[solved] drag fonction bug on mobile

Hi !
On mobile, the layer don't take the touch position in real time , and stop !

desktop it's works ... any idea ?

<layer name="test" type="text" html="test-drag" edge="center" align="topleft" bg="true" bgcapture="false" capture="true" handcursor="true" selectable="true"
height="20" width="100" vcenter="true" zorder="100" parent="blockFp"
ondown="dragTest(get(name),true);"
onup="dragTest(get(name),false);"

/>

<action name="dragTest" scope="local" args="layerhp,boolean">
if(boolean,
screentolayer(blockFp,mouse.stagex,mouse.stagey,lx,ly);
set(layer[get(layerhp)].x,get(lx));
set(layer[get(layerhp)].y,get(ly));

delayedcall(testFollow,0.01,
dragTest(get(layerhp),true);
);
,
stopdelayedcall(testFollow);
);
</action>

same issue with asyncloop:

<action name="dragTest" scope="local" args="layerhp">
showlog();
asyncloop(global.dragtestlayer,
screentolayer(blockFp,mouse.stagex,mouse.stagey,lx,ly);
set(layer[get(layerhp)].x,get(lx));
set(layer[get(layerhp)].y,get(ly));
);
</action>

on mobile it return the x/y pos of blockFp and stop

layer blockFp is parent="STAGE" and is outside area

ok that's it, if block not parent="STAGE" it works good... but i need parent="STAGE" any solution ?

added in js

function doTouch(e) {    e.preventDefault();
    var touch = e.touches[0];


    krpano.set('touchX',touch.screenX);
    krpano.set('touchY',touch.screenY);
}


krpano.addEventListener('touchstart', function(e) {doTouch(e);}, false);
krpano.addEventListener('touchmove', function(e) {doTouch(e);}, false);

and do this on my drag function :

<action name="HpFollowMouse" scope="local" args="layerhp, layerplan, rl,boolean">   if(boolean,
       if(device.desktop,
          screentolayer(get(layerplan),mouse.stagex,mouse.stagey,lx,ly);
          ,
          screentolayer(get(layerplan),touchX,touchY,lx,ly);
       );
       set(layer[get(layerhp)].x,get(lx));
       set(layer[get(layerhp)].y,get(ly));
       if(rl,
        set(plugin[radar].x,get(lx));
        set(plugin[radar].y,get(ly));
       );


   delayedcall(HpFpFollow,0.01,
      HpFollowMouse(get(layerhp),get(layerplan),get(rl),true);
   );
   ,
   stopdelayedcall(HpFpFollow);
  );
</action>

because the mouse position only work inside area and not outside area + (layer parent = stage) on mobile :)
