This section covers what a script is and different ways to execute it with and without cheats.

What is a Script? When programmers refer to a script in the ArmA realm they are referring to a .sqf file. A Script is a plain text file that can be edited using a program like notepad. SQF is another, more definite, term for a Script. Every script follows the same Syntax. A Syntax is the grammar for a programming language. If a script is not following the correct Syntax then the code will create an error in game (Note: Errors can be viewed with the -ShowScriptErrors parameter in game).

 

Code:

---

/* Hello World Script
  Created By Lystic
  On September 17th
  2014
*/
hint 'Hello World';

---

 

Code:

---

/* Kill player script
  Created By Lystic
  On September 17th
  2014
*/
player setDamage 1;

---

How are Scripts Executed? Scripts can be executed through: Mission files, Script Executers, PBOs, In Game Debug Monitors, and Other Scripts. A Script Executer is an external program that executes a selected script in game. Script Executers are generally perceived as Hacks or Cheats, but in some cases these can be used to improve security and/or test new features in game.

 

This section covers the basics to programming in the scripting language

Data Type -- Covered on Quiz

This section covers the basics to programming including how to make your own hello world script, different data types, functions, parameters, and operators.

What is a datatype? DataTypes are different kinds of values such as: NUMBER, STRING, BOOLEAN(true/false).

What are Variables? Variables are Name placeholders for DataTypes.
What is a LOCAL Variable? These variables are LOCAL to the block. Check the example to learn more!
What is a GLOBAL Variable (use these if you are new to scripting)? These variables are GLOBAL to every block. Check example to learn more!
What is a Block? A block is a chunk of scripting code grouped together. (Starts and Ends with {}).

 

Code:

---

_variable = 2;

---

 

Code:

---

//Local Variable (this code gives an error)
_function = {
  _localVariable = 2; //creates a local variable within the function block
};
call _function; //executes the function block
hint str _localVariable; //error _localVariable is not defined in this block!

---

 

Code:

---

//Global Variable Example
_function = {
    globalVariable = 2;
};
call _function;
hint str globalVariable; //no error. Outputs '2'

---

Scripts are executed one Statement at a time. A Statement is either a Value Assignment, Control Structure or Command. What is a value assignment? a Value Assignment is when a Variable is given a value. A Control Structure is either an If-Statement, While-Loop, Switch-Statement, ForEach-Loop, or For-Loop. Loops are Control Structures that repeat the code within their block until their conditional statement is false. A Command is a word that represents some kind of functionality in game.

 

Code:

---

//Loop Example
while{true} do {
    hint 'Infinite Loop';
};

---

 

Code:

---

//If Example
_value = 2;
if(_value == 2) then {
    hint '_value is 2';
};

---

 

Code:

---

//Switch Statement
_value = 4;
switch(_value) do {
    case 1: {hint 'Value is 1';};
    case 4: {hint 'Value is 4';};
};

---

 

Code:

---

//For Loop
for "_i" from 1 to 4 do {
    hint 'I am repeating 4 times!';
};

---

 

Code:

---

//ForEach Loop
_array = [1,2,3];
{
    hint str(_x);
} forEach _array;

---

Coding on your own: Now I want to see you create a script on your own. This script is supposed to output the words 'Hello World' onto screen (in any fashion).

 

Code:

---

//these are only a few of the ways
hint 'hello world';
cutText 'hello world';
titleText 'hello world';
systemChat 'hello world';

---

Coding on your own: Expand this script to heal the player and tell the user that they have been healed.

Code:

---

//Check https://community.bistudio.com/wiki/setDamage for setDamage info
player setDamage 1;


---

 

Code:

---

//this is only one example (there are more ways to do this!)
player setDamage 0;
hint 'you have been healed!';

---

Coding on your own: Make the player fly into the sky and notify the users that they are now a rocket ship.

 

1) use setVelocity (look at BIWiki)

 

Code:

---

//makes player launch into sky
player setVelocity [0,0,100];

---

After these two sections, if you can create those basic scripts on your own (section 2) then you are on your path to becoming a scripter!
