Why you should clear the tag "PlayerName" before?

[Alpha2020]

Othervise it will make copies of the same player

[Rndm_Nikzea]

What is when two players have the same Name?

[Alpha2020]

Good question, the answer is before saving the name to TinyDB use this block

[Rndm_Nikzea]

What is the get value standing for?

[Alpha2020]

The get value is the parameter for the when FirebaseDB1 .TagList.

[Rndm_Nikzea]

Would this function?

[Alpha2020]

Change that to Firebase

[Rndm_Nikzea]

And the rest would work?

How to Create a Scoreboard

Without going into the blocks: Firebase data (WordZazzle at root): [image] Firebase Rules: "rules:" { "WordZazzle": { ".read": true, ".indexOn": ".value" } } Web Url: https:///<FirebaseURL>/WordZazzle.json?orderBy="$value"&limitToLast=3 responseContent (returns the top three, but NOT in order): { "Lini": "\"123456\"", "Thivia": "\"1234\"", "Tia": "\"12345\"" } You will then have to get the responseContent into a list or dictionary and sort by the scores

Set LimitToLast to 1 to return the top score

So my problem is i want to get 2 different values out of the server but you can only get 1 value when you use the "get value" block

[ABG]

You could get the first tag, then when the tag and value arrive, save them both and ask for the next tag that you wanted.

[Rndm_Nikzea]

What would be the code for getting an tag

[TIMAI2]

@Rndm_Nikzea

i want to get 2 different values out of the server

Which two values? Name and score ?

Use the REST method as above and it will return both. (given your data is structured accordingly)
