After the livestream #4, if the initial weapon is Knife, then after clicking on the button to receive the second weapon, the second number of weapons on Inventory is 5 (EX: Garlic will appear 5 controllers and 5 image. ). Everyone can help me thank you. It is code of PlayerInventory :

public class PlayerInventory : MonoBehaviour
{
    public struct Slot
    {
        public Weapon weapon;
        public Image UI;
    }
    // public List<Slot> weaponSlots = new List<Slot>(6);

    public List<Weapon> weaponSlots = new List<Weapon>(6);
    public List<Image> weaponsUISlot = new List<Image>(6);
    public List<PassiveItem> passiveItemSlots = new List<PassiveItem>(6);
    public int[] passiveItemLevels = new int[6];
    public List<Image> passiveItemUISlots = new List<Image>(6);

And it is code of spawnweapon:

        {

            return;
        }
        // Get the type of the weapon we want to spwan
        Type weaponType = Type.GetType(weapon.behaviour);

        if(weaponType != null)
        {
            GameObject go = new GameObject(weapon.baseStats.name + "Controller");
            Weapon spawnedWeapon = (Weapon)go.AddComponent(weaponType);
            print(weapon.name + " is spawn");
            spawnedWeapon.Initialise(weapon);
            spawnedWeapon.transform.SetParent(transform); // vk la con cua nguoi choi
            spawnedWeapon.transform.localPosition = Vector2.zero;
            inventory.AddWeapon(weaponIndex, spawnedWeapon);

            weaponIndex++;
        }
        else
        {
            Debug.LogWarning(string.Format("Invalid weapon type for {0}.", weapon.name));
        }

    }

It looks like your code is a mix of the old system and the new system. Have you watched Part 15? There are parts of the video where you can refer to the new PlayerInventory code.

I have seen Part 15 but I’m currently following your stream. The code you run when the stream does not Error, so you can see the above code and fix the error to help me.

Which function are you calling to add your weapon? AddWeapon() or SpawnWeapon()?

After clicking the Button, the Spawnweapon () function will be called to spawn the new weapon.and in spawnweapon () have: Inventory.addweapon (Weaponindex, Spawnedweapon); to add weapon.

Can you add the following to your SpawnWeapon():

public void SpawnWeapon(WeaponData weapon)
    {
        print("Weapon spawned: " + weapon.name);
        if (weaponIndex >= inventory.weaponSlots.Count)// co the bang -1 vi list bat dau tu 0
        {
            Debug.LogError("Inventory slots already full");
            return;
        }
        // Get the type of the weapon we want to spwan
        Type weaponType = Type.GetType(weapon.behaviour);

        if(weaponType != null)
        {
            GameObject go = new GameObject(weapon.baseStats.name + "Controller");
            Weapon spawnedWeapon = (Weapon)go.AddComponent(weaponType);
            print(weapon.name + " is spawn");
            spawnedWeapon.Initialise(weapon);
            spawnedWeapon.transform.SetParent(transform); // vk la con cua nguoi choi
            spawnedWeapon.transform.localPosition = Vector2.zero;
            inventory.AddWeapon(weaponIndex, spawnedWeapon);

            weaponIndex++;
        }
        else
        {
            Debug.LogWarning(string.Format("Invalid weapon type for {0}.", weapon.name));
        }

    }

Then show me your Console window when you add a new weapon.

I suspect you have multiple copies of some scripts attached. That’s likely what is causing this issue.

Add the following line below the previous print statement and show me the Console:

print( new System.Diagnostics.StackFrame(1, true).GetMethod().Name );

This will tell us which function is calling your SpawnWeapon multiple times.
