Patch:About Id

From KeenWiki
Jump to: navigation, search

The About Id screen is found in Keen Vorticons and displays information about Id Software. The screen is part of the main menu level and contains some text and a bitmap.

The text setup on this screen is unusual, it was possibly designed as an experiment in displaying text with margins, but was evidently abandoned. While several lines of text are displayed, they are all printed from one location. The screen takes a chunk of text then reads segments every x charters, writing them one after another. Thus the line of text reading 'This is*****a line******of text.****' where '*' is character 0 (Blank) reads as "This is a line of text." if the 'line length' is 12. (The * aren't displayed. Note the text segment length is (number of lines) * (line length))

This achieves the exact same effect as just having one long line of text with $0As to move down a line. (See Patch:Text patches) This can be achieved by setting the number of lines to 1 and the line length to a large value like $0200W (512 characters.) This avoids having to worry about line length and number.


Bitmap

The bitmap acts like the screen title. It is a single graphic displayed on the screen. Animating tiles will appear over it the first time they animate. While the h position on the screen is in pixels, the v position is in 'lines' or 8 pixels. (A value to 4 is thus 24 pixels down.)

Text

This is the text. As noted above, it is horrendously complicated to patch, though it can be made simpler. The following patches are set up as if the default approach is used, giving the maximum line length. Any line can be shorter than this, but MUST end with $00
