Select Node in Unreal Engine 5 C++UE Docs
The Blueprint Select node picks a value based on a condition, which in C++ is the ternary operator: int32 Result = bCondition ? OptionA : OptionB;.
Blueprint node & C++ equivalent
// Blueprint "Select" = ternary
int32 Result = bCondition ? OptionA : OptionB;What does the Select node do?
The Select node returns one of several input values based on an index or boolean, without changing execution flow. With a boolean condition it simply chooses between two options, making it a pure data node rather than a branch on the execution wire.
The C++ equivalent
For the two-option boolean case, use the ternary operator: int32 Result = bCondition ? OptionA : OptionB;. When bCondition is true the expression evaluates to OptionA, otherwise OptionB. This is an expression, not a statement, so it returns a value you can assign directly, exactly like the Select node's output pin.
When to use it
Reach for the ternary when you only need to pick a value, not run different code. If you have more than two options or an integer index, a switch or a small lookup array reads more cleanly than nested ternaries. Keep both branches the same type so the result type is unambiguous.
Frequently asked questions
What is the C++ equivalent of the Blueprint Select node?+
The ternary operator. A boolean Select becomes Result = bCondition ? OptionA : OptionB;, which returns one of the two values based on the condition.
Is Blueprint Select the same as a Branch in C++?+
No. Branch changes execution flow and maps to if/else, while Select only chooses a value and maps to the ternary operator without altering which code runs.
