I am trying to make a vehicle selection system in ue4 with blueprints.
I have followed this video.
Below are the screenshots of my code.
screenshot1 and
screenshot2
firstly I tried to figure out what is happening to my code then I came to know that the cast was not succedding and hence the car is being spawned but not posessed.
please help me by listing some reasons that may be responsible for this.
if you want any info so I have given the link of the video which I have used to make the system.
thanks in advance.
I found the answer

I am using a Oculus DK2 (v0.8) and OSVR SDK. I'm having a problem getting the HMD to run/display anything.
The Oculus samples and the OSVR samples do work however, so the osvr_server seems to run fine.
My application itself renders a test scene just fine when not using a HMD.
I tried two approaches:
First, just creating a osvr context and creating a DisplayConfig object. This seems to work, but DisplayConfig::checkStartup() fails (I do this in a loop, calling update on the context when the checkStartup call is failing). I used the OpenGLSample.cpp as a guide for this
Second, I tried using a RenderManager, but the call to createRenderManager results in a crash within the RenderManager.dll. I get the same crash wether I create the graphics lib object myself or if I let the library create it.
I am quite stuck now, since the demos and examples do work, I have no idea where to look for the error on my side. Creating the context works, querying interfaces as well, but the crash with createRenderManager is beyond me.
Does anyone have any hints or ideas what the problem could possibly be?
Regards and thanks in advance

RenderManager should not crash during open. There have been a couple of bug fixes recently to avoid that happening, and the latest RenderManager binaries, libraries and header files are available with the SDK download from http://osvr.github.io/using/ along with updated copies of the example programs.
When something goes wrong in RenderManager, it usually reports that to standard error. We're moving that to a logging interface, but for now it should show up on the console. Posting an output of that as an issue at https://github.com/sensics/OSVR-RenderManager/issues is a good way to let the developers know that there is a problem. Of course, providing the same sort of information you provided here will be helpful as well.
Does anyone know any details on the underlying eclipse builder that sends jobs to the compiler and get its report? and how to tap to it? The level of abstraction that the builder extension offers is too high and the information insufficient. So I implemented an IResourceChangeListener and played with the ResourceDelta in order to get the messages from an IMarker. It works perfectly, however I realized the message is just returning a string. So my question is, how do I do in order to get the type/reference of the object where the error is, what type of error, what class it should belongs to and all available info.
Thanks.
Have you looked at the builder documentation?
And there is also This article by John.
I think between those two and looking at the code you will find everything you need to know.
i am trying to use the goTo function to switch between different divs.
but in the function goTo(id,animation)
it is not going to that id.
Can anyone please help me with this problem.
Thanks,
Devan
This is difficult to diagnose without looking at your code. I have a few ideas, but it would be best if you were to share the problematic section of your code for others to investigate.
A few questions/ideas:
1) Check to ensure you have not used the same div ID more than once.
2) Have you been able to successfully use the goTo function at all?
3) Can you create a basic HTML page that uses this function successfully?
4) What version of jQTouch are you using? Does the goTo function work once, and then freeze every time afterwards? I reported a bug regarding this behavior a while ago. Not sure if it's been resolved yet, but you could see if an older version of jQTouch might help.
Again, without examples of your code... I'm taking wild guesses. Consider sharing the problematic section and someone might be able to pinpoint the issue.
Don't put animation, without animation worked for me...
eg..
jQT.goTo('#rest');
I want to write a simple media player which displays lyrics that are retrieved from the web.
I know once LyricWiki was such a source, but now no longer exists.
Does a new API or source for lyrics exist that I can use ?
When I do get the lyrics, how do I sync them with song ?
I know the MPMediaItem class has the MPMediaItemPropertyLyrics but this is cleary not enough for me cause this is only for songs from Itunes and not all of them have lyrics available.
I would appreciate any help or links that can I use to sort this issue.
A little Googling and I found a few options that might solve your problem:
First, LyricWiki does still exist. It's moved to lyrics.wikia.com. It seems that their API, however crops the lyrics, due to licensing.
LyricsFly
ChartLyrics. Looks the most promising to me, though I haven't actually tried any of the services myself (yet).
I'd like to hear which works for you the best, should any of them.
https://developer.musixmatch.com
it's an Official and Authorized lyrics api
The synced lyrics api are expensive. following do the job but dont know how expensive they are.

I found Yoshimasa Niwa's article about blob detection here:
http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en
And something on realtime face detection here:
http://www.morethantechnical.com/2009/08/09/near-realtime-face-detection-on-the-iphone-w-opencv-port-wcodevideo/
But what I really want to do is realtime blob detection (like http://www.youtube.com/watch?v=LIgsVoCXTXM) using the iPhone 4 camera.
I can find the headers for CvBlobDetector in cvvidsurv.hpp. But trying to use that without modification is not the right thing to do.
How do I get CvBlobDetector to work? Or is there an alternate solution?
Make sure you've followed the instructions to use it properly:

One of the alternative solutions i used and it works good is:
