# Schedulers Every VFX has exactly 1 Scheduler. Schedulers control when Timelines are started, and have 2 components: a list of items, and a list of triggers. A scheduler can have an arbitrary number of items, but must have 12 triggers. Both items and triggers follow the same format: ``` bool Enabled int StartTime int TimelineIndex ``` ## Triggers What the triggers represent is not understood, but they are probably each for a specific type of action, such as sheathing a weapon, getting hit, etc. Unused triggers have `TimelineIndex = -1`. ## Items Items function like triggers, but will start automatically without any additional input. If you are having trouble viewing a VFX, such as one which was originally used for a cutscene, it can often be useful to disable all the triggers, and instead exclusively use items to start timelines. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
