== Introduction ==

This page should give beginners an overview of how to begin with scripting and where to find most of the information they need in the beginning. Some information might not be complete and can be found on other wiki pages.

During [[ArmA: Mission Editing|mission editing]] and [[ArmA: Addon Editing|addon editing]] you may come across situations where actions or features you would like to have in your mission or addon cannot be accomplished using the basic (or even the more advanced) capabilities of the [[ArmA: Mission Editor|mission editor]] or within config files (in the case of addons). Some examples of this might be really cinematic cutscenes in missions or special animations for an addon.

The '''solution''' to this is to take advantage of the game-engine's ability to call on an even more advanced feature known as [[Scripting|scripting]]. '''Arma''''s '''scripting language''' gives you a more direct control of core game features. With any combination of these '''[[:Category: Scripting Commands|commands]]''' and '''[[:Category: Functions|functions]]''' you can create custom processes that meet the specific needs of your mission or addon.


== Before anything ==

=== Is your idea necessary? ===

* Will players even notice or use what you want to script? Just because you can doesn’t mean you should. Sometimes less is more!

=== Is it possible to do this in the editor? ===

* [[Eden Editor]] is an incredibly powerful tool and with it alone one can achive a lot of things, even without writing a single line of [[SQF syntax|SQF]].
* ''Poorly written'' scripts are often the reason for poor performance both in singleplayer and multiplayer scenarios.

=== Can it be scripted using SQF? ===

* This might be hard to answer, especially for beginners. Try to get as much information about what you want to do and what [[:Category: Scripting Commands|commands]] and [[:Category: Functions|functions]] there are before spending time on writing a script, just to find out it is ''not'' possible in the end.


Depending on your answer for these questions, you may want to rethink your approach.
