The flow route is a directional link that connects two events on the same layer. Together, the routes define a flow logic: the order of events on each layer, and when the events are switching. Four types of the routes are available, depending on how they gate the event flow: ‘time’, ‘condition’, ‘time or condition’ and ‘time and condition’. The default ‘time’ routes take an account a predefined duration of the source event, whereas 3 conditional route types also rely on a conditional code that can be attached to the route. The conditional code is a logical expression, written by an user. The condition is continuously evaluated by the program at runtime and a route gets open when the expression returns true.

Things To Know ¶

• Switching between two events occurs only if the 'between' route exists AND the route is open. The programs continuously evaluate all outgoing routes of the current event and opens a particular route once its conditions are met.
• Flow routes allows logic branching when two or more routes originate from the same event and are controlled by different conditions.
• The routes are directional, in order to make a two-events loop, two routes have to be created with opposite directions
• Event that has no incoming routes will never be activated, unless it's the first event on the layer
• When multiple outgoing routes become open at the same time, the first route by creation order is used. The order can be changed in GUI

Recurrent route ¶

Example of flow logic

Recurrent route is a special type of route that has the same source and target event. The recurrent routes are used to build a sequence of frames of accurate durations (e.g. RSVP streams or any animated stimuli, like the random-dot motion). The recurrent route is created in the flow route panel by dragging a link out and into the same event.
