addCameraSceneNodeMaya

Hi,

Got Irrlicht integrated into my project in 2 days - its really good.

But the Maya camera node has a problem. When you try to zoom in, it stops zooming at a certain point, and flips back when you release the middle mouse.

Also the setPosition() doesnt work on the Maya camera - I looked inside and thats because the Maya keeps its own position value seperated from the scene node position, and there doesnt seem to be any interface to the Maya node position.

Ok I understand that the zooming is meant to stop - I get it.

I made a fix in CSceneNodeAnimatorCameraMaya::animateNode, to stop the zooming snapping back:

Code: Select all

   const f32 targetMinDistance = 0.1f;   //Moved this here
   if ( (isMouseKeyDown(0) && isMouseKeyDown(2)) || isMouseKeyDown(1) )
   {
      if (!Zooming)
      {
         ZoomStart = MousePos;
         Zooming = true;
         nZoom = CurrentZoom;
      }
      else
      {
         //const f32 targetMinDistance = 0.1f;
         nZoom += (ZoomStart.X - MousePos.X) * ZoomSpeed;

         if (nZoom < targetMinDistance) // jox: fixed bug: bounce back when zooming to close
            nZoom = targetMinDistance;
      }
   }
   else if (Zooming)
   {
      const f32 old = CurrentZoom;
      CurrentZoom = CurrentZoom + (ZoomStart.X - MousePos.X ) * ZoomSpeed;
      nZoom = CurrentZoom;

      //if (nZoom < 0)
      //   nZoom = CurrentZoom = old;
      if (nZoom < targetMinDistance)                  //Fix to stop zoom snapping back
         nZoom = CurrentZoom = targetMinDistance;
      Zooming = false;
   }
