From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Tue, 29 Aug 2017 23:58:48 -0400 Subject: [PATCH] Expand World.spawnParticle API and add Builder Adds ability to control who receives it and who is the source/sender (vanish API) the standard API is to send the packet to everyone in the world, which is ineffecient. This adds a new Builder API which is much friendlier to use. diff --git a/src/main/java/com/destroystokyo/paper/ParticleBuilder.java b/src/main/java/com/destroystokyo/paper/ParticleBuilder.java new file mode 100644 index 0000000000000000000000000000000000000000..0000000000000000000000000000000000000000 --- /dev/null +++ b/src/main/java/com/destroystokyo/paper/ParticleBuilder.java @@ -0,0 +0,0 @@ +package com.destroystokyo.paper; + +import com.google.common.collect.Lists; +import org.bukkit.Color; +import org.bukkit.Location; +import org.bukkit.Particle; +import org.bukkit.World; +import org.bukkit.entity.Player; +import org.bukkit.util.NumberConversions; + +import java.util.Collection; +import java.util.List; +import org.jetbrains.annotations.NotNull; +import org.jetbrains.annotations.Nullable; + +/** + * Helps prepare a particle to be sent to players. + * + * Usage of the builder is preferred over the super long {@link World#spawnParticle(Particle, Location, int, double, double, double, double, Object)} API + */ +public class ParticleBuilder { + + private Particle particle; + private List receivers; + private Player source; + private Location location; + private int count = 1; + private double offsetX = 0, offsetY = 0, offsetZ = 0; + private double extra = 1; + private Object data; + private boolean force = true; + + public ParticleBuilder(@NotNull Particle particle) { + this.particle = particle; + } + + /** + * Sends the particle to all receiving players (or all).
