RTSE NPC Behavior Designer

NPC Behavior Designer for RTS Engine. Take full control of your NPC AI. NPC Behavior Designer replaces RTS Engine's BasicNPCManager with a powerful, visual behavior tree system that lets you design complex AI strategies without writing code. Visual Behavior Tree Editor: Design AI behavior by dragging and connecting nodes in an intuitive graph editor. No scripting required for common RTS behaviors — just connect conditions to actions and watch your NPCs come alive. Smart Auto-Balancing Nodes: Included Smart nodes automatically handle the hard parts of RTS AI. SmartCreateUnit balances worker vs military production based on current needs, min/max limits, and threat level. SmartBuild prioritizes buildings by need (population > resources > military) and checks affordability. 30+ Ready-to-Use Nodes include Actions (Create units, place buildings, gather resources, attack, defend, patrol, send units), Conditions (Check resources, population, buildings, units, enemy proximity, under-attack status), Composites (Sequence, Selector, Parallel, Random Selector), and Decorators (Cooldown, Repeater, Inverter, Conditional Guard). Parallel Tree Execution: Run separate Economy, Combat, and Main trees simultaneously. Your NPC can gather resources, produce units, and respond to attacks all at the same time. Blackboard System: Nodes communicate through a shared key-value blackboard. Event-driven updates push attack notifications, resource changes, and building completions directly to your trees — no polling required. Runtime Debugger: Watch your behavior trees execute in real-time during Play mode. See which nodes are running, view blackboard values, and track execution history to quickly identify and fix AI issues. Pre-Built Templates: Get started instantly with the included Balanced NPC template — a fully-configured parallel tree handling defense, production, economy, and offense. Customize it to fit your game. Code/Category Filtering: Target specific unit types or building categories without hardcoding. Use the flexible CodeCategoryField to filter by unit code, category, or both. How It Works: 1. Create a Behavior Tree asset. 2. Open the visual editor. 3. Add and connect nodes to define your AI strategy. 4. Assign the tree to the BehaviorTreeNPCManager component on your NPC faction. 5. Remove the existing RTSE NPC components. 6. Press Play — your NPC executes the tree automatically.
