In-Depth Information
Let's make our own version. Create a new function in this plugin and name
it
myFling
. Copy the version from
EZPlugin
into the body of the function, and it
will look like this:
public static void
myFling(LivingBase player,
LivingBase entity,
double
factor) {
double
pitch = (player.getPitch() + 90.0F) *
Math
.PI / 180.0D;
double
rot = (player.getRotation() + 90.0F) *
Math
.PI / 180.0D;
double
x =
Math
.sin(pitch) *
Math
.cos(rot);
double
z =
Math
.sin(pitch) *
Math
.sin(rot);
double
y =
Math
.cos(pitch);
entity.moveEntity(x * factor, y + 0.5, z * factor);
}
And change the
0.5
on the last line to some other number, say
1.5
.
Then change the call to
myFling
instead of
fling
:
...
Canary.getServer().addSynchronousTask(
new
CowTask(victim));
myFling(player, victim, 3);
victim.setFireTicks(600);
...
Run
build.sh
to make sure it still works, and commit your changes:
$
git commit -a -m 'Moved vector calculation'
[play 411208c] Moved vector calculation
1 file changed, 9 insertions(+), 1 deletion(-)
Now with that safely in a snapshot in the play branch, let's go back and take
a look at the original:
$
git checkout master
Switched to branch 'master'
And now the version of
CowShooter.java
on disk is the version in the
master
reality.
Take a look at it and see. One note of caution: Git changed the text file on
disk. The version in your editor's buffer might be the old one. Most editors
are savvy enough to realize when a file has changed out from under them,
but how that's handled is up to the editor.
Now back here in
master
, let's change the cow shooter to shoot creepers instead.
In both
CowShooter.java
and
CowTask.java
, add the import for
Creeper
at the bottom
of the list of imports:
import
net.canarymod.api.entity.living.monster.Creeper;
// Add this line
