The primary entities of a HL1 scanner are listed below. A complete tutorial (which is the source of the listed information) can be found [http://collective.valve-erc.com/index.php?doc=1047433496-46754900 here]
* The player triggers (via a {{ent|trigger_once}}) the whole sequence
* The barney walks over to the scanner performs his "retina" animation ({{ent|scripted_sequence}})
* The scanner model (a {{ent|func_button}}) is activated so it flashes
* Some sounds ({{ent|ambient_generic}}) are played to show that the scanner is operating
* The door ({{ent|func_door}}) is triggered to open

=={{Half-Life 2|4}}==
* [[npc_kleiner|Dr. Kleiner]] walks over to the picture frame (a {{ent|prop_dynamic}} parented to a {{ent|func_rot_button}}) using a <code>scripted_sequence</code>. As Kleiner plays his picture frame animation, the picture rotates into place.
*The button triggers a <code>func_door</code> to open up and reveal the scanner (a <code>prop_dynamic</code>)
*The scanner gets pushed out by an invisible {{ent|func_door_rotating}} beneath it.
*Kleiner walks over to the scanner using another scripted sequence and starts his eyescanner animation.
*The prop_dynamic scanner model changes its appearance using a {{ent|material_modify_control}} entity.
*Several <code>ambient_generic</code> entities play eyescanner sounds.
*After a period of time, a <code>func_door</code> is triggered to open, allowing the player to walk through.
