function
Function syntax
integer llOrd(
  1. string val,// Source string.
  2. integer index// Codepoint index of the character to convert. Supports negative indexing.
);
Returns
integer
Energy
10

Calculate the ordinal value for a character in a string.

The returned value is the UTF-32 value of the character at the specified index. If index is outside the bounds of the string, this function returns 0.

How to use
integer result = llOrd("", 0);

Caveats

Section titled “Caveats”
  • Characters in the surrogate range ("\u{D800}" - "\u{0xDFFF}") will return 0x3F = 63. This might not be observable on LSL, only SLua. SLua’s equivalent utf8.codepoint instead raises an error "invalid UTF-8 code" in this situation.
