I want my sword item to spawn particles when it's right clicked. I'm not really sure how to do it, I was hoping someone could give me a sample. Heres the code I have for my sword:

package redstone;
import java.util.Random;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumToolMaterial;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemSword;
import net.minecraft.world.World;
public class RedstoneSword extends ItemSword
{
public RedstoneSword(int par1, EnumToolMaterial par2EnumToolMaterial)
{
super(par1, par2EnumToolMaterial);
}
@Override
public void updateIcons(IconRegister par1IconRegister) {
this.iconIndex = par1IconRegister.registerIcon("redstoneTextures:redstoneSword");
}
}

I tried to insert a spawnParticle on an item right click and I'm not quite sure what I'm doing wrong:

 

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{

	par2World.spawnParticle("reddust", par3EntityPlayer.posX, par3EntityPlayer.posY, par3EntityPlayer.posZ, 0.0D, 0.0D, 0.0D);


	par3EntityPlayer.setItemInUse(par1ItemStack, this.getMaxItemUseDuration(par1ItemStack));
	return par1ItemStack;
}

 

The last part with set Item in Use is just so the sword continues to block. It still does nothing, please help.

Are you sure? It looks like the particles are being spawned inside the player, with no velocity, so it may be that they're being spawned but you can't see them.

I'm almost positive. I tried making the particles spawn at places like 1 block in front of the player, but still nothing.

What if you change the velocity?

to me it seems like the correct way is being used.

I don't think that would make much of a difference, considering many of the vanilla particle effects don't integrate velocity whatsoever.

I finally got it to work! Here's the code for the whole class, I'm not quite sure how it was different but it works for some reason now:

package redstone;

import java.util.Random;

import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.EnumToolMaterial;
import net.minecraft.item.ItemStack;
import net.minecraft.item.ItemSword;
import net.minecraft.world.World;

public class RedstoneSword extends ItemSword
{
public RedstoneSword(int par1, EnumToolMaterial par2EnumToolMaterial)
{
	super(par1, par2EnumToolMaterial);
}

@Override
public void updateIcons(IconRegister par1IconRegister) {
	this.iconIndex = par1IconRegister.registerIcon("quartzTextures:quartzSword");
}

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
	for(int countparticles = 0; countparticles <= 10; ++countparticles)
	{
		par2World.spawnParticle("reddust", par3EntityPlayer.posX + 1, par3EntityPlayer.posY, par3EntityPlayer.posZ, 0.0D, 0.0D, 0.0D);
	}

	par3EntityPlayer.setItemInUse(par1ItemStack, this.getMaxItemUseDuration(par1ItemStack));
	return par1ItemStack;
}
}

 

But now I have a different problem. The particles only spawn in the same place, which is always 1 block east of the player, no matter where he is looking. I think having the same effect as the potions do would be appropriate. Does anyone know where that is?

EntityLiving.updatePotionEffects();

Thank you, it works just the way I wanted it to! Here's the final code or the spawning:

public ItemStack onItemRightClick(ItemStack par1ItemStack, World par2World, EntityPlayer par3EntityPlayer)
{
	Random rand = new Random();
	for(int countparticles = 0; countparticles <= 10; ++countparticles)
	{
		par2World.spawnParticle("reddust", par3EntityPlayer.posX + (rand.nextDouble() - 0.5D) * (double)par3EntityPlayer.width, par3EntityPlayer.posY + rand.nextDouble() * (double)par3EntityPlayer.height - (double)par3EntityPlayer.yOffset, par3EntityPlayer.posZ + (rand.nextDouble() - 0.5D) * (double)par3EntityPlayer.width, 0.0D, 0.0D, 0.0D);
	}

	par3EntityPlayer.setItemInUse(par1ItemStack, this.getMaxItemUseDuration(par1ItemStack));
	return par1ItemStack;
}
