You are asking too many questions at once. Most of them are very basic too. I suggest you try to follow along these tutorials:

http://walkerboystudio.com/html/unity_training___free__.html

They are free and should cover most of your questions, one way or another. They have helped me a great deal in the past.

I'll try to answer some questions here. To get some more info you could also try opening the Unity scripting reference from inside Unity. If you do it this way, you don't need internet.

- You can use: yield WaitForSeconds(3); this will wait 3 seconds before running the lines after it.

- If you want to use a button to make something happen use OnGUI to place a button. Then use the update function to always make the camera go to a certain location, that you set in the GUI button.

- you can hide things by turning off their renderer. Something like:

Transform.render.setActive = false.

- I save a really good video about touch input on mobile a while ago. I'll try to find it again and get back with some of the examples they show in there.

- The most simple way to save things in Unity is Playerprefs.

If you explain a bit more what you want to achieve exactly I might be adable to show some examples of how you could code it.

Hey thank you man really a lot. About saving, i just want to save some strings and integers. Like what answer is already done and what was the answer.
About touch input can you give me simple excample like: object is clicked, print message object is touched. With no possibiliti of more than one touch, i want this enter options os start or statistics. Also can u give me excample for scrolling page down, like not every lvl can get on one scren so u have to scroll down to see the rest

You can save strings, ints and floats using PlayerPrefs. PlayerPrefs.SetInt("intIDName", 1) .GetInt("intIDName"), SetString, GetString, GetFloat,SetFloat.

Just browse the unity documentation on their website. All the information about touch events et cetera are in there. Just like PlayerPrefs, SetActive(), as is everything else you're asking for.

Simple Google searches would've given you all these answers.

you can give objects different tags. You can then check by it's tag like so:

if (gameObject.tag == "sometag")
{
     //do stuff
}

For the touch input you can do something like this:

function Update()
{
     var ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).phase == TouchPhase.Began);
     var hit : RaycastHit;
     if(Physics.Raycast(ray,hit))
   {
          if(hit.collider.tag == "Cube"
          {
               Debug.Log("You've hit an object tagged cube");
          }
   }
}

This will cast a ray from the camera to the place that you've touched the screen. It will then look to see if what you've hit has a certain tag. If it does it logs a message in the console.

I've haven't tested it, so I'm not sure it works exactly like that but it should point you in the right direction.

Okay, I have never used raycast before, so it registers click over colision? because I use collision on models? I know I maybe sound like retard right now, but I guess I am for this.

EDIT, also does it hits only first object, or and objects behind it. because I will have some objects behind.
thx for answering
