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:

And here is FusionBomb.class, which calls the first method to create the explosion:

public class FusionBomb extends Block implements IFusionObject {

public FusionBomb() {
	super(Material.tnt);
	setHarvestLevel(null, 0);
	setStepSound(Block.soundTypeMetal);
	setHardness(2F);
	setLightLevel(1F);
	setCreativeTab(Fusion.tabFusion);
	setUnlocalizedName(name);
}

@Override

	explode(w, p);
}

@Override
public IBlockState onBlockPlaced(World w, BlockPos p, EnumFacing f, float hitx, float hity, float hitz, int meta, EntityLivingBase e) {
	if (w.isBlockIndirectlyGettingPowered(p) > 0) {
		explode(w, p);
		w.notifyNeighborsOfStateChange(p, this);
	}
	return super.onBlockPlaced(w, p, f, hitx, hity, hitz, meta, e);
}

@Override
public void onNeighborBlockChange(World w, BlockPos p, IBlockState s, Block b) {
	if (w.isBlockIndirectlyGettingPowered(p) > 0) {
		explode(w, p);
		w.notifyNeighborsOfStateChange(p, this);
	}
}

public static void explode(World w, BlockPos p) {
	if(!w.isRemote)
		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);

}

@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"));
}
}

And yes, it is shown that I checked !World.isRemote before creating the explosion. I'm stumped, thanks in advance.

Hi

 

>And yes, it is shown that I checked !World.isRemote before creating the explosion. I'm stumped, thanks in advance.

ironic really :)    In this case the explosion needs to execute on both client and server. You can tell this if you put a breakpoint in the vanilla doExplosionB - it breaks twice, once on server thread, once on client thread.  Particle spawning does nothing on the server, which is why you don't see anything.

Hmmm that's curious

 

Try putting a breakpoint here

 

public void doExplosionB(boolean b) {

this.w.playSoundEffect(this.x, this.y, this.z, "random.explode", 4.0F, (1.0F + (this.w.rand.nextFloat() - this.w.rand.nextFloat()) * 0.2F) * 0.7F);

if ((this.size >= 2.0F) && (this.s))  // HERE

 

and seeing whether it calls triggered on both the client and the server threads.

Sorry dude, I'm out of ideas then.  You'll probably need to trace into the this.w.spawnParticle method to see what the problem is.  It might help to compare with a block of TNT detonated at the same location.

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.....
