Node: UDP Input
Note that this node has slightly different behavior across different platforms due to fundamental differences in how *nix and Windows-based systems handle receiving broadcast messages. See Platform Dependent Networking Quirks for more information.
The UDP Input node allows you to receive UDP messages from devices on your network, and process those messages as appropriate by defining a piece of script that handles incoming messages.
messageSeparator character is stripped from the message and not included in the message provided for processing in the
callback. If the message separator is left empty, messages are separated by packet.
||LocalInterface||The local network adapter that will be used to UDP messages.|
||Number||The local port on which UDP messages will be received.|
||String||A single character to be used to indicate the end of a message, or leave empty to only have messages end on the end of a packet. Only the first codepoint provided is used to separate messages, the rest of this string is ignored. Keep in mind that special characters, like
||Any||A script in which a single additional variable,

Splitting values from messages
In situations where you are receiving multiple values in a single UDP message, for example a situation in which the
z of a set piece is being sent to Waltz, you may need to split the
message into separate values. This can be easily achieved with a small Script Expression in the
3,4,5, the following script can separate the
message and store them to three different Value Nodes named
var values = message.split(","); $.xValue.valueExpression = values; $.yValue.valueExpression = values; $.zValue.valueExpression = values;
