My game has this system where the player is rewarded with hearts.
Whenever a heart appears, it's supposed to appear with a value on it (say, +5). I did some googling and everything said I need to attach a canvas to the sprite and then a text component to the canvas. However, this doesn't seem to do anything.
You just need the following structure
Sample Image settings: (Here you'll want to replace the "Source Image" with your heart sprite)
Sample Text settings: (Although I recommend using the TextMeshPro component instead)

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 Line Renderer that renders a line between several objects augmented with Vuforia image targets.
I understand that the Line Renderer component has the "Alignment" field which can be set to either "View" or "Transform Z". For my project, I need the rendered lines to always face the camera, so I have that field set to View. Here is a picture of the component:
However, in both the Unity Editor preview and on my deployed Android application, the line rotates along with the objects (for example, if I move or rotate the image target). The ARCamera is already tagged as MainCamera, so it should be recognized as the camera.
Once I noticed this, to test if the field was being overwritten somehow, I added the line lr.alignment = LineAlignment.View; to both a start function at the beginning of the application, and to an update function, to make sure it is always set to View, but that did not change anything.
Is it possible for the Line Renderer to always face an ARCamera? Is there a step I am missing?
Here is a picture of the issue, where you can see that two of the lines are rotated to their side (the top line between the blue and green spheres is hardly visible).
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.

I am trying to display the score for my game, however, my background sprite is drawing right over it. I have tried assigning some type of layer tag but I can't find one for text. Everything I try, the text is always hidden under the sprite for my background (and any other sprite for that matter). Is there a way to assign the text to be drawn over everything, I have tried looking at tons of sites in hopes of a fix but I can't seem to find anything. Any help is extremely appreciated.
From the hierarchy creation menu, pick UI->Text
This will add you 3 Elements to the hierarchy: Canvas, and 2 child gameobjects which are Text and EventManager. These are all needed for the proccess.
The text gameobject is part of the UI system Unity has, means that if done correctly, it should show over all sprites.
Programmatically you can change text by simply saying:
myUItext.text = "Text that will show on UI!"
Manually you can change position, font and text using the hierarchy view.

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
