Checking Custom Event Variables

Is it possible to perform checks on the variables passed to a custom event?

I have a custom event with ten variables. My goal is to call the custom event and supply a certain set of variables to it. The custom event will then perform operations on only the variables passed to it.

I assume that it is possible to set an additional boolean (‘isPassed’) for each variable, pass all of the booleans through along with my desired variables and have branch nodes decide which desired variables to use, but that seemed excessive.

CustomEvent launching in other blueprint? Are u sure when exactly do u want to check this variables? Since u don’t know when Custom Event will manage to finish his execution unlike function.

The custom event is launching in another blueprint, yes. I want to check which variables are passed when the event is called.

If you left input pin node open than Custom Event will use default value, wich you can set and check if value is default inside Event.
