I'm not sure what's the difference, why are they used. I use the print to make a message appear in the console but what's the point in using warn() and error()? If I do use error does it stop the script or will it just come up as red in the output?

The reason there are 3 methods of logging to the output is so developers can filter the messages to find errors or self warnings in their scripts. For example if I had a script and there was a place in the script it should never get to, you can use a warning or an error to say it got to a place it shouldn't. The main use is to filter between messages for developers, print can also be used for reassuring the developer the script has got to a certain point. Error will stop the script like any other error, and will state the line the error outputs as well as the defined message. Read more about them here.
