get variable don't work

dimazz

I took the old xml (krpano version 1.16) and try to make it work with krpano version 1.19-pr8. All works, except that the variable (viewdir), which I use to determine the view direction is not taken from the hotspot.
What could be the problem ?

Code

<style name="skin_hotspotstyle" url="img/hotspot.png" scale="0.3" edge="center" oy="0"
	       distorted="true"
	      onclick="if(linkedscene, tween(scale,0.25,0.5); tween(oy,-20,0.5); tween(alpha,0,0.5); lookto(get(ath),0);
		   			loadscene(get(linkedscene),null, MERGE ,ZOOMBLEND(1,2)););
					lookat(get(viewdir),0);"
		  onhover="tween(scale,0.35,0.1);"
		  onout="tween(scale,0.3,0.1)"
	       />

Code

<scene name="scene_01" title="01" onstart="activatespot(point01,79.48)" thumburl="panos/01.tiles/thumb.jpg" lat="" lng="" heading="">


		<view hlookat="0" vlookat="0" fovtype="MFOV" fov="120" maxpixelzoom="2.0" fovmin="70" fovmax="140" limitview="auto" />


		<preview url="panos/01.tiles/preview.jpg" />


		<image>
			<cube url="panos/01.tiles/pano_%s.jpg" />
			<mobile>
				<cube url="panos/01.tiles/mobile_%s.jpg" />
			</mobile>
		</image>


		<!-- place your scene hotspots here -->
		<hotspot name="spot1" style="skin_hotspotstyle" viewdir="189" ath="-140.654" atv="38.671" linkedscene="scene_02" />
		<hotspot name="spot2" style="skin_hotspotstyle" viewdir="180" ath="-25.030" atv="40.703" linkedscene="scene_13" />


	</scene>

Hi)

Try this:

Code

lookat(get(hotspot[get(name)].viewdir),0);

Maybe it helps.

Hi,

this doesn't work (anymore) because after 'loadscene' the hotspot from the previous scene would be already removed (unless it was defined with keep=true) and so that hotspot and its 'viewdir' attribute aren't available anymore.

In older versions this was working because of a bug (a memory leak), there the hotspot wasn't fully removed.

A way to get this working would be getting the 'viewdir' before the loadscene call, e.g. into some temporary variable and then using that variable later instead.

E.g. here an example:

Code

copy(hs_viewdir, viewdir);
loadscene(...);
lookat(get(hs_viewdir),0);"

Btw - have also a look into the vtourskin.xml from the latest version, it has a similar functionality already implemented - there each hotspot could contain a 'linkedscene_lookat' attribute which would define the looking direction for the linked scene.

Best regards,
Klaus
