Behavior Trees

Behaviour trees are the standard way to structure game AI: a tree of selectors, sequences and conditions that decides, each tick, what a character should be doing.

The appeal is legibility. Behaviour sits in a structure a designer can read and edit, rather than inside a state machine that grows unmanageable once a character has more than a handful of modes. Branches can be reordered, decorated with conditions, and reused across characters.

Working with them well means designing the tree so that priorities are obvious and a change in one branch does not break another. The hard part is rarely the tree itself but what feeds it: perception, memory of what a character has seen, and a blackboard that holds the facts the branches test against. Debugging usually means watching a live tree while the game runs.

Pathfinding solves how to get somewhere; Behaviour Trees decide whether to go. The skill appears in AI programming and in technical design roles alike.
