Unreal Actor Operations

Version: 2.0.2 Last Updated: 2026-09-08 Dependencies: Unreal Engine 5.8+, UE 5.8 native MCP (HTTP, port 8000), VibeUE plugin (optional) Context7 Validation: ACTOR_API_VALIDATION_REPORT.md (18/20 APIs validated)

Preflight first (2026-09-08): before the first build step of any approved plan, run the unreal-project-preflight skill (ue_preflight.py --live --features <list> --plan-block) so plugins and project settings this skill depends on are enabled in ONE restart. Mid-task "class not found / plugin not enabled" errors go back to that Step 0, never to a runtime toggle.

CRITICAL: MCP Connection Required

BEFORE any actor operations:

1. Verify UE editor is open with project loaded (MCP server runs inside the editor)
2. Native MCP auto-starts on port 8000 when bAutoStartServer=True in project config
3. All Python execution happens on game thread (synchronous)
