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, etc. 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 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

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

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.

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
