[@ravimaru8284]

Love your honesty & humor, Mate. Thank you for your time & work i really appreciate it alot. God bless you

[@MatthewHallberg]

+Ravi Maru thanks so much man! Means a lot.

[@dheamiradikna6178]

can you re-send link? The link is broken, thanks

[@PaulJosephHogan]

Great tutorial, will use it as a base to start playing with this markerless approach, thanks for sharing. Although one flaw is that as it does not know about the surroundings if you open the app in a room/area with obstacles the ships fly through them. Might see how this works with the Structure Sensor

[@MatthewHallberg]

Yeah something like project Tango would work much better with this, can't wait till I can play with one.

[@henryqng]

Matthew, This is a very nice tutorial. You made it so easy to follow and fun. Thanks for creating this tutorial!

[@MatthewHallberg]

Anytime! Thanks for watching.

[@jiripavlicek2043]

Well, it doesn't work. I can see the camera texture but there are no enemies around the camera. SOLVED - My phone doesn't have gyroscope. It works on phones with gyro

After 4 years. Here we are. Starting it.

[@eugenelee8302]

Hey Mathew! thank you so much for this tutorial! i'm having some trouble and i'm hoping you can help me. I'm halfway thu the tutorial, xcode builds out just fine, with no errors (on an iphone 8 btw ) but i can't see the spaceship anywhere. When the app opens.. i get a request to use the camera but when the camera turns on there is no spaceship to be found. any idea what i am doing wrong or why the space ship is hidden?

[@char2681]

Hi Matthew - Great tutorial and I'm loving your videos so far they're really fun and great learning tools. Following this tutorial, I find that when I deploy to my Galaxy S8+, my surroundings come out great and I can see around me. Not the best picture but it works. My problem is that the ship / models don't show up on the phone? It does on my Mac, but not when I deploy to the phone. Everything else is working fine. Any fixes for this? I scanned the comments but no joy! :(

The video is really fantastic. I got one query..everything is working fine except that when playing it on android phone I can see environment through device only if i tilt the camera down and at times side ways ..if I tilt the camera up then it shows complete black ......though Spaceships can be seen. Please help....(Struggling to fix it.)

[@ashish3984]

Excellent video helped me alot Matthew just wanted to know can we do a virtual button in this just like vuforia

[@MatthewHallberg]

Good question, I don't think we can easily. The project would need some time of image processing. I do plan to experiment with openCV here soon, so that might be the answer. Even so, we would probably not be able to do buttons without some type of image or marker.

[@xternalcreations3032]

Thanks man, really I suck though, theres so much to learn its insane.

MatthewHallberg Nah you're good. There's is so much to learn. My problem is that I try to learn too many things at once. I need to get past that somehow

[@MatthewHallberg]

dude...story of my life. I want to know everything, and I get jealous when people know something I don't, it's the worst. It leads my down a path of knowing only a little about a lot of different things which isn't very conducive to making money. It seems the people that make the most money are experts in a very specific field, so it's not looking too good for my financial future lol.

[@brandondavis4598]

MatthewHallberg haha wow, I'm exactly the same way. there must be some value to being well rounded for us to work with though lol

[@DearStephanieX]

[@prashanthputta8664]

Just nailed it MatthewHallberg, thanks a lot and please continue the great work. And a small doubt, can you please give more clarity regarding the plane co-ordinates that are to be used for Andriod, I have tried a few but my camera view is always inverted.

[@MatthewHallberg]

Thanks dude. I am not 100% sure because I don't have a good Android phone right now but you should just be able to rotate and flip that texture until it looks right when you build out. I don't know what coordinates for sure so you will probably just have to try a few different orientations.

[@yohaantavadia4251]

Probably make a world space UI and put the script on there.

Sorry I was thinking VR, make a screen space canvas I mean. Actually there should already be a screen space canvas, because thats what the cockpit image is on.

[@MatthewHallberg]

For a persistent model in the world you are going to need a fiducial marker for that. I would just use Vuforia for what you are trying to do. That way you can move around in the world and the 3d model will be stuck to wherever the marker is.

I never tried this on Android so I am not 100% sure on how to do it but it might be a combination of rotating the x and z to get the desired rotation but you will just have to play with it and see what works.

hmm no idea...do you have the scale of the ship the same as the tutorial and did you copy and paste the exact same code or did you modify it?

[@garethconway970]

I have fixed it by deleting duplicate space ships and redoing them. May be they were colliding. Great tutorial though, enjoyed it. Have you tried EasyAR? It's a free Augmented Reality SDK with a unity plugin. Lets you have an app without the Vuforia logo. Thanks again

[@shaliqk]

Thanks a lot , Good work ! What if i need to do this for google cardboard , is there a way if i can set autotimer for the bullets as i wont have any button in VR ?

[@MatthewHallberg]

So, I am not exactly sure how to do this for cardboard and make it look good. You could try two textures 1 for each eye and just play with the orientation until it looks good, or maybe try added the google vr package to the scene and basically do the setup twice, once for each camera. You wouldn't need the gyro code in that case because google vr will take care of that part. Also, you wouldn't want an autotimer but rather cast a ray from the center of the screen and if the raycast hits a ship thats when you would shoot.

[@shaliqk]

MatthewHallberg Ill look into it , Thanks for the reply :)

[@MatthewHallberg]

In the video I explain how to handle if the rotation of the webcam is different. You might have to invert the x scale or rotate it around so its upside down in the editor but right side up on the on the phone. Either way I am doing a new markerless tutorial that will be much easier to follow, and should work on any device. Should be out in a few days.

[@maherrhouma3478]

Hi Matt, Thanks for the tutorial. I am encountering one issue tho.When I rotate my device/camera, the spacecraft or even a static object looks like orbiting itself. It looks like theres a relation with the camera probly? Or the gyro function are behaving weird? Thanks again for the tutorials.

[@MatthewHallberg]

No problem, but yeah it doesn't work great. I went over doing this in type of markerless AR in Vuforia in my latest video so you could try to replicate this using those techniques. Might work a little better depending on the phone you are using.

works fine but camera seems to be rotated a bit towards left initially and enemy planes seems to be kind of unstable (movement working find but with camera background it moves a bit here and there) any solution for that? even while rotating mobile, video projection seems a bit laggy

[@matebarkoczi8690]

Hey! First of all thank you for the video, because it's easy to follow and well understandable! On the other hand I can't use my webcam (first step). Somehow I'm able to set it on, I don't see the anything in my monitor. I do the same like you, I copied the script from your website, I set the same position for the Main Camera and for the Plane. Unity says an error: NullReferenceException: Object reference set to an instance of an object. I don't really no, what does it mean. And suddenly you get a Plane after 3.29 minutes in the video and I don't really understand how and why? The AR Camera Assets work fine on my computer so I have the necessary drivers and stuff between Unity and the Webcam. (I have a Mac with OSX High Sierra and Unity 2017.3.0f3.) I hope, you can help me. Thanks in advance.

Thanks a lot. I can get this done on android galaxy phone. Just another question about AR, any idea to implement something like real world collision with the spaceship? And if I would like to track the real room size in order to generate corresponding size of spaceships, any tip to achieve this? Or it should be done on openCV? I didn't have much experience on tracking with phone. Will be appreciated if you can give me some advice.

[@MatthewHallberg]

Yeah I don't have much experience with it either, it could probably be done in some fashion with OpenCV but for better results you would probably need some kind of depth sensor like a project tango device.
