Patch:Status Window (Vorticons)
Jump to navigation
Jump to search
The status window in Keen Vorticons appears when the spacebar is pressed during normal gameplay. It displays what Keen has, keys, shots, score and suchlike. This page covers patches relating to this window, divided into two sections. The first section contains patches relating to the window's behavior, what causes it to appear and what it does. The second section contains patches that relate to what the window looks like, its construction and content.
Patches for other status windows can be found at Patch:Status_Window_(Galaxy) and Patch:Status_Window_(Dreams). These patches also require some knowledge of Patch:Game stats and Patch:Text patches
Disable status window
This patch completely disables the status window, meaning it cannot be called during gameplay. The map is treated differently from levels, meaning it is possible to disable the status window in only one of these.

Status window behavior
This section contains patches that alter how the status window behaves, what causes it to appear and what it does.

These patches change what key activates the status screen. By default this is the spacebar. in the example here it is changed to enter. Using these patches requires some knowledge of Patch:Scancodes.

Galaxy style status window controls
This changes the controls of the game to be more like Keen Galaxy. Spacebar shoots, enter brings up the status screen. See #http://andy.durdin.net/keen/modding/viewtopic.php?t=433 for the original topic. In essence this is a longer version of the above patches, with extra lines altering Keen's shot keys.

Status window construction and appearance
Status screen appearance
The status screen is at heart a text window with 16x16 tiles drawn over it at certain positions, followed by variables like the score.
For text, a lot of 'short lines' (separators) little more than one character long are used, as well as some 'long lines' with actual labels on them. Short lines are often shifted across a few characters.
There is also a 'big versatile status screen patch' that allows total customization of the Keen 1 status window. It is the last entry in this section.

Change the lives sprite
This patch allows the sprite used for lives to be changed. The first blue value is the sprite used * 4. (Here sprite 31 x 4 = 124 = $7B.) The second blue value is the vertical position of the sprites, originally this was 3 but because of he patch it must now be 9 larger (12 or $0C). This patch is incompatible with several of the patches in the above section that alter the lives counter.

The big versatile Keen 1 status box patch
This patch fully customizes the status window, allowing the smart patcher to remove or rearrange things to their will. Along with the tiles and variables, it contains their positions and even allows entire blocks of code to be skipped. In addition to this, it frees up space for use with other patches.
The status file is just an external text file of 392 bytes in size. A default example can be found here: STATUS.CK1
Values in brown are related to Patch:Item bytes which control *what* is shown, or jumps which control whether or not something is shown. Values in blue are positions (In 8x8 tiles) or 16x16 tiles displayed
