I tried to make a similar block like the soulsand but the slow effect would be even slower.

 

Well the problem is it wont go any slower. I tried entityIn.motionZ *= 0.1D/0.3D/0.6D; but it is still same speed as the soulsand.

 

Is there some sort of limit to slow(i think it that there wont be one).

import net.minecraft.block.state.IBlockState;

import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;

public class BlockJungleMud extends Block {

protected static final AxisAlignedBB TAR_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.0D, 1.0D, 0.75D, 1.0D);

public BlockJungleMud() {
	super(Material.GROUND);
	this.setHardness(0.6F);
	this.setUnlocalizedName("jungle_mud");
	this.setRegistryName("jungle_mud");
	this.setSoundType(SoundType.GROUND);
}

@Nullable
public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos) {
	return TAR_AABB;
}

@Override
public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn) {
	entityIn.motionX *= 0.1D;
	entityIn.motionZ *= 0.1D;
}
}

onEntityCollidedWithBlock is called when a entity is inside of the collision box, so if your block is not smaller that the collision box there is no normal way for any Entity to "collide" with it.

It is smaller: new AxisAlignedBB(0.0D, 0.0D, 0.0D, 1.0D, 0.75D, 1.0D);

 

 

Web ad soul sand do different things. check how isInWeb is used in the Entity class. Maybe that will work better for you.

 

It is the soulsand code.

You got it the wrong way around.

The BB from getCollisionBoundinBox has to be bigger than the one from getBoundingBox. Either make the block return a BB with a smaller y-max in getBoundingBox, or make your collision BB have a y-max > 1.0.

 

Can't get the actual block-registration of the SoulSand block atm, but I believe it has a max-y set to ~0.85, which is less than what the collisionBB returns (0.875)

Soulsand code, which works like shown.

public class BlockSoulSand extends Block
{
    protected static final AxisAlignedBB SOUL_SAND_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.0D, 1.0D, 0.875D, 1.0D);

    public BlockSoulSand()
    {
        super(Material.SAND, MapColor.BROWN);
        this.setCreativeTab(CreativeTabs.BUILDING_BLOCKS);
    }

    @Nullable
    public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos)
    {
        return SOUL_SAND_AABB;
    }

    /**
     * Called When an Entity Collided with the Block
     */
    public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn)
    {
        entityIn.motionX *= 0.4D;
        entityIn.motionZ *= 0.4D;
    }
}

I've already reverted my change yesterday which changed exactly nothing. I can't make it slower nor faster.

 

There isn't much more of soulsand in the mc code or the jsons. That's the code and nothing more is changed.

 

registerBlock(88, "soul_sand", (new BlockSoulSand()).setHardness(0.5F).setSoundType(SoundType.SAND).setUnlocalizedName("hellsand"));

package net.minecraft.block;

import javax.annotation.Nullable;
import net.minecraft.block.material.MapColor;
import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockState;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.entity.Entity;
import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;

public class BlockSoulSand extends Block
{
    protected static final AxisAlignedBB SOUL_SAND_AABB = new AxisAlignedBB(0.0D, 0.0D, 0.0D, 1.0D, 0.875D, 1.0D);

    public BlockSoulSand()
    {
        super(Material.SAND, MapColor.BROWN);
        this.setCreativeTab(CreativeTabs.BUILDING_BLOCKS);
    }

    @Nullable
    public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos)
    {
        return SOUL_SAND_AABB;
    }

    /**
     * Called When an Entity Collided with the Block
     */
    public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entityIn)
    {
        entityIn.motionX *= 0.4D;
        entityIn.motionZ *= 0.4D;
    }
}

This is basically wrong.  For onCollide to work, the block needs to be smaller than a full cube, that's it.

 

I don't know why his code isn't working though.

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'm not sure why your code doesn't work, but I suspect that there is a Math.min call (or the if statement equivalent) somewhere after where Block#onEntityCollidedWithBlock is called. Not sure tho. However, I know for a fact you can move slower on a block because slimes cause the player to move super slowly when not bouncing. Perhaps you should check out BlockSlime to see how it's done there? I believe the motion changes are done in Block#onEntityWalk there instead of Block#onEntityCollidedWithBlock so that might have something to do with it
