Survival Shooter Q&A

Hello all once again, I am having a problem when it comes to scoring points after killing an enemy. I have put the scripts in the right places and have taken off the forward slashes in the Enemy Health script, but it is not giving me points when I test it. What is happening?

 

Anyone knows where is the CrossPlatformInputManager defined? Unity's own sample simply doesn't work and a search for this class fails miserably in the docs online.

 

It's in the Standard Assets Example Project. If you haven't downloaded it when you installed Unity, run the installer and select it in the installer window.

 

I did... that's the first thing I've checked out.

 

Thank you uni00 for asking this question and finding the solution I had exactly same problem, and I solved it by your method and it works like a gem!!

I am using unity 5.3 and I cant find the unity 5 package you were talking about, after searching thoroughly, I came to the conclusion that I already was using the unity 5 package..!
anyways, my game is working fine now, all thanks to u

 

I am using Unity 5.3, I have been doing just fine till it came to "Player Health" phase 6... my player wont get hurt, no matter how close the enemy gets...
there is these errors coming up: I havent touched the scripts, so there shouldnt be any issue...
Though I did try to play with it, I changed:

Code (CSharp):

1. GameObject.FindGameObjectWithTag("Player");

to

Code (CSharp):

1.  GameObject.Find("Player");

still no use..
I also tried to change the gameobject to public and assigned it in the fields, but it was no use...
I think it is this version compatibility issue..
what should I do? :/
anyone?

 

I've been seeing this error since I've started this project:

Assets/Standard Assets/CrossPlatformInput/Scripts/TouchPad.cs(41,17): error CS0246: The type or namespace name `CrossPlatformInputManager' could not be found. Are you missing a using directive or an assembly reference?

A lil help in fixing this would be greatly appreciated ^.^ I've only completed the first video so far, if that helps with how much I've done. I haven't messed with the scripts in any way. I'm also using unity 5.4. Thanks in advance!

 

This error message is about a script that doesn't belong to your project but to the the Standard Assets; remove them from your project; they are interfering.

 

what would be the safest way to remove it without derailing the project?

 

Removing them won't derail the project since they have nothing to do with it.

 

ok cool, thank you for your help! ^.^

 

I HAVE THE SAME ISSUE!! Someone please help

 

Changing my C# script to GameObject.Find ("Player").transform absolutely worked for me! Thank you very much!!

 

I keep getting the "All compiler errors have to be fixed before you can enter playmode!" error message even after I have fixed all the errors. The controller doesn't even pop up now. (I am working on the Player Movement phase)

*Edit* I missed something, which now lets me hit play, however I am getting this error:


ArgumentException: Input Axis horrizontal is not setup.
To change the input settings use: Edit -> Project Settings -> Input
PlayerMovement.FixedUpdate () (at Assets/Scripts/Player/PlayerMovement.cs:22)

 

Help please,

Im up to the harming enemy step and everything works as intended accept that when the bullet hits the enemy its health is unchanged and nothing happens, any advice

thanks

 

Is my camera messed up or is this a rendering error.

 

My animations start late. How can I fix this?

 

to answer PJSkittles 1st question : your camera seems messed up... my guess is that your player script might not be attached to the camera... or the player is not added to the "public gameobject" in the camera so it follows correctly... one thing to try is to exit play mode first, then open both the scene view AND game view, select the camera and check the settings in the inspector to make sure you can see the player... and that the script camera follow is correctly attached as well as the "player target" that needs to be dragged inside the script on the camera -- as for your animation late... i wouldnt know where to start as its pretty impossible to troubleshoot without having access to the actual project...


NOW for my own question : I am making an actual full commercial game (with 250 levels, 5 endless modes, 20 upgrades, etc...) I wanted to have some of the visual assets (models/environnement) from this game... i searched pretty much everywhere and it seems to be an open free liscence... meaning i can do whatever i want with it... is that correct? I wouldnt want to release my game and then get sued... Thank you for your time and have a nice day!

 

I just want to have a movement script without the animation. How much would I need to remove from the player movement script to get my desired result?

 

hi! I completed the tutorial and it works fine when launching from the IDE, either from mac and from linux. But when I try a webgl build, it fails, displaying a in-game console saying "Argument exception: the object you want to instantiate is null". there is no more information, and in the javascript console the stack trace is not human readable. the other symptom is that the bunnies did not appear. as I said, only happens in webgl..

 

Hello @ All!
I´m new here and i´m trying to create that shooter game with the Video Tutorial. I think my Problem is similar like Barney´s. I shoot the Zombunny a few times, an after that, the "shots" going trough the Zombunny and i can´t kill him. The Zombunny can hurt me an kill the player for a Game Over.

Also suprising for me is, that the Game starts after the Game Over, with everything complety coded and finished, with all characters and displaying Points, which i didnt code yet. Probably i imported the finished Game somehow.

 

I have been doing everything the tutorial says and everything seems to work fine so far but I am not sure on the lighting. I dragged the lights into the hierarchy like it said yet it doesnt look like what is shown in the tutorial videos




not sure if if there is something I missed of if I did something wrong

 

for some reason my zombear and hellephant spawners are not spawning anything I am not sure what I did wrong

 

I really need help like bad. My lighting is off and my zombear and hellephant spawners are not working even though I did everything correctly. I have tried everything I can think but nothing works and google has failed me

 

I export it as apk file, and I opened it with samsung note 5, the game doesn't have player movement controller, i can't move the character, what should i do?

 

Great tutorial. I completed it using Unity 5.3.4, everything worked like a charm. Few exceptions to the Code scripts which needed to be fixed in unity 5. Mainly the Application.loadLevel line in the playerHealth which I switched to SceneManager.LoadScene(SceneManager.GetActiveScene ().buildIndex);

Also had to load the SceneManager at the top of the script
using UnityEngine.SceneManagement;

the only other problem I noticed was the new event on the idle clip for the Zombunny which caused an error after the GameOver executes.

I do have 1 question. Where is the public function PlayerHealth.RestartLevel(); being called from to restart the level after GameOver?

Thank you
John Cordeiro

 

Added Death Particles to the Characters.

Create a empty child object under the character and name it DeathParticles.
Copy the DeathParticles Component from the Zombear prefab and paste it on to the newly created DeathParticles object.

Open EnemyHealth script, after the hitParticles variable add the following line.

ParticleSystem hitParticles; // Hit particle system reference
ParticleSystem deathParticles; // Death particle system

In the awake function setup the reference by adding the following line.
deathParticles = GetComponentInChildren <ParticleSystem> ();

Next add the following 2 lines to the Death function after the line anim.SetTrigger ("Dead");

deathParticles.transform.position = transform.position; // Set position of particles to hit point on enemy
deathParticles.Play(); // play death particles

Now when enemies die they will shoot out 2 buffs of stuffing as they die.

Hope this helps someone.

How do I stop all the enemies from spawning and and make them all die when the player reaches a certain score?

Stopping the spawning seems straight forward just disable the game object that contains the EnemyManager.

I am a little confused on how to disable all the enemies though.
I have added the following to the ScoreManager.

public int WinScore; // Score player must reach to advance to next level or wave.
EnemyHealth enemyHealth; // Variable to hold EnemyHealth

void Update ()
{
text.text = "Score: " + score;
if (score >= WinScore) {


enemyHealth.PlayerWins(); // Function to kill all enemies.

anim.SetTrigger ("NextLevel"); // Play next level animation on HudCanvas.

}
}

I have an Idea of how to proceed but wanted to get some advice first.
In the enemyHeath I was planning on creating a new public function named PlayerWins();

There I would basically copy the IsSinking block and add in the death animation so they enemies die and then sink.

Any Advice is greatly appreciated.
Thank you

Greetings all. In short, I did this tutorial when I first started learning Unity and hit a snag. Couldnt solve it. Now, after I felt much more confident I revisited it but have hit the same snag and cant find a solution.

My zombunny wont move toward the player. It simply walks in place. I have ensured my player has been tagged as "Player" as called for in the enemymovementscript.cs and I have tried countless baking configurations. Buckner was kind enough on another site to mention the change to the step height being 0.35 but that didnt solve it. I thought maybe it was applying root motion as that has visually has the same effect as I am experiencing but that didnt work either. Lastly, I opted to use all of the provided script assets to ensure I wasnt mistyping anything and still have not gotten the little guy to follow. Anyone else having this problem? Suggestions?

Thank you so much in advance for your time!

 

Hey Guys i made the game but i dont know how to add mobile controls or a joystick?Can some body help me?Thank You!

 

Great idea John! This came to mind:
public class ScoreManager : MonoBehaviour
{
public int score;
public bool won;
public int winScore;

Text text;

void Awake ()
{
text = GetComponent <Text> ();
score = 0;
won = false;
}

public void ChangeScore( int change )
{
score += change;
text.text = "Score: " + score;
if ( score >= winScore )
{
won = true;
}
}

void Update ()
{
// Moved to ChangeScore so it doesn't happen every frame.
}
}

Note that this was also re-arch'd to implement ChangeScore as a function, rather than directly manipulating the score - that way I can do "things" on a change. I also set it this way so the score could be decreased just-in-case. I moved the code out of Update, so it's happening only when the score changes, not 30+times a second (?).

This change also required this:
...private member...
ScoreManager scoreManager;

void Awake ()
{
anim = GetComponent <Animator> ();
enemyAudio = GetComponent <AudioSource> ();
hitParticles = GetComponentInChildren <ParticleSystem> ();
capsuleCollider = GetComponent <CapsuleCollider> ();
scoreManager = GameObject.Find("ScoreText").GetComponent<ScoreManager>();

currentHealth = startingHealth;
}


void Update ()
{
if(isSinking)
{
transform.Translate (-Vector3.up * sinkSpeed * Time.deltaTime);
}

if (scoreManager.won && isDead == false )
{
Death();
}
}

This works for me, and I think is somewhat robust. The call to Find is pretty expensive, but I'm thinking it's less expensive than the updating of the text every frame (though that could be fixed a different way). You could re-build my changes to include more statics, if you prefer, of course! What ever best works for you.

Also make sure you add currentHealth = 0; in the Death function. So that EnemyMovement works properly.

Note that this is missing the changes to the spawing of enemies, who will continue to spawn, and promptly die.

I think these changes "fit" the original design pretty well.

Good luck!
Q

 

Can someone help me fix this error please

 

Hello, I have the same problems.
I set "Interruption Source" to "Next State", and now it does play Move animation when I move the player.
I wonder whether it is a correct way to fix my problem.
However, the problem that Idle animation gets stuck still exists -- if Idle animation finishes and I'm not moving the player, it gets stuck and no animation is shown.
Thanks for any help!

 

Did a bunch of searching to figure out why my character wasn't moving at all after the end of lesson two and finally figured out the solution. Somehow I forgot to attach the script to the player! I simply dragged the PlayerMovement Script from the project file to the hierarchy for player and presto! Just in case someone else ran into this. Also, thanks to all of the people who watch this forum and try their best to answer some of the crazy scripting issues people run into. You guys are great.

 

Are you missing the opening bracket? Post all of your code. Here is a quick explanation of how to post code:

Hello again, I have finished the survival shooter and I am trying to post it to a certain site but I need to convert it to either an EXE or html5 folder and need help with how to convert it.

 

On "Creating Enemy #1", Zombunny does not seek out player. It stands in the same place continuously performing the walk animation. I've restarted this section of the Tutorial 3 times. Tried copying the code over exact. Using Unity site tutorial + transcript + updated pdf. Tried all the responses I've found on this forum (and youtube) including making sure Floor is set to Static, making sure player is tagged as "Player", using "GameObject.Find" instead of the original code suggested, nothing seems to work.

The player can push around the Zombunny but it doesn't move and continues to performing walk animation.

Using Unity 5.4.1f1. I have seen this issue in several versions but none so far directly for 5.4.1 posted yet. Here's a couple screens and the copied over code;

Hey all, ive read about 4-5 pages and seen issues with stage 2- movement pop up alot but nothing i tried could fix it.

Above you can see my code (i swear i've checked it near word for word but cant see the forest for the trees) and above that the screenshots of the errors.

If i copy and paste the code from the tutorial page i am able to move, BUT i still get loads of errors pop up regardless. So at least i know my movement issue (which is my main concern anyway) is a problem in my script.

Ive been looking at it for so long its all blurred into one thing, anyone able to spot what i can not?
​

 

From what I can gather, your shooting script is on the player game object instead of the gun and the awake method in your movement script needs to be Awake with an uppercase A.

Edit: shooting script goes on the gun, not gun barrel

 

Ah, not on the shooting bit yet but thanks for the heads up, moved that script over.#


And movement works now. I can not BELIEVE thats what caused my movement problems

I'm still getting errors about line renderer, but so far the tutorial hasnt told me to add line renderer so im assuming seeing as it moves as it should be, i'm ignoring it for now

 

I noticed someone else was having this problem too.

I face palmed when i realized what i did wrong.

In the camera follow script check the void start function thoroughly. A small spelling mistake in there caused this for me.

 

So, I am the only one that downloaded the asset and was not able to find both the Zombear and the Hellephant prefabs? (and by that I mean the one that are edited in the tutorial, not those the the Completed folder)

 

Can anyone help me with this?

 

No, I believe that this is a problem with the latest release of the assets/and or version 5.4.1f. I have several different versions of the Survival Shooter assets and only the latest one doesn't have the Hellephant and Zombear prefabs. I also have students that only have version 5.3 and they have the prefabs. I have yet to get to this point with my students, but I'll be tempted to grab the completed asset version and swap out the right components.

 

For those that are trying to get the shooter to run in the Daydream preview, I just managed to do it (partially). I posted my results (step by step) in the Daydream forum.

If you are running the tutorials, you are creating the floor layer. Please replay the environment tutorial.

 

There is a script in the Completed folder in the there Script/Manager folder, I would direct you there to the PauseManager.cs for some guidance.

 

Hello everyone,
I have done the whole tutorial and found it helpful, but for the last phase - Game Over. It won't reload my scene that I created, it keeps on loading there completed scene.

 

I figure it out in the SceneManager.LoadScene() in the PlayerHealth.cs, change the '0' to '1'.

 

Actually a better solution is to go Build Settings, uncheck the Complete Scene and add the current scene.
