Space Shooter Tutorial Q&A

All the videos are here: https://unity3d.com/learn/tutorials/s/space-shooter-tutorial

 

Thanks; any idea why the links weren't working though? I'd hate to run into the same problem with other tutorials/practice projects.

 

No idea at all. All the tutorials are here anyway: https://unity3d.com/learn/tutorials

 

iv only just started the script and im getting errors thrown help please

 

Code (CSharp):

1. Rigibody rigibody;
2. void Start()
3. {
4. rigibody = Getcompoment<Rigibody>();
5. ........
6. }

It will work.

 

Me too! Thanks for the update!

 

I have one error for the restart function (Ending the game)
Error 1. Keyword void cant be used in this context
here's my code

void Start()
{
gameOver = false;
restart = false;
restartText.text = "";
gameOverText.text = "";
score = 0;
UpdateScore();
StartCoroutine (SpawnWaves());
}

IEnumerator SpawnWaves()
{
yield return new WaitForSeconds(startWait);

void Update()
{
if (restart)
{
if (Input.GetKeyDown(KeyCode.R))
{
Application.LoadLevel(Application.loadedLevel);
}
}
}




while (true)
{

for (int i = 0; i < hazardcount; i++)
{
Vector3 spawnPosition = new Vector3(Random.Range(-spawnValues.x, spawnValues.x), spawnValues.y, spawnValues.z);
Quaternion spawnRotation = Quaternion.identity;
Instantiate(Hazard, spawnPosition, spawnRotation);
yield return new WaitForSeconds(spawnWait);
}
if (gameOver)
{
restartText.text = ("Press 'R' for Restart");
restart = true
break;
}
yield return new WaitForSeconds(waveWait);

}
}

public void AddScore (int newScoreValue)
{
score += newScoreValue;
UpdateScore();
}

void UpdateScore()
{
scoreText.text = "score: " + score;
}

public void GameOver()
{
gameOverText.text = "Game Over";
gameOver = true;
}

}

 

Hi I am stuck on lesson shooting shots, following the tutorial updated my player-controller script, but when I hit play and click to fire the bolts seem to be stuck right in front of the player ship and doesn't travel forward. I can see more bolts piling on top of the existing shots and non moves forward. when I drag the prefab bolt into the scene it move forward as expected. Any idea on where I might have gone wrong ?

here is my player-controller script:

using UnityEngine;
using System.Collections;
[System.Serializable]
public class Boundary
{
public float xMin, xMax, zMin, zMax;
}
public class PlayerController : MonoBehaviour
{
public float speed;
public float tilt;
public Boundary boundary;
public GameObject shot;
public Transform shotSpawn;
public float fireRate;
private float nextFire;
void Update ()
{
if (Input.GetButton("Fire1") && Time.time > nextFire)
{
nextFire = Time.time + fireRate;
Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
}
}
void FixedUpdate ()
{
float moveHorizontal = Input.GetAxis ("Horizontal");
float moveVertical = Input.GetAxis ("Vertical");
Vector3 movement = new Vector3 (moveHorizontal, 0.0f, moveVertical);
GetComponent<Rigidbody>().velocity = movement * speed;
GetComponent<Rigidbody>().position = new Vector3
(
Mathf.Clamp (GetComponent<Rigidbody>().position.x, boundary.xMin, boundary.xMax),
0.0f,
Mathf.Clamp (GetComponent<Rigidbody>().position.z, boundary.zMin, boundary.zMax)
);
GetComponent<Rigidbody>().rotation = Quaternion.Euler (0.0f, 0.0f, GetComponent<Rigidbody>().velocity.x * -tilt);
}
}

 

hi again, I have moved on to the next tutorial boundary, it seems that the Shots are moving and being destroy by the bounding box but I can't see it move, it just stays in front of the ship until it gets destroy. Any clue is to why I can't see the shots animated forward ?

Thanks!

 

thank you very much for your help God Bless you always

 

When I start the Space Shooter ,there is a error existing.And I can not realise the meaning of it.
MethodAccessException: Method `UnityEditor.Analytics.AnalyticsSettings:get_enabledForPlatform ()' is inaccessible from method `UnityEditor.Analytics.AnalyticsImporter:<AnalyticsImporter>m__6 (UnityEditor.BuildTarget,System.Collections.Generic.HashSet`1<string>)'

I was getting the exact same issue but I solved by upgrading unity. Actually, there were more than 400 errors related to that analytics stuff and all those just gone by upgrading

 

Hey how do i make the game 3d?

 

-----------------------------------------------------
---------------------------------------------------------------------------------------------

Hi, in regards to unity_nOdYnMD6mmhwgQ's problem, I have the same problem and the same code as well at the same spot in the Space tutorial. I've also tried declaring the Rigidbody class variable as
---------
public Rigidbody rigidbody;

and implementing

rigidbody.rotation = Quaternation.Euler( ... etc.

instead of

GetComponent<Rigidbody>().rotation = Quaternation.Euler(... etc.


---------------------------
for example.

While this compiles, the problem is not fixed.

In the tutorial, rigidbody is built into Unity without the need for a Rigidbody deceleration. Do you know why this is, and if this has something to do with the problem. At the moment I haven't any idea other than this.

Also, are you getting your ship to move and to tilt with this script because I am not? Thanks.

 

So i am having an issue on 07 of the tutorial shooting shots..
so i got the code right as far as i can tell and it will fire when i want it to fire and i have "shot spawn" as a child for player
but it wont follow my ship.. it will continue to shoot from the transform position of 0, 0, 1.25

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. [System.Serializable]
5. public class Boundary
6. {
7.     public float xMin, xMax, zMin, zMax;
8. }
9.  
10. public class PlayerController : MonoBehaviour
11. {
12.     private Rigidbody rb;
13.     void Start()
14.     {
15.         rb = GetComponent<Rigidbody>();
16.     }
17.     public float speed;
18.     public float tilt;
19.     public Boundary boundary;
20.  
21.     public GameObject shot;
22.     public Transform shotspawn;
23.     public float fireRate;
24.  
25.     private float nextFire;
26.  
27.     void Update()
28.     {
29.         if (Input.GetButton("Fire1") && Time.time > nextFire)
30.         {
31.             nextFire = Time.time + fireRate;
32.             //          GameObject clone =
33.             Instantiate(shot, shotspawn.position, shotspawn.rotation); // as GameObject;
34.         }
35.     }
36.     void FixedUpdate()
37.     {
38.         float moveHorizontal = Input.GetAxis("Horizontal");
39.         float moveVertical = Input.GetAxis("Vertical");
40.  
41.         Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
42.         rb.velocity = movement * speed;
43.  
44.         rb.position = new Vector3
45.         (
46.             Mathf.Clamp(rb.position.x, boundary.xMin, boundary.xMax),
47.             0.0f,
48.             Mathf.Clamp(rb.position.z, boundary.zMin, boundary.zMax)
49.         );
50.  
51.         rb.rotation = Quaternion.Euler(0.0f, 0.0f, rb.velocity.x * -tilt);
52.     }
53. }

So i figured it out under the player controller script in the inspector view i must not of dragged "Shot Spawn" onto the shotspawn location to tell unity "Hey shoot from here" -_- well sleep does wonders lmao

 

------------------------------------------------------
Post Status: Issues Resolved.

So the issues I was having are sorted out now. Inside my PlayerController script, I was calling Fixed Update() as a nested call inside of the Update() call because I had my brackets out of sorts. I have the space ship moving and shooting though the shots couldn't be seen, because the quad sprite clones of Bolt were appearing orthogonal to the camera screen on the trigger press button call. So I redid that and fixed some other problems and now everything is functioning as it ought to.

 

What do i do if the platform web player in the build settings isn't there?

 

The web player has been deprecated a long time ago. You must build for WebGL instead.

 

Hello people. I know this tutorial is from time ago, but i just ended it succesfully. Except for one thing.
When it comes to the part of building the game, I´ve set the resolution on a round 600x900 as the tutorial says.
And it looks well on Game View. I also noticed the scale is set to 0.66 whenever I put that resolution as in the tutorial.




So does that scale have something related with the fact that, when I build the project with that resolution setting, the game looks zoomed on my default browser? Like this, in browser it only shows the Game Over Text, the upper part of the screen is cut off. But if I put the browser size on 67%(which i dont think it´s necessary at all) it shows up perfectly.



Anyone got a clue about how this happens or how to fix it? I´m interested on learning about UI so I can improve it on my games. Thanks in advance!!!

 

Hi there, I have been following this tutorial and was about to finish it, when I had to format my computer. Once I restored it, I installed by mistake the alpha version of Unity and running the project on the alpha version, well, weird behaviours started to pop.

I was able to get most of them working as they should except 1 thing, somehow, my ship, when reaching the boundary, gets out of the play area

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class playerMovement : MonoBehaviour
6. {
7.     public float speed = 0.0f;
8.     public float tilt;
9.     public Boundary boundary;
10.  
11.     void FixedUpdate ()
12.     {
13.         float moveHorizontal = Input.GetAxis("Horizontal");
14.         float moveVertical = Input.GetAxis("Vertical");
15.  
16.         var movement = new Vector3(moveHorizontal, 0.0f, moveVertical);
17.         var rigidBody = GetComponent<Rigidbody>();
18.         rigidBody.velocity = movement * speed;
19.  
20.         rigidBody.position = new Vector3
21.             (
22.                 Mathf.Clamp(rigidBody.position.x, boundary.xMin, boundary.xMax),
23.                 0.0f,
24.                 Mathf.Clamp(rigidBody.position.z, boundary.zMin, boundary.zMax)
25.             );
26.  
27.         //rigidBody.rotation = Quaternion.Euler(0.0f, 0.0f, rigidBody.velocity.x * -tilt);
28.     }
29.  
30. }
31.  
32. [System.Serializable]
33. public class Boundary
34. {
35.     public float xMin, xMax, zMin, zMax;
36. }

What I had found its that, the ship is moved out of the killBox area


Player left outside of the play are by the KillBox


This "killBox" es what I use to remove object that reach to it in order deactivate them in case they didn't collision with something else (an enemie, a bullet)

Code (CSharp):

1. using System.Collections;
2. using UnityEngine;
3.  
4. public class KillBox : MonoBehaviour
5. {
6.     void OnTriggerExit(Collider other)
7.     {
8.         Debug.Log(other.gameObject.name);
9.         switch (other.gameObject.tag)
10.         {
11.             case "Bullet":
12.                 //Debug.Log("A bullet reached the killbox");
13.                 other.gameObject.SetActive(false);
14.                 break;
15.             case "Enemie":
16.                 //Debug.Log("An Enemy reached the killbox");
17.                 other.gameObject.SetActive(false);
18.                 break;
19.             default:
20.                 Debug.Log($"{other.gameObject.transform.parent.gameObject.name} reached the killbox");
21.                 break;
22.         }
23.     }
24. }

Previous to using an alpha version, it wasn't giving me this behaviour. I'm currently on 2019.2.0f1

Making the killBox huge, well, this problem is no longer present, but then again, another one appears. If I enable the killBox box collider, the vertical movement is redenred slow, like, turtle slow. It moves like ignoring the speed modifier, until I also add horizontal movement, it moes normally

Any idea on why is this happening?

 

GUIText is not available in unity....only 3D text is available.......what else to use instead of that.... As GUIText is used in script also.....

 

Does anyone know how to spawn waves in a formation, like the most space shooter games today?

 

Is it possible to find the original Space Shooter assets somewhere? I'm trying to teach a class with this tutorial but the other free packs on the asset store have a lot of unnecessary features that get in the way a bit.

 

Looks like the tutorial has been "archived". (Which I'm guessing removes it from all searches, unless you have the URL, *or* search the archive? I've not yet looked into my theories.)

I had to google the tutorial, which is still online, with assets, here:
https://learn.unity.com/project/space-shooter-tutorial/?tab=materials

Good luck and best regards.

 

I Enrolled on a course at Udemy that requires me to download the Space Shooter Assets however they are no longer available, is there another way to acquire these?

 

Dear Spike-n-Art,

They've just been archived. (Apparently.) I googled the tutorial and I found this on this unity page, and sure enough there's a link to download it. However, it doesn't say "download". Underneath "Project Materials", click the link that says, "Space Shooter Asset Package"

Here's the page with all original files intact:
https://learn.unity.com/project/spa...6.1207864526.1577433549-1792668676.1539256790

Best regards,
Leland…

 

If you are looking for a copy of the assets (I cannot find them anywhere on Unity) I found this:
https://github.com/lukearmstrong/unity-tutorial-space-shooter

 

Hello! Please? how to import this pakage? Sory for my english

 

My apologies. You're correct. When I followed my link above, it leads to a "404" on the asset page.

@unity_17081986telefon, not sure, but I think you can you open two projects and then either copy/paste drag/drop between them, can't you?

Best of luck,
Leland...

 

Hi all,

The URL https://learn.unity.com/project/space-shooter-tutorial says the learning is no longer available.

I was able to download the project through unity and have uploaded to my GitHub.
https://github.com/Cyber-Technika/Unity-Space-Shooter-Starter

A YouTube series shows the learning process.
