Chapter 2: Implementing Conditional Judgments

This chapter will guide how to set up and debug conditional branches for determining message or event types.

Step 1: Add Conditional Branch Node to Canvas​

In the right "Node List" sidebar, drag the "Conditional Branch" node to the canvas and connect it to the node from the previous step.

Step 2: Set Branch Conditions​

In the right "Node Configuration" panel, set conditions. For example, determine if the event type is a subscribe event.

In the expression panel, you can view global variables and node variables. Node variables refer to the input and output data of "debugged nodes" from previous paths, such as wxTrigger in the figure below:

Continue adding other conditions. "Priority" refers to the execution of higher-priority conditions when multiple conditions are matched.

Step 3: Add Downstream Nodes and Configure Connections and Branches​

From the "Node List", select and add other downstream nodes to the canvas. After connecting, click the connection to associate the branch.

Step 4: Debug Conditional Branch​

Select the "Conditional Branch" node. In the "Node Configuration" panel, click "Debug Node" to start debugging. For branches that meet the conditions, the "matched" field in the node output will be true, verifying the branch path.
