How to generate ground in unity2d endless runner

I currently write a game, and I have 2 scripts that generate the ground in the game. However, instead of generating them as the player comes to the end of one ground, they're generated as soon as the game starts. I don't want this to happen.
Does someone know why it happens?
Please help me fix this.
Thanks!
This is my code:
Script 1:
public class ObjectPooler : MonoBehaviour
{
public GameObject pooledObject;
public int pooledamnt;
List<GameObject> pooledObjects;
// Start is called before the first frame update
void Start()
{
pooledObjects = new List<GameObject>();
for (int i = 0; i < pooledamnt; i++)
{
GameObject obj = (GameObject)Instantiate(pooledObject);
obj.SetActive(false);
pooledObjects.Add(obj);
}
}
public GameObject GetPooledObject()
{
for (int i = 0; i < pooledObjects.Count; i++)
{
if (pooledObjects[i].activeInHierarchy)
{
return pooledObjects[i];
}
}
GameObject obj = (GameObject)Instantiate(pooledObject);
obj.SetActive(false);
pooledObjects.Add(obj);
return obj;
}
// Update is called once per frame
void Update()
{
}
}
Script 2:
public class
GroundGenerator : MonoBehaviour
{
public GameObject thePlatform;
public Transform GenOnPoint;
public float DistanceBetween;
private float PlatformWidth;
public float DistanceBewtweenmin;
public float Di stanceBetweenmax;
public ObjectPooler objectpool;
public GameObject[] thePlatforms;
private int platformSelecter;
// Start is called before the first frame update
void Start()
{
}
// Update is called once per frame
void Update()
{
GameObject newPlatform = objectpool.GetPooledObject();
newPlatform.transform.position = transform.position;
newPlatform.transform.rotation = transform.rotation;
newPlatform.SetActive(true);
}
}

Here is a basic script to generate ground as the player moves :
using UnityEngine;
public class GroundGeneration : MonoBehaviour
{
public float ClosestDistacnceFromPlayer;
public GameObject GroundTile;
public float TileWidth;
public Transform Player;
void Start()
{
//Spawn a tile so that the player won't fall off at the start
SpawnTile(1);
}
void SpawnTile(int n)
{
int i = 0;
//Spawn n tiles
while (i < n)
{
Instantiate(GroundTile, transform.position, Quaternion.identity);
i++;
//Teleport the "Ground generator" to the end of the tile spawned
transform.position += TileWidth * Vector3.right; // Or use Vector3.forward if you want to generate ground on z axis.
}
}
void FixedUpdate()
{
if (Vector3.Distance(Player.position, transform.position) <= ClosestDistacnceFromPlayer)
{
SpawnTile(1);
}
}
}
The GroundTile should have its origin at the point where it meets with the previous tile and it should be a prefab.
The Ground will start generating at the position of the object containing the ground generation script.

Unity how to "power bounce" one object from another relative to it's angle?

I'm working on a simple 3D game where some balls (fixed Z position) fall along a path (using gravity and physics material) to a small flat platform and "power bounce" off this platform. The player can rotate this platform so I want to recreate a realistic bounce direction according to the platform's angle.
I'm new to coding but so far I've figured the relationship between the vector of the ball as it comes into collision with the platform and the platform's normal, which should be a perpendicular line from the surface and that can be used to reflect the ball's vector to the other direction.
I already used OnCollisionEnter and if statement to detect whether it's the platform you are colliding with, but I don't understand where to indicate the normal of the surface and how to access it. Should it be as a public class in the other object or can it be detected from the ball game object?
I tried some examples from this and other websites and got this far:
public class OnCollision : MonoBehaviour
{
public float speed = 25f;
public Rigidbody rb;
private Rigidbody rigid;
private void Start()
{
rigid = transform.GetComponent<Rigidbody>();
}
private void OnCollisionEnter(Collision collision)
{
if (collision.transform.tag == "BouncePad") {
rb.velocity = transform.up * speed;
}
}
}
Now it bounces off vertically, so I'm guessing I should change the code where the transform.up * speed part is.
Could anyone guide me, please?
Much appreciated.

If you are already using Physics material, look into the Bounciness property. A value of 0 means no bounce, a value of 1 will lead to no loss of energy. The angle of the bounce will be calculated for you. Make sure you drag the physics material onto each object-- both the ball and the wall's material will have an effect.

Finally somebody gave me a hand and came to this solution:
public class Bounce : MonoBehaviour
{
public Rigidbody rb;
public float str = 0.21f;
public float str2 = 0.15f;
// Start is called before the first frame update
private void Start()
{
rb = GetComponent<Rigidbody>();
}
private void OnCollisionEnter(Collision col)
{
if (col.gameObject.tag == "BouncePad")
{
rb.AddForce(rb.velocity * str, ForceMode.Impulse);
}
if (col.gameObject.tag == "BouncePad2")
{
rb.AddForce(rb.velocity * str2, ForceMode.Impulse);
}
}
// Update is called once per frame
void Update()
{
}
}

public class BouncTest : MonoBehaviour
{
[SerializeField] private float hight = 3;
[SerializeField] private int times = 5;
[SerializeField] private float speed = 8;
private Vector3 _startPos;
private bool _checkUP;
private int _countTimes;
private float _hightbuf;
[HideInInspector]
public bool _bounceEnd;
private void Awake()
{
_startPos = transform.position;
}
public void TurnOnBounceEffect()
{
_bounceEnd = true;
_checkUP = false;
_hightbuf = hight;
_countTimes = 0;
}
private void FixedUpdate()
{
BounceEffect();
}
private void BounceEffect()
{
if (_bounceEnd)
{
if (!_checkUP)
{
if (transform.position.y <= (_startPos.y + _hightbuf))
transform.position = Vector2.MoveTowards(transform.position, new Vector2(_startPos.x, transform.position.y) + (Vector2.up * _hightbuf), speed * Time.fixedDeltaTime);
else
{
_checkUP = true;
}
}
else if (times != _countTimes)
{
if (transform.position.y > _startPos.y)
transform.position = Vector2.MoveTowards(transform.position, _startPos, speed * Time.fixedDeltaTime);
else
{
_countTimes++;
_checkUP = false;
_hightbuf /= 2;
}
}
else
{
transform.position = Vector2.MoveTowards(transform.position, _startPos, speed * Time.fixedDeltaTime);
if (transform.position.y <= _startPos.y)
{
_bounceEnd = false;
}
}
}
}
}

Unity How to remove gameobject if they are on same line?

I am making a game like 2 cars. And I have written code to create a instantiater. It is a car game and there are 4 lanes. Let me show you a picture of my game and yeah this is solely for practise.
Player should avoid square objects and eat circle objects but sometimes 2 square objects get spawned in a same lane making impossible for player to win. I have written this script to control that but I failed. Please help me. At least have a check to my DetectSameLaneFunction(). And tell me what I am doing wrong.

Unity3D - enemy not taking damage

In Unity3D my enemy is not taking damage upon colliding with my projectile explosion.
Although this is not the case as it the health variable is unaffected upon colliding with my projectile explosion.
My Enemy and Barrel classes inherit from Entity which handles the taking of damage (subtracting the damage variable from the health variable). Although only the barrel class is working as intended.
The tags are 100% correct and I would prefer to continue using inheritance so please no suggestions to change the method in which my classes take damage.
the class that Enemy and Barrel inherit from
using UnityEngine;
using System.Collections;
public class Entity : MonoBehaviour {
public float health = 25;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
public virtual void takeDamage(float dmg){
health -= dmg;
if (health <= 0){
Destroy(this.gameObject);
}
}
}
Enemy class
using UnityEngine;
using System.Collections;
public class Enemy : Entity {
private NavMeshAgent agent;
public GameObject target;
// Use this for initialization
void Start () {
agent = GetComponent<NavMeshAgent> ();
}
// Update is called once per frame
void Update () {
agent.SetDestination (target.transform.position);
}
}
Barrel class
using UnityEngine;
using System.Collections;
public class Barrel : Entity {
private Transform myTransform;
//Effects
public GameObject barrelExplosion;
public GameObject explosionDamage;
public GameObject explosionSound;
// Use this for initialization
void Start () {
myTransform = this.transform;
}
// Update is called once per frame
void Update () {
}
public override void takeDamage(float dmg){
health -= dmg;
if (health <= 0){
Instantiate(barrelExplosion, myTransform.position, myTransform.rotation);
Instantiate(explosionSound, myTransform.position, myTransform.rotation);
Instantiate(explosionDamage, myTransform.position, myTransform.rotation);
Destroy(this.gameObject);
}
}
}
ExplosionAOE the class that sends the damage
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
public class ExplosionAOE : MonoBehaviour {
public float damage = 100.0f;
public float lifeTime = 0.05f;
private float lifeTimeDuration;
public List<GameObject> damageTargets = new List<GameObject>();
public float radius = 15.0f;
GameManager gameManager;
void Start() {
gameManager = GameObject.FindGameObjectWithTag("GameManager").GetComponent<GameManager>();
//Destroy (this.gameObject, lifeTime);
lifeTimeDuration = Time.time + lifeTime;
transform.GetComponent<SphereCollider>().radius = radius;
}
void Update() {
//Explosion finishes, damage targets and remove AOE field
if (Time.time > lifeTimeDuration) {
foreach (GameObject target in damageTargets) {
if (target != null) {
//Calculate damage based on proximity to centre of explosion
float thisDamage = ((radius - Vector3.Distance(target.transform.position, transform.position)) / radius) * damage;
print(thisDamage);
target.GetComponent<Entity>().takeDamage(thisDamage);
//target.SendMessage("takeDamage", damage); //<< This is not good code. Let's fix this!
}
}
Destroy(this.gameObject);
}
}
void OnTriggerEnter(Collider otherObject) {
if (otherObject.gameObject.tag == "Enemy") {
damageTargets.Add(otherObject.gameObject);
}
if (otherObject.gameObject.tag == "Player") {
Vector3 jumpVector = (otherObject.transform.position - transform.position).normalized;
jumpVector *= 25;
otherObject.GetComponent<CharacterMotor>().SetVelocity(jumpVector);
}
}
}
Sorry this is a bit of a lengthy one and EVERYTHING is tagged correctly so that is not the issue, thanks.

Problem 1.
Use "Debug.Log" everywhere
void OnTriggerEnter(Collider otherObject) {
Debug.Log("in trig");
Debug.Log("otherObject.gameObject.tag is " + otherObject.gameObject.tag);
if (otherObject.gameObject.tag == "Enemy") {
Debug.Log("a");
damageTargets.Add(otherObject.gameObject);
}
if (otherObject.gameObject.tag == "Player") {
Debug.Log("b");
Vector3 jumpVector = (otherObject.transform.position -
transform.position).normalized;
jumpVector *= 25;
otherObject.GetComponent<CharacterMotor>().SetVelocity(jumpVector);
}
}
In particular, in Entity and Enemy.
Questions such as this one are instantly answered by tracking with Debug.Log.
Problem 2.
It's a PITA getting the relationships between triggers, rigidbody, etc.
It's very likely that's a problem here.
http://docs.unity3d.com/Manual/CollidersOverview.html
Go down to the annoying "trigger action matrix" and work from there.
Problem 3.
As a rule, never use the "tags" feature in Unity. (They only added tags to help "hello world" tutorials.)
In practice you use layers everywhere and always:
(Layers are particularly essential in shooting games: every single category needs a layer.)
Problem 4.
The code shown is definitely looking good. Here's some example code not unlike yours for tips.
Trivial example, note the breakaway code (the returns) inside the OnTrigger, you should do that).
Also,
use extentions
everywhere and always in Unity. Quick tutorial
it's the #1 tip if you actually want to work professionally.

Is more easy if in ExplosionAOE/OnTriggerEnter function you call the takeDamage function:
scriptCall = otherObject.GetComponent(EnemyScript);
scriptCall.takeDamage(damage);

Trying to launch a projectile towards a gameobject, doesn't move!=

I'm making a 2D Tower Defense game and want my towers to launch a prefab at minions. However it currently only spawns my desired prefab, but doesn't move it.
My two scripts:
public class Attacker : MonoBehaviour {
// Public variables
public GameObject ammoPrefab;
public float reloadTime;
public float projectileSpeed;
// Private variables
private Transform target;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
}
void OnTriggerEnter(Collider co){
if (co.gameObject.tag == "Enemy" || co.gameObject.tag == "BlockTower") {
Debug.Log("Enemy tag detected");
if(this.gameObject.tag == "Enemy" && co.gameObject.tag != "Enemy"){
Debug.Log("This is an Enemy");
// Insert for Enemey to attack Block Towers.
}
if(this.gameObject.tag == "Tower" && co.gameObject.tag != "BlockTower"){
Debug.Log("This is a Tower");
Tower Tower = GetComponent<Tower>();
Tower.CalculateCombatTime(reloadTime, projectileSpeed);
Transform SendThis = co.transform;
Tower.SetTarget(SendThis);
}
}
}
}
and
public class Tower : MonoBehaviour {
private Transform target;
private float fireSpeed;
private double nextFireTime;
private GameObject bullet;
private Attacker source;
// Use this for initialization
public virtual void Start () {
source = this.GetComponent<Attacker> ();
}
// Update is called once per frame
public virtual void Update () {
if (target) {
Debug.Log("I have a target");
//if(nextFireTime <= Time.deltaTime)
FireProjectile ();
}
}
public void CalculateCombatTime(float time, float speed){
Debug.Log("Calculate Combat Speed");
nextFireTime = Time.time + (time * .5);
fireSpeed = speed;
}
public void SetTarget(Transform position){
Debug.Log("Set Target");
target = position;
}
public void FireProjectile(){
Debug.Log("Shoot Projectile");
bullet = (GameObject)Instantiate (source.ammoPrefab, transform.position, source.ammoPrefab.transform.rotation);
float speed = fireSpeed * Time.deltaTime;
bullet.transform.position = Vector3.MoveTowards (bullet.transform.position, target.position, speed);
}
}
Basicly Attacker detects the object that collides with it, then if its tag is Tower it will send the information to Tower. My debug shows that every function works, even "Debug.Log("Shoot Projectile");" shows up.
However it doesn't move towards my target so I guess "bullet.transform.position = Vector3.MoveTowards (bullet.transform.position, target.position, step);" is never being executed?

Vector3.MoveTowards only moves the object once, it's just a instant displacement when the FireProjectile is called.
You need to create some kind of projectile script with an Update() function to make it move over time.
Here is an example:
public class Projectile : MonoBehaviour
{
public Vector3 TargetPosition;
void Update()
{
transform.position = Vector3.MoveTowards(transform.position, TargetPosition, speed * Time.DeltaTime);
}
}
Then right after your bullet instantiation, set the target:
bullet.GetComponent<Projectile>().TargetPosition = target.position;
Hope it helps.

You have to update the position of the bullet. You are only moving when you create the bullet.
Try to make a list of bullets and use the update function to change the position.
