Goal Oriented Action Planning AI Framework

Namely, I was thinking of setting it up so that PerformAction is a BT_Task node that lets you reference an action object, and then using the BT for the FSM, e.g., set up Idle and Move states in the BT, with PerformAction being another BT_Task node.

I’ve never looked into the BT implementation in UE, if it’s possible to re-use an Action class from there I should take a look into it! Thanks.

Another thing is that it seems from your devblog that you’re doing your own pathfind, curious why do that instead of hook into the normal pathfind.

The planner is just a pathfinding algorithm, except instead of finding a path through a navmesh, you’re finding a path through world states…so in the devblogs when I’m talking about pathfinding, I’m talking about the planner I use the standard AIController stuff for moving the AI Agent. The current pathfinding algorithm in the planner is just a simple depth-first. You can use whatever method you want, A* etc.

Edit: This paper is topical to extending BTs with planning systems: http://projekter.aau.dk/projekter/files/52867041/ThesisFinal.pdf

Edit again: The above paper actually implements planning as an extension of the BT using a similar method to the one I propose above. The part of the paper in question is “4.3 Implementation” where it mentions the “Planning Node”.

Thanks, I’ll have a read…
