Clamp in Unreal Engine 5 C++
The Blueprint Clamp node maps to FMath::Clamp(A, Min, Max) in C++, constraining a value between a minimum and maximum.
Blueprint node & C++ equivalent
float A;
float Min;
float Max;
float Result = FMath::Clamp(A, Min, Max);What does the Clamp node do?
Clamp restricts a value so it never falls below Min or rises above Max. If A is inside the range it is returned unchanged; otherwise the nearest bound is returned. FMath::Clamp(A, Min, Max) is templated, so it clamps floats, ints, and other comparable types.
How to use it in C++
Write float Result = FMath::Clamp(A, Min, Max);. Keep Min less than or equal to Max, because the implementation checks the lower bound first and an inverted range collapses every input to Min. Clamp is commonly used to keep health, alpha values, and camera pitch within valid limits.
Frequently asked questions
What is the C++ equivalent of the Clamp node in UE5?+
It is FMath::Clamp(Value, Min, Max), which returns the value limited to the inclusive range between Min and Max.
Does FMath::Clamp work with integers?+
Yes. FMath::Clamp is templated, so the same call clamps int32, float, and other comparable types.
