Behaviour trees are data structures where nodes of the tree represent condition checks and actions of an in-game entity (typically agent-based). They are widely used in the creation of hand-coded game AI. Complex behaviours can be built by arranging simple control flow and action nodes in a tree structure, which is traversed depth first to determine which actions to execute. The behaviour tree provides flexibility as it lends itself to a hierarchical structure, where behaviour trees corresponding to simple behaviours can be used as sub-trees in a larger behaviour tree that implements a more comprehensive higher level behaviour.

Sir Seddik Khemaissia thank you for your reply, yes I'm about to study the paper you mentioned where I found that new ticking concept (per_node) and I have many questions about the technical implementation of it. I know all about the Behaviours Trees and the conventional traversing method published before, otherwise, I don't really understand this new one where -in my opinion- not really explained on the paper. if we could discuss it here, it would be very innovative.

Hi,

Can you share a link to the paper you mentioned in the question (per-node approach)? I might be able to help.

Hello, yes for sure,
