How to attract multiple objects to a target object? C#,
So im very new to coding and Unity. It's my 5th day on doing programming. I am a 3d artist but now I'm also trying to learn coding as an interest and hobby.
I have made a basic starting game. I have a "Player" which is just running and you have to dodge the obstacles and collect the coins.
Now like how in Subway Surfers when you get a power-up, all coins within a range get attracted towards you and are collected.
I'm trying to do the same, but I do not know how.
Here is what I have typed for the attraction of the coins:
public Transform coins;
public Transform magnet;
public float speed;
void FixedUpdate ()
{
coins.position = Vector3.MoveTowards(coins.position, magnet.position, speed * Time.deltaTime);
}
Magnet is the player .. Coins are the coins ( but the problem is, I am only able to reference just 1 coin. Whereas I have 100+ coins in the game ) because when calling public Transform coins, i can only put in 1 coin as a reference.
Help me out and tell me what to do.
How can I attract multiple coins and only when they get in a specific range, because currently the one coin which is being attracted, it starts getting attracted as soon as the game starts. I want it to only happen when it is at a specific distance from the player.
Also also ... I have tried referencing the whole GameObject (group) of the coins and it behaves total opposite, all the coins run away from the player ..

You will have to get all the coins that are around the player, and run the code you have on each of them. Below I do that using the OverlapSphere method. All your coins will need to have a collider somewhere in the prefab. magnetDistance is essentially the radius of the magnet effect.
public Transform magnet;
public float speed;
public float magnetDistance;
void Update ()
{
// Ideally you want to perhaps put coins on a specific physics layer, and use a layer mask to only check that layer (Better performance)
// Take a look at https://docs.unity3d.com/ScriptReference/Physics.OverlapSphere.html
Collider[] hitColliders = Physics.OverlapSphere(magnet.position, magnetDistance);
for (int i = 0; i < hitColliders.length; i++)
{
// do whathever you need here to determine if an object is a coin
// Here I assume that all the coins will be tagged as coin
if (hitColliders[i].tag == "coin")
{
Transform coin = hitColliders[i].transform;
coin.position = Vector3.MoveTowards(coin.position, magnet.position, speed * Time.deltaTime);
}
}
}
Use this method. Make a big sphere collider around your player, and when you collect power up. then check collision with your collectable item. and OnTriggerEnter(Collider other) { if(other.gameObject.tag=="COLLECTABLE_TAG") { other.SendMessage("CanAttract"); } }enter code here
public Transform target;
bool canAttract=false;
void Update () {
if (canAttract) {
Vector3.MoveTowards (this.transform.position, target.transform.position, 1 * Time.deltaTime);
}
}
void CanAttract()
{
canAttract = true;
}
This answer doesn't make any sense, this is like you're combining a player script, and the coin script. You're looking if a object is entering the player's spherical collision area, yet then you move the player itself towards the player itself, on the 6th line.
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class CoinsBehaviour : MonoBehaviour { private GameObject player; private float CoinSpeed = 30.0f; private Transform playerTransform;
public float CoinRotateSpeed = 5;
void Start()
{
player = GameObject.FindGameObjectWithTag("Player");
playerTransform = player.GetComponent<Transform>();
transform.position = new Vector3(transform.position.x, transform.position.y, 0f);
}
void Update()
{
if(PlayerScript.isMagnetPowerup == true)
{
CoinsPowerup();
}
}
void FixedUpdate()
{
transform.Rotate(Vector3.down * CoinRotateSpeed);
}
public void CoinsPowerup()
{
float distance = Vector3.Distance(playerTransform.position, transform.position);
// float distance = playerTransform.position.y - transform.position.y;
float maxDistance = 10.0f;
// float maxDistance = 0.030f;
if (distance < maxDistance)
{
// Debug.Log ("Now near in: "+ Vector3.Distance(playerTransform.position, transform.position));
transform.position = Vector3.MoveTowards(transform.position,playerTransform.position + new Vector3(0,-2,0), CoinSpeed * Time.deltaTime);
}
}
