Scripts to simplify movement

[Vincent]

So I am currently trying to use scripts to make the movement, but I don't know hy this idea I had isn't working.
This is the script:

global.axis = global.axis + global.distance

This is the object's Step event:

if keyboard_check_pressed (ord ("W"))
    {
    global.axis = y
    global.distance = (-10)
    movement ()
    }

Any idea why this isn't working?
Thanks!

Because changing the global variable isn't going to do anything without reassigning it to the object's Y.

if keyboard_check_pressed (ord ("W"))
    {
    global.axis = y
    global.distance = (-10)
    movement ()
    y = global.axis
    }

or you could just do

if keyboard_check_pressed (ord ("W"))
    {
        y -= 10 //or y = y - 10
    }

since x/y are instance-level variables that hold the object's current x/y positions
