  • Hi,

    I'm working towards implementing a dialog system utilizing xml files generated by the Flamewind Conversation Editor (@nwvault- free, standalone) and was curious as to the best way forward, in a general sense. Below is a sample conversation output xml.

    I've taken a look at the dialog info linked in the "How do I?" FAQ, but since this editor is free and easy to use, I figured to work from it to employ a system that others might be able to implement, without an encumbered workflow.

    FWIW, I see the npc text as a text or (uneditable) textbox object, and the player replies as listbox object items (only way i see to add/subtract reply options).

    My questions are:

    1. Should I parse the xml as is within events (pulling text and resolving conditions/actions directly from its content), or should I load its content into another form(s) (array and/or otherwise) and use that/those to resolve events? I'm not clear on the advantages of one over another or whether the xml would readily conform to a better format. Also, My personal implementation would be on a desktop browser, so I suppose I'm less concerned about cross-functionality at the moment, but...

    2. Would a transformation (XSLT) of the output xml (into another xml) be wise before attempting #1? It's not exactly the most followable xml. Idk if transforming would help coding/XPath expressing.

    Here is the code

    <?xml version="1.0" encoding="utf-8"?>
    <Conversation xmlns:xsi="can't post urls" xmlns:xsd="can't post urls">
      <subNodes>

    About the xml:

    A couple elements are superfluous (as a standalone application), such as "<additionalData />" and "<infoObjects />". They're always empty.

    An "idNum" value of 0 means that an element is copied (as a link) from another element (whose idNum is expressed in the "linkTo" value)

    The comment element provides an opportunity to insert condition|action parameters

    Any general thoughts/suggestions would be appreciated. I've begun working on it, and I'll post my capx progress once I've locked onto a directin. Thanks!
