Deleting a single point in a polygonal hotspot

Hi,

I am writing a tool to draw on a krpano viewer. Part of this is dynamically creating polygonal hotspots, much like the example given in the "addhotspot" documentation.

Source code

addhotspot(polyspot);
set(hotspot[polyspot].fillalpha, 0.25);
set(hotspot[polyspot].borderalpha, 0.50);
set(hotspot[polyspot].onclick, removehotspot(polyspot) );
set(hotspot[polyspot].point[0].ath,-10);
set(hotspot[polyspot].point[0].atv,-10);
set(hotspot[polyspot].point[1].ath,-10);
set(hotspot[polyspot].point[1].atv,+10);
set(hotspot[polyspot].point[2].ath,+10);
set(hotspot[polyspot].point[2].atv,+10);
set(hotspot[polyspot].point[3].ath,+10);
set(hotspot[polyspot].point[3].atv,-10);


The problem is that I cannot delete any of these points — how do I delete a single point? Is this even possible?

EDIT: things I have tried (that do not work):

Source code

removehotspot(hotspot[polyspot].point[3])
delete(hotspot[polyspot].point[3])
delete(hotspot[polyspot].point['n3']

I don't think you can remove a single point of polyhotspot, but I guess there are other options... Like giving the same position as the next or previous point...

That would not help. My goal is to be able to delete any single added point.

Will I simply have to delete the whole hotspot and re-render it? That would be reasonably trivial.

I remember the "removearrayitem()" action from documentation. And here's the answer to your question, I hope:

programmatically remove points from polygonal hotspot

Hi Alexey,

Yes. That works perfectly!

Do note that you must call "updatescreen()" before this change will be graphically represented.
