DonkeyCore

That's okay. Your help was wonderful nonetheless. In other words, I'm slightly closer to figuring out the problem. In this class: package donkeycore.fusion.blocks; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraft.block.state.IBlockState; import net.minecraft.client.Minecraft; import net.minecraft.client.resources.model.ModelResourceLocation; import net.minecraft.entity.EntityLivingBase; import net.minecraft.init.Blocks; import net.minecraft.init.Items; import net.minecraft.item.ItemStack; import net.minecraft.util.BlockPos; import net.minecraft.util.EnumFacing; import net.minecraft.world.Explosion; import net.minecraft.world.World; import net.minecraftforge.fml.common.registry.GameRegistry; import net.minecraftforge.fml.relauncher.Side; import donkeycore.fusion.Fusion; import donkeycore.fusion.IFusionObject; public class FusionBomb extends Block implements IFusionObject { public static final String name = "fusion_bomb"; public FusionBomb() { super(Material.tnt); setHarvestLevel(null, 0); setStepSound(Block.soundTypeMetal); setHardness(2F); setLightLevel(1F); setCreativeTab(Fusion.tabFusion); setUnlocalizedName(name); } @Override public void onBlockDestroyedByExplosion(World w, BlockPos p, Explosion e) { explode(w, p); } @Override public IBlockState onBlockPlaced(World w, BlockPos p, EnumFacing f, float hitx, float hity, float hitz, int meta, EntityLivingBase e) { Fusion.info(w.getClass().getSimpleName()); if (w.isBlockIndirectlyGettingPowered(p) > 0) { Fusion.info("Passing: " + w.getClass().getSimpleName()); explode(w, p); w.notifyNeighborsOfStateChange(p, this); return Blocks.air.getDefaultState(); } return super.onBlockPlaced(w, p, f, hitx, hity, hitz, meta, e); } @Override public void onNeighborBlockChange(World w, BlockPos p, IBlockState s, Block b) { Fusion.info(w.getClass().getSimpleName()); if (w.isBlockIndirectlyGettingPowered(p) > 0) { Fusion.info("Passing: " + w.getClass().getSimpleName()); explode(w, p); w.notifyNeighborsOfStateChange(p, this); } } public static void explode(World w, BlockPos p) { Fusion.createFusionExplosion(w, p.getX(), p.getY(), p.getZ(), 6F, true, true, true); } @Override public void preinit() { GameRegistry.registerBlock(this, name); GameRegistry.addShapedRecipe(new ItemStack(this), "RAR", "FTF", "RAR", 'F', Fusion.getItemFromId("fusion_ingot"), 'A', Fusion.getItemFromId("active_fusion_ingot"), 'T', Blocks.tnt, 'R', Items.redstone); GameRegistry.addShapedRecipe(new ItemStack(this), "RFR", "ATA", "RFR", 'F', Fusion.getItemFromId("fusion_ingot"), 'A', Fusion.getItemFromId("active_fusion_ingot"), 'T', Blocks.tnt, 'R', Items.redstone); } @Override public void init() { if (Fusion.SIDE == Side.CLIENT) Minecraft.getMinecraft().getRenderItem().getItemModelMesher().register(GameRegistry.findItem(Fusion.MODID, name), 0, new ModelResourceLocation(Fusion.MODID + ":" + name, "inventory")); } } You can see I have a couple methods that call explode(). I have 2 of them set to tell me what world was being passed in. In onBlockPlaced, I noticed that it says: [09:18:24] [Client thread/INFO] [FML]: [Fusion] WorldClient [09:18:24] [Client thread/INFO] [FML]: [Fusion] Passing: WorldClient [09:18:24] [server thread/INFO] [FML]: [Fusion] WorldServer [09:18:24] [server thread/INFO] [FML]: [Fusion] Passing: WorldServer If I place a redstone torch THEN my custom block, it works perfectly and the explosion particles are clearly visible! However, you can see onNeighborBlockChange which displays: [09:18:59] [Client thread/INFO] [FML]: [Fusion] WorldClient [09:18:59] [server thread/INFO] [FML]: [Fusion] WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] Passing: WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] Passing: WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] WorldServer [09:19:00] [server thread/INFO] [FML]: [Fusion] WorldServer Which clearly does not seem to work properly. Only WorldServer is getting passed in for some reason, but the calls that the method makes is nearly identical to that of onBlockPlaced... hmm.....

Yep, it is definitely being called both times. Still no particles though unfortunately.

Thanks for replying! I removed the !w.isRemote check, and I can hear the sound, but I still don't see any explosion particles.

Sorry for posting again so soon, but I have another problem. I have a bomb block that causes an explosion based on redstone signals / time settings. It works fine, but the explosion particles (EXPLOSION_LARGE / EXPLOSION_HUGE) do not appear. I have a subclass of explosion that I'm using, but it works virtually the same way. Here is the method used to summon the explosion: public static final FusionExplosion createFusionExplosion(World w, double x, double y, double z, float size, boolean fire, boolean smoke, boolean strong) { FusionExplosion explosion = new FusionExplosion(w, null, x, y, z, size, fire, smoke, strong); if (ForgeEventFactory.onExplosionStart(w, explosion)) return explosion; explosion.doExplosionA(); explosion.doExplosionB(true); return explosion; } Here is FusionExplosion.class: package donkeycore.fusion; import java.util.HashSet; import java.util.Iterator; import java.util.List; import java.util.Map; import java.util.Random; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraft.block.state.IBlockState; import net.minecraft.enchantment.EnchantmentProtection; import net.minecraft.entity.Entity; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.util.AxisAlignedBB; import net.minecraft.util.BlockPos; import net.minecraft.util.EnumParticleTypes; import net.minecraft.util.MathHelper; import net.minecraft.util.Vec3; import net.minecraft.world.Explosion; import net.minecraft.world.World; import net.minecraftforge.event.ForgeEventFactory; import com.google.common.collect.Maps; import com.google.common.collect.Sets; public class FusionExplosion extends Explosion { private final boolean f; private final boolean s; private final Random r; private final World w; private final double x; private final double y; private final double z; private final Entity e; private final float size; private final List<Object> blocks; private final Map<Object, Object> map; private final boolean strong; public FusionExplosion(World w, Entity e, double x, double y, double z, float size, List<Object> l) { this(w, e, x, y, z, size, false, true, l); } public FusionExplosion(World w, Entity e, double x, double y, double z, float size, boolean f, boolean s, List<Object> l) { this(w, e, x, y, z, size, f, s, false); blocks.addAll(l); } public FusionExplosion(World w, Entity e, double x, double y, double z, float size, boolean f, boolean s, boolean strong) { super(w, e, x, y, z, size, f, s); this.r = new Random(); this.blocks = com.google.common.collect.Lists.newArrayList(); this.map = Maps.newHashMap(); this.w = w; this.e = e; this.size = size; this.x = x; this.y = y; this.z = z; this.f = f; this.s = s; this.strong = strong; } @SuppressWarnings({"unchecked", "rawtypes"}) public void doExplosionA() { HashSet<Object> hashset = Sets.newHashSet(); for(int i = 0; i < 16; i++) { for(int j = 0; j < 16; j++) { for(int k = 0; k < 16; k++) { if ((i == 0) || (i == 15) || (j == 0) || (j == 15) || (k == 0) || (k == 15)) { double d0 = i / 15.0F * 2.0F - 1.0F; double d1 = j / 15.0F * 2.0F - 1.0F; double d2 = k / 15.0F * 2.0F - 1.0F; double d3 = Math.sqrt(d0 * d0 + d1 * d1 + d2 * d2); d0 /= d3; d1 /= d3; d2 /= d3; float f = this.size * (0.7F + this.w.rand.nextFloat() * 0.6F); double d4 = this.x; double d6 = this.y; double d8 = this.z; for(; f > 0.0F; f -= 0.22500001F) { BlockPos blockpos = new BlockPos(d4, d6, d8); IBlockState iblockstate = this.w.getBlockState(blockpos); if (iblockstate.getBlock().getMaterial() != Material.air) { float f2 = this.e != null ? this.e.getExplosionResistance(this, this.w, blockpos, iblockstate) : iblockstate.getBlock().getExplosionResistance(this.w, blockpos, (Entity) null, this); f -= (f2 + 0.3F) * 0.3F; } if ((f > 0.0F) && ((this.e == null) || (this.e.func_174816_a(this, this.w, blockpos, iblockstate, f)))) { hashset.add(blockpos); } d4 += d0 * 0.30000001192092896D; d6 += d1 * 0.30000001192092896D; d8 += d2 * 0.30000001192092896D; } } } } } this.blocks.addAll(hashset); float f3 = this.size * 2.0F; int j = MathHelper.floor_double(this.x - f3 - 1.0D); int k = MathHelper.floor_double(this.x + f3 + 1.0D); int j1 = MathHelper.floor_double(this.y - f3 - 1.0D); int l = MathHelper.floor_double(this.y + f3 + 1.0D); int k1 = MathHelper.floor_double(this.z - f3 - 1.0D); int i1 = MathHelper.floor_double(this.z + f3 + 1.0D); List list = this.w.getEntitiesWithinAABBExcludingEntity(this.e, new AxisAlignedBB(j, j1, k1, k, l, i1)); ForgeEventFactory.onExplosionDetonate(this.w, this, list, f3); Vec3 vec3 = new Vec3(this.x, this.y, this.z); for(int l1 = 0; l1 < list.size(); l1++) { Entity entity = (Entity) list.get(l1); if (!entity.func_180427_aV()) { double d12 = entity.getDistance(this.x, this.y, this.z) / f3; if (d12 <= 1.0D) { double d5 = entity.posX - this.x; double d7 = entity.posY + entity.getEyeHeight() - this.y; double d9 = entity.posZ - this.z; double d13 = MathHelper.sqrt_double(d5 * d5 + d7 * d7 + d9 * d9); if (d13 != 0.0D) { d5 /= d13; d7 /= d13; d9 /= d13; double d14 = this.w.getBlockDensity(vec3, entity.getEntityBoundingBox()); double d10 = (1.0D - d12) * d14; entity.attackEntityFrom((strong ?

I'm stumped, thanks in advance. Edit: Added [1.8] prefix

Fair enough, I was aiming for neither prettiness nor fluency when coding that lol

Thank you all for helping! diesieben07 had the answer I needed, but you guys are all awesome for helping And yeah, the item registering code is temporary just so I could experiment with the concept... I'm not really big on reflection and I don't do it much, what was a major problem with the way I did it?

So should I fix this by putting that in its own separate method and calling the method for each package I want in order? Thanks, I'll try this!

I'm using 1.8 Forge and when registering my items/blocks, it appears crazily in the creative inventory. I know it sorts by item IDs, but I don't know how to register the blocks/items in the way I want so the IDs are sorted correctly.
