How can i upgrade the fire rate and damage in my upgrade menu

Hi I am new to unity and I know very little about coding and I don’t know how can I upgrade the fire rate and the damage from my upgrade menu this is a game from brackeys 2d platformer course a link to it:1. How to make a 2D Platformer - Basics - Unity Tutorial - YouTube

any help would be appreciated thanks a lot in advance :slight_smile:

}
if (healthText == null)

{

Upgrade menu script:

using UnityEngine;
using UnityEngine.UI;
public class UpgradeMenu : MonoBehaviour
{
[SerializeField]
private Text healthText;
[SerializeField]
private Text speedText;
[SerializeField]
private float healthMultiplier = 1.3f;
[SerializeField]
private float movementSpeedMultiplier = 1.3f;
[SerializeField]
private int upgradeCost = 50;
private PlayerStats stats;
void OnEnable()
{
stats = PlayerStats.instance;
UpdateValues();
}
void UpdateValues()
{
healthText.text = "HEALTH: " + stats.maxHealth.ToString();
speedText.text = "SPEED: " + stats.movementSpeed.ToString();
}
public void UpgradeHealth()
{
if (GameMaster.Money < upgradeCost)
{
AudioManager.instance.PlaySound("NoMoney");
return;
}
stats.maxHealth = (int)(stats.maxHealth * healthMultiplier);
GameMaster.Money -= upgradeCost;
AudioManager.instance.PlaySound("Money");
UpdateValues();
}
public void UpgradeSpeed()
{
if (GameMaster.Money < upgradeCost)
{
AudioManager.instance.PlaySound("NoMoney");
return;
}
stats.movementSpeed = Mathf.Round(stats.movementSpeed * movementSpeedMultiplier);
GameMaster.Money -= upgradeCost;
AudioManager.instance.PlaySound("Money");
UpdateValues();
}
}

any help would be appreciated a lot :wink:

Assuming you want to have this work just like the Health and Speed upgrades here is a solution.

First add a new button and text for the fire rate to your upgrade menu, just like you did for the health and speed upgrades.

Since the fire rate is linked to the weapon add a reference to the Weapon class to UpgradeMenu. Also add a multiplier and reference to the menu text for the fire rate.

    [SerializeField]
    private Weapon weapon;
    [SerializeField]
    private float fireRateMultiplier = 1.3f;
    [SerializeField]
    private Text fireRateText;

Assign the references for the Weapon and Text in the inspector (editor).

Add a method for upgrading the fire rate of your weapon to the UpgradeMenu. Call this method from the new button you’ve added.

    public void UpgradeFireRate()
    {
        // TODO: You should create some methods instead of copying 
        // the same code into each upgrade option.
        if (GameMaster.Money < upgradeCost)
        {
            AudioManager.instance.PlaySound("NoMoney");
            return;
        }
        weapon.fireRate = Mathf.Round(weapon.fireRate * fireRateMultiplier);
        GameMaster.Money -= upgradeCost;
        AudioManager.instance.PlaySound("Money");
        UpdateValues();
    }

Update the text for the fire rate in UpdateValues() of UpdateMenu.

    private void UpdateValues()
    {
        healthText.text = "HEALTH: " + stats.maxHealth.ToString();
        speedText.text = "SPEED: " + stats.movementSpeed.ToString();
        fireRateText.text = "FIRE RATE: " + weapon.fireRate.ToString();
    }

This would be the easiest solution I think. You can also move the fire rate to your PlayerStats class. This would allow you to keep the fire rate upgrades even after changing weapons.
