Entity not spawning block on impact/replacing existing blocks [1.11.2] [Solved]

Recommended Posts

Basically when my entity hits a block it's supposed to place a flowing lava on top of existing blocks, however my entity currently replaces existing blocks with lava instead of on top, also it doesn't place lava every time it impacts a block,  can someone help.

 

Here is my code:

Fixed code for anyone who is having the same issue:

 

package top.mod.item;

 

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.monster.EntityBlaze;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.init.Blocks;

import net.minecraft.util.DamageSource;

import net.minecraft.util.EnumParticleTypes;

import net.minecraft.util.datafix.DataFixer;

import net.minecraft.util.math.BlockPos;

import net.minecraft.util.math.RayTraceResult;

import net.minecraft.world.World;

import net.minecraftforge.fml.relauncher.Side;

import net.minecraftforge.fml.relauncher.SideOnly;

 

public class EntityFirestaff extends EntityThrowable

{

    public EntityFirestaff(World worldIn)

    {

        super(worldIn);

    }

 

    public EntityFirestaff(World worldIn, EntityLivingBase throwerIn)

    {

        super(worldIn, throwerIn);

    }

 

    public EntityFirestaff(World worldIn, double x, double y, double z)

    {

        super(worldIn, x, y, z);

    }

 

    public static void registerFixesSnowball(DataFixer fixer)

    {

        EntityThrowable.registerFixesThrowable(fixer, "Snowball");

    }

 

    @SideOnly(Side.CLIENT)

    public void handleStatusUpdate(byte id)

    {

        if (id == 3)

        {

            for (int i = 0; i < 8; ++i)

            {

                this.world.spawnParticle(EnumParticleTypes.FLAME, this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D, new int[0]);

            }

        }

    }

 

    /**

    * Called when this EntityThrowable hits a block or entity.

    */

    protected void onImpact(RayTraceResult result)

    {

        if (result.entityHit != null)

        {

            int i = 0;

 

            if (result.entityHit instanceof EntityBlaze)

            {

                i = 3;

            }

 

            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), 41.0F);

           

        }

 

        if (!this.world.isRemote)

        {

            this.world.setEntityState(this, (byte)3);

            world.setBlockState(new BlockPos(this.posX, this.posY, this.posZ), Blocks.FLOWING_LAVA.getDefaultState(), 3);

            this.setDead();

        }

    }

}

Change:

if (true) {

To:

if(world.getBlockState(new BlockPos(this.posX, this.posY, this.posZ)).getMaterial() == Material.AIR) {

 

And you can create one blockpos for the if-statement and the next line (the setBlock) as well.  And maybe you'll want a loop that checks a range of blocks.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I think it might be better to use

Block#isReplaceable(...)

so you don't have to rely on the

Material

to be replaceable.

Don't PM me with questions. They will be ignored! Make a thread on the appropriate board for support.

1.7.10 and older versions of Minecraft are no longer supported due to it's age! Update to the latest version for support.

Through a bit of trial and error and using your help I managed to get the lava to spawn every time the projectile gits a block without replacing existing ones.

 

Here's my code if anyone else needs it:

 

package top.mod.item;

 

import net.minecraft.entity.EntityLivingBase;

import net.minecraft.entity.monster.EntityBlaze;

import net.minecraft.entity.projectile.EntityThrowable;

import net.minecraft.init.Blocks;

import net.minecraft.util.DamageSource;

import net.minecraft.util.EnumParticleTypes;

import net.minecraft.util.datafix.DataFixer;

import net.minecraft.util.math.BlockPos;

import net.minecraft.util.math.RayTraceResult;

import net.minecraft.world.World;

import net.minecraftforge.fml.relauncher.Side;

import net.minecraftforge.fml.relauncher.SideOnly;

 

public class EntityFirestaff extends EntityThrowable

{

    public EntityFirestaff(World worldIn)

    {

        super(worldIn);

    }

 

    public EntityFirestaff(World worldIn, EntityLivingBase throwerIn)

    {

        super(worldIn, throwerIn);

    }

 

    public EntityFirestaff(World worldIn, double x, double y, double z)

    {

        super(worldIn, x, y, z);

    }

 

    public static void registerFixesSnowball(DataFixer fixer)

    {

        EntityThrowable.registerFixesThrowable(fixer, "Snowball");

    }

 

    @SideOnly(Side.CLIENT)

    public void handleStatusUpdate(byte id)

    {

        if (id == 3)

        {

            for (int i = 0; i < 8; ++i)

            {

                this.world.spawnParticle(EnumParticleTypes.FLAME, this.posX, this.posY, this.posZ, 0.0D, 0.0D, 0.0D, new int[0]);

            }

        }

    }

 

    /**

    * Called when this EntityThrowable hits a block or entity.

    */

    protected void onImpact(RayTraceResult result)

    {

        if (result.entityHit != null)

        {

            int i = 0;

 

            if (result.entityHit instanceof EntityBlaze)

            {

                i = 3;

            }

 

            result.entityHit.attackEntityFrom(DamageSource.causeThrownDamage(this, this.getThrower()), 41.0F);

           

        }

 

        if (!this.world.isRemote)

        {

            this.world.setEntityState(this, (byte)3);

            world.setBlockState(new BlockPos(this.posX, this.posY, this.posZ), Blocks.FLOWING_LAVA.getDefaultState(), 3);

            this.setDead();

        }

    }

}
