| • string | source | |||
| • string | pattern |
If pattern is not found in source, -1 is returned.
The index of the first character in the string is 0
Caveats
- Performs a literal match.
- Wildcards and RegEx are not supported.
Examples
Useful Snippets
An easy way to see if a string exists in another string...
if(~llSubStringIndex(myString, str))
{//it exists
//This works because ~(-1) == 0
//It saves bytecode and is faster then doing != -1
//(It's also significantly less readable (unless you include the comments)
// and most developers I know will advice against these kind of practices. -OddesE Oh)
