Question Pass parameter in action

hi, i have this method:

/// </summary>
/// <param name="callback">The callback:
/// * `0`: disconnect
/// * `1`: connect
/// * `2`: no microphone permission
/// </param>
/// <returns>
/// * `0`: failure
/// * `1`: success
/// Returns `0` when there is no microphone permission.
/// </returns>

public static int PICOCastInit(Action<int> callback)
{
return PXR_EnterprisePlugin.UPxr_PICOCastInit(callback);
}


How could I pass the action parameter with the value 1,
I tried this but it gives error :

Action<int> initCast;
PICOCastInit(initCast(1));

Thanks

 

Show the actual error.

Here are the actions with variables in C#: https://learn.microsoft.com/en-us/dotnet/api/system.action-1?view=net-7.0&redirectedfrom=MSDN

 

This error: argument cannot be converted from void to System.Action<int>

 

Ah, I think it is asking to use the Action itself as a parameter. Now you are initiating the action while passing it through.
PICOCastInit(initCast); might work

 

It works but the callback returns zero, that's why I was trying to send the action with the parameter 1

 

Check back on the documentation or ask on the pico dev forums

 

This doesn't make much sense. The callback gets an int value from the caller. So whoever actually invokes the callback is passing an int argument to your callback.

A quick google search gave me this which is probably related to your code. As you can read in the documentation when the callback is called, it would pass a value of 0, 1 or 2 to your callback method. This is not an argument you specify. It's a value you get back.

So you would do something like

Code (CSharp):

1. PICOCastInit(OnInitCast);
2.  
3.  
4. // [ ... ]
5.  
6. void OnInitCast(int aState)
7. {
8.     Debug.Log("InitCast state: " + aState);
9. }

So a value of 0 would indicate that you're disconnected, a value of 1 indicates that you are connected and a value of 2 means it doesn't have permissions to use the mic. Again, this is a callback and that int value is a result value, not an argument that you have to specify.

 

A ok ok, thanks.
Thanks again to both of you for the help.
