calc: and get: in text layer html

zabelin

hi there
looks like the code doesn't work anymore in krpano 1.20.9

Code

...
html="get:scene[get(xml.scene)].title"
...

returns nothing

trying to calc the title of a tour and the scene's title

Code

...
html="calc:'[i]' + title + '[/i][br]' + get:scene[get(xml.scene)].title"
...

returns:
"ERROR: Invalid expression: '' + title + '[br]' + get:scene[get(xml.scene)].title"

by the way

Code

<events onkeydown="showlog(); trace(get(scene[get(xml.scene)].title));" />

Code

html="calc:'[i]' + title + '[/i]'"

works fine

any advice, please

you cant combine calc: and get: in one expression
i guess correct would be:

Code

html="calc:'[i]' + title + '[/i][br]' + scene[get(xml.scene)].title"

but i also think when the xml gets parsed xml.scene is not defined, yet
you could test that by checking if this works:

Code

html="calc:'[i]' + title + '[/i][br]' + scene[existing_scene_name].title"

xml.scene is dynamic and calc: / get: is evaluated only once on init
to do this for every scene you'd need to set up an event action

indexofrefraction thank you

Understand now.
So yep events are great for dynamically changing texts.
In the end, came up with:

Code

<events name="add_event" keep="true"
    onnewscene="set_scene_description();"
/>
<action name="set_scene_description">
    set(scene_title, get(scene[get(xml.scene)].title));
    set(scene_category, get(scene[get(xml.scene)].category));
    set(layer[scene_description].html, calc('[i]' + title + '[/i][br][strong]' + scene_category + ' — ' + scene_title + '[/strong]'));
</action>
