The thing you are doing wrong is understanding what the Blue Variable is about.
It is a reference variable. You need to fill it! It is empty by default. The Error “Accessed None” tells you
that you are trying to access the empty variable. What is TransLocation? Which specific Actor are you trying
to modify there?
You may want to watch my video about pointer/references and this error:
The variable in the CharBP has a transform value set in its BP just for a test but I want to update it often outside of the BP. I have another GET using this method and it is returning a 0 value. I have the CharBP print string and it is showing the correct value.
I deleted the variables in the blueprints trying to use the CharBP one and just used cast to CharBP and that worked like a charm. I tried it before but with the variable reference in there it was giving an error so I stopped using it.
