in an action after you call function MMC, you get set a variable to Function.ReturnValue

or use Function.ReturnValue in an expression

you can also use the expression Function.Call() which will trigger the function and return its value in the expression

"Function expressions

Call

Call a function directly from an expression. The expression returns the return value that was set in the function, or 0 if no return value was set. Additional parameters can optionally be added after the name of the function, e.g. Function.Call("CreateEnemy", 123, 456)."
