An "executable" file is a program that can run on another computer by itself, without having to be opened using another program. By exporting an executable, you can share your project with people, even if they don't have Unity installed. Follow the tutorial below to export a Mac and/or Windows executable of your project.
You've made a version of your project that can be shared with others - now it's time to share it. Read through the tutorial below to "zip" your project into an archive and upload it to share. When I teach Crafting Digital Places, students usually upload their projects to Google Drive to share. But you (or your class) might have another place where files are kept.
If you want to share your executables more widely, itch.io is a free site where anyone can open an account and share or sell their games. It's a bit like YouTube for games!
Some people may not be able to visit your world directly because they don't have a system that can run an executable (like, a phone, tablet, or Chromebook). We're also going to record a video "walkthrough" of your world that will make it easy to share with friends, family, and others. If you want, and if your caretakers allow, you might even share your video on YouTube or other social media.
If you need a refresher, the tutorial on screen-capturing with OBS is linked below.
After you record your walkthrough video, you can archive that on Google Drive, as well.
Then, take some time to visit other peoples' digital places! Record your experiences in them - will you be surprised, scared, delighted, curious...?
