Passthrough Block

​

Overview

The Passthrough Block is a simple utility that passes input values to outputs without any modifications. It’s useful for scenarios where you need to route values through specific paths in your flow without altering them, such as grouping values from different branches or controlling wire flow.

​

Key Features

• Dynamically creates input and output ports based on connections
• Passes values through without modification
• Hidden by default in the block menu
• Useful for organizing complex flows

Example: Grouping Values

1. Create multiple branches in your flow that produce different values.
2. Add a Passthrough Block at the point where you want to group these values.
3. Connect the outputs from different branches to the Passthrough Block’s inputs.
4. The Passthrough Block will now group these values without modifying them.

​

Error Handling

The Passthrough Block does not perform any error handling. It simply passes through whatever values it receives on its inputs to the corresponding outputs. If an input is control-flow-excluded, the corresponding output will also be control-flow-excluded.

Technical Details

• The block dynamically creates input ports based on the highest numbered connected input port plus one
• The number of output ports is always one less than the number of input ports
• Input ports are named “input1”, “input2”, etc.
• Output ports are named “output1”, “output2”, etc.
• The block belongs to the “Logic” group in the block menu
