Why the sound effect does not work in unity?
when I try to add a sound effect, it doesn't work
This is my script to move to the next scene using buttons:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class LevelLoader : MonoBehaviour
{
public Animator transition;
public float transitionTime = 1f;
public void LoadNextLevel()
{
StartCoroutine(LoadLevel(SceneManager.GetActiveScene().buildIndex + 1));
}
public AudioClip impact;
IEnumerator LoadLevel(int LevelIndex)
{
transition.SetTrigger("Start");
yield return new WaitForSeconds(transitionTime);
SceneManager.LoadScene(LevelIndex);
AudioSource.PlayClipAtPoint(impact, transform.position);
}
}
You're making the audio play, and then immediately loading in a different scene. The object that is playing the audioclip also unloads.
You could offset the two by making NewGame() a coroutine instead, with a small timed offset between the PlayClipAtPoint() call and the LoadScene() call.
As Alex Leest said, you are loading new scene right after audio play.
When unity scene loading started, all gameobject except DontDestroyOnLoad Object are destroyed.
So, you may add code below to your Audio Manage class.
(Also, you should ensure that your Audio Manager class always has only one instance in your whole program for not cause bugs)
private void Awake()
{
DontDestroyOnLoad(this);
}

So I'm using this code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class wands : MonoBehaviour
{
public Transform WandPos;
void Update()
{
WandPos.rotation = Quaternion.Lerp(new Quaternion(0,0,1,0), new Quaternion(0,0,0.866025448f,0.49999994f),Time.time * .5f);
}
}
For some reason it is preforming the rotation before the GameObject even rotates, so when it instantiates, the GameObject snaps to where it would be if it instantiated when the scene started. I'm probably just missing something obvious, but I can't seem to find my solution anywhere online either.
Also, if there is an easier way to do this than with the code I've written, please tell me.
Well Time.time is the time in seconds since you started the application!
Sounds like you rather wanted to track the time since you instantiated the object so e.g. like
private float time;
void Update ()
{
time += Time.deltaTime * 0.5f;
WandPos.rotation = Quaternion.Lerp(new Quaternion(0,0,1,0), new Quaternion(0,0,0.866025448f,0.49999994f), time);
}
When I retrieve an object from a list of created objects and reactivate it, it destroys itself, but only if I have force applied to start it moving. If I never apply force, everything works as intended and I can keep activating the object over and over.
I've tried putting a debug.log in the OnCollision and it isn't colliding with anything.
As said above, if I never initiate speed, the rest works fine.
When speed is applied, the first projectile works, the second destroys itself.
I've tried manually activating them instead of by code. Same result.
Exception: If I manually activate/deactivate objects myself through the inspector, they work if I only have 1 shot in the pool.
The one shot rule doesn't work if I do it through code. It breaks even if I only have one shot.
All the code worked when I wasn't using pooling.
Spawn code:
void CreateBullet(int GunID)
{
GameObject ShotFired = Guns[GunID].GetComponent<Weapon>().FireWeapon();
if (ShotFired == null)
{
ShotFired = Instantiate(Guns[GunID].GetComponent<Weapon>().Projectile,Guns[GunID].gameObject.transform);
Physics.IgnoreCollision(ShotFired.GetComponent<SphereCollider>(), Guns[GunID].GetComponentInParent<CapsuleCollider>());
Guns[GunID].GetComponent<Weapon>().AmmoPool.Add(ShotFired);
}
ShotFired.transform.position = Guns[GunID].transform.position;
ShotFired.transform.rotation = Guns[GunID].transform.rotation;
ShotFired.SetActive(true);
}
Projectile Code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Mirror;
public class Projectile : NetworkBehaviour
{
public float Speed;
public float LifeTime;
public float DamagePower;
public GameObject ExplosionFX;
// Start is called before the first frame update
void Start()
{
GetComponent<Rigidbody>().AddRelativeForce(Vector3.up * Speed, ForceMode.VelocityChange);
StartCoroutine(DeactivateSelf(5.0f));
}
private void OnDestroy()
{
Debug.Log("WHY!");
}
IEnumerator DeactivateSelf(float Sec)
{
yield return new WaitForSeconds(Sec);
Explode();
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.GetComponentInChildren<Vehicle>())
{
collision.gameObject.GetComponentInChildren<Vehicle>().CmdTakeDamage(DamagePower);
}
Explode();
}
void Explode()
{
GameObject ExplosionEvent = Instantiate(ExplosionFX, this.transform.position, Quaternion.identity);
NetworkServer.Spawn(ExplosionEvent);
GetComponent<Rigidbody>().AddRelativeForce(Vector3.zero);
gameObject.SetActive(false);
}
}
Any thoughts welcome. Thanks in advance!
In case anyone else stumbles across this, here's what happened and why assigning a movement speed to the object was what caused the issue.
My projectiles had a 'trailrenderer' on them.
By default 'Autodestruct' is true.
Autodestruct does not destruct the trail, but the game object when the trail disappears. So if you disable anything that had a trail, and activated it through movement, when the object stops moving (say to reposition in an object pool) it will destroy the parent object.
If the object never moves, it never generates a trail, and never needs to be destroyed.
To fix, just uncheck autodestruct.

When I start to play , it can't jump to the next scene .It also pumps out many error ,one error repeats many times , Coroutine couldn't be started because the the game object 'FadeOut' is inactive!It made me confused since the rawimage is all black and must be inactive before the function onclick.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;
public class ToLoading : MonoBehaviour
{
public Button toLoad;
public RawImage fadeOut;
public Text loading;
// Start is called before the first frame update
void Start() //need to SetActive(false); ? if I set it false already in unity
{
}
// Update is called once per frame
void Update()
{
ButtonClicked();
}
public void ButtonClicked() //
{
fadeOut.gameObject.SetActive(true);
loading.gameObject.SetActive(true);
StartCoroutine(ToNextScene());
}
//going to do: fade out> 2 secoonds > to next scene
private IEnumerator ToNextScene()
{
yield return new WaitForSeconds(2);
SceneManager.LoadScene("SceneForMovingAround");
}
}
My question is : Should I put this script ToLoading to the fadeout rawimage ,or create an empty gameobject then put the script to it .Also , how to solve the problem -fade out error.And last , will it a problem about the code of scene part ?all of your help is appreciated, thanks!
Your ButtonClicked() method is executed every frame, which causes the unwanted behaviour your describe.
Remove the entire Update() method with its body from your file and run your game again.
Add gameObject.SetActive(false); to your ButtonClicked() method to deactivate the button upon clicking.
If you have attached the ButtonClicked() method to the OnClick() event in the inspector as you show in your screenshot then it should work as you would expect.
I am making a game now, it's almost done. now I am trying to control the audio on and off by button or toggle button.
The problem is, I put my audio source gameobject in the splashscreen that is in the 1st scene. and I put the audio or music button in the Setting scene which is inside the 3rd scene. I already make the c# script to control the audio but when I've tried to insert the AudioSource, but it can't since it's from a different scene. I've tried to put the AudioSource in the same scene but the audio didn't start except I go to settings scene first.
Here is the script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Music : MonoBehaviour
{
static Music instance = null;
public AudioSource Backsound;
private void Awake()
{
if (instance != null)
{
Destroy(gameObject);
}
else
{
instance = this;
GameObject.DontDestroyOnLoad(gameObject);
}
}
public void backsoundOnOff()
{
AudioSource bgsound = Backsound.GetComponent<AudioSource>();
if (bgsound.mute = true){
bgsound.mute = false;
}
else {
bgsound.mute = true;
}
}
}
You have already solved half the problem by using GameObject.DontDestroyOnLoad
The object does indeed exist in both scenes. Now you just need to fetch it.
In the first scene where the created the object, Change the tag of the object. Instead of using one of the exiting tags, create a new tag for it called something such as "MenuMusic". Make sure you assign it after creating it, unity does not assign it automatically
Now, in the 3rd scene, in the game object that needs to access it, create a private field "_music"
in your Start function, add
void Start() {
_music = GameObject.FindGameObjectsWithTag("MenuMusic");
}
You will now have the same instance of Music from scene 1
I would highly recommend referencing the sound script that you have into some sort of game manager. Usually how i work is i have one generic script that controls a multitude of options that i usually call the GameManager. This sets player controls, visual options and sound. From here you can simply set bool whether the player wants the music on and off. If this option wants to change you can reference the GameManager at any point in any script.
//Game Manager code
public void SoundControl(bool soundOff)
{
If(soundOff == true)
{
//Sound Off Control
}else
{
//Sound on Control
}
}
//Reference to game Manager
GameManager manager;
public void TurnOffSound()
{
//Turn sound off through manager
manager =
GameObject.FindGameObjectWithTag("Manager").GetComponent<GameManager>
().SoundControl(true);
}
I find this to be the easiest way to control any options through one script that you can reference anywhere.
I'm trying to make the system work so that when a game starts and for each wall, it will either be in the game or not, randomly. Somehow, when I run it, it either keeps or destroys all the walls. How do I fix this?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class WallGen : MonoBehaviour{
public GameObject wallObject;
System.Random rnd = new System.Random();
// Use this for initialization
void Start () {
generate();
}
void generate()
{
int number = rnd.Next(1, 5);
if (number == 2)
{
OnDestroy();
}
}
private void OnDestroy(){
Destroy(wallObject);
}
// Update is called once per frame
void Update () {
}
}
Every time you do new System.Random() it is initialised using the clock. Now as the Start function is called at the same time, you get the same value for all the gameobjects. You should keep a single Random instance for all gameobjects and keep using Next on the same instance.
Or the easy solution
just Use Random.Range (1,5) instead of rnd.Next(1, 5);
As a side note, don't use the function name OnDestroy, as it is one of the MonoBehaviour functions in Unity and is called automatically when the attached gameobject is destroyed.
