Maybe this will work:

var dir_x, dir_y, i;
dir_x = (keyboard_check(ord("D"))- keyboard_check(ord("A")));
dir_y = (keyboard_check(ord("S"))- keyboard_check(ord("W")));

for (i = 0; i < 4; i += 1;) {
    if !(place_meeting(x + i * dir_x, y + i * dir_y, obj_wall)) {
        x += i * dir_x;
        y += i * dir_y;
    }
}

I don't think that will work because you are multiplying a integer by a boolean.

 

In GameMaker it does not make a difference.

 

Can you explain how that doesn't make a difference?

        y += i * dir_y;
    }
}
