Despite your help, I'm not yet up to speed. I'm having trouble positioning my control relative to
GUILD_HOME_SCENE. It is quite clearly being positioned relative to the main window. I suspect that is because my container control is an instance of TopLevelControl, which I'm sure isn't right, but it is the only thing the tutorials suggest, and I can't find any indication of what else it could be.
Code:
<GuiXml>
<Controls>
<TopLevelControl name="MyControl" hidden="true">
<Dimensions x="200" y="200" />
<Anchor point="BOTTOM" relativeTo="$(parent)" relativePoint="BOTTOM" />
<Controls>
... etc
</Controls>
</TopLevelControl>
</Controls>
</GuiXml>
