Unreal Unreal Common UI Reference

Purpose

Common UI activatable widgets, input routing, platform prompts, and menu-stack behavior.

Guidance

• Select this reference only when the task names or clearly implies Common.
• Identify package/plugin version, project files changed, and validation evidence.
• Avoid making this plugin mandatory for unrelated lightweight prototype work.

Validation

• Prefer project-local engine commands and Codex Game Studio project validation before readiness claims.
• Record unknown version-specific behavior as a risk instead of presenting it as confirmed.
• Keep this reference selected by relevance; do not load every engine reference for one task.
