how can use view function for use in the object surface.

for example : monitoring in the security room.

In Lite-C it's something like this:

Code:

---

ENTITY* myObject;

VIEW* side_view = // the view
{
     layer = 30; // above or below others
     pos_x = 0; // position of the view
     pos_y = 0; // position of the view
     size_x = 300; // size of the view
     size_y = 300; // size of the view
     flags = (TRANSLUCENT | VISIBLE);
}

void TheCamera()
{
	while(1)
	{
		side_view.x = myObject.x-100; // behind the player
		side_view.y = myObject.y; // center
		side_view.z = 50; // above the player
		side_view.alpha = 75; // make view transparent
		wait(1);
	}
}

void main()
{
level_load("");
wait(1);
myObject = ent_create ("myObject.mdl", vector(-150, 0, 27), NULL); // create the object in our world
TheCamera(); // start the camera and follow myObject
}

Just search in the GameStudio bible for the words VIEW and CAMERA. Also read the AUM's, George made some security cams in the past.

I think that you´re looking for something like this:
(but this example changes the whole texture)
Code:

---

VIEW* side_view = // the view
{
     layer = -1; // above or below others
     pos_x = 0; // position of the view
     pos_y = 0; // position of the view
     size_x = 512; // size of the view
     size_y = 512; // size of the view
     flags = (VISIBLE);
}

void TheCamera(ENTITY* ent)
{
my = ent;
side_view.bmap = bmap_for_entity(my,0); //render the view into the entities texture

//do something with the view
}

void main()
{
level_load("");
wait(1);
you = ent_create ("myObject.mdl", vector(-150, 0, 27), NULL); // create the object in our world
TheCamera(you); // start the camera and follow myObject
}

very thank's i test it
