(: It’s no problem to be that guy. You click the yellow “Return Value” of the left node and drag it into the EventGraph. Just to an empty place. Now a window pops up. Here you type what you are searching for. In this case “Vector plus Vector”. A normal “+” would also be enough, you should see “Vektor + Vektor” and “Vector + Float”. Just click on “Vector + Vector” and the node appears (:
