The code is in the project. Click see inside, and there should be a little strip on the bottom of your screen that says; "Backpack". Click on the backpack strip, then drag the code inside the project into the backpack. The code should save, and when you need to use that code in any project, click the backpack strip, drag the square with the picture of the code into the code section of the sprite you want it on. Also, you don't have to credit. OK, that's it, hopefully that helped with whatever you're doing!
