Unity 3 Video Training Course (FREE) - Walker Boys

When it happens I have to clear the browser's cache and try again. But when it works once, it doesn't happen again (not that I have seen at least) unless I clear the browser's cache (or use a different browser).

 

Hi!

Why can't I find the tutorials from "Unity app 1 19" to "Unity app 1 29"?
They ain't on your Vimeo Channel. Are these been deleted or just missing?

Thanks in advance!

 

Hi Kirath. If I remember correctly, the files for that portion of the video are up to the user to create or gather the textures and images. Hope that helps. Let me know if you have further questions. Thank you.

 

Hi again,

Having problems again with the videos. The videos named "Unity app 02 ##" cant be loaded for some reason?
Have I missed something or what?

Thanks in advance!

 

Thank you for the videos, I've been watching them all non-stop so far, and it's really easy for me to follow and goes really in depth on the topics. I saw a video on a website about how anyone can make video games and it's always been a wish of mine to be able to do so. Even with no experience except taking a year of java programming in high school I've been able to keep up with the video, and even my knowledge of java is being refreshed with your videos.

I have a few questions though. I'm wondering if the videos will later tell me how to:
1) Make AI
2) Make animations for the player (I've been interested in making an FPS and a 3rd Person shooter like the AngryBots demo)

I don't want to skip ahead through any of the videos because I know it will not benefit me to do so. However, my curiosity is aroused by those questions as I am aware I will need those in my games. Regardless of the answer, I plan to watch the rest of your series.

Again, thank you for the videos. I'm learning a lot and having fun at the same time with Unity.

 

You can't skip... atleast not to the way later ones depending on where you are.

As for AI, I guess the goomba vids is sort of AI ish... yea... So yes you will, though as it's a 2D Mario series, there isn't much AI in it. I would guess the 3D Mario will have better ones. As for animation, none as of yet, unless you count how to read through a spritesheet. I can't see that being part of this series, the animation will probably be included.

 

Anyone has any idea on moving platforms? Slippage and fall through is absolutely destroying me.

 

Hi pothb. Not sure exactly which part you are talking about for moving platforms, but if it's about keeping Mario on the platforms, then you'll want to look at the following example from the api -> http://unity3d.com/support/documentation/ScriptReference/Transform-parent.html

Remember, if you parent him to the platform, there's no slipping off or odd movement.

 

Actually that would be it. The optional part of creating a new world for part 4. I've been experimenting with friction, force, and looking for help in questions...

I'll try that... funny how i never thought about it as I parented box colliders to create limits for the movement. Thanks.

 

A lot of thanks for WalkerBoys Studio!!!! you are great!!!!

 

please try to check my post in http://forum.unity3d.com/threads/69938-Unity-3-Video-Training-Course-(FREE)-Walker-Boys/page21

it may give you some idea how the parent work with gameObject between child gameObject

 

I'm on the Part 55 video on gumba pathnoding in the 2D Mario Clone lab and I'm getting an error that I don't see on the video. I'm sure it's just something I'm missing, but I can't seem to figure out why. The error in Unity says: Cannot convert 'PathInstruction' to 'GumbaState'. The code I have is

Code (csharp):

1.  
2. if(other.tag == "pathNode")
3.     {
4.         var linkToPathNode = other.GetComponent(pathNode);
5.         gumbaState = linkToPathNode.pathInstruction;
6.     }
7.  

and my variable declarations in each script are as follows

Code (csharp):

1.  
2. enum PathInstruction {moveLeft = 0, moveRight = 1, moveStop = 2, jumpAir = 3}
3. var pathInstruction = PathInstruction.moveStop;
4.  

and

Code (csharp):

1.  
2. enum GumbaState     {moveLeft = 0, moveRight = 1, moveStop = 2, jumpAir = 3, enemyDie = 4, goHome = 5}
3. var gumbaState  = GumbaState.moveLeft;
4.  

 

yes, if your use Enum in Javascript, it will have error

because they are different "class" enum

try to change to use = 1, =2, =3
or u need to type cast it
or make it as a public enum

my project example:

Code (csharp):

1.  
2. if ( other.tag == "pathNode" )
3. {
4.     var linkToPathNode = other.GetComponent(pathNode);
5.     gumbaState = linkToPathNode.pathInstruction;
6.        
7.     if ( linkToPathNode.overrideJump)
8.     {
9.         jumpSpeed = linkToPathNode.jumpOverride;
10.     }
11. }
12.  

 

I'm sorry I must be missing something. Is there an error in the code shown in the videos then because I double checked that my code matches theirs exactly up until this point and my code seems to look the same as yours except for the stuff I haven't gotten to yet. Thanks for the help.

 

make sure 2 of your Enum is same ordering ( I same like haven't follow boys use =1, =2, =3, =4)

Code (csharp):

1.  
2. // Gumba AI
3.  
4. var moveSpeed : float = 20.0;
5. var attackSpeedMovement : float = 35.0;
6. var jumpSpeed : float = 3.0;
7.  
8. enum GumbaState { moveLeft, moveRight, idle, jumpAir, dead, respawn };
9.  
10. var gumbaState = GumbaState.idle;
11. var attackRange = 1.0;
12. var seacrhRange = 3.0;
13. var returnHomeRange = 4.0;
14.  

Code (csharp):

1.  
2. // Path Node Helper
3. // Description: Help control the logic of the enemy as it moves in the world
4.  
5. enum PathInstruction { moveLeft, moveRight, idle, jumpAir, dead, respawn, removeTrigger };
6. var pathInstruction = PathInstruction.idle;
7.  

 

I changed my declarations to get rid of the = num as follows and even changed the gumba state to moveStop but still no change Here's my new code

Code (csharp):

1.  
2. enum GumbaState {moveLeft, moveRight, moveStop, jumpAir, enemyDie, goHome}
3. var gumbaState = GumbaState.moveStop;  
4.  

and

Code (csharp):

1.  
2. enum PathInstruction {moveLeft, moveRight, moveStop, jumpAir}
3. var pathInstruction = PathInstruction.moveStop;
4.  

 

What actually error line number in Unity?

Can you try to post yr full code? hard to debug this way ...

 

I remember that I have same problem with you before XXD

 

It was this line:

Code (csharp):

1.  
2. gumbaState = linkToPathNode.pathInstruction;
3.  

Here's the entire function I have

Code (csharp):

1.  
2. function OnTriggerEnter(other : Collider)
3. {
4.     if(other.tag == "pathNode")
5.     {
6.         var linkToPathNode = other.GetComponent(pathNode);
7.         gumbaState = linkToPathNode.pathInstruction;
8.     }
9. }
10.  

My exact error is BCE0022: Cannot convert 'PathInstruction' to 'GumbaState'

 

hmm ... try type cast it like, and see it will work or not in yr case:

Code (csharp):

1.  
2. function OnTriggerEnter(other : Collider)
3. {
4.     if(other.tag == "pathNode")
5.     {
6.         var linkToPathNode = other.GetComponent(pathNode);
7.         gumbaState = parseInt(linkToPathNode.pathInstruction);
8.     }
9. }
10.  

 

That worked perfectly thanks

 

Nah, I got it. It took me a few tries as the Heirarchy didn't update properly, but after a while I noticed what I had to do. Thanks anyway though.

 

Try to use a GameObject as a Container of others object,

u can have a lot of Empty Game Object to holding it own Position and Rotation
to help you stored the information

 

Just noticed something, in my own game and the others that posted up theri websites. In the Mario 2D, when enemies walk to you, they completely ignore your hit collision triggers, until you move. How would you "combat" this?

Would you just put the code in a different function, and have both objects have ontriggerenter for the same event and call that function?

 

@pothb: If I remember correctly I solved the problem by adding Rigidbody's to all collision boxes (left and right) of the Gumba. Furthermore, all collision boxes of my Mario (body, feet, head) also have Rigidbody's. Mario's body collision box should now register any Gumba collisions via OnTriggerEnter() for both moving and non-moving situations correctly.

By the way, you can take a look at my finished Mario clone here: http://unitygames.netii.net/

 

Nice game, Red baron. Much more effort than me. I got tired near the end and keep putting it off. Thanks for the advice. I'll try that when I get home.

 

Man I have been waiting 3 days for mt first lab to be graded. Ugh I know it takes time but ahh the stress!!

 

Yep, that worked perfectly Red Baron. Thanks.

Sakocs, make sure you sent to the right email and check your junk mail.

 

Hi I'm from Venezuela I am grateful to you
great idea I'm following the course but not speak or understand English but not to limit me boy so thanks

: D: D

 

Not sure if anyone has had this problem , but i'm having a problem in lab 1 . If I add the code for storeClicks and run the game the explosions keep cloneing and if I take the code out the problem goes away.
not sure if it's because i'm using unity 3.4.
I've followed exactly and have tryed a number of time with the same effect.

 

Did you click play oneshot?

EDIT: This is a shot in the dark since it's been a while since I've looked at lab 1.

 

@pothb thank you. I did email cwalker<@>walkerboystudio.com but i will try again from the email i have been using for the rest of the course. unfortunately i now need to wait for the free host site to come back up.

I have re submitted and it can be found at http://www.madness-media.com/menu1_3.html while the free host site is down(dont know how long message said it was a ddos attack).

 

The enemy explosion is run in the Update function, so it's firing all the time if you made a wrong comparison or forget to make an if-loop. Perhaps you switched place with storeClicks and numberofclicks in the Start-function? storeClicks has to go first, else you'll put in 0 to that variable all the time. Make sure that after the explosion, it goes right to the respawn function.
Try go through it again, it should be easy once you sit back and take a fresh look at it.

 

hi guys,

I haven't submitted this Lab2 to WB yet, but it's almost done.
Feel free to try it out, feedback appreciated as it's still in alpha.
I'm wrapping it up this following week, so it won't change that much. Still working on online highscores, GUI, the musicscore and minor script optimizing.
Thanks to all who submitted Lab2 before this, you've been my inspiration to do it this way.

cheers

 

Looks Great keep up the good work.

 

Wow, really amazing job!!
But I've noticed that the word "mars" appears near the planet =P But you probably know that since it's still in alpha.

 

I have to agree with Thiago6891, that looks amazing!

 

I have come across lots of unity 3d tutorials video, from burgzergarcade to tornodo twins, unitystudents etc. etc. and all of them were great , but I have to admit that this has been by far, the most "structured tutorial videos" I have come across so far.It's a sad thing i figured this set of videos a week ago. Any way Thank you Walker Boys studios!! for putting this amazing set of video tutorials, and free of cost. The time, energy and the patience you guys have put together deserves to be praised. God Bless you Guys and every one at the forum!!

 

Hi Guys,

I am Bhanu and I newly joined this forum. I downloaded a car tutorial from Unity website and followed the instructions exactly as it was explained in the tutorial but I get the following errors :

I am using Unity 3.3 on Windows 7 and the script file is attached to this message.

Please someone help me. Thank You

Bhanu

 

I never read this tutorial so I can't help you. But try posting this in its own thread and you should get help.

 

Same here... there are people who look into this thread that might know, but you are lowering your chances by using a thread completely unrelated.

 

Thanks guys, yes the "Mars"-word is because I haven't done any details brushup yet.

Hope you like the starfield and did you get the magma and try it?

 

The starfield is pretty awesome! But I didn't get any magma... I figured it was in alpha and there was no magma, gonna try again later!

 

ProfCWalker, I have a question. I've completed Lab 4... though I did lack the score part. But in any case, it came out as too big to upload to the site. Is there any other way to get it to you? I have hostoi, and they only allow 5mb max upload. I've tried to send you a link to a rar download, via megaupload. Is that sufficient?

 

Hi Kale,

Yes, that would work, however you could also use Dropbox for free and have sufficient space for future projects as well.

Let me know if you have further questions. Thank you.

 

The game is points based, rather than powerups just pop up randomly. So you have to get a certain amount of points before any powerups appear, the shield being the easiest to get. You'll need 400p to get magma, and with that, the biggy stroids should be no problem. The tricky part is getting 400p before the big stroid wave

 

Oh, if only I stopped dodging them and started shooting!! lol

 

I got it now, 657 points \o/
The magma is pretty cool but quite difficult to get, and autofire would help me avoid carpal tunnel syndrome

 

Does anyone know how I can get videos 19-29. It jumps straight to 30?

Thanks,


j-

 

Yes, I've been wondering if I should make autofire a powerup or just put it in. I'll do something for sure
