When I needed to change a variable within an operator block, I’d been removing the variable block and adding the right one. Unlike the “change <variable> …” and “set <variable>…” blocks, the little variable name bubbles do not have a drop-down selector. Today, Anya and I were working on our Chicken Keepers games and she right-clicked the little bubble to select a different variable. Totally didn’t realize you could do that.
