-== NPC behavior ==
-=== Navigation ===
-NPCs are able to open unlocked <code>prop_door_rotating</code> entities, if their programming permits it. The process is automated and requires only that a valid [[nodegraph]] link travel through the doorframe.
-=== Combat ===
-Valve's AI does not yet contain any door-specific combat code. NPCs will stand in doorways when others from their squad attempt to pass through, and do not understand the principle of clearing a room from a door entry. For these reasons, combat in or around doorways should be either avoided, or semi-scripted with [[assaults]].
-It is quite possible to have NPCs enter a combat area through a door, but without custom AI code the door itself should not be a point of interaction.
-=== Optimal node pattern ===
-[[Image:Door nodepattern.png|center|Optimal node pattern for a doorway]]
-;Main movement targets
-:Guarantee a nodegraph link by presenting a straight line through the doorframe.
-:Placed slightly ahead to decrease the likelihood of NPCs stopping too close to the door and causing congestion.
-;Flank nodes
-:Create alternate exit points, and are a solid choice for FIND_COVER routines.
-;Entrance / Exit Pinch
-:<code>[[info_node_hint]]</code> of type <code>Entrance / Exit Pinch</code>.
-:Ensures that NPCs travelling through the doorway do so one at a time.
-:'''Limitation:''' NPCs that are not using the node (i.e. are not travelling through the door) may still choose to stand on it! This is a bug that should be fixed.
