Solved ParticleEffect & Reflections

I need an updated link of the reflections class for 1.8-1.11.. I want to use particle effects for my plugin on 1.8-1.11 but it gives me this error on 1.9+

ERROR:

@mehboss
Packet names no longer require an id (such as the 63). The packet you are looking for should be PacketPlayOutWorldParticle

 

@Zombie_Striker

What do I change the IDs to? I don't get what you mean, where is an ID?

 

@mehboss
Packet63WorldParticles.

That packet no longer exists, it has been replaced with PacketPlayOutWorldParticle.

 

@Zombie_Striker

This is the line I have found:

Code:

                Class<?> packetClass = PackageType.MINECRAFT_SERVER.getClass(version < 7 ? "Packet63WorldParticles" : "PacketPlayOutWorldParticles");

It seems to already have both the ID and the playoutworld.

 

@mehboss
Can you print out what version is equal to?

 

@Zombie_Striker

The variable is set like this in the particleeffect lib:

Code:

                version = Integer.parseInt(Character.toString(PackageType.getServerVersion().charAt(3)));

I try to print it here:

Code:

        if (args[0].equalsIgnoreCase("/ban")) {
            e.setCancelled(true);
         
            Bukkit.broadcastMessage(String.valueOf(ParticleEffect.ParticlePacket.getVersion()));

It just gives me the version is incompatible error.

 

@mehboss
You current version is v1.11.
the char ar 3 is 1. So it's lower than 7 and you have your exception class not found.
check if the 4th char is a '_' or an int in addition.

 

@Caderape2 @Zombie_Striker

I think this is outdated too much, the place I got it from hasn't been updated since 2015. I want an API/Util that is 1.8.x-1.11x not just 1.8 that is used to spawn particles easily, with offset + color.. Any suggestions?

 

@mehboss
Try this:

Code:

private static final String SERVER_VERSION;
   
   
    static {
        String name = Bukkit.getServer().getClass().getName();
        name = name.substring(name.indexOf("craftbukkit.")
                + "craftbukkit.".length());
        name = name.substring(0, name.indexOf("."));
        SERVER_VERSION = name;
    }
    public static boolean isVersionHigherThan(int mainVersion,
            int secondVersion) {
        String firstChar = SERVER_VERSION.substring(1, 2);
        int fInt = Integer.parseInt(firstChar);
        if (fInt < mainVersion)
            return false;
        StringBuilder secondChar = new StringBuilder();
        for (int i = 3; i < 10; i++) {
            if (SERVER_VERSION.charAt(i) == '_'
                    || SERVER_VERSION.charAt(i) == '.')
                break;
            secondChar.append(SERVER_VERSION.charAt(i));
        }
        int sInt = Integer.parseInt(secondChar.toString());
        if (sInt < secondVersion)
            return false;
        return true;
    }

And you would use it by adding:

Code:

if(isVersionHigherThan(1,7)){
//If you are checking if it is 1.8 or higher. If this is false, then it is 1.7 or lower.

 

@Zombie_Striker

Where do I put this, under the constructor in the particle-effect lib?

 

@mehboss
Anywhere. Its a static method, so all you need to do is reference the class it is in to call the method. If you want, it can go in the particle effect lib.

 

@Zombie_Striker

How would this fix the problem if it goes anywhere? The particles aren't showing either & they were when I was using particle-effect lib on 1.8, it isn't just the error. I just assumed the particles weren't working because of the error.

 

Hey. I'm currently having the same exact problem. I see you marked this as solved, did you fix it? if so, would you mind sending me or posting the code you ended up using for the "PacketPlayOutWorldParticles" line of code

 

I just used playEffect instead, since it has offset and data values too.
