I am trying to perform some math using stagewidth, stageheight and the hlookat of a particular scene. To help me see what I am doing I have included a temporary textfield plugin to display the results of the calculations and passing it the variables in an onresize event, e.g.

<events name="showvalues" keep="true"
onresize="
div(skin_settings.windowratio,stagewidth,stageheight);
txtadd(plugin[stagesize].html,[p],get(stagewidth),[br],get(stageheight),[br],get(skin_settings.windowratio),[br],get(scene[scene_name].view.hlookat) );"
/>

This works for the stagewidth, stageheight and windowratio variables,which all display correctly, but the hlookat displays as 'null', so I must have the syntax wrong for getting that variable, but I can't figure it out. If I substitute 'title' for 'view.hlookat' the scene's title is shown correctly, so I guess it must be something to do with the way I am trying to access the scene's view element.

Can anyone advise, please?

Thanks, Tuur. I have never used calc: but I will from now on - it looks so much simpler than my way!

However, and I'm sorry I did not make this clear in my original post, I am trying to get to the hlookat value of a scene other than the current one, as declared in the scene's <view parameters, Then I could set the hlookat value according to the ratio of stagewidth to stageheight so that the user always sees a pleasing composition when the scene opens. Thus the hlookat value when the scene first loads would be different if the user is holding their tablet or phone in a vertical orientation rather than horizontal.

Just getting view.hlookat shows the current value for the current scene - hence my attempt to use get(scene[scene_name].view.hlookat) which just returns a null value. If as a test I use get(scene[scene-name].title) I do indeed see the scene's title string, but I can't get down to the scene's <view parameters. Obviously I have got the syntax wrong - but I am struggling to see why.
