Uploading Addins

The process for uploading addins should be fairly intuitive. From the "World of Goo Addins" menu along the top of the screen, choose "Upload an Addin".

You are prompted for some basic information about your addin: the name, description and type. The description can use limited HTML including hyperlinks, lists, headings and so forth.

The addin type should be one of the following:

Chapter
A set of levels that replaces a chapter in the original game.
Level
A new playable level.
Level Pack
A set of multiple levels, all of which will appear in Chapter 1 (Unlike a Chapter addin)
Ball Style (World of Goo Corp)
Changes the appearance of balls in the World of Goo Corporation.
Ball Style (Other)
Changes the appearance of other balls in game (e.g. Ivy, common).
Theme
Changes the graphical appearance something in the game, whether a level, chapter, or the UI.
Utility
Something that runs outside of the World of Goo, such as GooTool or wogeditor.
Sample
Example addins, such as demonstrations of functionality. Not generally useful for a player.
Other
Any addin that doesn't fit into one of the above categories.

Screenshots and videos

You can upload as many screenshots as you like. They will automatically be thumbnailed to appropriate sizes (currently 200x200 in the addin page and 150x150 in preview teasers), and the user can click on them to see the full version. The first screenshot in the list is the one used for the previews of this addin.

You can also link to YouTube videos, which will be automatically embedded in your page. Just enter the full YouTube URL, for example http://www.youtube.com/watch?v=jzWkQk9zfy4

Note that you can rearrange the order of both screenshots and videos by dragging the little handle on the left of each row.

Downloads

Once you've saved your addin, you can go to the "Downloads" tab and upload attached files. Once they're uploaded you can edit them or change their state.

Live
The download is active and is shown on your addin page.
Archived
The download is not displayed by default, but can be shown by clicking "Show archived downloads", and can still be downloaded by users.
Deleted
The download is effectively deleted. Users cannot see or download it; it is only visible to the author. It is never actually deleted because we keep download statistics for old versions.

Publishing

When you first create your addin, it is not yet visible to the public. You will see an orange box at the top of the page warning you about this. However you can continue to edit the page, including screenshots, videos, and downloads.

Once you have completed your page, you can click the link at the top to tell us your addin is ready for publishing. Note that you cannot do this until you have uploaded files and added a description. Also note that we will not publish an unfinished page.

Taking addin screenshots

Most addin pages should have at least one screenshot. This is used to give people a preview of the addin, a little taste of what the addin looks like. It also makes the page a little more colourful and appealing.

This page explains how to take and save screenshots.

Windows

In Windows, you can take a picture of the screen using the Print Screen button on your keyboard, which is usually written as PRTSC or PRTSCN. On some laptops you may have to hold down a Function (Fn) button while pressing the Print Screen button.
When you press Print Screen, everything you currently see on the screen is copied to the clipboard, which you can then paste into a program such as Paint. You can then save this as an image file. For goomod screenshots you should save this as either a JPG, PNG, or GIF file.

So to take a screenshot of your level, play your level, and when you want to take a screenshot press Print Screen on your keyboard. Then exit World of Goo, paste the image into Paint, and save as one of the file types mentioned above. Then upload it to your addin page and you're done!

(On some graphics cards, World of Goo may need to be in windowed mode for you to take screenshots. In this case, you can Alt+Enter to change to windowed mode and use ALT+PRTSCN to take a screenshot of only the active window.)

Mac OS X

On a Mac, you can save a screenshot directly as an image. Press Command, Shift, and 3 at the same time, and it will automatically save a picture of your entire screen to the desktop as a PNG file.

So to take a screenshot of your level, play your level, and when you want to take a screenshot press Command+Shift+3 on your keyboard. Then exit World of Goo, upload the image on your desktop to your addin page and you're done!

(On some graphics cards, World of Goo may need to be in windowed mode for you to take screenshots. In this case, you can press Command+Shift+4, then space, then click on the World of Goo window.)

Linux

It depends on the distro, but generally identical to the Windows instructions (PrtSc or Fn+PrtSc to copy the screen to the clipboard). Some distros (KDE-based ones, for example), will pop open a window you can directly save the screenshot from. If not, just paste into GIMP or your image editor of choice and save as PNG, JPEG, or GIF.
