Overview.html
Introduction
An overview is optional. It appears on the notebook before you start a mission or campaign. Optional simply means the game wont crash without it, but, it adds polish to your creative efforts. When you click on a single mission or in campaign mode, on the right, you see an overview, which is mostly comprised of a picture and one or two lines of text. Alternatively, you could un-PBO an existing mission and use its overview.html as a template.
The overview.html applies to:
* single missions, * a campaign, and * individual missions of a campaign.
The overview of a mission within a campaign is not visible until after you have played that mission. The intent of all overviews is to simply provide a brief 'idea' of what the campaign/mission is. The keyword is brief, because real estate on that notepad is at a premium.
Version numbers and mission author details should really be kept to the ReadMe.txt file.
Details
Many people have trouble creating a good overview picture. Pictures must be in the following sizes keep in mind that very large pictures will not fit on the page.
64x64 128x128 256x256 512x512 1024x1024
Many simple html tags will work in the briefing.html or overview.html. For an added touch of professionalism, centre your text by adding the following above your main body of description.
