Greetings folks,
As a game of what can be done and fun with development…I present the 4,000 Characters or Less Coding for plugins! Just paste a code tag with your plugin that is functional. Here are the rules:
Let’s see what folks can come up with
EnderBlock 0.2
package org.spongepowered.enderblock;
import org.spongepowered.api.entity.living.monster.Enderman;
import org.spongepowered.api.event.Listener;
import org.spongepowered.api.event.block.ChangeBlockEvent;
import org.spongepowered.api.plugin.Plugin;
@Plugin(id = "enderblock", name = "EnderBlock", version = "0.2")
public class EnderBlock {
@Listener
public void onBreakBlock(ChangeBlockEvent.Break event) {
if (event.getCause().first(Enderman.class).isPresent()) {
event.setCancelled(true);
}
}
}
My head hurts after staring at the code for too long, brunch time!
I could use wildcards in imports and combine the annotation with the methods and make if statements without the curly brackets. But that would break the Sponge coding guidelines.
Edit: Oops! I thought that I had to make your code smaller!
I think so yes because if you remove the empty lines you are not following the:
Oh sounds like fun, how about VoxelSniper in 50 lines.
Supports balls, discs and voxels, sizes can be floating point numbers.
Your brush/size/material is set by the command ‘/brush (ball|disc|voxel):size:material’.
For example ‘/brush ball:25:dirt’ will place down balls of dirt with a radius of 25 blocks whereever you click.
As an aside: something funky is up with one of EyeLocationData or BlockRay.from(Entity), as far as I can tell the eye location is supposted to be the entity location + the eye offset, but I was always just getting the offset when using the BlockRay. So a minor fix is needed there for this to work. I changed BlockRay:501 to
position = location.getPosition().add(data.get().eyeLocation().get());
But I’m pretty sure the eye location is supposed to be the correct location so some investigation is needed for that. Otherwise enjoy, although I do think this would be more fun as a code golf-styled challenge with a character limit rather than a line limit.

@org.spongepowered.api.event.Listener
public void onInteract(org.spongepowered.api.event.action.InteractEvent e) {
org.spongepowered.api.entity.living.player.Player p = e.getCause().first(org.spongepowered.api.entity.living.player.Player.class).orNull();
if (p != null && p.getItemInHand().isPresent() && p.getItemInHand().get().getItem().equals(org.spongepowered.api.item.ItemTypes.ARROW)) {
String brush = brushes.get(p.getUniqueId());
if (brush == null || !java.util.regex.Pattern.matches("(ball|voxel|disc):[\\d]+(:?\\.[\\d]+)?:[a-z]+", brush)) brush = "ball:1:stone";
BlockRayHit<org.spongepowered.api.world.World> target = BlockRay.from(p).filter(BlockRay.onlyAirFilter()).end().get();
double size = Double.parseDouble(brush.split(":")[1]) - 0.5;
BlockState mat = game.getRegistry().getType(BlockType.class, brush.split(":")[2]).or(BlockTypes.STONE).getDefaultState();
for (int x = com.flowpowered.math.GenericMath.floor(-size); x < size; x++) {
for (int z = com.flowpowered.math.GenericMath.floor(-size); z < size; z++) {
for (int y = com.flowpowered.math.GenericMath.floor(-size); y < size; y++) {
if (brush.startsWith("disc") && y != 0) continue;
if (brush.startsWith("voxel") || x * x + y * y + z * z < size * size)
p.getWorld().setBlock(target.getBlockX() + x, target.getBlockY() + y, target.getBlockZ() + z, mat);
}
}
}
}
}
}
Exactly 50 lines, and yes the maximum line length is 150.
Iirc Sponge follows Googles Java Style, so no wildcard imports allowed.
EDIT: Is Voxelsniper available for Sponge?
Yes I had to take that liberty because otherwise the imports were 34 lines long (If I remove the fully qualified classes as well).
EnderBlock 3 (under new rules!)
package org.spongepowered.enderblock;
@org.spongepowered.api.plugin.Plugin(id = "eb", name = "EB", version = "3")
public class EB {
@org.spongepowered.api.event.Listener
public void onBreakBlock(org.spongepowered.api.event.block.ChangeBlockEvent.Break e) {
if (e.getCause().first(org.spongepowered.api.entity.living.monster.Enderman.class).isPresent()) {
e.setCancelled(true);
}
}
}
Another entry of my EnderBlock. Can’t really lessen it’s characters without sacrificing the plugin’s name
package org.spongepowered.enderblock;
@org.spongepowered.api.plugin.Plugin(id = "eb", name = "EB")
public class EB {
@org.spongepowered.api.event.Listener
public void b(org.spongepowered.api.event.block.ChangeBlockEvent.Break e) {
if (e.getCause().first(org.spongepowered.api.entity.living.monster.Enderman.class).isPresent()) {
e.setCancelled(true);
}
}
}
Final entry using new any of Cause I just pushed (not just for golf >.>)
package org.inspirenxe.eb;
@org.spongepowered.api.plugin.Plugin(id = "eb", name = "EB")
public class EB {
@org.spongepowered.api.event.Listener
public void b(org.spongepowered.api.event.block.ChangeBlockEvent.Break e) {
if (e.getCause().any(org.spongepowered.api.entity.living.monster.Enderman.class)) {
e.setCancelled(true);
}
}
}
Excellent, I love code golfing! I can remove the star imports then and fully conform to the code style. I also added the voxeldisc brush and reduced my entry from 3900 characters to 2852 characters.

}Ignite - If an ignitable Entity is set on fire (vanilla: creeper and TNT minecart), it will ignite.
