Built-in variables are of two types: either they are event-reference variables created when an event occurs, or they are static variables available at all times.

Event reference variables can be used in actions to reference event values more flexibly than the #value# reference. Event reference variables are prefixed with "@event_" or "@e_" and are set automatically when the events in the command are evaluated.

• The event reference variables are set according to the first event for each event type.
• You can only use event reference variables in actions; you cannot set or reference them in events.
• You can only use event reference variables in commands where the referenced event is present.

Event reference variables are defined for each event on the Events page.

Static variables are accessible at all times, no matter which event triggers the command.
