Introduction to scripting
This tutorial should hopefully take from being a leecher to a small contributor to the forums and this introduction aims to set standards for the rest of the tutorial.

First of all, I fully encourage you not to follow it. I hope to create an interest in scripting where by you want to learn by playing with the language rather than reading what I say as what I say can get very dull.

I do not plan on teaching you how to make macroing scripts. Instead, I plan on giving you logical skills, basic scripting skills and basic Scar & SRL knowledge. This should allow you to produce scripts, but will focus on fixing scripts.



- Basics
A script, at the least, only requires 2 lines:
[scar]begin
end.[/scar]
begin is the start of a grouped section of code and end shows the closing of this grouped code. If then end is followed by a . then it means that this is the end of the script - nothing else will be run when it gets this far and any code beneath it is ignored. Usually an end will have a ; after it.

A popular optional is to have a program name, which is set by doing
[scar]program MyFirstScript;[/scar]
but it does nothing and only affects one other thing that is quite unimportant now. There are rules to what it can be, but mainly no spaces - more depth will be given later.

For types, there is a handful of main ones. Booleans are either true or false. A real life example, "Is my foot on fire" - it either is or isn't. Chars are single letters - they can anything from 'a' to '~' or ones you can't directly see (like the enter character). Strings are just a load of characters joined together, like 'hello' or 'oh hey there!'. Integers are whole numbers, such as 7 or 42 or 69. Extended numbers are numbers that don't have to be whole, such as 4.2 and 8.007 (it can also be a whole number).
