ai_goal_actbusy_queue is a point entity present in some Source games. It can do anything that an ai_goal_actbusy can do, except this entity is designed to order actbusy hints and NPCs in a queue. The queue can be moved forward, and when the first NPC in the queue leaves, it can be given orders. This entity was used for lines in d1_trainstation_01 and 02.

Keyvalues

Exit Node (node_exit) <target_destination>

An info_target the NPC at the front of the queue should head to when leaving. This MUST be specified.

Node 1 (node01) to Node 20 (node20) <target_destination>

Used for defining the path of the queue, with info_node_hints. Node 1 is the front of the queue. The number of defined nodes defines the maximum number of NPCs queuing.

Must Reach Front (mustreachfront) <boolean>

If true, an NPC must strictly be at Node 1 before being able to leave the queue.

Inputs

MoveQueueUp

Moves all NPCs in the queue up one position, and sends the front NPC to the Exit Node.

PlayerStartedBlocking <integer>

Tell the queue manager that the player has started blocking a specified point in the queue.

PlayerStoppedBlocking <integer>

Tell the queue manager that the player has stopped blocking a specified point in the queue.

Outputs

Fired when the queue moves up. Automatically puts the number of NPCs remaining in the queue as the input parameter, unless overridden by the mapper.

OnNPCLeftQueue <string>

Fired when an NPC begins going to the Exit Node. Automatically puts the targetname of the NPC as the input parameter, unless overridden by the mapper.

OnNPCStartedLeavingQueue <string>

Fired when an NPC is at Node 1. Automatically puts the targetname of the NPC as the input parameter, unless overridden by the mapper.
