Item View Modules

Creating a custom Item View Module is possible, simply Inherit the Item View Module base class

Example:

/// <summary>
/// An item box component to display an amount.
/// </summary>
public class AmountItemView : ItemViewModule
{
    [Tooltip("The amount text.")]
    [SerializeField] protected Text m_AmountText;
    [Tooltip("Do not show amount if it is 1 or lower.")]
    [SerializeField] protected bool m_HideAmountIfSingle;

    /// <summary>
    /// Set the value.
    /// </summary>
    /// <param name="info">The item info.</param>
    public override void SetValue(ItemInfo info)
    {
        if (m_HideAmountIfSingle && info.Amount <= 1) {
            m_AmountText.text = "";
        } else {
            m_AmountText.text = $"x {info.Amount}";
        }
    }

    /// <summary>
    /// Clear the value.
    /// </summary>
    public override void Clear()
    {
        m_AmountText.text = "";
    }
}
