[1.7.10] Spawning Particles on a block

[Whyneb360]

Hey everyone,

 

I am trying to make particles spawn at a block, and have done it before in a mod I no longer have, but I can't seem to replicate it. My code is as follows:

 

import java.util.Random;

import com.descon.mod.DesconCreativeTabs;
import com.descon.mod.Main;
import com.descon.tileentity.TileEntityCampFire;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.block.BlockContainer;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.tileentity.TileEntity;
import net.minecraft.world.World;

public class CampfireProp extends BlockContainer{

public CampfireProp(Material material) {
	super(material);

	this.setCreativeTab(DesconCreativeTabs.tabGeneral);
	this.setLightLevel(0.7F);
	this.setHarvestLevel("axe", 1);
	this.setHardness(1F);
	this.setBlockBounds(0F, 0F, 0F, 1F, 0.125F, 1F);
	this.setBlockTextureName(Main.modID + ":" + "textures/blocks/campfire.png");
}

 public void randomDisplayTick(World p_149734_1_, int p_149734_2_, int p_149734_3_, int p_149734_4_, Random p_149734_5_) {

	 float f = (float)p_149734_2_ + 0.5F;
         float f1 = (float)p_149734_3_ + 0.2F + p_149734_5_.nextFloat() * 3.0F / 8.0F;
         float f2 = (float)p_149734_4_ + 0.5F;
         float f3 = 0.0F;
         float f4 = p_149734_5_.nextFloat() * 0.0F - 0.0F;

	 p_149734_1_.spawnParticle("smoke", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         p_149734_1_.spawnParticle("flame", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         
         p_149734_1_.spawnParticle("smoke", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         p_149734_1_.spawnParticle("flame", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         
         p_149734_1_.spawnParticle("smoke", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         p_149734_1_.spawnParticle("flame", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         
         p_149734_1_.spawnParticle("smoke", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
         p_149734_1_.spawnParticle("flame", (double)(f - f3), (double)f1, (double)(f2 + f4), 0.0D, 0.0D, 0.0D);
 }


public int getRenderType() {
	return -1;
}

public boolean isOpaqueCube() {
	return false;
}

public boolean renderAsNormalBlock() {
	return false;
}

@Override
public TileEntity createNewTileEntity(World var1, int var2) {
	return new TileEntityCampFire();
}

@SideOnly(Side.CLIENT)
public void registerBlockIcons(IIconRegister iconRegister) {
	this.blockIcon = iconRegister.registerIcon(Main.modID + ":" + this.getUnlocalizedName().substring(5));
}

}

 

Do I need to reference it somewhere or add some extra code?

 

Any help would be appreciated,

You could have a look at the redstone ore class, thats what i used for my ores:

[Whyneb360]

Thanks for your reply, I just tried messing around with that, but found that it didn't help me - particles still aren't appearing

[The_SlayerMC]

Try putting an @Override over your display tick method. See if you're overriding it

[Whyneb360]

It had the green arrow next to it, indicating an Override, but I put one on top anyway - no difference. Thanks anyway though

[The_SlayerMC]

Well you can have a look at my ore class to see if it will help!

[Whyneb360]

As I am not fluent in Java, or particularly good at Modding (yet  , your class file doesn't help me much (also because you seem to be doing something more complicated than I am). I did manage to dig up my old mod - the on the worked with block particles, and launch it with the latest forge, but it doesn't work any more. Is there a new way to do particle effects?

[The_SlayerMC]

Not really... And there is nothing "special" to what my ores are doing really... Aha

[Whyneb360]

I see... Hmm... If you were to make just a super basic block emit particle effects, how would you go about doing it?

[The_SlayerMC]

well you can have a look at "EntityReddustFX.java" and do magic by c&p that, then add this into your block.java:

@Override
@SideOnly(Side.CLIENT)
public void randomDisplayTick(World w, int x, int y, int z, Random rand) {
	renderParticle(w, x, y, z);
}

private void renderParticle(World w, int x, int y, int z) {
	Random random = w.rand;
	double d0 = 0.0625D;
	for(int l = 0; l < 6; ++l) {
		double d1 = (double)((float)x + random.nextFloat());
		double d2 = (double)((float)y + random.nextFloat());
		double d3 = (double)((float)z + random.nextFloat());
		if(l == 0 && !w.getBlock(x, y + 1, z).isOpaqueCube()) d2 = (double)(y + 1) + d0;
		if(l == 1 && !w.getBlock(x, y - 1, z).isOpaqueCube()) d2 = (double)(y + 0) - d0;
		if(l == 2 && !w.getBlock(x, y, z + 1).isOpaqueCube()) d3 = (double)(z + 1) + d0;    
		if(l == 3 && !w.getBlock(x, y, z - 1).isOpaqueCube()) d3 = (double)(z + 0) - d0;
		if(l == 4 && !w.getBlock(x + 1, y, z).isOpaqueCube()) d1 = (double)(x + 1) + d0;
		if(l == 5 && !w.getBlock(x - 1, y, z).isOpaqueCube()) d1 = (double)(x + 0) - d0;
		if(d1 < (double)x || d1 > (double)(x + 1) || d2 < 0.0D || d2 > (double)(y + 1) || d3 < (double)z || d3 > (double)(z + 1)) {
			OreParticleFX fx= new OreParticleFX(w, d1, d2, d3);
			FMLClientHandler.instance().getClient().effectRenderer.addEffect(fx);
		}
	}
}

And thats basically it

[Whyneb360]

What would I replace "OreParticleFX" with? Do I have to create a new class and put a flame effect in there? How would I reference that? Sorry for the rapid-fire questions

[The_SlayerMC]

If you want to use a vanilla particle, such as the flame:

world.spawnParticle("flame", x, y, z, 0.0D, 0.0D, 0.0D);

[Whyneb360]

So, this is what I have now:

 

@Override
@SideOnly(Side.CLIENT)
public void randomDisplayTick(World w, int x, int y, int z, Random rand) {
	renderParticle(w, x, y, z, w);
}

private void renderParticle(World w, int x, int y, int z, World world) {
	Random random = w.rand;
	double d0 = 0.0625D;
	for(int l = 0; l < 6; ++l) {
		double d1 = (double)((float)x + random.nextFloat());
		double d2 = (double)((float)y + random.nextFloat());
		double d3 = (double)((float)z + random.nextFloat());
		if(l == 0 && !w.getBlock(x, y + 1, z).isOpaqueCube()) d2 = (double)(y + 1) + d0;
		if(l == 1 && !w.getBlock(x, y - 1, z).isOpaqueCube()) d2 = (double)(y + 0) - d0;
		if(l == 2 && !w.getBlock(x, y, z + 1).isOpaqueCube()) d3 = (double)(z + 1) + d0;    
		if(l == 3 && !w.getBlock(x, y, z - 1).isOpaqueCube()) d3 = (double)(z + 0) - d0;
		if(l == 4 && !w.getBlock(x + 1, y, z).isOpaqueCube()) d1 = (double)(x + 1) + d0;
		if(l == 5 && !w.getBlock(x - 1, y, z).isOpaqueCube()) d1 = (double)(x + 0) - d0;
		if(d1 < (double)x || d1 > (double)(x + 1) || d2 < 0.0D || d2 > (double)(y + 1) || d3 < (double)z || d3 > (double)(z + 1)) {
			world.spawnParticle("flame", x, y, z, 0.0D, 0.0D, 0.0D);
		}
	}
}

 

This doesn't work, and I know I've done something wrong, but I just can't crack it. Thanks for all of your help so far though - much appreciated
