't work

Oh yeah, that's because scratch direction goes from 0 to 90 to 180 to -90 to 0. I'll try to fix it.

It's to confusing.

Here you go:

when green flag clicked
if <(mouse x) < (y position)> then
left script:: grey
else
right script:: grey
end

It's the easiest way I could find.

I´m not quite sure of understanding you. May be https://scratch.mit.edu/projects/411501837/ ?

That only accounts for when the sprite is at (0, 0). Also, the sprite is a bit off centre and looks weird.

Well, i have not idea if it is at screen´s center, about being off centre, who cares? it is simple to fix.

HepticSupport

when green flag clicked
forever
if <<(mouse x) > (x)>> then
(do whatever)

end
end

define x
set x to (x)

Can you make the line start at the middle?

Cutie_Pooge

Just place the purple dot at the centre, if your project always has the starting at the centre you can just use Oumuamua's script.

Thanks everyone, but I actually figured out how to do it myself.
