Autonomous Exploration
A lightweight reinforcement learning agent roams Unity or Unreal maps, recreating chaotic player behavior across jump, crouch, and wall-hug paths.

Stop walking into walls.
Let autonomous telemetry find your collision leaks.
GhostTester is a Unity and Unreal SDK that turns chaotic NPC movement into actionable collision evidence, before your release build reaches players.

01 / The brief
A small tool for a very specific release-day problem.
# target_user
For teams shipping complex 3D spaces.
Indie developers protecting their sanity during a tight release schedule, plus AA/AAA QA teams that need more coverage than human wall-walking can provide.
// Not a general-purpose test suite.
// A focused collision signal for game teams.
// A focused collision signal for game teams.
# pain_point
Manual coverage misses the weird stuff.
A tester can spend hundreds of hours walking into walls, but cannot recreate every jump, crouch, wall-hug, and high-velocity edge case. One missed breach becomes a Day-1 crash or a costly post-launch patch.

02 / The AI core
A build pipeline for collision evidence.
No magic box. Three observable stages from movement data to a ticket your team can triage.
02 / DETECT[breach_event]
Instant Collision Breach
When transform coordinates cross a solid mesh layer, the engine pauses, captures the physics state, and preserves the exact failing frame.
03 / REPORT-> git_issue
LLM Reasoning & Reporting
Telemetry and a frame snapshot become a structured report with severity, coordinates, collider context, and a production-ready JIRA ticket.
03 / Local engine integration
Install the plugin. Keep the build local.
Seamless Engine Integration
Download our lightweight package, import it into Unity or Unreal in 2 clicks, then attach the GhostTester script to any NPC or autonomous test agent.

Honest limitations
Minor false positives can occur on non-solid visual meshes such as foliage or cloth curtains. The active bounding-box metadata filter bypasses non-blocking layers.
Zero security risks
The SDK operates locally inside engine telemetry. Only lightweight text strings, coordinates, and object names are sent to the LLM API for report generation.
