Arrays

An array represents an indexed collection of elements of the same type (called the base type). You can work with any element directly via its index. An index numeration begins with a zero. Arrays are supported in San Andreas, LCS and VCS.
General Syntax
San Andreas:
<array name>(<index var name>,<size><type>)
$index = 0
$array($index,10i) = 1
<array name>: local or global variable
<index var name>: any variable containing an index of the element to read or write
<size>: a value between 1 and 255 (inclusive)
<type>: one of characters i f s v:
Letter
Item Type
Item Size (bytes)
i
integer
4
f
float
4
s
string
8
v
string
16
Liberty City Stories, Vice City Stories:
<array name>(<index var name>,<size>)
In LCS, VCS, array elements are only 4 bytes in length. Therefore, there is no need in type declaration.
$index = 0
$array($index,10) = 1
Array Declaration
Arrays can be declared using the VAR..END construct:
var
   <array name>: array <size> of <type>
end
var
    $FloatArray: array 10 of Float
end
Accessing array elements after declaration
After declaring an array you can work access its elements using square brackets:
var
    $FloatArray: array 10 of Float
end
$index = 1
$FloatArray[$index] += 100.0
Using constant indexes
You can use positive integer numbers and zero to access a particular array element:
var
    $FloatArray: array 10 of Float
end
$FloatArray[1] += 100.0
Elements of an array containing string literals can be accessed with string variables:
// initializing first three elements of the $strings array
s$strings[0] = 'str1'
s$strings[1] = 'str2'
s$strings[2] = 'str3'
An array can be declared as a collection of class instances:
var
  $players: array 2 of Player
end
$players[0].Build
By default in the GTA SA edit mode, the disassembler prints array elements with the numbers as indexes. The same feature is available in LCS and VCS but is disabled by default. You can turn this feature on and off using the debug option CONSTANT_INDEXES.
