Server Events

Server events are events which are communicated to the server, and may affect all stakeholders. For example, a server event can automatically plan a measure or change attribute values of areas and neighborhoods, resulting in new overlay and indicator results.

Server Events can be used in multiple locations in the Tygron Platform; as part of a measure, when a scenario is activated, as part of a larger event bundle in the action menu, or during a cinematic sequence. Server Events allow for events to be triggered during a session, which will result in a reaction from the server.

Different Server Event types

There are two flavors of Server Events: Logic Events and Participant Events. The difference between these Event Types is that for Participant Events at least one dedicated stakeholder needs to be assigned to the Server Event itself as event property. A good example of this is the asking for or receiving of a money transfer (MONEY_TRANSFER_ASK & MONEY_TRANSFER_GIVE) as a Server Event.

Logic Events do not require such a dedicated stakeholder and can be fired without one being assigned as property. A good example of this is the activation of a specific area (AREA_SET_ACTIVE) when creating a flooding as part of a measure. Events like CINEMATIC_STAKEHOLDER_START are also Logic Event Types, because the stakeholder is not a property of the event, but of the linked cinematic.

NET_CLUSTER_SET_STATE	Set TimeState for all Net Loads of Net Cluster.
NET_CLUSTER_SET_STATE_FOR_NET_TYPE	Set TimeState for Net Loads of Net Cluster, based on NetType.
NET_CLUSTER_SET_STATES	Set TimeState for all Net Loads of Net Cluster.

Adding Server Side Events to a project

Add events to a scenario (left panel)

Add & Remove Event buttons (right panel)

As mentioned above, events can be added to a project element on multiple occasions and locations. Please refer to the main article relating to these elements for more information about the specific steps to take.

In general, adding Events to an element in the Tygron Platform happens on the right panel, after selecting the element (ex. measures, scenario, etc) to have an event added to on the left panel first. Select on the right panel bottom the 'Add Event' button; a default blank event named NO_DEF is created in the list above the buttons. Selecting an Event on the list and using the 'Remove Event' button deletes the event from the list.

Selecting an event on the right panel also opens up the bottom panel where the actual event type can be selected. This selection can then be confirmed on the bottom panel by using the 'Commit' button. The 'Cancel' button clears the selection on the bottom panel.

Event bundle bottom panel with 'Commit' and 'Cancel' buttons

How to add events to a project element:

1. Select Project Element to have events added to
2. Select the Event option on the left panel
3. Select 'Add event' on the bottom of the right panel
4. Select the newly added event on the right panel
5. Select the desired server event from the bottom panel
6. Confirm the selection with the 'Commit' button (or use the 'Cancel' button to clear the selection

Changing the properties of a Server Side Event in a project

The properties of events can be edited on the bottom panel (see image above). On this panel a linked ID of a measure or cinematic can be linked to an event for instance. Also can a dedicated stakeholder be selected here for Participant Type Events. Again, any changed made need to be confirmed first with the 'Commit' button, or cancelled with the 'Cancel' button.
