Creating a custom source

You can create custom sources using the ISource interface.

The following example shows how to create a source that generates a random number. This could then be combined with a choose Formatter to produce different random responses.

[Serializable]
public class RandomValueSource : ISource
{
    public int min = 1;
    public int max = 5;

    public string selector = "random";

    public bool TryEvaluateSelector(ISelectorInfo selectorInfo)
    {
        if (selectorInfo.SelectorText != selector)
            return false;

        selectorInfo.Result = Random.Range(min, max);
        return true;
    }
}

Example Smart String	Result
{random:choose(1|2|3}:Hello|Greetings|Welcome|Hi}!	Welcome!
