Hello FİREBASE-İtemtable I have a question.

My English is bad. Sorry.

I built the Firebase structure. What I want to do. Change the child values ​​in the database. How do I delete or not add. I want to update?

Example: User A killed user B.B can have a value of 0. It was 100 before.

Or:

Money: 1300

The new value is 1400.

Please answer. My gratitude.

HELPPPP :(

Its very hard to understand your question but I use firebase with construct 3 so I'll try to help.

I think you're asking how to update a field in a firestore document? You're probably trying to set one field of a document and finding the whole document is gone except for the one field. Make sure you use the "update" function and not the "set" function. The documentation is here: https://firebase.google.com/docs/firestore/manage-data/add-data#update_fields_in_nested_objects

Example:

db.collection("users").doc("b").update({
 health : 0
});
