Ai goal follow

Entity description

Makes the target NPCs follow another object or the player at a configurable distance.

Limitations and bugs

• NPCs do not intelligently follow their target. They will instead walk or run depending on distance directly towards it.
• If NPCs are following another NPC and that NPC needs to get past them, they will not move out of the way and the leading NPC will eventually give up.
• Keyvalues cannot be changed once the map has been compiled.

Keyvalues

Keyvalues:

Name (targetname) <string>[ Edit ]

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