Add an event
Tap ＋ Add event at the bottom (or ＋ at the top).
Choose System or Input for general conditions, or an object from the scene (or a #tag). Objects show how many instances they have.
Conditions are grouped by category, with a short hint on each. Type in Search to find one. ⚡ marks triggers.
The top line previews the event as it will read. Fill in each field, then tap ✓ Add condition (or ✓ Add action). ‹ goes back to choose a different one.
Add actions the same way with Add action under the event.
