Visual AI Tree Builder for ECS Games
Create a visual behavior authoring tool that lets developers design decision trees or behavior trees and compile them into ECS-friendly runtime systems. The value is faster AI iteration with reusable logic blocks, debugging, and scalable execution.
Why this matters
You want your enemies to do more than chase the player, but every improvement in behavior makes the system harder to maintain and harder to optimize. Reusing logic across enemy types sounds simple until your tree structure becomes fragmented, opaque, and tightly coupled to custom runtime code. If you are working in an ECS architecture, the gap gets wider because most visual AI tools are not designed for data-oriented execution. You need a way to author smarter agents visually while still generating runtime structures that scale under real gameplay loads.
- · Built for Solo and small-studio developers building action games who want more complex NPC behavior without writing and maintaining a full custom AI framework..
- · Most likely monetization: One-time.

MVP Scope · 1–2 weeks
- Design a lightweight visual node editor for decision trees
- Support core node types such as conditions, actions, selectors, and sequences
- Implement reusable subtree templates for shared NPC logic
- Generate a simplified ECS-friendly JSON or C# representation from the graph
- Create a sample enemy behavior pack with two archetypes
- Add an in-editor debugger showing current branch execution per NPC archetype
- Measure and display estimated runtime cost for each subtree
- Integrate graph versioning and export for source control
- Build a Unity demo scene with 100-500 NPCs using generated behaviors
- Open a private beta with guided feedback forms
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Developers may prefer fully custom AI logic for control and optimization, reducing adoption of generated systems.
- 2If generated ECS code is not clearly performant, credibility will drop quickly among technical buyers.
- 3The market may see this as a nice-to-have editor extension rather than a must-pay production tool.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion repeatedly returned to how NPC decisions were authored and whether behavior was sophisticated or simplistic. The developer explained using decision trees that become systems and organizing repeated logic into shared subtrees. That points to demand for a visual authoring layer built specifically for scalable ECS execution rather than traditional AI graphs.
