How do I properly "attach" an image on a GameObject?
Without knowing what you want the image for, there are different ways to have an object render as an image.
Assuming you're trying to make a 2D game, it sounds like what you are looking for is the Sprite Renderer.
The GUI texture you tried to use is deprecated and was part of an old system for menus and UI elements. If a UI is what you're after, take look at UI Image.

I am learning how to make games using unity, i have used free sprite packs from unity's store.
i have selected each individual sprite and changed its z position to 0, but when the game runs it looks completely different to how it looks in the editing window.
please help.
Here is a video I recorded.

Are your sprites on a prefab, or children of another game object? The Transform of the parent object affects the transform of all children.
It looks like this is a camera problem. Your camera is set to perspective, it is possible to do parallax backgrounds with a perspective camera and you may have already accomodated for it, but that is the first thing I would check.
You can modify this by going to your Main Camera and selecting Orthographic from the Projection drop-down menu.
I want to implement as showed in the below image in 2D game, I can find so many tutorials for 3D like mini map concept but for 2D i couldn't find anything. In my game i want to show a secondary
camera as in below image and also i need to zoom the content that will show through it. I developed one concept but it can be done with sprites or with Canvas in World Space mode. So you can see
they won't resize or positioned according to the screen resolution. If you guys have any idea how to do this task,it will be very helpful for me. And i also tried with depth mask shader .Thanks in advance.
Use a camera with target texture
Follow my tutorial here: Particles with Dynamic Text but disregard the parts about the particle system, they are irrelevant for you.
Once you've made a material, stop following the tutorial, and instead:
Create a sprite renderer on a canvas that is "Screen Space - Overlay" and set the material to be the one that you created.
I am trying to implement a game over screen for my Unity 3D based game for Google Cardboard. I have tried using the image UI component on a canvas component. The image appears just fine but the issue is that it seems to show up over the reticles. I would like to have the image perfectly fit the inside of the reticle. I am considering somehow finding out (somehow) the size of the reticle and exporting my image as a png with transparency around its graphics.
My Question:
Is there a better way to do this? If not, what are the dimensions i can use for the duplicate images (for the two reticles) to perfectly fit the Google Cardboard reticle openings.
When using Google Cardboard (Now GVR), I think it is best to use Quad GameObject for Game Over screens to which you can add images and child objects like 3D Text and collection of child quads.
The best thing about using quads and 3d text is the extent of scripting that can be done to make them dynamic as well as styling. And in your case, Physics Raycasters work well for the reticle to interact with those GameObjects.
You can add materials and textures to the quad and what not! I personally love quads for GameOver screens as well as a lot of other interact-able things.
I am using Vuforia 4-2-3, the latest NGUI verion and Unity5.0.1.p3
My GUI works fine until I track a target. After that, my GUI is invisible However, the collision still works. So buttons are working, only I can't see sprites, textures or labels.
There is a 3D building that shows up while tracking. That 3D object uses the standard shader. The NGUI atlas uses the unlit/transparend colored shader.
I guess there is a conflict between those? Did someone else had this problem before?
EDIT:
This is what my hierarchy looks like
I have an Image Target with several 3D objects.
The NGUI and the ARCamera are two different objects aswell.
This is what my NGUI looks like, when I start tracking
Where have you linked your NGUI to? The ARCamera or another GameObject?
I would suggest you link your script to the ARCamera at all times. This would ensure that it shows, since a GameObject below the ARCamera it might not show since the hierarchy pattern to be followed by general Unity users.
EDIT: If you've used OnGUI() for your GUI needs, then the script in which its contained should be attached as a script on the ARCamera. Also, try putting ARCamera on top of Image Target in the Heirarchy.
I'm trying to build some simple game(learning) where you will have to clean objects.
That means for example you have a monitor with dust on it so you can't see the image. You then uses mouse or finger to move arround monitor to make image visible.
So what I've got so far is 2 images first being the monitor image and second being the dust before it. I've managed to realize when user swipped all image down. But what would I like to do is when user tap the screen somewhere only in that radius r the front image disappears.
I'm guessing I should be using layer mask, but I have no idea how to do it.
I basicly managed to write my own shader that only shows layer with correct image but no idea how to do that you can accualy get some cool effect from it.
Any ideas will be apriciated!
I would use render texture for this. It allows you to use image files as a brush. And it's quite fast. The idea is to use render texture as a mask. You start with black texture. Whenever player touches the screen you render your brush image to this texture. But this feature (render textures) is available only in Unity Pro.
You can still use texture as a mask if you don't want to buy Unity Pro. But this will be definitely slower than render textures. How much slower I don't know. The options are:
Create ordinary texture (Texture2D) and use SetPixel or SetPixels to update mask when player touches the screen. If you want to go this way, I would recommend to use much smaller texture than the screen size (4x, 8x depends on the quality you want to get). Otherwise it will be damn slow.
Create ordinary texture (Texture2D) and use ReadPixels. This works pretty much the same way as render textures but it's slower. This technique is explained here.
Using render texture (requires Unity Pro)
Ok. I've made an example: https://drive.google.com/folderview?id=0B60e_iFEZd1-RlB4LVN6NE84clU&usp=sharing
There are:
Image that player needs to clear from dust: Image.jpg
Image of dust that we draw on top of it: Dust.png
Image that we use as an erasing brush: Brush.png
Our render texture that we use as mask for dust: Mask.renderTexture
Shader that we use to update the mask: MaskConstruction.shader
Shader that we use to render dust (it combines Dust.png and render texture): Masked.shader
Script that brings everything to life: MaskCamera.cs
Main scene: Main.unity
I think this might be helpful. The Main objective of this Code sample is to create a dust/fog removing effect using Unity. Using, Texture Masking shader, Mask Construction Shader, Render Texture, Camera Masking Script and masking camera, you can create your own effect. Read on to know how and download the source code.
