An '''external script''' is a script file used only in San Andreas that is outside the main script file, the <code>[[main.scm]]</code>. An external script is a compiled binary file having an extension <code>.scm</code>. It contains the opcodes which are parsed by the game in the same way as the ones located at the <code>main.scm</code>. The difference from an ordinary SCM file is that an external script has no header. All the info about it is compiled at the <code>main.scm</code> header.<br>

A streamed script is a script file that is streamed on demand, only when the script needs to be executed. They are stored in the script.img file. It contains the opcodes which are parsed by the game in the same way as the ones located in usual scripts, except that it has no header.

GTA San Andreas

The file is located in the data/script/ directory and is loaded by gta.dat.

The maximum number of streamed scripts that can be defined is 82. The maximum number of streamed scripts that can be used simultaneously is 70. The game currently has 78 defined streamed scripts.

Tutorial

In order to add more external script files, you have to define the number of files you are going to use:
DEFINE EXTERNAL_SCRIPTS 78
Add the external script to the list with this:
DEFINE SCRIPT NAME AT LABEL
At the end of the file add your code in.
