Part 26 really helped me to create a better coin collect system, thank you so much! However, I would like to know, how passive bonuses like “greed” from “PlayerStats.cs” are added to the “PlayerCollector.cs”. How can this be archieved? Thank you again and Cheers!

EDIT: I found a solution! I also added some sound for Gold Pickup ;-)

using System.Collections;
using System.Collections.Generic;
using UnityEditor.U2D.Animation;
using UnityEngine;

[RequireComponent(typeof(CircleCollider2D))]
public class PlayerCollector : MonoBehaviour
{
    PlayerStats player;
    CircleCollider2D detector;
    public float pullSpeed;

    public UICoinDisplay UI;
    float coins;

    [Header("Audio Source")]
    public AudioSource collectableSound;

    [Header("Collect Gold Audio")]
    public AudioClip coinCollect;
    public float coinCollectVolume = 0.4F;

    [Header("Remove Gold Audio")]
    public AudioClip coinRemove;
    public float coinRemoveVolume = 0.4F;

    private void Start()
    {
        player = GetComponentInParent<PlayerStats>();
    }


    public void SetRadius(float r)
    {
        if (!detector) detector = GetComponent<CircleCollider2D>();
        detector.radius = r;
    }

    public float GetCoins() { return coins; }
    //Updates coins Display and information
    public float AddCoins(float amount)
    {
        var greed = player.Stats.greed;

        if (greed > 0)
        { 
        coins += amount * (int)greed; 
        collectableSound.PlayOneShot(coinCollect, coinCollectVolume);
        if (UI) UI.UpdateDisplay();
        return coins;
        }
        else {
        coins += amount;
        collectableSound.PlayOneShot(coinCollect, coinCollectVolume);
        if (UI) UI.UpdateDisplay();
        return coins;
        }
    }

    public float RemoveCoins(float amount)
    {
        coins -= amount;
        collectableSound.PlayOneShot(coinRemove, coinRemoveVolume);
        if (UI) UI.UpdateDisplay();
        return coins;
    }

    // Saves the collected coins to the save file.
    public void SaveCoinsToStash()
    {
        SaveManager.LastLoadedGameData.coins += coins;
        coins = 0;
        SaveManager.Save();
    }

    void OnTriggerEnter2D(Collider2D col)
    {
        //Check if the other GameObject is a Pickup.
        if (col.TryGetComponent(out Pickup p))
        {
            p.Collect(player, pullSpeed);
        }

        if (col.TryGetComponent(out PickupResource pr))
        {
            pr.Collect(player, pullSpeed);
        }
    }

}

Based on the user’s code, the passive bonus “greed” from PlayerStats.cs is added to PlayerCollector.cs in the AddCoins() method:

public float AddCoins(float amount)
{
    var greed = player.Stats.greed;

    if (greed > 0)
    { 
        coins += amount * (int)greed; 
        collectableSound.PlayOneShot(coinCollect, coinCollectVolume);
        if (UI) UI.UpdateDisplay();
        return coins;
    }
    else {
        coins += amount;
        collectableSound.PlayOneShot(coinCollect, coinCollectVolume);
        if (UI) UI.UpdateDisplay();
        return coins;
    }
}

The solution multiplies the coin amount by the greed stat when greed is greater than 0, effectively implementing a passive bonus to coin collection.
