Defining the NPC

Main article: Defining the NPC

To begin the creation of your NPC you must first create a definition for it. The first step is to copy Npc_New.cpp to a new file. Next, make changes to the Precache, Spawn, and Classify functions.

Creating a Condition

Main article: Creating a condition

Conditions show what is going on to the NPC. Are they drowning? Are they blocked? Are they on fire? Conditions tell the NPC to act accordingly to what is happening.

First, create a name for the condition you're making, and add it to the Enum. Once you have added the condition to the Enum, use the DECLARE_CONDITION macro in the AI_BEGIN_CUSTOM_NPC section.
