Collision detection: interaction between from and into?

Scripting Issues

  1. You can’t search for Ralph’s right eye since Ralph is an animated character. Basically, anything under tag can not be search for.
  2. Take a deep look at this part :
      if self.queue.getNumEntries() > 0:
         self.queue.sortEntries()
         self.pickedObj=self.queue.getEntry(0).getIntoNodePath()

         parent=self.pickedObj.getParent()
         self.pickedObj=None

         while parent != render:
            if parent.getTag('pickable')=='true':
               self.pickedObj=parent
               return parent
            else:
               parent=parent.getParent()

In case your self.pickedObj (entry[0]) is already a pickable node, you would miss it silently. So first you have to check if it’s already a pickable one.

      if self.queue.getNumEntries() > 0:
         self.queue.sortEntries()
         self.pickedObj=self.queue.getEntry(0).getIntoNodePath()

         if self.pickedObj.getTag('pickable')=='true':
            return self.pickedObj

         parent=self.pickedObj.getParent()
         self.pickedObj=None

         while parent != render:
            if parent.getTag('pickable')=='true':
               self.pickedObj=parent
               return parent
            else:
               parent=parent.getParent()
