Make StackColors in Unity – Score Multiplier (Lesson 10)

In this lesson on how to make StackColor in Unity, we will be showing you how to create the score multiplying platforms that come after the finish line.

Multiplier.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Multiplier : MonoBehaviour
{
    [SerializeField] float multiplierValue;

    [SerializeField] Color multiplierColor;
    [SerializeField] Renderer[] myRends;

    void Start()
    {
        SetColor();
    }

    private void OnCollisionEnter(Collision collision)
    {
        Debug.Log(collision.gameObject.name + " hit");
        if(collision.transform.tag == "Pickup")
        {
            GameControllerStackColor.instance.UpdateMultiplier(multiplierValue);
        }
    }

    void SetColor()
    {
        
        for (int i = 0; i < myRends.Length; i++)
        {
            myRends[i].material.SetColor("_Color", multiplierColor);
        }
    }
}
