Where is definition of "SetVectorUnitRandParameter()" function?

Development Programming & Scripting

Where can I find definition of function?:

/**

  • Set a named random unit vector instance parameter on this ParticleSystemComponent.
  • Updates the parameter if it already exists, or creates a new entry if not.
    */
    void SetVectorUnitRandParameter(FName ParameterName, const FVector& Param, const FVector& ParamLow);

This declaration is in file the “ParticleSystemComponent.h”.
in line 1632 (UE 5.0.3). In UE4 it exist but in other line.

I want to see how the function is declared. I can’t find declaration of this function in code :frowning:
