Description:: Selects an element from an Array, same as select command for arrays, but has higher precedence.
ⓘ
# has higher precedence than all binary operators, but it has lower precedence than unary operators (see Example 3).
Groups:: Variables

Example 1:: Copy
[1, 2, 3, 4] # 2; // result is 3
Example 2:: Copy
getPosASL player # 2; // result is Z component of player's position
Example 3:: Copy
// 'getPosASL' is unary; '#' and '+' are binary; precedence is: 'getPosASL' > '#' > '+' getPosASL player # 2 + 1; // equivalent to (getPosASL player # 2) + 1, not (getPosASL player)#(2+1)

: Although not alternative syntax, the below notations work as expected:
Copy
["A", "B", "C"] # 1; // B ["A", "B", "C"] #1; // B ["A", "B", "C"]#1; // B ["A", "B", ["C", "D"]]#2#0; // C

: Here is an example of what higher precedence means:
Copy
[1, 2, 3, 4] select 2 / 2; // divides 2 with 2, therefore selects the second element at index 1, result = 2 [1, 2, 3, 4] select (2 / 2); // same result with brackets [1, 2, 3, 4] # 2 / 2; // selects third element, then divides by 2 = 1.5 ([1, 2, 3, 4] # 2) / 2; // same result with brackets

This operator can not be used in conjunction with the #define preprocessor.

Copy
#define SEL_ERR [0,1,2]#0; // error #define SEL_NOERR [0,1,2] select 0; // works

: Beware new-lines when using this operator. I suspect the preprocessor to fail. The following code will not compile without throwing an error:
Copy
[0] # 0;
