Behavior

Description:
Used to get NPCs to engage in a specific conversation with the player

The procedure completes:
After the actor says the line (and exits dialogue with the player ???)

Parameters

Topic (Topic): Points to the topic that the actor will say
NPCWaitLocation (Location): Where the NPC will wait for the player to enter the TargetTriggerLocation
TargetTriggerLocation (Location): Where the player must be to trigger the actor to start dialogue

The ForceGreet package template handles all the details about getting the actor to walk up to the player, etc.
For a topic with more than 4 lines, testing showed that the ForceGreet procedure does not seem to enter conversation with the player, and acts like a Say procedure where the actor follows the player.
It is recommended that a topic with many lines that is the subject of a ForceGreet procedure is split into multiple topics, with the initial one having few lines and being linked by invisible continuation to the rest.
