GameMaker Scaling the interface

[Pedau666]

I'm trying to scale the interface like in the code of score, where text is scaled when window changes its resolution. I have a example code where this works but I can't make this in the health system where are sprites.
Can you guys help?
Here is the good code of the draw event from the score:

draw_set_color(c_white);
draw_set_font(fnt_start);
draw_set_halign(fa_center);

draw_text(camera_get_view_x(view_camera[0]) + (camera_get_view_width(view_camera[0]) * 0.91),
camera_get_view_y(view_camera[0]) + (camera_get_view_height(view_camera[0]) * 0.04), global.points);

draw_set_font(fnt_start2);
draw_set_color(c_silver);

draw_text(camera_get_view_x(view_camera[0]) + (camera_get_view_width(view_camera[0]) * 0.95),
camera_get_view_y(view_camera[0]) + (camera_get_view_height(view_camera[0]) * 0.11), global.coins);

draw_set_color(c_yellow);

draw_text(camera_get_view_x(view_camera[0]) + (camera_get_view_width(view_camera[0]) * 0.85),
camera_get_view_y(view_camera[0]) + (camera_get_view_height(view_camera[0]) * 0.11), global.gold);

draw_set_color(c_white);

And here is draw gui event from health object which causes health to move on the screen when player is moving and doesn't scale at all.

var zwidth = camera_get_view_x(view_camera[0]) ;
var zxx = zwidth;
var zyy = 35;

var zxempty = 0
var zyempty = 0

var zxfull = 0
var zyfull = 0
var zxhalf = 0
var zyhalf = 0

o_player.maxhp = clamp(o_player.maxhp, 6, 40)

o_player.hp = clamp(o_player.hp, 0, o_player.maxhp)

//empty
repeat(o_player.maxhp/2)
{
    if zxempty == 65 * 10
    {
        zyempty = 65
        zxempty = 0
    }
    draw_sprite(s_heart_empty, 0, zxx + zxempty, zyy + zyempty)
    zxempty += 65;
}


//half
repeat(floor(o_player.hp/2) + frac(o_player.hp/2) * 2)
{
    if zxhalf >= 65 * 10
    {
        zyhalf = 65
        zxhalf = 0
    }
    draw_sprite(s_heart_half, 0, zxx + zxhalf, zyy + zyhalf)
    zxhalf += 65;
}


//full
repeat(floor(o_player.hp/2))
{
    if zxfull >= 65 * 10
    {
        zyfull = 65
        zxfull = 0
    }
    draw_sprite(s_heart_full, 0, zxx + zxfull, zyy + zyfull)
    zxfull += 65;
}


if o_player.hp = 0 instance_destroy();
