- All commands on one line separated by commas.
(note that BobCob automatically places each command on a separate line for easy viewing)
- a single space between every operand
- a single comma (no space) between every command (this will not be visible in BobCob)
- square brackets round strings e.g. [filespec]
- All opcodes must be lowercase
- labels should be lower case, exactly 4 chars long
- object names should be exactly 4 chars long, case does not matter
LVALUE, object operands:
NOTE: the HandleActivate() functions *assume* success, and therefore
change the activity status of the object automatically (to ACTIVE1 etc).
I only need use this command if I need to *override* the change, for
example, 'one-shot' activations (for example an obj that just makes a
sound when clicked on) should deactivate themselves at the end of the
macro, otherwise further activations will be suppressed, since the object
is now permanently ACTIVE.
Below is a table showing the COB file structure:
| BYTE | DESCRIPTION | ||
| 01 | Always (?) has values: |
01 | |
| 02 | 00 | ||
| 03 | number of objects available (perhaps not using byte 04) | ||
| 04 | |||
| 05 | month | Date of expiration (set to 00 to make "immortal") |
|
| 06 | |||
| 07 | |||
| 08 | |||
| 09 | day | ||
| 10 | |||
| 11 | |||
| 12 | |||
| 13 | year | ||
| 14 | |||
| 15 | |||
| 16 | |||
| 17 | Number of scripts | ||
| 18 | |||
| 19 | Number of imports (usually one - the INST section) | ||
| 20 | |||
| 21 | Number of objects used | ||
| 22 | |||
| REST OF COB |
Script Strings | Byte 1 = Length of string. If FF then bytes 3&4 determine length | |
| Import Strings | Byte 1 = Length of string. If FF then bytes 3&4 determine length | ||
| Image Data | 01 | Width | |
| 02 | |||
| 03 | |||
| 04 | |||
| 05 | Height | ||
| 06 | |||
| 07 | |||
| 08 | |||
| 09 | 2-byte width repeated (?) | ||
| 10 | |||
| 11 | (If width/height are 0, there will be no data) Same as .spr sprite image data, but with the rows in reverse order, (upside-down); note that the columns still go left to right. | ||
| Object Name String | Byte 1 = Length of string. If FF then bytes 3&4 determine length | ||
| 0 - one byte | |||
