I'm trying to set a game object active in my Unity 3D project (with Oculus SDK).
Hopefully this would be set active when the player collides with triggerCube (specifically want to be able to pick up triggerCube and then ViewSight gameobject is set active.
When player lets go, ViewSight gameobject is set to false.
I've tried turning off ViewSight gameobject in the inspector but still having it in the hierarchy. It didn't work so I made a prefab of it and deleted it from the hierarchy (and pulled it in to the script in the inspector for the triggerCube) and it didn't work that way either. Not sure what I'm doing wrong.
Thanks for your help.
This is the script I have and its attached to the triggerCube:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class ViewFinderStateTrigger : MonoBehaviour
{
public GameObject ViewSight;
public void OnTriggerEnter(Collider col)
{
if (col.gameObject.name == "triggerCube")
{
ViewSight.SetActive(true);
Debug.Log("Active");
}
else
{
ViewSight.SetActive(false);
Debug.Log("Not Active");
}
}
}

In my scene, there are multiple objects with the same layer and tag. I have a variable that will be set to the gameobject for one of these objects. I would like to do something when I collide with the object that is set to the variable.
My current code is:
private void OnCollisionEnter2D(Collision2D collision)
{
if (collision.otherCollider == targetFood)
{
Debug.Log("I am touching food");
}
}
I've tried a few different methods of checking if it is touching the food, but none have worked. Help would be appreciated!
If you get the game object from the collision, you should be able to determine if the target food has been touched.
using UnityEngine;
public class Example : MonoBehaviour
{
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject == targetFood)
{
Debug.Log("I am touching food");
}
}
}
This is assuming that targetFood is a variable that is of type GameObject.
I try to create a shop system where you can buy a character to play with. When I buy a character in the Shop Scene, the bool value in the Inventory script is set to true. When I switch to the Level1 Scene, my character is not spawned. I suppose there is a bug in my GameManager script but I can not find it. Can you please help me? I do not know any more.
GameManager script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameManager : MonoBehaviour
{
public GameObject Joli;
public GameObject Ninn;
public GameObject Spaci;
public GameObject Woodie;
public GameObject Plumbt;
public GameObject canvasObject;
public Inventory myInventory;
// Start is called before the first frame update
void Start()
{
myInventory = GameObject.FindObjectOfType<Inventory>();
if (myInventory.GetNinn() == true)
{
GameObject Ninnnew = Instantiate(Ninn, Ninn.transform.position, Quaternion.identity) as GameObject;
Ninnnew.transform.SetParent(canvasObject.transform, false);
}
if (myInventory.GetSpaci() == true)
{
GameObject Spacinew = Instantiate(Spaci, Spaci.transform.position, Quaternion.identity) as GameObject;
Spacinew.transform.SetParent(canvasObject.transform, false);
}
}
}
There is currently not enough information / code in your question, but when you change scene, your objects are destroyed by default, and new ones are isntantiated, effectively resetting any values that are set in them.
You need to prevent your Inventory or any object holding data you need to keep that it should not be destroyed when switching scenes, by using DontDestroyOnLoad for instance :
https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html
I'm making some sort of a Evolution simualtor game. I have a script that is supposed to destroy the GameObject it's attached to when a creature's CapsuleCollider Triggers the OnTriggerEnter().
I have a problem that even tho the Creature's collider isn't even close to the Food, it still destroys the GameObject.
My script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class FoodEat : MonoBehaviour
{
public GameObject FoodGO;
public Rigidbody FoodRB;
private void OnTriggerEnter(Collider Creature)
{
Destroy(FoodGO);
}
void Start()
{
FoodRB = GetComponent<Rigidbody>();
FoodGO = FoodRB.gameObject;
}
void Update()
{
Rigidbody[] allRigidBodies = (Rigidbody[])FindObjectsOfType(typeof(Rigidbody));
foreach (Rigidbody body in allRigidBodies)
{
if (body.gameObject.layer == 10)
{
OnTriggerEnter(body.gameObject.GetComponent<CapsuleCollider>());
}
}
}
}
OnTriggerEnter is a monobehaviour lifecycle method. You should not call it from your own code; it will automatically be called when it detects collisions.
Furthermore, the logic in your code right now seems to be incorrect, it is...
"Every frame, loop through all rigidbodies in the scene and if 1 is found on layer 10, destroy the FoodGO"
Simply remove your entire Update method and put an if in your Collision method, and it should work:
[RequireComponent(typeof(Rigidbody), typeof(Collider))]
public class FoodEat : MonoBehaviour
{
private void OnTriggerEnter(collider other)
{
Debug.Log(other.gameObject.name + " on layer " + other.gameObject.layer);
if (other.gameObject.layer == 10)
Destroy(this.gameObject);
}
}
A few noteworthy edits of your code:
I removed FoodGO, since it's the GameObject this script is attached to, you can access it by just writing gameObject or this.gameObject.
I remove the Rigidbody reference since it is not used anymore, and thus the entire Start() method.
Since this code requires a Rigidbody and a Collider to work, I added a [RequireComponent] attribute in the top, which will make Unity tell you if you forgot to add those components on the object you attach this script to.
I added a Debug.Log that prints the name & the layer on the creature that collides with the food, so you can debug and make sure it is working as expected
I am just trying to activate game over screen when the Player's activate is 'false'. There is no animation, just the
There are 3 objects that need to be active and i added the script to those 3 objects but the screen does not appear.
How can i fix?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameOverManager : MonoBehaviour
{
public GameObject _player;
void Start()
{
_player = GameObject.FindGameObjectWithTag("Player");
}
void Update()
{
if (_player.activeInHierarchy == false)
{
gameObject.SetActive(true);
}
else
{
gameObject.SetActive(false);
}
}
}
My suspicion is the following. Whenever a Gameobject is not enabled, its code does not run. Test this by adding a Debug.Log("test") message.
If no message appears you can be certain that this check is never evaluated. To work around this simply add a script that is bound to an active gameObject. Creat a new empty gameobject in the scene. And add something like this:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameOverManager : MonoBehaviour
{
public GameObject _player;
public GameObject _endscreen;
void Update()
{
if (_player.activeInHierarchy == false)
{
_endscreen.SetActive(true);
}
else
{
_endscreen.SetActive(false);
}
}
}
Assign the Variables in the Inspector by dragging the object to the empty fields. Never use GameObject.Find Methods.
If you need any further help tell me :)
What you're currently doing is to find a single GameObject and checking whether that is active or not.
It would make more sense, and be more optimized, if each player object adds himself to a list of all players when he spawns. You can then loop over that list instead to check all players.
An even better way would be if you only call that "GameOver" check after a player has died. So when you call whichever method kills him.
Based on Franz Answer, I did some modification in the code. You won't need any if else statement if you use a shortcut.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class GameOverManager : MonoBehaviour
{
public GameObject _player;
public GameObject _endscreen;
void Update()
{
_endscreen.SetActive(!_player.activeInHierarchy);
}
}
I'm going through the worse struggle right now. I'm trying to create a game with pitfalls that if the players fall through, they respawn and the game counts their death. I'm completely at wit's end and don't know where to even start with this. The game is 3D
using UnityEngine;
using System.Collections;
public class Respawn : MonoBehaviour {
public Transform spawnPoint;
public float minHeightForDeath;
public GameObject player;
void Start () {
}
// Update is called once per frame
void Update () {
if (player.transform.position.y < minHeightForDeath) {
player.transform.position = spawnPoint;
}
}
}
Use a collider on a plane/cube/whatever works for you, and set it to be a trigger. So when they pass through the trigger collider, it can record them and do what you want with it.
Use the OnTriggerEnter method script
void OnTriggerEnter(Collider other)
{
other.transform.position = spawnPoint.position;
}
You are not putting any data in the "minHeightForDeath" float. Unless you do it in the editor.
Other than that, have you put the script on the player gameObject? And have you set what you have to in the editor?
