Game development, the movement of other players on the interface can be seen in real time, how is this backend realized?

such as
how do online games save the real-time location of user roles and Synchronize?
now design a game combined with the actual map
database using mongoDB
data table with a location field to record the user"s current location so that others can get
when they get the surrounding online players. But the user moves very frequently, so it should not be the user to move on the update database.
how should it be designed / implemented here?
just ask for ideas!
Thank you!


suggest to know: the keyword "online game Synchronize mode (frame Synchronize and status Synchronize)"


has not played a game, explain my understanding, Daniel do not spray

this must be socket.. In any case, your
1 is not real-time
2 server pressure.


under a long connection, the location data is broadcast
