How to make .net regex start searching from the end of the last match?

l'm new to Regex. Currently I'm trying to get all consequences of symbols without spaces from a string and to get null when they end.

var pattern:Regex=new Regex("[^ ]+");
    var s:String;
    for(var i:int=0;i<10;++i)//10 is for debugging because otherwise it will never end
    {
        s=pattern.Match("speed movement_vector Rigidbody walk_mode").Value;
        if(!s)
            break;
        Debug.Log(s);
    }

This finds only 'speed'.

In this article I've found G command which finds occurrence exactly after the last match, i.e. it cannot skip spacebar.

Besides, I don't understand it, because my pattern

var pattern:Regex=new Regex("\G\[^ ]+");

only throws errors about "Unexpected character G".

The reason for this is because \ is an escape character in both unityscript and regex. To fix this, add another \ before the first one (the second one should be unnecessary):

var pattern:Regex=new Regex("\\G[^ ]+");
