Solved Packet Help (If You Would Be So Kind!)

Hello,
Can someone give me some help using packets. I'd like to create a range of effects using particle effects such as 'blood' effect, fire particle effect, etc. I was wondering if someone could perhaps explain how the packet system works, perhaps giving an example. If someone could use the 'blood' effect as an example, that would be very helpful.
Thanks,
jakesully

 

This requires some epic (possibly advanced) trigonometry just to make it look cool.

But to start off, for 1.7:

Code:

PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles(String particleType, float xPos, float yPos, float zPos, float xOffset, float yOffset, float zOffset, float something I think amplifier or range, float iForgot);

For example:

Code:

Location loc = player.getLocation();
PacketPlayOutWorldParticles packet = new PacketPlayOutWorldParticles("happyVillager",
                                            ((float) (loc.getX())),
                                            ((float) (loc.getY())),
                                            ((float) (loc.getZ())),
                                        0,0,0, 1, 0);

@Agentleader1
What is the PacketPlayOutWorldParticle class? Where can I import it from?

 

@Jakesully123456
It's NMS (net minecraft server), and it's import is
import net.minecraft.server.v1_7_R4.PacketPlayOutWorldParticles;

 

@Agentleader1 what would be the import on 1.8.3 spigot? (1.8 Ro.1-SNAPSHOT)

 

@Jakesully123456 v1_8_R1

But in that case:

Code:

new PacketPlayOutWorldParticles(EnumParticle paramEnumParticle, boolean paramBoolean, float paramFloat1, float paramFloat2, float paramFloat3, float paramFloat4, float paramFloat5, float paramFloat6, float paramFloat7, int paramInt, int[] paramArrayOfInt);

When the templates in eclipse (auto completes) show up, use it, and leave the extra variables that aren't required in the 1.7 particles the way they were given by eclipse.

 

@Agentleader1
I'm using this line to import:

Code:

import net.minecraft.server.v1_8_R1.PacketPlayOutWorldParticles;

But getting net.minecraft cannot be resolved?
Do I need to add it as a dependency/repository? If so, how?

 

@Jakesully123456 If you mean adding the spigot-1.8-snapshot into the external archives, the answer is "OF COURSE!"

 

@Agentleader1 No, I have done that of course!
This line is in my imports, I have the spigot snapshot imported, of course.

Code:

import net.minecraft.server.v1_8_R1.PacketPlayOutWorldParticles;

But this line is errored under "The import net.minecraft cannot be resolved"

 

@Jakesully123456 Send me the build.

 

@Agentleader1 If by build you meant pom file, here. If not, could you elaborate?

@Jakesully123456 Build means the final decompiled jar file.

 

@Agentleader1 I see, not comfortable with sharing my code, I'm awfully paranoid. Its also very big. Is there any obvious reason why I might not have access to the net.minecraft package? I'm using Maven, what repositories and dependencies should I have in order to access the net.minecraft package, I am running on spigot 1.8 if that makes a difference.

I don't mean to be distrustful, and I am very grateful for any help available.

 

@Jakesully123456 Not that build lol, I meant the spigot build.

 

Spigot build? Could you please elaborate @Agentleader1
I have imported "1.8-R0.1-SNAPSHOT" from "https://hub.spigotmc.org/nexus/content/groups/public/"
This is shown in my pom.xml file above.

 

@Jakesully123456 How do I need to elaborate? I'm just asking for you to send me the full spigot jar file build.


//Edit:
Easier solution: world.playEffect(location, Effect.TYPE_OF_EFFECT_HERE, int offset);

 

@Agentleader1 I'm sorry, I'm not sure if you want my server jar, or what?

 

@Jakesully123456 EXACTLY, I want to server jar, of course I'm assuming it is the spigot 1.8 snapshot build you mentioned.

 

@Agentleader1 https://www.dropbox.com/s/py05rzx6tp0jq91/spigot.jar?dl=0

 

I imported

Import Node (open) Import Node (close)

import net.minecraft.server.v1_8_R1.PacketPlayOutWorldParticles;

just fine with no errors. ;-;

 

@Agentleader1 is there nothing else I need to do? No additional repositories?
What repositories are in ur pom?

 

@Jakesully123456 I honestly don't know, take a screenshot of your implemented external archives (including it's order).

 

@Agentleader1 well, I sent my pom.xml just a few posts ago but here, image of all dependencies.

@Jakesully123456 It says you have bukkit implemented. If it's not the spigot build, replace it with the spigot build, and MAKE SURE to have the external archive as FIRST in the order.

 

@Agentleader1 how do I ensure its spigot? And how do I make sure its first in the order?

 

@Jakesully123456 Locate spigot build and see if that is what is said in your list of implemented apis. According to your foto, it looks like it already is.

 

OK, and its definitely the first on the list I sent you, so what else could be the issue?
@Agentleader1

 

@Jakesully123456 Just keep refreshing? Or restart Eclipse.

 

@Agentleader1 I have restarted Eclipse. Nothing.
This image shows the contents of the spigot external archive, I see no net.minecraft, why is it not there?
