Public Function cant be found in OnClick Event-CodePudding

So I have an Inventory and the Items have MataData, that I am scanning for. Although when I try to hook up the public void to the OnClick selection on the Button, it does not show up, why? Code Snipped:

public void ScanForFlashlightMetaData(string type, string Flashlight)
    {
        foreach (Slot slot in inventory)
        if (slot.type == type && slot.metaData == Flashlight)
        {
            Debug.Log("Test");
        }
    }

CodePudding user response：

Callback functions assigned to ButtonClickEvent can only take zero or one parameters (which is why it shows up when you remove them).

Try looking here for workarounds, or consider creating a custom Button class that uses the generic UnityEvent<T0, T1, ...> which supports up to four arguments.
