<div>Thanks Julian.<br><br>Yes, this does work;<br><br>if (interaction.XMLElement.childNodes[2].clip().correct == undefined) {<br>interaction.XMLElement.childNodes[2].clip().CreateAttribute['correct'];<br>interaction.XMLElement.childNodes[2].clip().correct = 0;<br>}<br><br>But I'll use the node syntax you suggested:<br><br>node.attributes.myNewAttribute = "value";<br><br><br><br>

<div dir="ltr"><font size="2" color="#000000" face="Arial">If you are building the file at runtime (I think you are) then, yes, my preferred way is to work with the XML. It is then parsed and the file is created. There may be a danger that by setting properties directly, you miss something else the code does when initalising icons. So, yes, for example, you could set the correct property on a response movieclip, but if the engine also does something else at that point (like add the response to the array) then it won't happen.</font></div>

<div dir="ltr"><font face="Arial">I think, in the case of 'correct' you can set it at runtime, because I seem to remember building it to work in a dynamic way. That may not be the case for every movieclip property that has a corresponding xml attribute.</font></div>
