info_node_link_controller is a point entity available in all Source games except Left 4 Dead series. It controls all connections between navigation nodes that intersect a certain volume. This allows for mass enabling/disabling of node connections.

Keyvalues

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).

Mins (mins) <vector>

Coordinates relative to the entity defining one point of the volume. A box will appear in hammer to help visualize the dimensions of the volume.

Maxs (maxs) <vector>

Coordinates relative to the entity defining the second point of the volume. A box will appear in hammer to help visualize the dimensions of the volume.

Initial State (initialstate) <choices>

State of the node links the moment the map loads. If there is something blocking the NPC's path while this is on, the NPC may appear to walk straight into that object/hole.

• 0 : Off
• 1 : On

Use Larger Radius (for air links) (useairlinkradius) <boolean>

Allow Pass When Off (AllowUse) <string>

Entity or class to allow passage even when node is off.

Invert exclusion rules (InvertAllow) <boolean>

Makes target(s) defined in Allow Pass When Off the only targets NOT allowed to pass when off.

Inputs

Turn links on.

TurnOff

Turn links off.

SetAllowed <string>

Change Allow Pass When Off.

SetInvert <integer>

Change Invert exclusion rules.
