Just like with the scoreGroup and the elapsedGroup, we look up the powerupGroup node that contains the labels and set the position, taking the scene size into account. In this case we’re setting the x-coordinate to zero, which is dead center of the node, and the y-coordinate to the top of the scene minus the calculated height of the group node.

With the power-up labels positioned and ready, we can fetch them at the start of the ‑showPowerupTimer: method.
