Abstract base class for interacting with streams.
Description
StreamPeer is an abstract base class mostly used for stream-based protocols (such as TCP). It provides an API for sending and receiving data through streams as raw data or strings.
Note: When exporting to Android, make sure to enable the INTERNET
permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

Method Descriptions
Gets a signed byte from the stream.
Gets a signed 16-bit value from the stream.
Gets a signed 32-bit value from the stream.
Gets a signed 64-bit value from the stream.
int get_available_bytes() const 🔗
Returns the number of bytes this StreamPeer has available.
Array get_data(bytes: int) 🔗
Returns a chunk data with the received bytes. The number of bytes to be received can be requested in the bytes
argument. If not enough bytes are available, the function will block until the desired amount is received. This function returns two values, an Error code and a data array.
Gets a double-precision float from the stream.
Gets a single-precision float from the stream.
Array get_partial_data(bytes: int) 🔗
Returns a chunk data with the received bytes. The number of bytes to be received can be requested in the "bytes" argument. If not enough bytes are available, the function will return how many were actually received. This function returns two values, an Error code, and a data array.
String get_string(bytes: int = -1) 🔗
Gets an ASCII string with byte-length bytes
from the stream. If bytes
is negative (default) the length will be read from the stream using the reverse process of put_string.
Gets an unsigned byte from the stream.
Gets an unsigned 16-bit value from the stream.
Gets an unsigned 32-bit value from the stream.
Gets an unsigned 64-bit value from the stream.
String get_utf8_string(bytes: int = -1) 🔗
Gets a UTF-8 string with byte-length bytes
from the stream (this decodes the string sent as UTF-8). If bytes
is negative (default) the length will be read from the stream using the reverse process of put_utf8_string.
Variant get_var(allow_objects: bool = false) 🔗
Gets a Variant from the stream. If allow_objects
is true
, decoding objects is allowed.
Internally, this uses the same decoding mechanism as the @GlobalScope.bytes_to_var method.
Warning: Deserialized objects can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats such as remote code execution.
Puts a signed byte into the stream.
Puts a signed 16-bit value into the stream.
Puts a signed 32-bit value into the stream.
Puts a signed 64-bit value into the stream.
Error put_data(data: PackedByteArray) 🔗
Sends a chunk of data through the connection, blocking if necessary until the data is done sending. This function returns an Error code.
void put_double(value: float) 🔗
Puts a double-precision float into the stream.
void put_float(value: float) 🔗
Puts a single-precision float into the stream.
Array put_partial_data(data: PackedByteArray) 🔗
Sends a chunk of data through the connection. If all the data could not be sent at once, only part of it will. This function returns two values, an Error code and an integer, describing how much data was actually sent.
void put_string(value: String) 🔗
Puts a zero-terminated ASCII string into the stream prepended by a 32-bit unsigned integer representing its size.
Note: To put an ASCII string without prepending its size, you can use put_data:
put_data("Hello world".to_ascii_buffer())
Puts an unsigned byte into the stream.
Puts an unsigned 16-bit value into the stream.
Puts an unsigned 32-bit value into the stream.
Puts an unsigned 64-bit value into the stream.
void put_utf8_string(value: String) 🔗
Puts a zero-terminated UTF-8 string into the stream prepended by a 32 bits unsigned integer representing its size.
Note: To put a UTF-8 string without prepending its size, you can use put_data:
put_data("Hello world".to_utf8_buffer())
void put_var(value: Variant, full_objects: bool = false) 🔗
Puts a Variant into the stream. If full_objects
is true
encoding objects is allowed (and can potentially include code).
Internally, this uses the same encoding mechanism as the @GlobalScope.var_to_bytes method.
