How to Virtual Reality App FPS Game for Beginners with Unity and GoogleVR

[@nell7860]

Amigo gracias por tus videos, eres un gran apoyo y ejemplo para desarrolladores. saludos desde Bogotá

[@TheWadester1124]

This may be a silly question I have a rift, if I enable vr mode in unity editor will this tutorial work for it. I think it should want to get into vr game creation now. *** Update: works with Oculus. Will now tweak this and add a score system, enemy death sounds, etc........... Doing a Cartoon Western Zombie Theme

[@hashashin4087]

Maybe you should do an update tutorial with different types of enemies, score system and sound etc

[@abdulpresswala2351]

When testing the zombie, he shows just laying on the ground when i hit play. Script says it cant find NavMeshAgent

[@MatthewHallberg]

+Abdul Presswala sounds like you missed the reference to the navmeshagent make sure there is one on your zombie prefab.

[@abdulpresswala2351]

The navmeshagent is there on my zombie. The script just says it cant find it.

[@fatjoetr7770]

add "using UnityEngine.AI"

@@fatjoetr7770 Thanks that helped me !!

[@mkiwan996]

Please help, the animation of the zombie is playing once and then stops, how to make it loop

[@andrejpetrushevski9880]

@Vibin MB Thank you so much man

[@ForeverHopelessXD]

Very insightful video about building a amateur-friendly Google VR game. Also appreciate greatly that you wrote comments on your code, to explain what each line did etc. Thanks very much for this tutorial! Hope to see more of your content in the future.

[@anmolkp2710]

I am having a problem with fixing the alignment of the debug.ray ( the green line). Could someone please help me with that ?!

[@OrDileE]

bro, when i want to shoot, apper that: ArgumentException:The object you want to instantiate is null

[@walkwithwally]

I really like that you explain the code. Can you go more in depth with the code one day? or recommend a good read. I'm new to c# with only a bit of javascript knowledge. I don't want to hurt my head though... you seem it make it easy. that's why I'm asking you.

[@MatthewHallberg]

Yeah for sure, I have one more tutorial that might be slightly complicated but the general concensus here is people need more help with basics in Unity, so not the next video, but the one after that will be all basics and I will probably stay on the basics trend for the next few after that as well.

[@utkarsh1995ful]

hello I am using Unity 5.5.0f3 version and as soon as I import VR sdk package i have been prompted with error message: Assets/GoogleVR/Scripts/Video/GvrVideoPlayerTexture.cs(595,7): error CS1622: Cannot return a value from iterators. Use the yield return statement to return a value, or yield break to end the iteration. any help on that please do reply.

[@MatthewHallberg]

Oddly enough I got an error like this the other day among others and it was because my script was not named correctly. Make sure it is the same as in the video and it's case sensitive.

[@pauldanielmagdangal5052]

bro? why not building a game combination of vr and ar?

[@MatthewHallberg]

Good call, I definitely will do something mixed reality soon.

[@fadedlife2013]

For some reason certain walls and the ceiling keep clipping out of view in scene and game mode. I've played around with clipping plane in the main camera options... Nothing seems to be fixing it. Any ideas why?

[@MatthewHallberg]

So I never had the problem with things necessarily going out of view, but the planes were flickering where they overlapped for me, I just had to reposition them a little. Hopefully that helps. Other than moving the clipping plane closer to zero I really don't know.

[@mounaattie2519]

[@J0hnux]

I'm gonna use the code auto-fire in to making a Triggerbot hack in CS:GO. Thanks man.

[@MatthewHallberg]

Yeah no problem!

[@kristong]

Hi Matthew, was following the tutorial, for the "auto shoot" method by using "Debug.DrawRay", it worked well in the unity simulator, I can keep shooting as long as I'm aiming at an enemy, but can fire only one shot, then no more auto shoot when I run the program on an actual device (sony xperia xz) with cardboard. Don't know why, Have u tried on an actual device and saw that issue?

[@nevenahmed320]

hello i'm traying to make the same game but in AR what should i choose for the walkable area so the zombie can chase the camera

[@Cevyancs]

hi i'm from indonesian. why when shooting, the zombies don't fall

[@yasVFX]

The green line does not appear , I checked but nothing , pleas help : in the script i have this at line 53 :RaycastHit hit; //draw the ray for debuging purposes (will only show up in scene view) Debug.DrawRay(spawnPoint.transform.position, spawnPoint.transform.forward, Color.green); It seems correct : I checked in the Hierarchy and have : - Main camera - gun spawnPoint -GvrViewerMain - zombie - Scene - zombie (1) - zombie (2) - bullet With this I have always the same message :Object reference not set to an instance of an object

bro any help about bluetooth controller, i'm facing issues in that.

[@danielh.3098]

Hello Matthew, i've seen how interesting the game is. But i got a question When the game is ready, and lets say that u not play it with autofire function but with tapping the phone screen to fire the gun, do you think we can do it by tapping our fingers at the screen?

[@getknowledge3758]

[@simonefonta5030]

Why are the walls invisible on the other side?

[@aliyarahmanajihati708]

hello, I'm trying to implement your tutorial to my project and because of different positions and the way I make my game (I use both guns and melee weapon), gun is put as a child of HandPosition GameObject, which is the child of the Main Camera, which is the child of Player. Player. So I can't just put Gun as a child to my MainCamera because in my game you need to retrieve it first, store it to the inventory, choose it from the inventory, then the gun will be equipped to my HandPosition. Here is the illustration: Player Main Camera GazePointerRing InventoryPosition HandPosition Gun So I put your PlayerScript in Player (I tried to put it in Main Camera but the Raycaster doesn't even appear). As a result, the raycaster came out of the MainCamera (since MainCamera is the Child(0) of Player?). I thought it won't make any differences and that I should still be able to shoot, but then I tried to start shooting (as shown in your tutorial, minute 27:00) but for some reason my bullet can't get shot (even though I also put my bullet prefab in Resources). Any advice, please? It'll be very much appreciated

[@OscarTorresWork]

Not sure if anyone pointed out but Unity is saying your texture hasn't been marked as a normal map , it's telling you to press the fix button nothing to major, thanks for the tutorial by the way always helpful.

[@matiascardenas2186]

What I need to change in the script if I wanna use a button for shooting instead?

The Google VR SDK updated in May. Now add GVREditorEmulator to your scenes for the VR aspect. Also the game window doesn't show the stereo view anymore but it will be there when you build your game on the target device.

[@samfrankie916]

Go to that line in the script and its probably searching for something that it can't find so make sure the name of the game object it's searching for matches exactly what its called in the hierarchy (it's also case sensitive).

Matthew, is it possible to integrate an Arduino 101 to send bluetooth information to apps created using Unity and Google VR?

[@MatthewHallberg]

Yeah, I used the "bluetooth for microcontrollers" plugin on the asset store to do some other projects with Arduino and Unity however, it only works for Android. There are some other plugins you could try if you want something cross platform but they are a little more money. I have also used C# sockets to send UDP packets from Android or IOS to Unity with a WIFI enabled Arduino board and that has worked really well it also doesn't cost any money for plugins.

[@sanjeevx007JamesBond]

Thanks Matthew! If I need anymore help or am unclear I'll come back XD

[@MatthewHallberg]

Anytime. Good luck with the project. Integrating Arduino and Unity is one of my favorite things to do, have fun!

[@sanjeevx007JamesBond]

Hey Matt, most of the plugins aren't free. Maybe I'm not searching right. I've just discovered Ardunity tho. Is that the plugin you're talking about? Is it easy to use for ble connection to my Arduino 101? Any tutorials available?

[@MatthewHallberg]

yeah all the plugins for bluetooth at least are going to cost money, but if you just use basic sockets to send UDP packets from a wifi enabled Arduino to Unity that is free.
