  1. Click anywhere in the CPU Usage graph
    • We can see that our Update method is taking up a much larger portion of the frame
  2. Change the bottom section of the profiler from timeline to hierarchy view
    • The timeline view is a good visualization, but the hierarchy view provides more actionable information
  3. Order the hierarchy view by “Time ms” and expand “PlayerLoop” all the way down to the script logic
    • By ordering the view by “Time ms” we can narrow down what is taking the CPU so long to execute
    • FindObjectsOfType is taking up some time, so let’s fix that
  4. Switch to Visual Studio
  5. Convert interactables to a private member variable
  6. Initialize interactables in the Start method
    • It’s best to initialize this at the start of the scene instead of every frame
    • This works because we know our scene won’t change

We decreased how long it takes for our script to run each frame but we aren’t done
