Simple Game Scripting Part 1:
Storing/Reading Your Scripts - page 3 |
Loading Your Scripts
There is no real need to discuss the writing of
your script files from VB, as you can simply use
notepad or another plain-text editor to do this.
But, loading your script files into your game for
use is another story. There are numerous questions
which can be asked about how to do this, such as
how the lines of 'script' can be parsed into
separate pieces, and how to store the scripts while
in memory.
User-Defined Types - Gotta Have 'Em!
The first thing to be done is define a user-defined
type for a script command line. I suggest placing
this into a class module, probably called something
such as CScriptParser in order to allow for further
expansion in later parts of this series of articles.
| Private Type tCmdLine
Command As String
Parameters() As String
End Type
This should be placed in the declarations section
of your class module. Another useful UDT that
should be created is one for an event block:
| Private Type tCmdBlock
BlockType As String
BlockName As String
Commands() As tCmdLine
End Type
Storage Variables
To prepare for storing your scripts, you'll need a
variable array (put it into your declarations section
of the class module you created earlier as well):
| Dim CommandBlocks(1023) As tCmdBlock, iLastBlock As Integer
This creates a limit of 1024 possible blocks loaded
simultaneously. You can always increase this if
you need to. The iLastBlock variable is simply to
keep track of the last element in the array which
is occupied. You should initialize this variable
to -1 when an instance of the class is created,
so in the Class_Initialize method of your class,
put:
| iLastBlock = -1
