Server Events
What is a Server Event
- Main article: Events
Server events are events which are communicated to the server, and may affect all stakeholders. An example of this is the activation of a measure. These events may affect the 3D world and the indicator scores.
How do Server Events relate to the Tygron Engine
Server Events can be used in multiple locations in the Tygron Engine; as part of a measure, at the start of a level, 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 Player Events. The difference between these Event Types is that for Player 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 terrain type (TERRAIN_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.
Logic Event Types
Below is a list describing the available Logic Server Event Types:
| ACTION_MENU_SET_FUNCTION_AVAILABLE | Add or remove a function from a particular Action Menu |
| ACTION_MENU_SET_MEASURE_AVAILABLE | Add or remove a measure from a particular Action Menu |
| ACTION_MENU_SET_UPGRADE_AVAILABLE | Add or remove an upgrade from a particular Action Menu |
| BEAMER_SET_LAYER | Set the beamer layer to a specific overlay type |
| CINEMATIC_STAKEHOLDER_START | Start a cinematic for a specific stakeholder |
| CINEMATIC_STAKEHOLDER_STOP | Stop any cinematic for a specific stakeholder |
| LEVEL_SET_ACTIVE | Activate a game level |
| MEASURE_UPDATE_CUSTOM | Update a custom made measure |
| MESSAGE_ACTIVATE | Activate a specific message |
| MESSAGE_REVOKE | Revoke a message. Effects are not revoked |
| MESSAGE_RESET | Reset a message. Sets the message as inactive and clears the send date. |
| SETTINGS_ALLOW_GAME_INTERACTION | Allow interaction with the project during a session, after a pause moment or level switch |
| SETTINGS_SET_MESSAGE_AUTO_RESPOND | When activated, messages to non-human players and session facilitators are automatically replied to |
| SPECIAL_EFFECT_SET_ACTIVE | Activate/deactivate a special effect |
| TERRAIN_SET_ACTIVE | Activate/deactivate a terrain |
| TERRAIN_SET_POLYGON | Activate/deactivate a polygon as terrain (Safe Zone, Flood Hazard Zone, etc) |
| TIME_SET_SIM_MULTIPLIER | Set the game time multiplier. A value of 1 means that 1 sec in real life is also 1 sec in simulation time. 2 means 1 sec in real life is 2 sec in simulation time |
| UNIT_SET_ACTIVE | Activate/deactivate a unit (vehicles etc) |
| WEATHER_SET_DATA | Set rain data of the weather |
| ZOOMLEVEL_SET_ACTIVE | Activate or deactivate a zoom level |
Player Event Types
Below is a list describing the available Player Event Types:
| ACTION_MENU_SET_ACTIVE | Set a category of actions available for a stakeholder |
| MEASURE_CANCEL_CONSTRUCTION | Cancel a measure planned by a stakeholder while in pre-construction phase |
| MEASURE_PLAN_CONSTRUCTION | Plan construction of a measure by a stakeholder that is not yet planned |
| MESSAGE_NEW | Send a message between Stakeholders through the message panel |
| MONEY_TRANSFER_ASK | Ask for money from one stakeholder to another |
| MONEY_TRANSFER_GIVE | Give money from one stakeholder to another |
| SETTINGS_SET_ALLOWED_WATER_LEVEL_INCREASE | Set the maximum allowed water rise amount in meters in 'polder water' (= open water) |
Adding Server Side Events to a project
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 Engine happens on the right panel, after selecting the element (ex. measures, levels, 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.
- Select Project Element to have events added to
- Select the Event option on the left panel
- Select 'Add event' on the bottom of the right panel
- Select the newly added event on the right panel
- Select the desired server event from the bottom panel
- 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 Player Type Events. Again, any changed made need to be confirmed first with the 'Commit' button, or cancelled with the 'Cancel' button.
