Alden's Overly Complicated Portal 2 Puzzle Creator Guide
By Alden
It's probably been a while since you beat Portal 2. You've probably even played some of the 300,000 community-made puzzles. But how about trying your own hand at the Portal 2 Puzzle Editor? Its really not that hard. This guide aims to make even the easiest editor even easier to use.

Or maybe this makes it harder. The point is actually just to demonstrate what you can do with the new Game Guides system we've added to the Steam Community.
Getting to the editor
To find the puzzle editor, click "Community Test Chambers" and then "Create Test Chambers"

Then select "New Test Chamber" and click the "Next" button at the bottom
Adding items
You're now in the editor with an empty room. You've got an entrance and an exit, but no way to trigger the exit.

So, start making your room interesting. Drag your mouse to select grid squares on any of the walls. Then you can click on the corner of your selection to expand or contract your room.

Now you can add some elements to make your puzzle interesting. At a most basic level, you should have a button to trigger the door.

Then a box to let you weight the button...

Now you've got a playable map.
Testing your puzzle
To test your map, you first need to rebuild it so your editor changes get converted into a playable map. Select "Rebuild" from the drop-down menu. When it finishes rebuilding, you'll be in the map.

Play around, place the cube, and see your map work.

Testing and editing over and over will help refine your map and make sure its fun and challenging. Once you have something you want to share with the community, you can publish to the Steam Workshop.
Publishing to the Steam Workshop
When you're all ready, select "Publish" from the drop down menu. You can then enter a name and description. Once you hit "Publish Test Chamber" your work will be uploaded to the Steam Workshop.

The End. Here is the map that I created with this tutorial:

Yeah, how exactly is this complicated? I've already made 4 chambers.

@inspirata i do. Infact, before designing it in the editor, i draw it out on paper. and i also try to keep to valves style of tests.

So simple to use....now why people don't save their brain power (and time) for coming up with good tests I won't know.

Thanks for the guide. Where to find the editor was the step that I was struggling with.

Good example of a guide, even if the content is rather simple.
