Unity Transform not updating position realtime

I am trying to create a simple scriptable object for my shoot ability. I have that aspect working, but as I try to set my Transform to my player, it does not update the shoot position. I am very new to C#, and this script isnt complete. I still need to add the functionality to destroy the created objects. Any help would be greatly appreciated. I suspect I need to add an update function but im am not certain how to do this.
using UnityEngine.InputSystem;
using UnityEngine.AI;
using UnityEngine;
namespace EO.ARPGInput
{
[CreateAssetMenu]
public class Shoot : Ability
{
public Transform projectileSpawnPoint;
public GameObject projectilePrefab;
public float bulletSpeed = 10;
public float bulletLife = 3;
public override void Activate(GameObject parent)
{
var projectile = Instantiate(projectilePrefab, projectileSpawnPoint.position, projectileSpawnPoint.rotation);
projectile.GetComponent<Rigidbody>().velocity = projectileSpawnPoint.forward * bulletSpeed;
Destroy(projectile, bulletLife);
void OnCollisionEnter(Collision collision)
{
Destroy(projectile);
}
}
}
}

I'm still new to Unity and coding also, so take my advice with a load of salt :P.
It may be best to have a transform on your character (say just past the barrel of the player's gun) that you can put as the projectileSpawnPoint. In your code the projectileSpawnPoint is never set. Your first line of code in the "Activate" method should be something like:
public override void Activate(GameObject parent)
{
projectileSpawnPoint = playerGunBarrelTransform.transform.position;
var projectile = Instantiate(projectilePrefab, projectileSpawnPoint.position, projectileSpawnPoint.rotation);
projectile.GetComponent<Rigidbody>().velocity = projectileSpawnPoint.forward * bulletSpeed;
Destroy(projectile, bulletLife);
For destroying the projectile afterward you can keep it as you have it in OnCollision. howeer, with bullets in particular, since they tend to be instantiated A LOT and then destroyed afterward it would be best to use an object pooler for them to instantiate several of them on start and then disable and enable them as needed so you can resuse them instead of making new ones every time.

you have to create a new script that derives from Monobehaviour for your projectiles. attach that script to the projectile prefab and place the OnCollisionEnter method in that script. now your projectiles should get destroyed when touching another collider. make sure that there is a rigidbody component attached to the projectile.

Unity how to check what object triggered a trigger

I am in the middle of creating a simple 3d platformer in unity and i'm trying to make it so if you are in a certain radius and you hit the "f" key the enemy will disappear. the way i'm checking to make sure the enemy is close enough to be attacked is to have trigger sphere and when its triggered and you press "f" the enemy will be removed. i'm currently trying to see what collided with the trigger but i cant figure it out. here is my current code
using UnityEngine;
public class PlayerCombat : MonoBehaviour
{
public GameObject Enemy1;
public GameObject Enemy2;
public GameObject Enemy3;
public GameObject Enemy4;
// Update is called once per frame
void OnTriggerEnter (Trigger triggerInfo)
{
if (triggerInfo.collider.tag == "Enemy" & Input.GetKey("f"))
{
if (triggerInfo.collider.name == Enemy)
{
Enemy1.SetActive(false);
}
}
}
}

The signature is and has always been OnTriggerEnter(Collider) otherwise that message method will not be recognized by Unity and not get called at all!
And then you already have the according Collider ... what else do you need?
public class PlayerCombat : MonoBehaviour
{
// There is no need to know the enemy references beforehand at all
// you will get all required references from the Collider parameter of OnTriggerEnter itself
// I personally would however expose these two settings to the Inspector to be more flexible
// this way you can adjust these two settings within Unity without having to touch your code
public string listenToTag = "Enemy";
public KeyCode listenToKey = KeyCode.F;
// The signature has to be this otherwise the message method is never invoked at all
private void OnTriggerEnter (Collider other)
{
// Rather use "CompareTag" instead of `==` since the latter will silently fail
// for typos and nonexistent tags while "CompareTag" shows an error which is good for your debugging
// And in general you want to use the logical "&&" instead of the bitwise operator "&" for bools
if (other.CompareTag(listenToTag) && Input.GetKey(listenToKey))
{
// simply set the object you collide with inactive
other.gameObject.SetActive(false);
}
}
}
Finally just make sure that all your enemy instances actually have the tag Enemy

First, I'm pretty sure OnTriggerEnter takes a Collider as its parameter, no? https://docs.unity3d.com/ScriptReference/Collider.OnTriggerEnter.html
You can get the name of the collided object like so
//Upon collision with another GameObject,
private void OnTriggerEnter(Collider other)
{
Debug.Log($"collided with {other.gameObject.name}");
//you can check for specific components too
MyComponent myComponent = other.GetComponent<MyComponent>();
if (myComponent != null) {
// do something if it has that component on it!
}
}

Make a GameObject indestructible

I am making a shooting game using Raycasts in Unity. I have a gameObject which is a cube (The ground for my game). That cube can be destroyed by using Destroy() method. How do I make it indestructible so that it doesn't get destroyed even after using the Destroy() method?
This my FPS gun script so far:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Gun : MonoBehaviour
{
public float damage = 20f;
public float range = 150f;
//public GameObject ground;
public Camera fpsCamera;
void Start()
{
//DontDestroyOnLoad(ground);
}
void Update()
{
if (Input.GetButtonDown("Fire1")) {
Shoot();
}
}
void Shoot()
{
RaycastHit hitObject;
if (Physics.Raycast(fpsCamera.transform.position, fpsCamera.transform.forward, out hitObject, range) && hitObject.transform.name != "Ground") {
Destroy(hitObject.transform.gameObject);
}
}

It sounds like you want to sort which objects are destroyed somehow. The most simple way is of course to not call the Destroy method on that object in the first place.
However since you explain in the comments you wish to shoot and destroy some objects but not all. I would in your case make a script which either checks the tag, layer or calls a method in a script on each object.
For example, you try something similar to this:
ObjectProperties : MonoBehaviour{
public boolean CanBeDestroyed = true;
}
Add that script to the objects you shoot at.
And then when your raycast hits an object, use GetComponent on the object shot to try get ObjectProperties from that object. If the object hit has a ObjectProperties that isn't null, and that ObjectProperties has CanBeDestroyed set to be true. Then you may destroy the object.

The most simple way of achieving this, is using tags. Create a tag by highlighting the object. In the Inspector open the tags tab. Then create a tag and assign it to your object. The last thing you need to do is to check in code which tag the object you hit has.
if (Physics.Raycast(fpsCamera.transform.position, fpsCamera.transform.forward, out hitObject, range) && hitObject.transform.name != "Ground") {
switch (hitObject.tag)
{
case "immortal": //Nothing happens
break;
case "veryweak": //Objects with this tag get destroyed
Destroy(hitObject.transform.gameObject);
break;
default: //Objects that do not have a tag and do not match any of the above get destroyed
Destroy(hitObject.transform.gameObject);
break;
}
}
Hope that helps.

Score Count not working on a prefab

This is semi complicated of a question but I'll do my best to explain it:
I am making this mobile game in which you have to shoot four cubes. I'm trying to make it so when the cubes are shot by a bullet, they're destroyed and a UI text says 1/4, to 4/4 whenever a cube is shot. But it's being really weird and only counts to 1/4 even when all four cubes are shot and destroyed. I put these two scripts on the bullets (I made two separate scripts to see if that would do anything, it didn't)
And to give a better idea of what I'm talking about, here's a screenshot of the game itself.
I've been using Unity for about 6 days, so I apologize for anything I say that's noob-ish.
EDIT
So I combined the two scripts onto an empty gameobject and here's the new script:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class GameManagerScript : MonoBehaviour {
public GameObject cubes;
public Text countText;
public int cubeCount;
public Transform target;
// Use this for initialization
void Start () {
}
void OnTriggerEnter(Collider other)
{
cubes = other.gameObject;
}
// Update is called once per frame
void Update () {
cubes.transform.position = Vector3.MoveTowards(transform.position, target.position, 1f * Time.deltaTime);
if (cubes.gameObject.tag == "BULLET")
{
cubeCount = cubeCount + 1;
countText.text = cubeCount + "/4";
cubes.SetActive(false);
}
}
}
ANOTHER EDIT
I tried everything, so is there a way to detect when all the children in a parent on the Hierarchy are destroyed? Instead of counting up? This can give a better idea:
So I want to be able to detect when Cube, Cube1, Cube2, and Cube3 have all been destroyed.

The answer is pretty simple: Since every individual bullet has that script, each bullet has its own score.
For something like a score you want a single spot to store it, e.g. a script on an empty gameobject that serves as game controller. Just access that in the collision and increase the score (maybe have a look on singletons here).
You can combine those two scripts and actually it might be better to not have this on the bullet, but on the target because there are probably less of them which will save you some performance. (And it does more sense from a logical point of view.)
Edit:
I assume you create the bullets using Instantiate with a prefab. A prefab (= blueprint) is not actually in the game (only objects that are in the scene/hierarchy are in the game). Every use of Instantiate will create a new instance of that prefab with it's own version of components. A singleton is a thing that can only exist once, but also and that is why I mention it here, you can access it without something like Find. It is some sort of static. And an empty gameobject is just an object without visuals. You can easily create one in unity (rightclick > create empty). They are typically used as container and scriptholders.
Edit:
What you want is:
An empty gameobject with a script which holds the score.
A script that detects the collision using OnTriggerEnter and this script will either be on the bullets or on the targets.
Now, this is just a very quick example and can be optimized, but I hope this will give you an idea.
The script for the score, to be placed on an empty gameobject:
public class ScoreManager : MonoBehaviour
{
public Text scoreText; // the text object that displays the score, populate e.g. via inspector
private int score;
public void IncrementScore()
{
score++;
scoreText.text = score.ToString();
}
}
The collision script as bullet version:
public class Bullet : MonoBehaviour
{
private ScoreManager scoreManager;
private void Start()
{
scoreManager = GameObject.FindWithTag("GameManager").GetComponent<ScoreManager>(); // give the score manager empty gameobject that tag
}
private void OnTriggerEnter(Collider other)
{
if(other.CompareTag("Target") == true)
{
// update score
scoreManager.IncrementScore();
// handle target, in this example it's just destroyed
Destroy(other.gameObject);
}
}
}

Unity3d not liking collision

using UnityEngine;
using System.Collections;
public class chicken_for : MonoBehaviour {
// Use this for initialization
void Start () {
}
// Update is called once per frame
void FixedUpdate () {
if (collision.gameObject.Quad == collisionObject){
Application.LoadLevel("SciFi Level");
}
}
}
I am attempting to when A person touches a quad, he goes to this sci-fi fortress. It however says the name 'collision' does not exist in the current context.

You're referencing a variable (collision) that doesn't exist. You've got a variable collisionObject that doesn't exist, too.
collision is typically the name of the argument to the OnCollisionEnter method. Your code should probably be inside this method instead of FixedUpdate. I'm guessing that you've copied code from a tutorial somewhere but put it in the wrong method.
collisionObject on the other hand is harder to guess, but I expect that if your script is intended to be a component on the player object, then collisionObject should be your quad; if the script is on the quad then collisionObject should be the player.
Either way, you need to declare that variable - probably as a public field so that you can populate it from the inspector.

Add a new function and make sure the player is tagged as player in the inspector. You also need to make sure that there is a collider on the quad that the player touches and a rigidbody component on the player.
using UnityEngine;
using System.Collections;
public class chicken_for : MonoBehaviour {
//This function will handle the collision on your object
void OnCollisionEnter (Collider col){
if(col.gameobject.tag == "Player"){ //if colliding object if tagged player
Application.LoadLevel("SciFi Level"); //load the sci-fi level
}
}
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
}
This should get you roughly where you want to be!
