There should be a consistent gap between our pipes. Let's make that 150 for now.
- Change the height parameter in top_pipe to (350 - pipe_height).
- Go to and drag Set Top into your interval event.
- Change the name in front of hte action to top_pipe. Change the parameter to 250.
The height of the bottom pipe + the height of the top pipe + 150 will equal 500: the height of the screen!
