Answer 1

Make it a class field

Answer 2

Roman is absolutely right.
Now you are creating a variable, but it remains in the place where you created it.
Or you must have a class field, in which case it would be player.PeremenayaA= true;
Either the function must take a value, such as private object ApiFunction(PeremenayaA) and be called in the same place where you create the variable.
