4. After clicking on "-", you will see all the game scripts, find the "Baldi" script and click it and click on the "OnTriggerEnter (Collider): Void" script
5. When you click, you will see all the code inside the script, now click with the right mouse button and it will show a list with options, go to "Edit Method" and click it
6. A window will open, this window you can change the game script, select all the code inside (see the image first before selecting everything) and delete it
7. After deleting everything, click on "Compile" to compile the code, or in other words, save the code inside the script
8. Then click on "File" again, and click on "Save Module ...", it will ask some questions, like the directory that will be saved, do not change anything it is showing, and just click OK
   1. The "Save Module ..." option will only be active if you modify something inside a file
   2. The "Save All" option will save all the scripts you have modified in the files
