When you open a scene (or external events), the Events Editor is present as a tab.

The Events Editor is where you add the events that create the actual gameplay. All the “rules” of your game can be created using events. The Events editor is a tool that gives you the power to visually program your game. Events are readable by anyone and can be authored without advanced programming knowledge.

When editing a scene, to switch between the Scene editor and the Event editor, use the tabs at the top of the window.

When you switch to the Events editor, you will see that the toolbar changes to display new tools:

Add an event by clicking the “add event” button

When you click this button a blank event will appear on the screen below in the editor

You can add any number of event blocks to the Event editor. Each event can have various conditions and actions. Once you add an event, you can use the conditions and actions to create the game's logic. Learn more about events, on this page: Events.

By clicking the “Add a sub-event” button, you can add a “child event” block to the selected event.

After clicking the button, a blank sub-event appears below our selected event.

Sub-events are executed only if the parent event's condition(s) are true. Sub-events provide a way to avoid repeating the same conditions. They make the logic much easier to read.

By clicking the “Add a comment” button, you can add comments to the list of events. Comments are useful to add explanations to complex events. They can contain any arbitrary text.

Comments are an important part of any game or application. They help you to organize your events and give an opportunity to add notes or explanations about what the events are doing.

By clicking the “Add an event” button, along with the ones we already mentioned, we have access to some special events.
