I'll do a
gitadd
on the new
CreeperCowTimer.java
file so my changes can be tracked.
Great. Now we need some way of setting that private cow object. We'll hook
this up to the
spawnCows
function later, but right now we'll just pass in a cow
that's been spawned already. For that, we'll use the constructor function:
CreeperCowTimer(Cow aCow) {
cow = aCow;
}
Next we need to add a jump command to the plugin for our testing. Now we'll
go back into the
spawnCows
function and add the spawned cows to the
ArrayList
.
Then, in the jump command we can go through the list and get each of the
spawned cows to jump toward us.
So we'll start with this:
Cow cow = (Cow)spawnEntityLiving(loc, EntityType.COW);
cowList.add(cow);
Then we'll add a test command:
@Command(aliases = {
"testjump"
},
description =
"Test cow jumping"
,
permissions = {
""
},
min = 1,
// Number of arguments
toolTip =
"/testjump"
)
public void
testJumpCommand(MessageReceiver caller,
String[]
args) {
if
(caller
instanceof
Player) {
Player me = (Player)caller;
for
(Cow c : cowList) {
c.jump(me.getLocation());
}
}
}
Oops, that's not going to work.
We shouldn't have kept a list of cows. We really need to keep track of
Creeper-
CowTimer
objects, as that will get us the
jump()
function and the other guts that
we need to write, as well as the
Cow
itself.
And if we do that, we should probably change the list to be a
HashMap
instead
of an
ArrayList
so we can look up the
CreeperCowTimer
objects by their
Cow
, as
that's what we'll get from events and spawning and such. We'll need to redo
a few things now.
Make a list of things we need to change for this, and come on back once you
have it.
