Survival Shooter Q&A

It looked like lots of people had a issue at animation problems in phase 2.
I just fixed it.
All you have to do is go to the two transition between "Idle" and "Move". Select them and disable the "Have exit time"
Then Everything is fine.

 

One for the guys when they get back, but in general as far as i've read, the majority of unused items in the heirarchy wont be included in the build.
Heres a page to have a look at for more info in the mean time.
http://docs.unity3d.com/Manual/ReducingFilesize.html

 

What exactly are you having problems with? and can you explain what is not the same or what errors you are getting.

Need a bit more information to help out.

 

Have you found a solution yet? This is strange to me too.

 

Hey guys, I'm on Unity 5.3.4

GameObject.FindWithTag("Player").transform
returns:
Player(Clone) (UnityEngine.Transform)
UnityEngine.MonoBehaviourrint(Object)

and position is empty (0,0,0)
but
GameObject.Find("Player").transform
returns:
Player (UnityEngine.Transform)
UnityEngine.MonoBehaviourrint(Object)
gives me proper, players position.

I do have "player" tag on "player" object. Why is that happening ?

 

I'm having an issue where, when I have enemies spawn, they get stuck behind walls and can't leave the spawn point. I've also tried simply placing an enemy next to the player; when I click play, though, the enemy defaults onto the nearest elevated surface (such as the top of the stool or dresser) and can't move off to get to the player. I'm don't have any clue where I messed up.

Solved.

 

When your using the

Code (CSharp):

1. GameObject.FindWithTag("Player").transform;

make sure that your player, has the exact same tag assigned (case sensitive) as you are searching for, ie "Player".

I take it there is only one player in the Scene? just that FindWithTag will only return the first object with that tag it finds.

 

Have another look at the navigation section, when looking at the navmesh, sounds like the floor isnt part of the static mesh?
http://unity3d.com/learn/tutorials/projects/survival-shooter/enemy-one?playlist=17144

should be able to see the floor as the light blue color same as they have in the video.

 

@Umbra1 You helped me a lot! Thank you!
More specifically, in 'Object' tab of 'Navigation' window, select 'All' filter, then check the items in 'Environment' GameObject one by one, the 'Floor' item's 'Base', 'Planks' and 'Sides' are 'Navigation Static' unchecked, so check them on will solve the problem.

 

Uh, guys? I just realized my UI Slider does not look like the one in the videos. Also, the slider is very glitchy! Whenever I choose some other options for the fill rect and the handle rect, sometimes it responds to the changes. However, whenever I change the options again, sometimes it doesnt respond to the changes. My slider is very glitchy!

 

Forgive me if I missed the answer to this, but does anyone have info on where to get the "MenuCanvas" mentioned in the final upgrade lesson video? I looked throughout the 8 pages of this thread as well as everywhere else I could think of on the internet, but to no avail. I've seen others ask about it but I haven't seen any answer. I looked through all the Assets, and I'm using the most recent download of the Asset package. I also tried all the "links below" that the video mentioned, but they didn't have the answers either.

Also I encountered a lot of similar problems to others and wanted to suggest a perusal of the upgrade guide included in the root folder of the downloaded assets. Finally, thank you jaimemh and rePhat for your comments! They helped a lot with my lighting problem.

 

When I following the Survival Shooter Tutorial Phase 4, the enemy is missing for being placed higher than floor. I found that the "Navigation Static" flag of "Floor" in the "Environment" has not been checked. It works after fixed.

 

If you write your problem clearly, we will try to solve

 

In the 7th series of Survival Shooter.

Survival Shooter Tutorial - 7 of 10 : Harming Enemies
There is a public method which is called StartSinking in EnemyHealth script.
See below:

Code (CSharp):

1. public void StartSinking ()
2.     {
3.         GetComponent <NavMeshAgent> ().enabled = false;
4.         GetComponent <Rigidbody> ().isKinematic = true;
5.         isSinking = true;
6.         //ScoreManager.score += scoreValue;
7.         Destroy (gameObject, 2f);
8.     }

You know, we delete EnemyObject after Sinking. Why do we need to write these two codes(see below) in spite of the fact that we delete EnemyObject.

Code (CSharp):

1. GetComponent <NavMeshAgent> ().enabled = false;
2.         GetComponent <Rigidbody> ().isKinematic = true;

 

Why are these gameObjects different color which are black and blue.

 

I want to call a public method in Animation Event. However, my obejct does not have animation like ZomBunny.
This picture explain my problem. See below:

 

Anyone having ISSUES with the Environment? (Floor)
Such as ZomBunny / ZomBear walking / moving but not following your main character but Animation on them is showing,
just not Following like Stuck in a spot. (even in High Areas)???

SOLUTION:

1) go to WINDOW up top, then click NAVIGATION.
2) NOW in the NAVIGATION window make sure OBJECT is selected.
3) click MESH RENDERERS just below OBJECT.
4) Now in the HIERARCHY panel, look for PLANKS and click it.
5) Now back in the NAVIGATION panel you need to click the check box for
NAVIGATION STATIC!

Now the Enemies will follow and walk on the surfaces needed
for the game to actually work.

Hope this helps... I'm new to game development and design so learning myself.

hello everyone! i tried to fix some problems with the environment, and i found a solution.
in unity 5.3.5f1 i have a bug with floor, like this:


it can be fixed, if you set environment -> floor to static, in the inspector:



but, when i done this, i received this bug:



i use this settings for Bake:



if you have the same problem, all you need to do is follow unity instructions: divide agent radius into four. (in my case 0.75 / 4 = 0.1875)
when i set voxel size to 0.1875, this solved my problem:

 

Hi,

I'm having with Phase 2 of the lesson. I have followed the scripts for player movement and all are well.
When i try to move the character it glides off instead of umping, after a few second it starts to move.
After going through the forum, i saw that i just have to unchecked the "has exit time" in animation tab. Instead now it the complete opposite. My character starts jumping and it doesnt stop when my character is idle, only after a certain period of time that the idle animation will play

 

I have the same bug. I uncheck 'has exit time' in move -> idle and any state -> death. it works for me.
maybe you need save a scene before test, or even reboot editor to apply these changes.

 

I'm having a problem animating my player. The walk and death animations do nothing to the player itself despite having unclicked the "has exit time" box and making sure the PlayerAC is attached to the Player appropriately. Now here's the weird part: the gun is animated just fine. It bounces as the character moves and falls when it dies, but the player model itself never changes. Does anyone have any potential solutions? I would REALLY appreciate it

 

This got me close to a solution, but notice there are still weird things going on. Namely a little south to the fire truck there's a dip in the planks that doesn't get "navmeshed", then south of the doll arm, a plank crack/spacing, south of the desk another crack/spacing and finally near the mouse hole again a plank. I'm sure this could be considered nitpicking but playing with slope or any other settings doesn't get me a full floor. Does anyone know why this happens?

 

Okay this might be cheating but here's what I did (and I'm quite new at all of this so if someone has a better or cleaner method than by all means let me know!):

1. After getting through the first upgrade lesson, save the scene and open a new scene
2. Open the scene found in the _CompletedAssets folder called "Level 01 5.x.unity"
3. In that scene, the MenuCanvas game object exists, drag the parent object into your prefabs folder
4. Close out of that scene, no need to save, and reopen your tutorial scene
5. Drag your prefab MenuCanvas into the hierarchy, and disconnect the prefab instance
6. In _CompletedAssets/Scripts/Managers, move the "Pause Manager" script into your Scripts Folder
7. Move the _CompletedAssets/Scripts/Audio folder into your Scripts Folder
8. In the Inspector for MenuCanvas, for the Pause Manager component, circle-select your AudioMixerSnapshots
9. In the Mix Levels component, also circle-select the MasterMixer audio mixer you made in the tutorial
10. (Unnecessary step) I also saved/closed, moved my _CompletedAssets folder in Windows, and confirmed that the scene still worked with the new MenuCanvas game object. The fact that it worked meant there were no lingering assets that I hadn't created myself needed to run the pause menu

I seriously would love a tutorial on how to actually make this pause menu though, instead of just moving a game object into my project. So if anyone finds that then I'd be happy to know about it.

 

I tested enemies movement near the fire truck and the doll arm, and it working fine (enemies walk through this areas), even despite there a dip in the planks.

 

Hi,

I did the reverse and now I know how to make an environment; I can carry on with this tutorial then!

 

Hi,

So far, so good but I have a question. How could I modify the PlayerMovement script and add mouse look to it?

Spoiler: PlayerMovement script

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerMouvementScript : MonoBehaviour
5. {
6.     public float speed;
7.  
8.     Vector3 movement;
9.     Animator anim;
10.     Rigidbody playerRigidbody;
11.     int floorMask;
12.     float camRayLength = 100;
13.  
14.     void Awake ()
15.     {
16.         floorMask = LayerMask.GetMask ("Floor");
17.         anim = GetComponent<Animator> ();
18.         playerRigidbody = GetComponent<Rigidbody> ();
19.     }
20.  
21.     void FixedUpdate ()
22.     {
23.         float h = Input.GetAxisRaw("Horizontal");
24.         float v = Input.GetAxisRaw("Vertical");
25.         Move (h, v);
26.         Turning ();
27.         Animating (h, v);
28.     }
29.  
30.     void Move (float h, float v)
31.     {
32.         movement.Set (h, 0.0f, v);
33.  
34.         movement = movement.normalized * speed * Time.deltaTime;
35.  
36.         playerRigidbody.MovePosition (transform.position + movement);
37.     }
38.  
39.     void Turning ()
40.     {
41.         Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);
42.  
43.         RaycastHit floorHit;
44.  
45.         if (Physics.Raycast (camRay, out floorHit, camRayLength, floorMask))
46.         {
47.             Vector3 playerToMouse = floorHit.point - transform.position;
48.             playerToMouse.y = 0.0f;
49.  
50.             Quaternion newRotation = Quaternion.LookRotation (playerToMouse);
51.             playerRigidbody.MoveRotation (newRotation);
52.         }
53.     }
54.  
55.     void Animating(float h, float v)
56.     {
57.         bool walking = h != 0.0f || v != 0.0f;
58.         anim.SetBool ("IsWalking", walking);
59.     }
60. }

Hey there I've got a problem with step 10. I am running Unity 5.3.4.
I followed everything and it all works except the GameOver Text is there throughout the game rather than just at the end.

I attached the gameover script and a print screen of unity.

 

maybe you need set GameOverText color alpha to zero

 

Ahh I saw what I did, I set the effect alpha color to zero instead of the text alpha color to zero. Thank you.

 

Hello!

In the video there is a large flash in front of the gun barrel, presumably from the gunLight. In my version the laser line works fine every time I shoot, but the large flash only appears once. After shooting one time, it doesn't work again. Can someone suggest what I missed in the setup or what settings I should check?

Thank you

 

Hi,

I am trying the make a navmesh for the environment in Unity 5.4, but I can never make the proper navmesh. I tried the parameters in the update PDF for Unity 5 and several of other values in the forum, but the consequences were always same as in the enclosed. As you can see, no nevmesh on the floor, but only small spots on the top of obstacles.

Can anyone suggest any solution? I have been stuck at this problem for 5 hours so far...

Thanks in advance.

Hi all can AnyOne Help me on with score Board Iam useing unity 1.5 and thets the script on the scoremanager: http://pastebin.com/JKX1m2ET


this effect on EnemyHealth http://pastebin.com/B4ULbuH6

 

i can help u watch this one http://unity3d.com/learn/tutorials/topics/navigation/navmesh-baking

 

Thanks for the suggestions, money4honey. I had been using my computer all day when i was getting that issue. When I started up my laptop fresh this morning I got a few gunLight flashes before it stopped working. So i put some code on the Update() function to check what's going on.

Code (CSharp):

1. void Update ()
2.     {
3.         timer += Time.deltaTime;
4.  
5.         if(Input.GetButton ("Fire1") && timer >= timeBetweenBullets && Time.timeScale != 0)
6.         {
7.             Shoot ();
8.         }
9.  
10.         if(timer >= timeBetweenBullets * effectsDisplayTime)
11.         {
12.             DisableEffects ();
13.         }
14.  
15.         if (gunLight.enabled == false)
16.         {
17.             print("gunLight disabled");
18.         }
19.         else
20.         {
21.             print("gunLight ENABLED");
22.         }
23.  
24.     }

I can see the gunLight being ENABLED/disabled. My laptop has an Intel HD 520 graphics card and doesn't slow down while playing so this is definitely weird, but not the end of the world. Inconsistencies are annoying

 

I'm at a complete loss; I cannot get the EnemyAttack script to work. I'm getting two error messages:

• NullReferenceException: Object reference not set to an instance of an object
  EnemyAttackScript.Update () (at Assets/_Scripts/EnemyAttackScript.cs:49)
• NullReferenceException: Object reference not set to an instance of an object
  EnemyAttackScript.Attack () (at Assets/_Scripts/EnemyAttackScript.cs:59)
  EnemyAttackScript.Update () (at Assets/_Scripts/EnemyAttackScript.cs:46)

Okay, the problem is not with the script; it compiles perfectly, but with the Zombunny. It seems to be missing something but I have no idea what.

 

You can check the Complete folder. There is a finished Zombunny prefab and EnemyAttackScript. This may help you figure out what wrong with your project.

 

Thanks. I did take a look and I didn't see any difference, so, I trashed the entire project. I'm remaking it from scratch now.

I should have edited or deleted my post, sorry.

 

My Zombunny works fine, but both Zombear and Hellephant are 1) not taking damage and 2) not attacking my Player. I used Debug.log to ascertain that my playerHealth is null, even though my player object is non-null. I really don't understand how this is possible because all 3 enemies are set to the same Player, yet playerHealth is non-null for Zombunny but null for the other two enemies (since I can receive and apply damage to Zombunny fine, but cannot do either for the other two enemies).

Solved my own problem. For the Enemy Manager components for my Zombear and Hellephant I was using, in the "Enemy" field, Zombear and Hellephant gameobjects from the _CompletedAssets Prefabs folder instead of the Assets Prefabs folder. I am curious how the Enemy Manager works however... can it only "see" the Player instance if the Player prefab is in the same directory as the Hellephant prefab? Why can't you see a Player instance if the Player prefab is in a different folder?

 

How were the Player and Enemy animations created for this tutorial? For example, Idle, Move, Death. Were these done in Unity or a 3rd party program (if so, which?)?

 

I think it was a third party. Unity has no making animation thingy, you have to get an "external application" for artwork. Unity probably used something called Maya.

 

2 Questions folks:

1. why does the player shoot when the game is paused

2. why doesn't the game quit when I click quit?

weird... when I build the game the enemies follow and attack the player and everything is fine( except for the fact that the game doesn't restart and I can't quit the game). In the scene, however, the enemies don't attack the player .

I think so. Not sure...

 

So, I've redone the project up to where I was when I trashed it and... it's now working great! Yeah!

 

happy for you . you are sure that nothing is missed, when you did it last time? maybe you use new beta editor? I heard there might be some bugs

 

Something was probably missing but I've never found out what it was and, no, I'm not using the beta; I'm not that adventurous. I'm using 5.3.5f1 Personal edition.

It's working, okay, but, I'm getting that message in the console, after playing the game:
