[CreateAssetMenu(fileName = "NewItem", menuName = "Items/NewItem", order = 1)]
public class NewBehaviourScript : ScriptableObject
{
    [HideInInspector]
    public string buy = "BUY";
    [HideInInspector]
    public string OWNED = "EQUIP";
    [HideInInspector]
    public Color equipColor = new Color(0.53333f, 1.00000f, 0.30196f);
    [HideInInspector]
    public Color buyColor = new Color(1.00000f, 0.10196f, 0.10196f);
    public new string name;
    public float price;
    public Sprite Image;
    public bool Owned;
    public float spreadAmmount;
    public float damage;
    public bool equiped;
}

using TMPro;

public class DisplayItems : MonoBehaviour
{
    public MoneyUpdate curency;
    public NewBehaviourScript item;
    public TextMeshProUGUI Cost;
    public TextMeshProUGUI ItemName;
    public Image image;
    public TextMeshProUGUI buttonText;
    public Button button;

    private void Update()
    {
        if (item.Owned)
        {
            buttonText.text = "" + item.OWNED;
            ColorBlock cb = button.colors;
            cb.normalColor = item.equipColor;
            button.colors = cb;
        }
        else
        {
            buttonText.text = "" + item.buy;
            ColorBlock cb = button.colors;
            cb.normalColor = item.buyColor;
            button.colors = cb;
        }
    }
    void Start()
    {
        Cost.text = "$" + item.price;
        ItemName.text = "" + item.name;
        image.sprite = item.Image;
    }
    public void BuyWeapon()
    {
        if (!item.Owned && item.price <= curency.money)
        {
            item.Owned = true;
            PlayerPrefs.SetInt("Money", (int)curency.money - (int)item.price);
        }
        if (item.Owned)
        {
            item.equiped = true;
        }
