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 and any non-zero integer is considered true.
    //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)
}
