Enemy Projectile Script Won't Shoot Closest Object

Enemy Projectile Script Won't Shoot Closest Object - c#

I Have been trying to figure out how the Enemy doesn't return multiple GameObjects it only returns one.Im not sure whether it is my Bullet script that it allows only one object to return. I'm currently trying to develop a Game with multiple players like Slither.io so I'm not sure if the performance is affected I would like to use (List Function) but dont know where to start and I'm using a later version Unity 2017.3.1f1. Much Appreciated for your help.The scripts are below.
public class RandomAIProjectile
{
private GameObject[] target;
public float speed;
Rigidbody2D bulletRB;
public GameObject explosionEffect;
// Find Targets Section.
void Start ()
{
if (target == null)
target = GameObject.FindGameObjectsWithTag("Player");
for (int i = 0; i < target.Length; i++)
{
bulletRB = GetComponent<Rigidbody2D> ();
Vector2 moveDir = (target[i].transform.position - transform.position).normalized * speed;
bulletRB.velocity = new Vector2 (moveDir.x, moveDir.y);
Destroy (this.gameObject, 2);
}
}
private void OnTriggerEnter2D(Collider2D other)
{
// Decoy Script To Destroy Players.
if (other.gameObject.GetComponent<BlackthronpodDiePlayer>() != null)
{
Destroy (other.gameObject);
Destroy (gameObject);
}
// Damage Effect.
if (other.gameObject.tag == "Player") {
Instantiate (explosionEffect, transform.position, Quaternion.identity);
Destroy(gameObject);
}
// Player (Bullet) Destroy Enemy.
if (other.CompareTag ("Bullet"))
{
Destroy (other.gameObject);
Destroy (gameObject);
}
}
}

if (collision.CompareTag ("Player"))
{
playerX.health --;
Debug.Log(playerX.health);
Destroy(gameObject);
}
// Player Score Manager.
if (collision.tag == "Bullet")
{
Game.AddToScore(1);
Destroy(gameObject);
}
}
}

Make sure that you have Rigidbody2d attached on your enemy and player. And also, is there any error coming in the code?

How to make Enemy FLIP and ATTACK in Unity2D?

I was following a tutorial for creating an enemy in Unity, but they didn't teach how to flip the enemy in case the Player goes to the other side of the map, oppose to where the enemy is.
So I tried to increase the raycast area, so when the Player collides with it from behind, the enemy will know that it has to flip. But something isn't working, cause it goes fine to the Player when it's facing the left side of the map, but once it flips, it totally stops working, and I can't figure it out why.
Anyone have any idea what should I do?
Here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Skeleton : MonoBehaviour
{
#region Public Variables
public Transform rayCast;
public LayerMask raycastMask;
public GameObject target;
public float rayCastLength;
public float attackDistance; //Mininum distance to attack
public float moveSpeed;
public float timer; // Cooldown b/w attacks
public bool inRange; //check if the player is near
#endregion
#region Private Variables
private RaycastHit2D hit;
private Animator anim;
private float distance; //Distance b/w enemy and player
public bool attackMode;
private float intTimer;
#endregion
void Awake() {
intTimer = timer;
anim = GetComponent<Animator>();
}
void Update() {
if (inRange)
{
hit = Physics2D.Raycast(rayCast.position, Vector2.left, rayCastLength, raycastMask);
}
//When the player is detected
if(hit.collider != null)
{
EnemyLogic();
}
// If it's not inside the raycast
else if(hit.collider == null)
{
inRange = false;
}
// If the player leaves the range
if (inRange == false)
{
anim.SetBool("canWalk", false);
StopAttack();
anim.SetInteger("Idle", 0);
}
}
void OnTriggerEnter2D(Collider2D col)
{
if(col.gameObject.tag == "Player")
{
target = col.gameObject;
inRange = true;
Flip();
}
}
void EnemyLogic()
{
distance = Vector2.Distance(transform.position, target.transform.position);
if(distance > attackDistance)
{
Move();
StopAttack();
}
else if(attackDistance >= distance)
{
Attack();
}
}
void Move()
{
anim.SetInteger("Idle", 1);
anim.SetBool("canWalk", true);
if (!anim.GetCurrentAnimatorStateInfo(0).IsName("attack"))
{
Vector2 targetPosition = new Vector2(target.transform.position.x, transform.position.y);
transform.position = Vector2.MoveTowards(transform.position, targetPosition, moveSpeed * Time.deltaTime);
}
}
void Attack()
{
timer = intTimer; //reset timer
attackMode = true;
anim.SetInteger("Idle", 1);
anim.SetBool("canWalk", false);
anim.SetBool("Attack", true);
}
void StopAttack()
{
attackMode = false;
anim.SetBool("Attack", false);
}
// Detects if the player is on the other side
void Flip()
{
Vector3 rotation = transform.eulerAngles;
if(target.transform.position.x < transform.position.x)
{
rotation.y = 180f;
}
else
{
rotation.y = 0f;
}
transform.eulerAngles = rotation;
}
}

You can flip the enemy using localScale. Do this:
if (Player.transform.position.x < this.transform.position.x)
{
transform.localScale = new Vector3(-1, 1, 1);
}else
{
transform.localScale = new Vector3(1, 1, 1);
}
This detects whenever the player's x position is greater or lower than the enemy and flips the whole object.

Why does OnCollisionEnter2D not working? Unity

I have an enemy prefab with and a bullet prefab with rigidbody2D and boxcolliders to both of them. I have made a TakeDamage function for the enemy when i made meelee combat and also a bullet shooting script. I made a simple OnCollisionEnter2D on the enemy(code is below) and they do collide and give the collision effect but the function doesn't work, it doesn't give any errors either... What do I do now?

}

How to make a shooting range for guns in unity2D?

I want my wepons to have a shooting range in my 2D game.For example if the bullet is out of range then destroy the bullet.Is it a problem if i don't use RayCast?
My script for the Wepon:
//Initialization
public GameObject Bullet;
public Transform FirePoint;
//WeponStats
public float BulletSpeed;
public int Damage;
public float Range;
private float TimeBtwShots;
public float StartTimeBtwShots;
private void Start()
{
}
private void Update()
{
if (TimeBtwShots <= 0)
{
if (Input.GetButton("Fire1"))
{
Shoot();
TimeBtwShots = StartTimeBtwShots;
}
}
else
{
TimeBtwShots -= Time.deltaTime;
}
}
void Shoot()
{
GameObject bullet2 = Instantiate(Bullet, FirePoint.position, FirePoint.rotation);
Rigidbody2D rb = bullet2.GetComponent<Rigidbody2D>();
rb.AddForce(FirePoint.right * BulletSpeed, ForceMode2D.Impulse);
}
And for the bullet:
public float Delay;
void Start()
{
Destroy(gameObject, Delay);
}
public void OnCollisionEnter2D(Collision2D other)
{
if (other.gameObject.CompareTag("Enemy"))
{ //take damage function, nothing important
Destroy(gameObject);
Wepon_Script script_W = GameObject.FindGameObjectWithTag("Wepon").GetComponent<Wepon_Script>(); //Wepon script
Enemy_Core script_E = GameObject.FindGameObjectWithTag("Enemy").GetComponent<Enemy_Core>(); //Enemy script
script_E.TakeDamage(script_W.Damage);
}
}
enter image description here

It seems you're already destroying the bullet after a delay:
Destroy(gameObject, Delay);
If you want the bullet to be destroyed after a distance traveled you could divide the distance by the speed.
Destroy(gameObject, Range / BulletSpeed);
If you want to measure dynamic distance traveled you could keep a track of it inside the bullet.
void FixedUpdate()
{
var distanceDelta = (transform.position - lastPos).magnitude;
distanceTravelled += distanceDelta;
lastPos = transform.position;
if (distanceTravelled > Range) Destroy(gameObject);
}

I am trying to do a score that increase on ball collision with brick

I am doing a game in Unity for a school project.
I need to increase the score when the ball collides with brick. What I am doing wrong please? Below is the code that I tried to use. Score starts at zero but never goes more than 1. Any help of how I can fix this issue please?
public class Brick : MonoBehaviour
{
public int hitPoint = 3;
public GameObject explosion;
public GameObject heart;
[Range(0f, 1f)]
public float percentage;
float randNum;
public float fallSpeed = 8.0f;
public Sprite OneHits;
public Sprite TwoHits;
public Sprite ThreeHits;
public Text ScoreText;
private int points;
GameObject ball;
void Start()
{
ball = GameObject.FindGameObjectWithTag("ball");
}
void Update()
{
ScoreText.text = "Score " + points ;
randNum = Random.Range(0f, 1f);
if (hitPoint == 1)
{
this.GetComponent<SpriteRenderer>().sprite = OneHits;
}
if (hitPoint == 2)
{
this.GetComponent<SpriteRenderer>().sprite = TwoHits;
}
if (hitPoint == 3)
{
this.GetComponent<SpriteRenderer>().sprite = ThreeHits;
}
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.tag == "ball")
{
ball = collision.gameObject;
hitPoint--;
points++;
if (hitPoint <= 0)
{
Destroy(this.gameObject);
Instantiate(explosion, transform.position, transform.rotation);
if (randNum < percentage)
{
Instantiate(heart, transform.position, transform.rotation);
}
}
}
}
}

There are a couple of things wrong with your code.
If you destroy the game object the script is running on the script will stop, so I would move your destroy command to the end of your method.
I am guessing that you dont want points to be different for each brick, I would move points to another class called scoreboard or something. For the time being I made points static. This means that only one copy of this variable exists and if one brick adds a point it gets reflected across all bricks.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Test : MonoBehaviour
{
public int hitPoint = 3;
public GameObject explosion;
public GameObject heart;
[Range(0f, 1f)]
public float percentage;
float randNum;
public float fallSpeed = 8.0f;
public Sprite OneHits;
public Sprite TwoHits;
public Sprite ThreeHits;
public Text ScoreText;
public static int points;
GameObject ball;
void Start()
{
ball = GameObject.FindGameObjectWithTag("ball");
}
void Update()
{
ScoreText.text = "Score " + points;
randNum = Random.Range(0f, 1f);
if (hitPoint == 1)
{
this.GetComponent<SpriteRenderer>().sprite = OneHits;
}
if (hitPoint == 2)
{
this.GetComponent<SpriteRenderer>().sprite = TwoHits;
}
if (hitPoint == 3)
{
this.GetComponent<SpriteRenderer>().sprite = ThreeHits;
}
}
private void OnCollisionEnter(Collision collision)
{
if (collision.gameObject.CompareTag("ball"))
{
ball = collision.gameObject;
hitPoint--;
points++;
if (hitPoint <= 0)
{
Instantiate(explosion, transform.position, transform.rotation);
if (randNum < percentage)
{
Instantiate(heart, transform.position, transform.rotation);
}
Destroy(gameObject);
}
}
}
}

How to change hit point to crosshair?

Below script uses a function whereas there first is a check if there is a object in range and if it, it is.
On pressing mouse key, the projectile is shooting towards the pivot point of that said object. I want the projectile to
always being able to fire (indifferent if the object is in range) and
shoot towards the crosshair (to the screen midpoint) and NOT towards the object pivot point.
I am a novice at coding and I can't see what code to remove and what to add.

This is the code attached to the projectile

Destroy(gameObject);
}
}
public void SetTarget(GameObject target)
{
this.Target = target.transform;
}
public void SetTarget(ShootHit hit) => SetTarget(hit.gameObject);
}
This script is how and where the Projectile Spawns. It is attached to an empty gameobject located on the muzzle of the gun.
public class ProjectileSpawner : MonoBehaviour
{
public GameObject projectileInsert;
public GameObject projectileExtract;
public float projectileSpeed = 1.0f;
GameObject projectile;
public void Insert(GameObject target)
{
if (projectile) return;
projectile = Instantiate(projectileInsert, transform.position, Quaternion.identity);
ProjectileScript projectileScript = projectile.GetComponent<ProjectileScript>();
projectileScript.SetTarget(target);
projectileScript.speed = projectileSpeed;
// Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
// projectileSpawn.parent.GetComponent<Collider>());
}
public void Extract(GameObject target)
{
if (projectile) return;
projectile = Instantiate(projectileExtract, target.transform.position, Quaternion.identity);
ProjectileScript projectileScript = projectile.GetComponent<ProjectileScript>();
projectileScript.SetTarget(gameObject);
projectileScript.speed = projectileSpeed;
// Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
// projectileSpawn.parent.GetComponent<Collider>());
}
}

In the ProjectileSpawner, add a LayerMask field to filter out invalid collisions (set it in the inspector) for the non-homing projectile. You'll set this in the inspector to make the non-homing projectiles collide with the desired layers:
public LayerMask collisionLayers;
In Insert, find the ray going from the screen's center, and use it and the LayerMask as a parameter to SetTarget:
public void Insert(GameObject target)
{
if (projectile) return;
Ray centerRay = Camera.main.ScreenPointToRay(new Vector3(Screen.width/2, Screen.height/2, 0f));
projectile = Instantiate(projectileInsert, transform.position, Quaternion.identity);
ProjectileScript projectileScript = projectile.GetComponent<ProjectileScript>();
projectileScript.SetTarget(centerRay, collisionLayers);
projectileScript.speed = projectileSpeed;
// Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
// projectileSpawn.parent.GetComponent<Collider>());
}
public void Extract(GameObject target)
{
if (projectile) return;
projectile = Instantiate(projectileExtract, target.transform.position, Quaternion.identity);
ProjectileScript projectileScript = projectile.GetComponent<ProjectileScript>();
projectileScript.SetTarget(gameObject);
projectileScript.speed = projectileSpeed;
// Physics.IgnoreCollision(projectile.GetComponent<Collider>(),
// projectileSpawn.parent.GetComponent<Collider>());
}
Then in the ProjectileScript, add a bool field to remember if the projectile homes on a gameObject or if it follows a ray, a Ray field to remember such a ray, and a LayerMask field to remember what to collide with:
public bool isHoming;
public Ray TargetRay
public LayerMask collisionLayers;
Then, in public void SetTarget(GameObject target), set that bool to true:
public void SetTarget(GameObject target)
{
this.Target = target.transform;
isHoming = true;
}
And make a new public void SetTarget(Ray shootRay) that remembers a Ray and LayerMask and sets the bool to false:
public void SetTarget(Ray shootRay, LayerMask collisionLayers)
{
this.TargetRay = shootRay;
this.collisionLayers = collisionLayers;
isHoming = false;
}
Also, in ProjectileScript, you will need to change the FixedUpdate method to check if the bool is true, and if it is, then do the same as before. Otherwise, move along the ray and destroy it if it travels too far:
public float maxDistanceBeforeDestroy = 100f;
...
void FixedUpdate()
{
if (isHoming)
{
// _rigidbody.AddForce((Target.position - transform.position).normalized, ForceMode.Impulse);
Collider targetCollider = Target.GetComponent<Collider>();
Vector3 targetDirection;
if (targetCollider)
targetDirection = targetCollider.ClosestPoint(transform.position) - transform.position;
else
targetDirection = Target.position - transform.position;
_rigidbody.velocity = targetDirection.normalized * speed;
if (Vector3.Distance(transform.position, Target.position) < 1.0f)
{
//make the explosion
GameObject ThisExplosion = Instantiate(Explosion, gameObject.transform.position, gameObject.transform.rotation) as GameObject;
//destory the projectile
Destroy(gameObject);
}
}
else
{
_rigidbody.velocity = TargetRay.direction.normalized * speed;
// Check if it has traveled too far
if ((transform.position - TargetRay.origin).magnitude > maxDistanceBeforeDestroy )
{
Destroy(gameObject);
}
}
}
Then, add an OnCollisionEnter method that doesn't do anything if the projectile is homing. But if it isn't, it checks if the collision matches the LayerMask, and if it does, it makes the explosion and destroys the projectile:
void OnCollisionEnter(Collision other)
{
if (isHoming)
{
return;
}
if( && ((1<<other.gameObject.layer) & collisionLayers) != 0)
{
//make the explosion
GameObject ThisExplosion = Instantiate(Explosion,
gameObject.transform.position,
gameObject.transform.rotation) as GameObject;
//destroy the projectile
Destroy(gameObject);
}
}

Your question is a bit vague and doesn't look like you have put a lot of effort into understanding the code and trying to alterate it. Anyway I'll do my best.
always being able to fire (indifferent if the object is in range)`
probably simply set aimAssistRadius = 0; or entirely remove the check
if (Vector3.Distance(_target.Value.gameObject.transform.position, transform.position) > aimAssistRadius)
{
_target = null;
}
shoot towards the crosshair (to the screen midpoint) and NOT towards the object pivot point.
The script you posted (probably not yours) seems to have the entire purpose of doing what you not want to do: Aim assist. Removing it probably changes a lot of things but the simpliest would be to simply set the ProjectileScript._rigidbody.velocity in the moment the projectile is instantiated. Unfortunately you didn't provide the code where this happens.
I don't see in which moment your ShootComponent interacts with the ProjectileScript but probably in one of those UnityEvents ... ?
But in general it would maybe simply look like
public class ProjectileScript : MonoBehaviour
{
public float speed = 1.0f;
private RigidBody _rigidbody;
private void Awake()
{
_rigidbody = GetComponent<RigidBody>();
}
public void SetDirection(Vector3 direction)
{
_rigidbody.velocity = direction.normalized * speed;
}
}
and whereever you Instantiate the projectile do
var projectile = instantiatedObject.GetComponent<ProjectileScript>();
var direction = Camera.main.transform.forward;
projectile.SetDirection(direction);
as you can see you will have to make the
if (Vector3.Distance(transform.position, Target.position) < 1.0f)
{
//make the explosion
GameObject ThisExplosion = Instantiate(Explosion, gameObject.transform.position, gameObject.transform.rotation) as GameObject;
//destory the projectile
Destroy(gameObject);
}
happen somewhere else since the code will not be target based anymore ... I would probably use OnCollisionEnter instead something like e.g.
private void OnCollisionEnter(Collision collision)
{
// maybe only collide with a certain tag
if(collision.gameObject.tag != "Target") return;
//make the explosion
GameObject ThisExplosion = Instantiate(Explosion, gameObject.transform.position, gameObject.transform.rotation) as GameObject;
//destory the projectile
Destroy(gameObject);
}

Make sure that you have Rigidbody2d attached on your enemy and player. And also, is there any error coming in the code?
