What problem does it solve? Manually verifying gameplay changes in Unreal Engine requires repeatedly launching Play-In-Editor sessions, clicking through UMG menus, and checking actor states by hand. This Skill lets an AI agent run that entire verification loop autonomously against a live editor session. ## Core Features & Use Cases - Autonomous PIE Control: Start and stop Play-In-Editor sessions programmatically, with optional spawn at the current editor camera location. - UI Navigation and Interaction: Extract the live UMG/Slate widget tree as JSON and programmatically click buttons or trigger elements by widget path. - World State Verification: Query actors by class, tag, or radius to confirm gameplay actions (movement, spawning, interaction) actually occurred, and read the message log to catch runtime errors like null pointer accesses. - Use Case: After modifying a main menu Blueprint, ask the agent to launch PIE, click the Start Game button, simulate movement input, verify the player character spawned at the expected location, and confirm the output log contains no errors. ## Quick Start Launch a PIE session, click through the main menu, simulate movement input, and verify the player character spawned without any errors in the log.
