Hero AI – Gameplay Abilities Meet Behavior Trees
summary
Combines Unreal’s Gameplay Ability System with per-order Behavior Trees and a blackboard-driven three-step order process so heroes auto-prioritize, validate and execute abilities; single shared Behavior Tree handles all ability orders while individual orders keep separate trees for isolation. Uses Gameplay Tags for source/target validation, acquisition radii and distance/health scoring (cleric Heal uses inverse health percent), supports group execution “most suitable unit,” and ships as open source production code; demo shows clerics auto-casting Flame of Life successfully.
