In-Depth Information
getServer() call returns something (it's actually a Server ). Once we have that, we
can then call any of the Server 's functions. In this case, we're calling the Server 's
broadcastMessage() function, passing in a string argument named msg . Take a
look at this line in action:
To make it clearer, you could break up this chain of function calls into sepa-
rate pieces, which would look something like this:
instance = Canary.instance();
server = instance.getServer();
See? It's just a set of function calls. With me so far?
You can define a function yourself. Here's an example that defines a new
function named castIntoBlackHole . Watch closely, because you'll be doing this
on your own next.
public static void castIntoBlackHole( String playerName)
// Do something interesting with the player here...
There is a bit more noise here than in the cake example. Let's see what all
this stuff means.
public means that any other part of the program can use it, which for now
you want to be the case.
static means you can call this function all by itself (not like a plugin; we'll
see the difference and what that means in the next chapter).
void means this function is going to run a couple of instructions, but not
give you any data back—it won't “return” any values to the caller.
