Frequently Asked Questions about create-timeline-command

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I add a custom timeline command to the HS2 Sandbox workflow?▼

Adding a custom timeline command requires creating a command class file in Timeline/, registering it in TimelineCommandFactory.cs, and exposing it through a toolbar button in ActionTimeline.cs.

What files need to be modified when creating a new HS2 timeline command?▼

Creating a new HS2 timeline command involves modifying TimelineCommandFactory.cs for factory registration, SubWindows/ActionTimeline.cs for UI integration, and creating a new command class file in the Timeline/ directory.

Does adding a timeline command require manual payload and serialization setup?▼

Adding a timeline command requires payload and serialization setup, but the scaffolding process enforces required payload and serialization conventions along with the necessary IMGUI wiring automatically.

What is the best way to ensure consistent integration when extending the HS2 timeline?▼

The best way to ensure consistent HS2 timeline integration is to use a scaffolding process that enforces required files, factory registration, and UI hooks for every new custom command.

Can I expose a new timeline behavior through the ActionTimeline toolbar?▼

You can expose a new timeline behavior by adding a toolbar button in SubWindows/ActionTimeline.cs, which connects the registered custom command class to the timeline user interface.

Why does my timeline command not appear in the HS2 Sandbox factory?▼

A timeline command fails to appear in the HS2 Sandbox if it is not registered in TimelineCommandFactory.cs, which is a required step alongside creating the command class and wiring the UI button.
