# Conversa Plugin

Reference Link: <https://github.com/enriquemorenotent/unity-conversa-support/wiki>

## Initial Updates to DiaManager.cs

{% code fullWidth="true" %}

```csharp
// Add to top of the script
using System;
using Conversa.Runtime.Events;
```

{% endcode %}

## Initial Updates to DiaTrigger.cs

{% code fullWidth="true" %}

```csharp
// Add to top of the script
using Conversa.Runtime;
using Conversa.Runtime.Events;
using Conversa.Runtime.Interfaces;

...

//Inside Class
[SerializeField] private Conversation conversation;
private ConversationRunner runner;

...

//Setting things up
private void Start()
{
	runner = new ConversationRunner(conversation);
	runner.OnConversationEvent.AddListener(HandleConversationEvent);
}


```

{% endcode %}

## Buckle up, Time for Delegates!

In javascript, you can pass a function as a variable. Not in C#. Now, you have to create a delegate. This video, up to 3:28 will explain the shenanigans. If you go past that, you will get confused.

Just the additional Script added for DiaManager.

{% code fullWidth="true" %}

```csharp
//Adding Namespaces required
using System;

...

//Storing the function from the conversation starter script into this one
public delegate void NextMessageDelegate();
private NextMessageDelegate NextMessageFunction;

//Initializing it
private void Start()
{
...
    NextMessageFunction = NextMessage;
}

private void NextMessage()
{
    Debug.Log("Testing out this new thing, yo.");
}

//Having it as a separate function so you can drag and drop it into the PlayerInputComponent
//if the PlayerInputComponent is set to "Invoke Unity Events"
public void Advance(InputAction.CallbackContext ctx)
{
    if (ctx.performed)
    {
        NextMessageFunction();
    }
}

//In the Show Message option that opens up the Dialogue box
public void Show(string actor, string message, Sprite avatar, Action onContinue)
{
    ...
    NextMessageFunction = () => onContinue();
}

```

{% endcode %}

Here are some failures I got when trying to set "onContinue" to a function in the DiaManager:

{% code fullWidth="true" %}

```csharp
NextMessageFunction = onContinue();

NextMessage = onContinue;
```

{% endcode %}
