I want to make the surface area of 800x600 but to follow the camera, EG: xview_xview [0], ect ... the surface is drawn in "draw_surface (surface_name, view_xview [0], view_yvieW [0], etc)." The room is 4000x2000 but even if the surface is drawn on the camera are only 800x600 the room ..... HELP!

//Create event
surface_light=surface_create(800,600)
global.light_define=true

//End step

  if global.light_define=true
{
surface_set_target(surface_light)
draw_clear_alpha(0,0)
draw_set_color(c_black)
  for ( i = 0; i < instance_number(obj_block); i += 1 ) 
  {
        object = instance_find(obj_block, i )
        if instance_exists( object ) 
        {
            if position_meeting( object.x, object.y - 32,obj_block) 
            {
                draw_set_alpha(0.6)
                draw_rectangle( object.x, object.y, object.x + 31, view_yview + view_hview, 0 )
                draw_set_alpha(1)

            }
        }
    }
surface_reset_target()
}

//Draw event
draw_surface(surface_light,view_xview[0],view_yview[0])

Can any help me?

surface_set_target(surface)//Set drawin surface
draw_clear_alpha(0,0); //Clear screen errors
with(xdat2_all_parent)//Choose Objects
{

//if not position_meeting(x,y-32,xdat2_all_parent)
draw_sprite_ext(sprite_index,image_index,x,y,image_xscale,image_yscale,image_angle,c_white,1)
draw_sprite_ext(sprite_index,image_index,x,y,image_xscale,image_yscale,image_angle,c_black,.7)
}
surface_reset_target()//restore surface to screen

The 2 sprites are drawn on the transparency of 0.7- Why? First draw it's on 1 and then on 0.7 alpha
I check the surface drawing alpha and image_alpha but dont work!
Please help me! Only happends on Surface!

create event//

//Create by Lester
//Define variables

alpha=0
alpha_temp = 0
for(i=0;i<5;i+=1)
{
if place_meeting(x,y-1-(i*32),obj_block)
{alpha+=2;}
}
//Up alpha
global.render=true

/Draw event

//Check Distance
if global.render=true
{
distance=128
if distance_to_object(instance_nearest(x,y,obj_torch))<distance
   {
   object=instance_nearest(x,y,obj_torch)
   alpha2=distance_to_object(object)/distance
   }
else
    alpha2=1;
    
alpha_temp = alpha
if alpha2 < alpha_temp
   alpha_temp=alpha2

}
