Rom name generation

Eduard

Hi,
I want to get a custom naming system which will have two characteristics:

1. Length of room name is 4 characters
   
2. It has only Upper or lower case characters
   

I thought to do it by specifying a function which from an set of values (not declared anywhere) takes timestamp as argument and select a unique name. This looks a bit complex.
Second idea was to have a server that issue name, but Ido not like this.

I do not know if photon has any builtin mechanism for customizing room name, so please if there is any let me know.

Eduard

Any help on this please?

why only 4 chars?

Eduard

because the players can read the code and enter. I can extend this, but first I need an approach how to solve it.

Hi @Eduard,

I guess the name should be randomly generated, shouldn't it? If so you can use Unity's Random functionality in order to create a 'random' number between 65 and 90 (uppercase characters) or 97 and 122 (lowercase characters), take a look at the ASCII table for more information. Then you can cast this number to a char and furthermore append this char to a string. In code this might look like the following:

public void CreateRandomName()
{
    string name = "";

    for (int counter = 1; counter <= 4; ++counter)
    {
        bool upperCase = (Random.Range(0, 2) == 1);

        int rand = 0;
        if (upperCase)
        {
            rand = Random.Range(65, 91);
        }
        else
        {
            rand = Random.Range(97, 123);
        }

        name += (char)rand;
    }

    Debug.Log(name);
}

Hi @Christian_Simon.
Yes name should be randomly generated. But if we generate it in unity we need to compare it again all other room names. At as the number of rooms increases I guess that the chance that generated string will not be unique, so there are a lot of for loops.
I hope someone from photon technical support will comment here to see this approach:
Like Christian said we generate string then we try to create room. if oncreateroomfailed is called then we repeat again. What are drawbacks of this?

When using this approach you have 52^4 different possibilities for the name which is a lot. So I guess it will take some time until you really got an already existing name. If this happens anyway you already have OnCreateRoomFailed callback to re-run the procedure and as far as I would say there is no problem with running this procedure even up to five times which is an absolutely worst case scenario.

@Eduard FYI:

my colleague @Christian_Simon is the best "someone from photon technical support".

ok thank you both for your help.
