Hey, guys. I need some help with a problem. I tried adding a custom particle effect, but when i want to use it in game, the game crashes. Here is the crash report and the code:

 

 

package com.NeverMind.SonOfGods;

 

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import net.minecraft.client.Minecraft;

import net.minecraft.util.ResourceLocation;

import net.minecraft.world.World;

 

@SideOnly(Side.CLIENT)

public class EntityClothFX extends EntityFX {

 

private static final ResourceLocation texture = new ResourceLocation("Nevermind2:" + "textures/particle/particlecloth.png");

 

protected EntityClothFX(World par1World, double x, double y, double z) {

super(par1World, x, y, z);

setGravity(0);

}

public void renderParticle(Tessellator par1Tessellator, float par2, float par3, float par4, float par5, float par6, float par7)

{

float f6 = (float)this.particleTextureIndexX / 16.0F;

    float f7 = f6 + 0.0624375F;

    float f8 = (float)this.particleTextureIndexY / 16.0F;

    float f9 = f8 + 0.0624375F;

    float f10 = 0.1F * this.particleScale;

 

    if (this.particleIcon != null)

    {

        f6 = this.particleIcon.getMinU();

        f7 = this.particleIcon.getMaxU();

        f8 = this.particleIcon.getMinV();

        f9 = this.particleIcon.getMaxV();

    }

 

    float f11 = (float)(this.prevPosX + (this.posX - this.prevPosX) * (double)par2 - interpPosX);

    float f12 = (float)(this.prevPosY + (this.posY - this.prevPosY) * (double)par2 - interpPosY);

    float f13 = (float)(this.prevPosZ + (this.posZ - this.prevPosZ) * (double)par2 - interpPosZ);

    par1Tessellator.setColorRGBA_F(this.particleRed, this.particleGreen, this.particleBlue, this.particleAlpha);

    par1Tessellator.addVertexWithUV((double)(f11 - par3 * f10 - par6 * f10), (double)(f12 - par4 * f10), (double)(f13 - par5 * f10 - par7 * f10), (double)f7, (double)f9);

    par1Tessellator.addVertexWithUV((double)(f11 + par3 * f10 + par6 * f10), (double)(f12 + par4 * f10), (double)(f13 + par5 * f10 + par7 * f10), (double)f6, (double)f8);

    par1Tessellator.addVertexWithUV((double)(f11 + par3 * f10 - par6 * f10), (double)(f12 - par4 * f10), (double)(f13 + par5 * f10 - par7 * f10), (double)f6, (double)f9);

}

 

public int getFXLayer()

{

return 3;

}

 

public EntityClothFX setMaxAge(int maxAge){

particleMaxAge = maxAge;

return this;

}

 

public EntityClothFX setGravity(int gravity)

{

particleGravity = gravity;

return this;

}

 

public EntityClothFX setscale(int scale)

{

particleScale = scale;

return this;

}

 

 

//this is how I try to add it in the game

 

Minecraft.getMinecraft().effectRenderer.addEffect(new EntityClothFX(world, (double)x, (double)y, (double)z));

this is the line:  par3 = ((AxisAlignedBB)list.get(i)).calculateYOffset(this.boundingBox, par3);

 

I don't understand what works wrong.

I know this post is old, but the problem is still a thing.

I had the same issue. It's because Minecraft can only handle 4000 particles at once. If there are more than 4000, the game crashes.
