Enumerations

enum WriteMode:

WriteMode WRITE_MODE_TEXT = 0

Tells the channel to send data over this channel as text. An external peer (non-Godot) would receive this as a string.

WriteMode WRITE_MODE_BINARY = 1

Tells the channel to send data over this channel as binary. An external peer (non-Godot) would receive this as array buffer or blob.

enum ChannelState:

ChannelState STATE_CONNECTING = 0

The channel was created, but it’s still trying to connect.

ChannelState STATE_OPEN = 1

The channel is currently open, and data can flow over it.

ChannelState STATE_CLOSING = 2

The channel is being closed, no new messages will be accepted, but those already in queue will be flushed.

ChannelState STATE_CLOSED = 3

The channel was closed, or connection failed.

Property Descriptions

WriteMode write_mode = 1

• void set_write_mode ( WriteMode value )

• WriteMode get_write_mode ( )

The transfer mode to use when sending outgoing packet. Either text or binary.

Returns the maxRetransmits value assigned to this channel during creation.

Will be 65535 if not specified.

String get_protocol ( ) const

Returns the sub-protocol assigned to this channel during creation. An empty string if not specified.

ChannelState get_ready_state ( ) const

Returns the current state of this channel, see ChannelState.

bool is_negotiated ( ) const
