Mouse Interaction

[IndieCrypt]

Hello,

I am in need of some help with some coding...

I need to animate my button so that when the mouse is hovering over the button it animates, I just cannot seem to get it to work... I am trying code like

if(mouse_x and mouse_y) = (x and y)

but it is not working... Any help would be great!

You should do it like this:

if mouse_x == x and mouse_y == y

What you wrote translates to:
if both mouse_x and mouse_y are true if and only if both x and y are true,
which isn't what you want.

Thank you!

Actually, now I think of it, it is very hard to get mouse_x and mouse_y to equal an exact position.
To check whether your mouse is hovering over the executing instance, you should do this:

if position_meeting(mouse_x, mouse_y, id)

Also, check out this topic to learn how NOT to use && (and) and || (or):

To check if the mouse is hovering over a specific area use:

xhover = (mouse_x == median(x1,mouse_x,x2))
yhover = (mouse_y == median(y1,mouse_y,y2))

if(xhover&&yhover)
{
    //DO YOUR STUFF
}

That's one way to it, but what's wrong with:

if x1 <= mouse_x && mouse_x <= x2
&& y1 <= mouse_y && mouse_y <= y2 {
    // DO YOUR STUFF
}

Nothing ?
I guess he can use whatever he wants.
