Perceptions

Whenever a Character notices (assesses) something in the world around it, a Perception is triggered. For each perception, a script-state can be registered to be started once that perception fires.

Depending on the script-state entered upon assessing something, perceptions may be set up different, ie. Npcs reactions differ depending on their situations.

Perceptions can be manually triggered from script-code (marked ) or are sent from the engine on certain actions (marked ).

Active Perceptions

Here is a list of all perceptions checked by each character individually every frame:

• Assess Player:
  Triggered when the Player is nearby.

• Assess Enemy:
  Triggered when a hostile Character is nearby.

• Assess Fighter:
  Triggered when a nearby Character has their weapon out.
  Sent when someone transformed into a Bloodfly. (?)

• Assess Body:
  Triggered when a nearby Character is dead or unconscious.

• Assess Item:
  Triggered when an item is nearby.

Note

If multiple nearby Characters apply, the perception is only triggered for the closest one.

Passive perceptions are usually broadcast to all nearby applicable Characters within a certain range.

Note

Perception ranges can be adjusted separately from the Daedalus-scripts.
