RAIN AI
Rival Theory's RAIN AI
is a very full-featured AI to use and it is free. It includes a
behavior tree with similar functionality to React, but has more features built in. In fact,
this one won't require any additional scripting to go from point A to point B.
To get this going, we'll need the following bases:
• A map to move around on
• A character to move around in the map
• A route (series of waypoints) for the character to follow
• A navigation mesh that knows what to avoid
• An AI to control the character
• A behavior tree to tell the AI what to do
To start with, you'll need to start a new Unity project, import Unity's Character Control-
ler, and import the RAIN AI package.
