unity3d - Vuforia Cloud Recognition not working properly for the first few detection in Unity -


i making app using vuforia , unity. have implemented vuforia cloud recognition in project , working 1 issue.

what doing right is:

  1. added markers vuforia cloud service.
  2. in metadata of marker have added url of asset bundle download game objects render on marker after detection.
  3. after game object downloaded, fetch names of prefabs downloaded asset bundle , show them in list user select game object want display.
  4. when user select item list instantiate prefab , make child of imagetarget.

this how this.

   public void onlistitemclick(gameobject namegameobject)     {         string name = namegameobject.transform.parent.name.tolower();          objecttoaugment = (gameobject) bundle.loadasset(name);          if (parentobject.transform.childcount>=1 || parentobject.transform.childcount==0)         {             if (parentobject.transform.childcount >= 1)             {                 destroy(parentobject.transform.getchild(0).gameobject);             }              objecttoaugment = instantiate(objecttoaugment, parentobject.transform);             objecttoaugment.transform.localrotation = new quaternion(0, 90, 0, 1);             objecttoaugment.transform.localposition = new vector3(0, 0.1f, 0);             objecttoaugment.transform.localscale = new vector3(0.1f, 0.1f, 0.1f);             objecttoaugment.addcomponent<leanscale>().requiredfingercount = 2;             objecttoaugment.addcomponent<leantranslate>().requiredfingercount = 1;          } }

this make child of image target instantiated object doesn't follow vuforia image target behaviors.

for eg. instantiated object doesn't move when image target moved, stays @ same place instantiated.and during time vuforia events tracking lost , tracking found not called @ all.

however, if remove/show image target few times camera fov, starts recognizing image target , model shows @ correct position , scripts methods called after that.

i unable pinpoint exact issue here.

edit:

this seems bug vuforia cloud services. days works while other days start giving these problems. experienced ?

resizing Telegram inline keyboard -

telegram's inline keyboard great feature lots of different use cases. inline buttons added list of items this: inline_keyboard = [[inlinekeyboardbutton(text="button", callback_data="button"), inlinekeyboardbutton(text="reset",callback_data="reset")]] inline_keyboard_markup = inlinekeyboardmarkup(inline_keyboard) update.message.reply_text("hi", reply_markup=inline_keyboard_markup) the above code adds 2 buttons each half width of chat screen. i know the normal keyboard button there resize_keyboard parameter somehow can used. my question is there way resize inline buttons ? example make full width or quarter width. unfortunately, can't now. :( you can suggest @botsupport , might add feature next version.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
