Your instance annotation should have the modid inside, not the name

You can download all the mods you want using gradle : just use the dev version (de-obfuscated) or add the code chicken core (/code chicken lib) in your dev workspace to play with obfuscated mods without de-deobfuscating the mod, I've made a tutorial for this here : http://www.minecraftforgefrance.fr/showthread.php?tid=2689 (in french sorry) There is 3 types of jars : the obfuscated (the one used to play), the de-obfuscated (to use in your dev environment), the source (uncompiled files). the API seems to be only the files to use to make your classpath happy

Correction : it seems to work, before I tested it no particles appeared. EDIT : no particles appeared because I was using world.spawnParticle.

Before I used if (this.worldObj.isRemote) but no particles appeared. I think it's because the particles are entities, and entities need to be spawned from the server.

Recently I had to create a smoke grenade. In order to do this, I used particles but the problem was that the player could deactivate them in the options so I used another way to do it. All were fine during a time but after my game crashes with different crash reports : My class : (EntityGrenade.class) public void performAction(MovingObjectPosition mop) { switch (this.metadata) { case 1: if (this.fuse > 0) { for (int i = 0; i < 4; i++) { Minecraft mc = Minecraft.getMinecraft(); if (mc.renderViewEntity != null && mc.effectRenderer != null) { float multi = 1.6F; double x = this.posX + this.rand.nextGaussian() * multi; double y = this.posY + ((this.rand.nextDouble() - 0.2D) * 3) * multi; double z = this.posZ + this.rand.nextGaussian() * multi; double d = mc.renderViewEntity.posX - x; double d1 = mc.renderViewEntity.posY - y; double d2 = mc.renderViewEntity.posZ - z; if (d * d + d1 * d1 + d2 * d2 <= 1024.0D) mc.effectRenderer.addEffect(new EntitySmokeFX(this.worldObj, x, y, z, 0.0D, 0.0D, 0.0D, 2.0F)); // Particles are created here } } if (this.fuse >= 20) this.setDead(); } break; default: if (!this.worldObj.isRemote && this.fuse >= 40 || (mop != null && mop.entityHit != null)) { this.setDead(); this.worldObj.createExplosion(this, this.posX, this.posY + 1.0D, this.posZ, 3.4F, this.worldObj.getGameRules().getGameRuleBooleanValue("mobGriefing")); } break; } } The crash report is not always the same : the entity type change every time. Once it was an EntityItem and another time a particle. But the NPE is in these loops : List list = this.worldObj.getCollidingBoundingBoxes(this, this.boundingBox.addCoord(p_70091_1_, p_70091_3_, p_70091_5_)); for (int i = 0; i < list.size(); ++i) { p_70091_3_ = ((AxisAlignedBB)list.get(i)).calculateYOffset(this.boundingBox, p_70091_3_); // here (Entity.class:692) } this.boundingBox.offset(0.0D, p_70091_3_, 0.0D); if (!this.field_70135_K && d7 != p_70091_3_) { p_70091_5_ = 0.0D; p_70091_3_ = 0.0D; p_70091_1_ = 0.0D; } boolean flag1 = this.onGround || d7 != p_70091_3_ && d7 < 0.0D; int j; for (j = 0; j < list.size(); ++j) { p_70091_1_ = ((AxisAlignedBB)list.get(j)).calculateXOffset(this.boundingBox, p_70091_1_); // Or here (Entity.class:709) } this.boundingBox.offset(p_70091_1_, 0.0D, 0.0D); if (!this.field_70135_K && d6 != p_70091_1_) { p_70091_5_ = 0.0D; p_70091_3_ = 0.0D; p_70091_1_ = 0.0D; } for (j = 0; j < list.size(); ++j) { p_70091_5_ = ((AxisAlignedBB)list.get(j)).calculateZOffset(this.boundingBox, p_70091_5_); // Or here (Entity.class:723) } The only thing that can cause a NPE is the method "calculateYOffset" / "calculateXOffset" / "calculateZOffset". But when I see the code when the list comes from : public List getCollidingBoundingBoxes(Entity p_72945_1_, AxisAlignedBB p_72945_2_) { this.collidingBoundingBoxes.clear(); int i = MathHelper.floor_double(p_72945_2_.minX); int j = MathHelper.floor_double(p_72945_2_.maxX + 1.0D); int k = MathHelper.floor_double(p_72945_2_.minY); int l = MathHelper.floor_double(p_72945_2_.maxY + 1.0D); int i1 = MathHelper.floor_double(p_72945_2_.minZ); int j1 = MathHelper.floor_double(p_72945_2_.maxZ + 1.0D); for (int k1 = i; k1 < j; ++k1) { for (int l1 = i1; l1 < j1; ++l1) { if (this.blockExists(k1, 64, l1)) { for (int i2 = k - 1; i2 < l; ++i2) { Block block; if (k1 >= -30000000 && k1 < 30000000 && l1 >= -30000000 && l1 < 30000000) { block = this.getBlock(k1, i2, l1); } else { block = Blocks.stone; } block.addCollisionBoxesToList(this, k1, i2, l1, p_72945_2_, this.collidingBoundingBoxes, p_72945_1_); } } } } double d0 = 0.25D; List list = this.getEntitiesWithinAABBExcludingEntity(p_72945_1_, p_72945_2_.expand(d0, d0, d0)); for (int j2 = 0; j2 < list.size(); ++j2) { AxisAlignedBB axisalignedbb1 = ((Entity)list.get(j2)).getBoundingBox(); if (axisalignedbb1 != null && axisalignedbb1.intersectsWith(p_72945_2_)) // NullPointerCheck with "axisalignedbb1 != null" { this.collidingBoundingBoxes.add(axisalignedbb1); } axisalignedbb1 = p_72945_1_.getCollisionBox((Entity)list.get(j2)); if (axisalignedbb1 != null && axisalignedbb1.intersectsWith(p_72945_2_)) // Same here { this.collidingBoundingBoxes.add(axisalignedbb1); } } return this.collidingBoundingBoxes; } So it can't be the source of the crash. If you know why, tell me, it's been 4 days since I'm looking for an answer but it seems impossible for me. Forge version : tested in 1.7.10-10.13.4.1448 and 1.7.10-10.13.4.1481.

I can get it to work by implementing IEntityAdditionalSpawnData, but it takes a bit of time to update the y offset : After a bit of time :

I found out that the method onBlockAdded is fired only on the server, And when I spawn the entity, the client doesn't know that the entity is actually there : I will put the spawn of the mob in another method to see if there is a difference.

The name of the event is InitGuiEvent, but you can also use the postInitializationEvent

Minecraft.getMinecraft().thePlayer.getGameProfile()

You can replace the block with GameRegistry.addSubstitute (or something like that).

The break event gives you all the parameters you need to get the block metadata, new ItemStack(evt.block, 1, evt.blockMetadata)

File corruption with techne example : LegR = new ModelRenderer(this, 46, 0); LegR.addBox(0F, 0F, 0F, 4, 16, 4); // The variables names should begin with a lower case letter LegR.setRotationPoint(1F, 8F, -2F); LegR.setTextureSize(64, 64); LegR.mirror = true; // Miror texture should be after the initialization setRotation(LegR, 0F, 0F, 0F); The reason that your animation doesn't work is because your event is fired once, but the method setLivingAnimation is fired every render tick.

You are using a liquid material : super(Material.water); try with a correct Material.

I tested what you said, and I confirm : this is a bug. Another thing I found is that when you shift click, the event is fired 4 times but a simple click fires it 2 times (client and server I suppose).
