Patch:High Scores (Vorticons)
This page deals with patches that relate to the high scores in Keen Vorticons. In Keen Vorticons, the High scores have two main components, the main level screen where they are displayed, and the window that appears when the player gets a high score. This second component is part of the game over sequence and is treated on that page. There is also the default score names, a list of three names used to build the high scores when no SCORES.CKx file is found. As such this page will be divided into two main sections; the default score names and the high scores window.
High scores screen
In Keen Vorticons, the high score screen is what is used to display the high scores. This is in the main menu level and shows a list of scores and names as well as some bitmaps. Keen 1 shows ship part tiles got and Keen 2 number of cities saved.
Location of screen in Main Menu level
The high score screen is located int he same level as the Main Menu, but at a different location. This location (horizontal and vertical) is defined by four variables. The biggest two define the location in sixteens of tiles. (This a value of 5 is 5*16 or 80 tiles across the level.) The smaller two variables are in 256ths of a pixel meaning that on1 pixel is $100.
Given these rather odd units the default location of the high scores is 80 tiles plus 64 pixels (= 84 tiles) horizontal and 0 + 32 pixels (= 2 tiles) vertical.

Names, Scores, Parts, etc
The high score table has at least three bitmaps used to head the various columns of the high score table. each entry in the high score table has a figure (or tile) in these columns.
Bitmaps used for high scores
There are three of four bitmaps used in the high score screen. The first is the screen's title while the other two or three are the titles of various columns in the high score table. It is possible to alter what bitmaps are used and where they are located.

Names and\or scores use the other kind of text
In Keen Vorticons there are two kinds of 8x8 text that can appear in a window, 'normal' and 'white'. These patches change the high score screen so that the score or name in each entry uses the second kind of writing instead of the first. Each line is independent.
Keen 1
#Highscore text uses white backgrounded writing
%patch $99FA $E8 $C8D5W #Score
%patch $9A10 $E8 $C8BFW #Name
Keen 1 ship parts
If Keen has acquired any of the ship parts during he game in which the high score was obtained, this will be recorded in the high scores window a line of up to 4 ship parts tiles. Note that the locations of the ship parts are covered in the locations section above.
This patch changes the ship tiles used. By default the tiles will animate, using the next three frames. This allows the high scores to animate tiles that don't animate in-game.

Default score names
When Keen is run with no SCORES.CKx file present, score entries are read from a default list of three names (default score is 100). The list thus repeats twice. (6 scores.)
Score file to look for\write to
Before the game creates a set of default scores it checks to see if the 'score read' file (plus game extension) is present. If not, default scores are created. When the game is quit another file 'score write' is created or updated. By default both of these filenames are the same, if they are not scores behave in odd ways. See Patch:Files and filenames.

Default scores
By default all default score entries have a score of 100. The value of this can be changed. The score has two variables, the 'low' and 'high'; the high variable is multiplied by 65535 and added to the low.

Number of different default names and name text
The score names are loaded as a single block of text that is then cut up into a number of names of a certain length. By default a block of text $2D (45) letters long is loaded cut up into 3 names of length $0F (15).
If the number of names exceeds the block of text some names will be blank. All names will be the same maximum length with their actual length depending on how many letters are in the name. (By default these are 5, 7 and 6 letters.) Name length includes any terminal $00s. Names repeat in sequence until the required number of high score entries is filled.
