very well produced, thanks

 

Great one...thank you very much

 

Oh, and I'll just add:

It is recommended that you have learned the fundamentals of object-oriented programming before reading these lessons.

 

looking forward to 9, 10, 11 ..... how many will you produce ?

Thank you

 

As many as it needs to finish teaching the game. I may even go to multiplayer networking after the game is finished.

 

Great !

Thanks for making these!

 

Nice work, that should help a lot of people.

 

Hi

There seems to be some missing illustrations from the 9th pdf file

thanks

 

very good tutorials thanks for your work

 

Yeah its a bug in LibreOffice that corrupts embedded images when autosave kicks in. The OpenOffice devs are too busy pointing fingers instead of fixing it.

I've fixed the document, let me know if there are any other problems.

 

Hi

Where might I find the fixed pdf ?

Incidentally, I was reading you blog site and I noted your comments on MonoDevelop. I too share your thoughts about it. NotePad++ is also my preference.

Thank you.

By the way, there are some errata on Lesson 8, wherein I changed the code upon enemy death, and added code on how to lock the mouse cursor. Lesson 8 is available in the same URL as always: http://dl.dropbox.com/u/25260770/UnityLessons/FeuUnity3dLesson8.pdf

 

thanks !

 

You did a great job! you should make it all in a single pdf file. It would make a very good book.

That's about all of it for now.

 

just awesome!

Thank you for this!

 

wow this looks good.

bookmarked.

 

wowwwww, thanks very much, very awesome

 

I've been going through them and they are really good, simple and to the point.

 

If you have done networking before you should most definitely do that too. Your descriptions are clear and I prefer your tutorial to the Unity prodived ones.

cheers!

 

Seems like a very nice and thorough tutorial, but it honestly didn't get off to a good start for me.

I downloaded the zip with the assets and notice there are 2 folders with the same assets. Instant confusion.

Then I open the first pdf and it tells me to open the lesson 1 project. Looks through the assets folders, nothing. Looks through your dropbox folder and this forum and still nothing. Confusion growing. Is there a folder missing from the zip file?

 

Thanks.

 

Nice stuff. Thanks for taking the time to create it.

 

It seems it was just the first lesson that was a little confusing with the missing project folder. The rest of the tutorial is excellent.

Even though it's a simple tutorial I'm learning quite a bit because you're explaining everything so well. Like what the "out" keyword or "SerializeField" actually does.

 

Absolutely excellent tutorial.

Thought me a lot about GUI, animation etc. Things I've been avoiding before because they looked boring.

The only thing that bothered me is that you didn't explain the virtual and protected keywords when you used them in the end. Still not sure what they do.

This could easily be a book. Great work.

 

Uber cool. Really great. Wow. Talk about community spirit!

Thank you.

 

Oh man, sorry, I completely forgot about that. While I'm busy right now, when I get the time, I'll fix that.

 

Ok, I tried my best in explaining virtual and protected in Lesson 17. I added the Lesson 1 project in the Lesson Assets zip file as well.

 

Really helpful man.
Thanks!

 

Seriously great stuff. As a new to Unity user as of two weeks ago, thank you for the hours you put into this.

 

Very nice tutorials! I see lots of thought was put into this.

 

To my favourites!
Thanks a lot!

 

nvm found it

 

These tutorials are great!
except in lesson 9 I didn't have the 'Player-01 Default' material, but it gave me something called 'main_player_diffuse_deleteme'
any suggestions?

 

Probably Unity 4 does things differently now. It shouldn't matter what the exact name is, it should still essentially be the same thing I'm referring to in the tutorial. Send me a PM (so I can get notified) if things don't go working properly.

 

How could I miss these tutorials! They look so great. It is obvious that you've spent lots of time to make them. Thanks a lot. I'll also share their links on my blog.

P.S: I advise you to change the title of this topic if you can, something like "Free e-book" maybe

 

I love this.
Ive just picked up Unity, so am using this as one of my first walk throughs, then I may use it as a teacher too.
However Im having problems downloading the assets zip file.

Is it ok still as i get a 404

 

You can either use it or that one.

 

Amazing tutorials, getting through the 6º one at the moment! Love the way you explain things, that you have packed the resources... Definitely, a must for begginers like me, seriously. Thanks for putting so much work in this, and giving it away for free.

edit: Quick question if anyone can help me with it... I´m going through lesson 8, but the raycasting seems to malfunction, returning null reference exceptions. The code is exactly like the one you provided, but it still doesnt work...

 

Can you give the code here if it is short?

 

It is. This is the Health script:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Health : MonoBehaviour {
5.  
6.     [SerializeField]
7.     int _maximumHealth = 100;
8.     int _damageDealt;
9.     int _currentHealth = 0;
10.    
11.    
12.     void Start()
13.     {
14.     _currentHealth = _maximumHealth;
15.     }
16.     public void Damage(int damageValue)
17.     {
18.        
19.          _currentHealth -= damageValue;
20.        
21.        
22.     }
23. }
24.  

And the RifleWeapon script;

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class RifleWeapon : MonoBehaviour {
5.  
6.     [SerializeField]
7.     int _damageDealt = 50;
8.    
9.    
10.     void Update () {
11.         if (Input.GetButtonDown("Fire1"))
12.         {
13.             Ray mouseRay = Camera.main.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0));
14.             RaycastHit hitInfo;
15.    
16.             if (Physics.Raycast(mouseRay, out hitInfo))
17.             {
18.                 Health enemyHealth = hitInfo.transform.GetComponent<Health>();
19.                 if (enemyHealth != null)
20.                 {
21.                    
22.                     enemyHealth.Damage(_damageDealt);
23.                 }
24.                
25.             }
26.         }  
27.     }
28. }
29.  

I´ve tried tweaking here and there, but I can´t put my finger on the problem that pops out the null reference exception... Thanks for the help, anyway
