I writing simple game on Unity (C#)
I have player and want to make the destroyer, that will destroy player.
I create prefab of destroyer. And next, I create Quad.
I have spawn script:
using UnityEngine;
using System.Collections;
public class SpawnScript : MonoBehaviour {
public GameObject[] obj;
public float spawnMin = 1f;
public float spawnMax = 2f;
// Use this for initialization
void Start () {
Spawn();
}
void Spawn()
{
Instantiate(obj[Random.Range(0, obj.GetLength(0))], transform.position, Quaternion.identity);
Invoke("Spawn", Random.Range(spawnMin, spawnMax));
}
}
Also I write DestroyerScript:
using UnityEngine;
using System.Collections;
public class DestroyerScript : MonoBehaviour {
void OnTriggerEnter2D(Collider2D other)
{
if (other.tag == "Player")
{
Application.LoadLevel(1);
return;
}
if (other.gameObject.transform.parent)
{
Destroy(other.gameObject.transform.parent.gameObject);
}
else
{
Destroy(other.gameObject);
}
}
}
My destroyer spawning, but when player get it, I don't have Game Over screen.
Add rigid body to both player and "player destroyer" and then set onTriggerEnter on your player destroyer like so:
void OnTriggerEnter(Collider other) {
Destroy(other.gameObject);
}
For some fine tuning, you can do some checks if the other object is in fact the Destroyer (you can compare the tag or something, I won't go into too much detail now).
EDIT: Uncheck "isTrigger" on your BoxColliders and try this:
void OnCollisionEnter (Collision col)
{
Destroy(col.gameObject);
}

So i have this little particlesystem attached on my player so if he dies he explodes. But i cant simply attach the particlesystem under the player because if i destroy my player the childs of the gameobjects get destroyed as well. The animation runs if he dies but not on his current spot so some ideas for that? Maybe to transform the position to the current position of the player while he dies?
Here my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class playerdeath : MonoBehaviour
{
public ParticleSystem death_explosion;
// Start is called before the first frame update
void Start()
{
death_explosion.Stop();
}
// Update is called once per frame
void Update()
{
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "deathcube")
Destroy(gameObject);
Debug.Log("collision detected");
death_explosion.Play();
}
}
What you could do is create a prefab of the particle object and reference it inside your script like so:
public ParticleSystem death_explosion_Prefab;
And instead of attaching it to the Player as a child, instantiate it on collision:
void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "deathcube")
{
Debug.Log("collision detected");
Instantiate(death_explosion_Prefab, gameObject.transform.position, Quaternion.identity);
Destroy(gameObject);
}
}
got it :) --> add death_explosion.transform.position = GameObject.Find("player").transform.position;
so I’m trying to create a respawn system as a beginner, and everything seems to be working the first time but the second time it seems to be unbehaving. If anyone knows how to help me, I would appreciate it
LevelControl:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
public class LevelControl : MonoBehaviour
{
public int index;
public string levelName;
public GameObject GameOverPanel;
public static LevelControl instance;
private void Awake()
{
if (instance == null)
{
DontDestroyOnLoad(gameObject);
instance = GetComponent<LevelControl>();
}
}
void OnTriggerEnter2D(Collider2D other)
{
if (other.CompareTag("Player"))
{
//Loading level with build index
SceneManager.LoadScene(index);
//Loading level with scene name
SceneManager.LoadScene(levelName);
//Restart level
//SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
}
}
public void LoadLevel1()
{
SceneManager.LoadScene("Game");
}
public GameObject GetGameOverScreen()
{
return GameOverPanel;
}
}
PlayerMovement:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public CharacterController2D controller;
public float runSpeed = 40f;
float horizontalMove = 0f;
bool jump = false;
bool crouch = false;
// Update is called once per frame
void Update()
{
horizontalMove = Input.GetAxisRaw("Horizontal") * runSpeed;
if (Input.GetButtonDown("Jump"))
{
jump = true;
}
if (Input.GetButtonDown("Crouch"))
{
crouch = true;
}
else if (Input.GetButtonUp("Crouch"))
{
crouch = false;
}
}
void FixedUpdate()
{
// Move our character
controller.Move(horizontalMove * Time.fixedDeltaTime, crouch, jump);
jump = false;
//FindObjectOfType<GameManager>().EndGame();
}
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.tag == "Enemy")
{
//Destroy(FindObjectOfType<CharacterController2D>().gameObject);
GameObject.Find("Player").SetActive(false);
LevelControl.instance.GetGameOverScreen().SetActive(true);
}
}
}

If your wondering what I'm trying to do, well, when the 2 colliders of the Player and Enemy collide, I want a restart button to pop up, and the Character to get destroyed, and after that restart the level as is.
You didn't provide much but I try to work with what we have.
In LevelController you have
private void Awake()
{
if (instance == null)
{
DontDestroyOnLoad(gameObject);
instance = GetComponent<LevelControl>();
}
}
First of all just use
instance = this;
;)
Then you are doing
LevelControl.instance.GetGameOverScreenn().SetActive(true);
I don't see your setup but probably GetGameOverScreenn might not exist anymore after the Scene reload while the instance still does due to the DontDestroyOnLoad.
Actually, why even use a Singleton here? If you reload the entire scene anyway you could just setup the references once via the Inspector and wouldn't have to worry about them later after scene changes...
Also
GameObject.Find("Player").SetActive(false);
seems odd .. isn't your PlayerController attached to the Player object anyway? You could just use
gameObject.SetActive(false);
Ok, Normally it would be easier just to do this:
if (collision.gameObject.tag == "Enemy")
{
//Destroy(FindObjectOfType<CharacterController2D>().gameObject);
gameObject.SetActive(false);
LevelControl.instance.GetGameOverScreen().SetActive(true);
But this will NOT work if you want to attach the script to any other gameobjects for any reason. If you are then first make a game object variable containing the player, like this:
public GameObject Player = GameObject.Find("Player");
Then say
Player.SetActive(false);
This creates a player gameobject which you can access by calling the variable.
I found a good re-spawner for my game and I respawn 50 spheres. I want them to disappear when I walk into them but they do nothing.
Here is my script:
using UnityEngine;
using System.Collections;
public class BoxDestroy : MonoBehaviour
{
void OntriggerEnter(Collider collider)
{
if (collider.gameObject.tag == "Player")
{
Destroy(gameObject);
}
}
}
Here is my re-spawner:
using UnityEngine;
using System.Collections;
public class spawner : MonoBehaviour
{
public GameObject objectToSpawn;
public int numberOfEnemies;
private float spawnRadius = 5;
private Vector3 spawnPosition;
// Use this for initialization
void Start ()
{
SpawnObject ();
}
void Update ()
{
}
void SpawnObject()
{
for (int i= 0; i < numberOfEnemies; i++)
{
spawnPosition = transform.position + Random.insideUnitSphere * spawnRadius;
Instantiate(objectToSpawn, spawnPosition, Quaternion.identity);
}
}
}
Any ideas?
OntriggerEnter should be OnTriggerEnter! Case sensitive :)
Did you actually tag your player-gameobject with a "player" tag?
Did you mark the colliders as triggers? OnTriggerEnter vs OnCollisionEnter
Do you have a rigidbody component on your player object?
I'm trying to add a coin to my game. If the coin isn't touched then the level won't be able to switch until the player touches the coin. My scripts are trying to set a value in a variable then when the value increases to 1 then it allowed the level to change.
How do I fix my scripts?
Coin script:
using UnityEngine;
using System.Collections;
public class Coin : MonoBehaviour {
public GameObject destroyCoin;
public static int coinWorth = 0;
void OnCollisionEnter(Collision other)
{
if (other.transform.tag == "Coin")
{
Destroy(destroyCoin);
coinWorth = 1;
}
}
}
GameManager script:
using UnityEngine;
using System.Collections;
public class GameManager4 : MonoBehaviour {
Coin coinValue = GetComponent<Coin>().coinWorth;
void Update ()
{
coinValue = Coin.coinWorth;
}
void OnCollisionEnter(Collision other){
if (other.transform.tag == "Complete" && coinValue > 0) {
Application.LoadLevel(1);
}
}
}
It might be simpler to have the Coin send its value directly to the GameManager upon collision.
Should your coin perhaps be searching for a 'Player' tag rather than a 'Coin' tag (I am assuming that the Coin.cs script will be attached to a coin object which will have the 'Coin' tag).
So in you scripts it would look like this:
using UnityEngine;
using System.Collections;
public class Coin : MonoBehaviour {
// Drag your Game Manager object into this slot in the inspector
public GameObject GameManager;
public static int coinWorth = 1;
void OnCollisionEnter(Collision other)
{
// If the coin is collided into by an object tagged 'player'
if (other.transform.tag == "Player")
{
// retrieve the gamemanager component from the game manager object and increment its value
GameManager.GetComponent<GameManager4>().coinValue++;
// Destroy this instance of the coin
Destroy(gameObject);
}
}
}
Then your second script
using UnityEngine;
using System.Collections;
public class GameManager4 : MonoBehaviour {
// Declare the coinValue as a public int so that it can be accessed from the coin script directly
public int coinValue = 0;
void Update ()
{
// This shouldn't be necessary to check on each update cycle
//coinValue = Coin.coinWorth;
}
void OnCollisionEnter(Collision other){
if (other.transform.tag == "Complete" && coinValue > 0) {
Application.LoadLevel(1);
}
}
}
Of course if you are instancing the coin from a prefab then you would need to do this differently as you wouldn't be able to drag the game menager in the inspector. If thats the case then it might be worthwhile to use a singleton class for the game manager. Let me know if that is the case and I'll show you how to do this :)
I have a camera shake C# script that I want to run once the player triggers a box collider?
The camera shake code:
using UnityEngine;
using System.Collections;
public class CameraShake : MonoBehaviour
{
public Transform camTransform;
public float shake = 0f;
public float shakeAmount = 0.7f;
Vector3 originalPos;
void Awake()
{
if (camTransform == null)
{
camTransform = GetComponent(typeof(Transform)) as Transform;
}
}
void OnEnable()
{
originalPos = camTransform.localPosition;
}
void Update()
}
That's because you did not add the OnTriggerEnter, OnTriggerStay or OnTriggerExit ( depending of what you want to achieve ) function to the script.
For e.g:
void OnTriggerEnter(Collider other){
if(other.tag == "Player"){
// shake the camera here..
}
}
Don't forget to check the trigger box in the box collider.
