Twilight/Parameters
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Parameters
The parameters which are shown in the parameters pane are described by a
description in the effect. This area is created by the controldes program,
and is specified by a text file. Knowledge of the format of this area is not
necessary because of this, and it should not be assumed as it may change
(but not in an incompatable way) in the future. The format is not described
here.
There are five types of parameter you can use in an effect:
value
slider
menu
switch
text
To see what they look like, look at the effects supplied with Twilight.
Each of these types is specified by a line in the text file given to
controldes begining with a ':'. Any other line is regarded as a comment. You
should be aware that there is no error checking on the input file. If you
put rubbish in, rubbish will come out.
In the syntaxs below, it should be obvious wether a string or a number is
expected. If not, look at some of the example description files. Strings do
not need to be enclosed by "s, but are terminated by a ','. No string should
be a null string. Use a ' ' instead.
The default value is always a number except for a text parameter.
Appending control description
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The controldes program is used to append this. It's syntax is:
controldes <effect name> <code name> <textual description name>
end of description
~~~~~~~~~~~~~~~~~~
syntax:
:e
This shows the end of the text file. If it is omitted, it will be accepted,
but strange things may happen.
value
~~~~~
syntax:
:v <min>,<max>,<name>,<default>
This create a value icon where the user may type in a number. Use it where
the number of not expected to be changed (such as number of fish), or the
number matters. The value is kept within the limits specified.
slider
~~~~~~
syntax:
:s <name>,<first value>,<last value>,<start label>,<end label>,
<units>,<default>
NOTE: only four sliders may be used. Any more may crash the control panel.
This creates a slider. Use when the number doesn't actually need to be
particually accurate.
menu
~~~~
syntax:
:m <title>,<entries>,<default entry>,<entry 1>,<entry 2>,etc...
NOTE: default entry is numbered from 1, but is passed to effect numbered
from 0
NOTE: only four menus may be used. Any more may crash the control panel.
A menu with a displayer for choosing from a list of selections. A random
option is always nice to have.
switch
~~~~~~
syntax:
:w <name>,0|1
0 - off by default
1 - on by default
A switch. Returns 0 - off, non-0 on in parameter block.
text
~~~~
syntax:
:t <len>,<name>,<default text>
NOTE: If a text string is just one ' ' then a null string will be put in the
icon. If a null string is entred in the icon, a string consiting of
one ' ' will be passed to the effect.
A icon for entering text.
Format of the parameter block passed to the effect
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This parameter block is block of words. Entries are in the order of the
parameters. Each entry is a value, except in the case of a text parameter,
where it is a pointer to a null terminiated string.
