Basic overview of agent

Basic Overview

Map Configuration

Make sure any agents placed in your map are set to inactive. Activating them later via map script ensures that the agent can register itself with AgentBlackboard.

TODO

Scripting Setup

TODO

Modes vs Commands

Each mode contains a subset of behaviors. They define what the 'default' action for the agent should be and can be used to give different agents of the same type unique behaviors.

A command is an order issued to the agent independent of the current mode. They can be used to override the agents current action.

Unlike previous HPL titles, agents should only be commanded through modes (or commands) and NOT through changing the agent state.

General Functions

Ghoul_Mode_Set

void Ghoul_Mode_Set(const tString &in asAgentName, eGhoulMode aMode, bool abForce = false)

Puts the ghoul into a mode, which determines its behavior when it's not reacting to the player's presence.

Parameters

asAgentName (tString) — Name of the agent.
aMode (tString) — Which mode to put the ghoul in.
abForce (bool) — If true the ghoul will switch the behavior instantly regardless of state, otherwise it will do so more naturally on the next best opportunity.

Returns:

void
