Output category

Description

This category contains nodes that you can use to make data values from your graph available to other Flow graphs, or to Lua scripts.

When you use this node in a unit Flow graph, in a Flow graph that you assign to an entity, or in a Flow subroutine, a new output data connection becomes available on the Flow node that represents this unit, entity or subroutine in other Flow graphs. Whenever your other Flow graph reads the data from this output data connection, the value it receives is the last value passed by this unit, entity or subroutine into the External Output node.

For example, the following image shows a Unit Flow that contains an External Output String node named Custom variable. When a Data > Level Unit node for this unit is included in a Level Flow graph, it automatically offers an output connection with the same name. When the Level Flow graph reads the value from this output connection, it gets whatever value the unit Flow graph last passed in to the External Output String node -- in this case, the string produced by the Get Unit Level Name node.

In addition, you can read external output variables from Lua by calling stingray.Level.flow_variable(), stingray.Unit.flow_variable(), or stingray.FlowComponent.flow_variable().
