    I saw another thread for this, but imho, it was no the best, here's better formatted class.

    Code:

    Enjoy chumps, and happy coding.

    Thanks :D there's going to be tons of crazy crap you can do with these :p

    microgeek found a typo (I think): your HAPPY_VILLAGER should be "happyVillager".

    Love that effect

    Mine wasn't supposed to be a library just a simple look you can do it like this kind of thing

    My bad, I wrote those Strings at 6am, thanks for the heads up!

    What with tilecrack and itemcrack? Maybe add static method like sendToPlayerItemcrack and sendToPlayerTileCrack. Another thing is I confirmed for now only for 2 particles that speed is actually color. And I think you could name your enum more user-friendly. Like instead of RED_DUST something like REDSTONE_PARTICLES. Also what if someone wants to show particles to all players? He will do for loop which will execute your method. This way plugin like that would create a lot of the same packets. I already created API for that but it would be third API here so I won't publish it. But nice idea for method sendToPlayer in enum. I'm definetly stealing this idea :p

    EDIT:Since when there is 'Grum' instead of 'Tahg' next to reply and like button? :D

    Since I released it, I've added two more methods, sendParticleToPlayers(List<Player>) and sendParticleToLocation(Location), I'll update it later today.

    Dang, this is cool :3

    If only this would not restrict users to use MC 1.5 :( and I would use it right now :'(

    With those colours (the speed value on some effects), what values have you used? I've been able to get the standard colour and a rainbow, but nothing in between...:\

    Haven't tested it. I only noticed this:
    Code:
                        else if (par1Str.equals("mobSpell"))
                        {
                            var21 = new EntitySpellParticleFX(this.theWorld, par2, par4, par6, 0.0D, 0.0D, 0.0D);
                            ((EntityFX)var21).setRBGColorF((float)par8, (float)par10, (float)par12);
                        }
                        else if (par1Str.equals("mobSpellAmbient"))
                        {
                            var21 = new EntitySpellParticleFX(this.theWorld, par2, par4, par6, 0.0D, 0.0D, 0.0D);
                            ((EntityFX)var21).setAlphaF(0.15F);
                            ((EntityFX)var21).setRBGColorF((float)par8, (float)par10, (float)par12);
                        }
    Where par8, par10 and par12 are:
    Code:
                double var9 = this.rand.nextGaussian() * (double)par1Packet63WorldParticles.func_98197_l();
                double var11 = this.rand.nextGaussian() * (double)par1Packet63WorldParticles.func_98197_l();
                double var13 = this.rand.nextGaussian() * (double)par1Packet63WorldParticles.func_98197_l();
    And this method from packet returns speed.

    Hmmm. I'll keep trying. There must be something that does it...

    microgeek Just a tip: You could use reflection to get the Packet63WorldParticles and the .sendPacket so your api would be update-proof. I already did that by myself, you can message me if you want the code ;)

    I did that here as well :). It's not too hard if you have got the hang of reflection.

    Code:java
    1.  
    2. Method getHandle = p.getClass().getMethod("getHandle");
    3. Object nmsPlayer = getHandle.invoke(p);
    4. Field con_field = nmsPlayer.getClass().getField("playerConnection");
    5. Object con = con_field.get(nmsPlayer);
    6. Method packet_method = ReflectionUtil.getMethod(con.getClass(), "sendPacket");
    7. packet_method.invoke(con, packet);

    _DSH105_ Yeah, but you should get the packet through reflection too, because packets are only in the nms package^^

    2.  
    3. Object packet = Class.forName("net.minecraft.server" + v + ".Packet63WorldParticles").getConstructor().newInstance();

    Where have you added this code to? :eek:

    It hasn't been changed at all (not even "happerVillager" has been fixed yet).

    microgeek - Your thread needs updating.

    Ah okay, I thought maybe I missed something. Thanks. I'm guessing the theoretical "play at location" method is a lot better than just sending the packet to all players?

    How did you make this update-proof? Im trying to figure out java reflection but I can't seem to get it...

    It just takes a bit of practice and time to get the correct methods needed. It helps sometimes if you write it version-dependent first and then convert it.

    DarkBladee12 - that looks cool :) Mind if I use it?

    Also, is there anywhere that documents the effect of speed (does this just make the effect play faster?) & offset (just a standard location offset?) on the effects or just trial and error?

    Does the normal sendToLocation method provided by Bukkit actually send the particle to all players, or does it send it to players within a certain bound? It's probably more efficient to do the latter if that's how Bukkit handles it.

    Wow nice! I had figured it out after half an hour of fiddling and testing

    Zarius You can use it any time you want ;) The speed makes some particle effects play faster, but not all are affected by the speed! I always use "new Random().nextFloat()" for the offset values in order to let it look natural.

    ohtwo The sendToLocation method in my version just sends the particle effect to all players.
