Event sheets and groups
If we wanted to make a different level for our platformer game, we would need to copy-and-paste all of the events into the new layout. With Event sheets, the same events can be re-used across many different layouts. This is also useful for separating different sheets of events, as more than one event sheet can be imported in a single layout.
Inside an event sheet, we can also use Groups. These are able to separate events and can also be activated, or deactivated, with actions. As with the importing of event sheets, many groups can exist in a single event sheet.
