Hi, I'm trying to get this code to work with my arduino, but I can't seem to be able to do this, as the sketch uses the old UDP library, instead of the new EthernetUDP library. If anyone can help me get this working I will be eternally grateful. I'm an arduino novice, so sorry for the question!

That doesn't mean that you can't describe your problem better than "this doesn't work".
Are you having problems compiling the code? Or, does the program not do what you want when it runs? What does it do? What do you want it to do?

Program refuses to compile due to the UDP library being superseded by the EthernetUDP library. I can't find a way to solve the issue of the library, so this is where I need assistance!
Program refuses to compile
I'm sure that you are getting more information than that. Share it, or solve the problem yourself.
What more information do you need? I can post code if you want. I click compile and this is all I get: I'm unsure of how to mitigate the issue of the updated library
What more information do you need?
The exact error messages you get.
I can post code if you want.
You already did. It uses a lot of libraries I don't have, so I can't compile it.
I click compile and this is all I get:
What is?
I'm unsure of how to mitigate the issue of the updated library
You still haven't defined what "the issue" is.
I posted a picture of the error! The code will not compile, because the code uses an old library, so I'm trying to find out how to utilise the newer library as I am unsure. Here is the code. I

ARTNET RECEIVER V3 plus SOFT PWM
This SCRIPT allows you to use arduino with ethernet shield or wifi shield and recieve artnet data. Up to you to use channels as you want.
It works with Arduino 023 software
If you have implemented ameliorations to this sketch, please, contribute by sending back modifications, ameliorations, derivative sketch. It will be a pleasure
to let them accessible to community
For VVVV patchers, please think to put a mainloop node in your patch: minimum frame rate is 40fps with bulbs. But do not go too much higher ( max 100 fps).
This sketch is part of white cat lighting board suite: /http://www.le-chat-noir-numerique.fr
wich is sending data to many different types of devices, and includes a direct communication in serial also with arduino likes devices
you may find whitecat interresting because its theatre based logic ( cuelist and automations) AND live oriented ( masters, midi, etc)

Why? The window contains text. Copy and paste the text.

As of Arduino 1.0, the Udp class in the Ethernet library has been renamed to EthernetUdp.
Is there some part of this that you don't understand? You need to rename the Udp class to EthernetUdp, as in:
EthernetUdp.begin(localPort);
Which then leads me to this error message. I'm not sure what to do from here.

There are three occurrences of Udp in your sketch. Clearly, you only bothered to change one of them. Why?

I did change all of them, yet it still gives the 'EthernetUdp was not declared in this scope error'

OK. It's because the stupid message is wrong. The class is defined in a file called EthernetUdp.h, but is actually called EthernetUDP. Morons!
Thanks for pointing that out! I'm still getting an error though, although this time its an unqualified-id error
