I am trying to make a VR game with google cardboard in unity. However we can not find a way to display score text right in front of the player. However when I add 2D text it is only on one side and therefore on one side of the eye and getting the position right for 2 texts is hard. If I use 3D text and set in front of the players position I think it will go into the wall if a player hits one. Is their any way to display a score on google cardboard / Unity VR.
You can either use native Unity Canvas UI or Googles hack to render OnGUI calls onto a texture.
I would definately recommend Canvas as that is the way Unity is working on their UI features, and it has much better layout capability.
To use canvas, Right click in the hierarchy and add UI->Text. You will automatically get a canvas. The important part is set the canvas to world-space (not screen space overlay). Then drag the canvas game object so it is a child of the Google Cardboard Main head object. Scale it down (like x:0.001,y:0.001,z=0.001) because by default it will be massive. To avoid going through walls position it about 0.5m in front of the camera - within any collider you may have.
there is another approach as well which you can place that canvas under camera make it world space, and then adjust it as you want, after that where ever you look at it will be seen easily ( as suggested by earlier user in answers) as you can see below in picture i placed canvas > Text > under camera which i used for oculus/ google camera

I have a first person controller and currently if I walk into a slightly transparent object, it disappears until I walk out of it.
I have a 'water' cube object that is very light blue and transparent, and when I move my camera into third person view then enter the water, my screen turns light blue which is good. In first person mode (which is what I'm trying to figure out), the cube disappears and my screen color remains the same.
I know it has something to do with my camera but even after going through all the features on unity docs and changing a few settings in the inspector, it all remains the same.
Like mentioned in the comments your cube is not visible because the backside of its faces is being culled, meaning they are not rendered. This is not a camera setting but a property of the shader your water cubes material is using.
You could create get a duplicate of the shader your are using where you add Cull Off to change this.
Read about it here.
If you want to go that route you need the source files for your shader. Assuming it is one of the Unity Built in shaders you can get them from the Unity Download archive here for your Unity version.
Clipping the camera trough objects is rarely a desired and you should look at a different way of achieving your effect like using a post-processing volume because the "water" would still be a cube and be drawn behind everything in front of its faces.
For example in a FPS type game this would result in the gun not changing color.
I am trying to create a Brawl Stars clone for fun purposes. I created all other mechanics but there's one which i can't seem to figure out.
I am trying to create an Aim Bar which will let player know which direction he is currently aiming at...
Also i want this effect to only be visible when player is either moving the aim joystick or holding the aim joystick.
How can we create a Line Renderer in unity which rotates depending upon the joystic's current rotation. I want to achieve a similar effect to how Brawl Stars does with its aim bar
I am using Free Joystick Pack from unity asset store
Link to Joystick pack -> https://assetstore.unity.com/packages/tools/input-management/joystick-pack-107631
Here is an image of how i want the effect to be...
I'm using Unity 2020.1.17f.
To do align correction between VR lens and Display, I want to control size of screen, offset of screen, and rotation of screen(screen means area of display where actual game scene is appeared, my game has letter box in 4 ways).
I could control size and offset by changing values of Viewport Rect, but I cannot find a way to control rotation of screen. (Like Cv2.GetRotationMatrix2D() of openCV in C#)
You can say "why don't you rotate your camera?", but rotating camera is not what I want. As you know, in VR, Game screen is distorted in several shapes to optimize to their lens shape. Thus, even I rotate camera, it is not helpful for mis-align correction.
In Google, there are many answers, but only related with rotation of mobile phone, not controlling rotation in arbitrary angle(that what i really want).
How can control of rotation of game screen?
You need to go to Edit/PlayerSettings/Player
And open the section called resolution and presentation
as you see there is a section called default orientation and here you can set the orientation of the build just opened.
Down there is also a section called Allowed orientations for auto rotations where you can set the other rotations allowed. In my case, everything is allowed, but you can just set the 2 landscapes or the 2 portraits depending on your game and your canvas and camera orientation
Does any know or can possibly point me to some instructions or a github repository on how I can create a script where I have an object and in GoogleVr (Cardboard) if I was to gaze over an object, a tooltip would appear?
If anyone is familiar, in the Cardboard Demos under Under Arctic Journey > Learn, when you click on the fox, a tooltip appears to showcase that item along with like a brief description on it. I want to have something similar (maybe even the same thing) except just having a gaze over will automatically show it. Is this possible?
I want to have this done on multiple objects in my project so I want it created so I can easily substitute out text and whatnot.
Have a script with a reference to a World Space Canvas (WSC). The WSC will be your tooltip and be activated when you hover over the object and disabled when you don't.
You can set images and texts of the WSC through the inspector or through code if you make a reference to them.
The script should also always have its rotation set to face the player.
You can use the SetActive(bool) method to show or hide the WSC.
The UI system makes it easy to create UI that is positioned in the world among other 2D or 3D objects in the Scene.
Start by creating a UI element (such as an Image) if you don’t already have one in your scene by using GameObject > UI > Image. This will also create a Canvas for you.
Set the Canvas to World Space
Select your Canvas and change the Render Mode to World Space.
Now your Canvas is already positioned in the World and can be seen by all cameras if they are pointed at it, but it is probably huge compared to other objects in your Scene. We’ll get back to that.

How do I make so when I move the camera(with touch) it doesn't go beyond the scene borders?
How do I move the camera with touch so it moves strictly with scene parts, like slides(swipe-first slide, another swipe-another slide) with not going beyond the borders of the scene?
The game I'm making has a camera like in Disco Zoo game for android (I'm a newbie)
Technically, the scene doesn't really have a border. You'll need to define the border somehow within your game, then constrain the camera's position with something like Mathf.Clamp(value, min, max) in an Update() function on the camera.
How can you define the border? It's up to you. Some ideas:
Hard-code the values in the script that clamps the camera. Probably the quickest option, but not flexible
Make public parameters on the camera script that let you set min and max positions in the X and Y directions
If you have a background image: use the extents of that to define your camera's extents
Create empty objects in your scene that define the minimum and maximum extents of the scene. Put your "min" object at the top-left, and the "max" object at the top-right. Connect it to the camera script, then use those positions to see if you've gone too far in any given direction. The main reason to do this is that it's visual.
(Slower, but dynamic) If everything in your scene uses physics, you could search the entire scene for every Collider component, then find the furthest extents in each direction. However, this is probably going to be pretty slow (so you'll only want to do it once), it'll take a while to code, and you'll probably want to tweak the boundaries by hand anyway.
