Description
|
|
-----------
|
|
|
|
Manages the connection to network peers. Assigns unique IDs to each client connected to the server. See also :ref:`MultiplayerAPI<class_MultiplayerAPI>`.
|
|
|
|
\ **Note:** The high-level multiplayer API protocol is an implementation detail and isn't meant to be used by non-Godot servers. It may change without notice.

Enumerations

------------
|

|
|
|
|
:ref:`TransferMode<enum_NetworkedMultiplayerPeer_TransferMode>` **TRANSFER_MODE_UNRELIABLE** = ``0``
|
|
|
|
Packets are not acknowledged, no resend attempts are made for lost packets. Packets may arrive in any order. Potentially faster than :ref:`TRANSFER_MODE_UNRELIABLE_ORDERED<class_NetworkedMultiplayerPeer_constant_TRANSFER_MODE_UNRELIABLE_ORDERED>`. Use for non-critical data, and always consider whether the order matters.
|
|
|
|
.. _class_NetworkedMultiplayerPeer_constant_TRANSFER_MODE_UNRELIABLE_ORDERED:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`TransferMode<enum_NetworkedMultiplayerPeer_TransferMode>` **TRANSFER_MODE_UNRELIABLE_ORDERED** = ``1``
|
|
|
|
Packets are not acknowledged, no resend attempts are made for lost packets. Packets are received in the order they were sent in. Potentially faster than :ref:`TRANSFER_MODE_RELIABLE<class_NetworkedMultiplayerPeer_constant_TRANSFER_MODE_RELIABLE>`. Use for non-critical data or data that would be outdated if received late due to resend attempt(s) anyway, for example movement and positional data.
|
|
|
|
.. _class_NetworkedMultiplayerPeer_constant_TRANSFER_MODE_RELIABLE:
|
|
|
|
.. rst-class:: classref-enumeration-constant
|
|
|
|
:ref:`TransferMode<enum_NetworkedMultiplayerPeer_TransferMode>` **TRANSFER_MODE_RELIABLE** = ``2``
|
|
|
|
Packets must be received and resend attempts should be made until the packets are acknowledged. Packets must be received in the order they were sent in. Most reliable transfer mode, but potentially the slowest due to the overhead. Use for critical data that must be transmitted and arrive in order, for example an ability being triggered or a chat message. Consider carefully if the information really is critical, and use sparingly.
