Glue channels - how to preload sounds and images?

[davem2007]

I'm having trouble getting images and sounds to load quickly. Have made file sizes small but
some preloading would help.Should I do this in javascript?
thanks dave

Hi Stefan

This looks promising ... but not sure where to add it

 <parameters>
        <parameter key="cachedFile1">http://yourserver.com/yourmodel.zip</parameter>
        <parameter key="cachedFile2">http://yourserver.com/sound.mp3</parameter>
    </parameters>

Can you please give me an example of how I would use this? Would I add this code into my arelGLUE5.js or search.php?

thanks again, dave

Hi Dave,

I put these lines in the search.php: This adds a parameter to my object with the ID "weapon"

$oObject->addParameter("sound", "http://www.....mp3");
ArelXMLHelper::outputObject($oObject);

And this one in the arel.js to pick the sound in the parameter:
arel.Media.startSound(arel.Scene.getObject("weapon").getParameter("sound"));

Hope this will help you.

Hi cristin

Thanks for coming to my rescue once again! Cant get it working yet, am not sure if I'm using the ID properly, any ideas...??

In my search.php:

$oObject = ArelXMLHelper::createGLUEModel3DFromImage(

"image-robin_cell_floor",

WWW_ROOT . "/resources/robin_cell_floor.png", 

array(10, -280, 20), //translation 

array(2,4,4), //scale

new ArelRotation(ArelRotation::ROTATION_EULERDEG, array(-90,-30,0)), //rotation

4 //CoordinateSystemID)

);

// preloading sounds

$oObject->addParameter("sound_jail_door", "http://davemiller.org/ar/sounds/jail_door.mp3");

//output the object

ArelXMLHelper::outputObject($oObject);

-----

In my arelGLUE5.js:

arel.Media.startSound(arel.Scene.getObject("4").getParameter("sound_jail_door"));
