Scripting tutorial for Arma1 is basically as valid in Arma2, nothing much has changed in code flow or how the code is executed.
There's also more scripting commands to use in A2.
There is no tutorial in this universe on anything that would magically teach you everything in a second, you need patience and time, just like Worldeater says in the BIF link he posted (obviously I'd prefer you'd used our
Command Reference instead of the mentioned BIKI
):
"You're not expected to understand these articles the first time you read them. So read them again. And again. Learn to teach yourself. Ignore all the stuff about SQS and focus on SQF. Do not stop if you don't understand something but read on. If you're stuck come back and ask."
And do just that, read the linked articles.
IMO the linked
Cheetah's basic sqf is the most basic you can get.
I do understand your frustration, I still remember it vividly how incredibly frustrating it was trying to understand how things worked. And it took me at least a year to even write my first semi-functioning script.
There were even less tuorials available back then, all I did was read some basic scripting tutorial here and then download a few scripts and try to decypher them. It slowly started to make sense.
That was well over 10 years ago and I still don't understand all of the stuff possible, I mean everytime someone comes up with a script that does some neat stuff I find things in them I have no idea how they work.
One of the best ways to learn is to download scripts made by others and study them and try to understand how is it that the script does what it does. And do that with scripts that do very very simple things and move on forward from there.
There are various types of scripts available at our site, in the
Editors Depot (can be sorted by game for example).
Arma1 sqf scripts are as valid as Arma2 scripts for learning purposes.
