Hi,

 

I want to make a block through which entities can move, but for some reason it's not working like I expected it to be.

So I can move into the block, but the block immediately pushes me out again on the same side.

 

 

import java.util.List;
import java.util.Random;

import net.minecraft.block.SoundType;
import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockState;
import net.minecraft.entity.EntityLiving.SpawnPlacementType;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.BlockRenderLayer;
import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.RayTraceResult;
import net.minecraft.world.Explosion;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;

public class BlockStructure extends Block {

public BlockStructure() {
	super(Material.BARRIER);

	this.setBlockUnbreakable();
	this.setResistance(5000000.f);
	this.setSoundType(SoundType.STONE);
}

    @Override
    public boolean isPassable(IBlockAccess worldIn, BlockPos pos) {
        return true;
    }

@Override
public BlockRenderLayer getBlockLayer() {
	return BlockRenderLayer.CUTOUT_MIPPED;
}

@Override
public boolean isFullBlock(IBlockState state) {
	return false;
}

/*@Override
public int getLightOpacity(IBlockState state, IBlockAccess world, BlockPos pos) {
	return 0;
}*/

    @Override
    public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos) {
        // return null, we don't want a collision detection for our leaves
        return NULL_AABB;
    }

/*@Override
public boolean isReplaceable(IBlockAccess worldIn, BlockPos pos) {
	return false;
}

@Override
public boolean isOpaqueCube(IBlockState state) {
	return false;
}

@Override
public boolean isVisuallyOpaque() {
	return false;
}

@Override
public boolean canSpawnInBlock() {
	return false;
}

@Override
public boolean requiresUpdates() {
	return false;
}

@Override
public boolean canDropFromExplosion(Explosion explosionIn) {
	return false;
}

@Override
public boolean canCreatureSpawn(IBlockState state, IBlockAccess world, BlockPos pos, SpawnPlacementType type) {
	return false;
}

@Override
public void onBlockDestroyedByExplosion(World worldIn, BlockPos pos, Explosion explosionIn) {
	worldIn.setBlockState(pos, this.getDefaultState());
}

@Override
public Item getItemDropped(IBlockState state, Random rand, int fortune) {
	return null;
}

@Override
public ItemStack getPickBlock(IBlockState state, RayTraceResult target, World world, BlockPos pos, EntityPlayer player) {
	return null;
}

@Override
public void addInformation(ItemStack stack, EntityPlayer player, List<String> tooltip, boolean advanced) {
	tooltip.add("This block will be replaced in structures.");

	if(advanced)
		tooltip.add("Only available through command!");
}*/
}

 

 

Any ideas?

 

Thx in advance.

You need to override

addCollisionBoxToList

and do nothing in it.

Vanilla example: BlockEndPortal;

public void addCollisionBoxToList(IBlockState state, World worldIn, BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, @Nullable Entity entityIn)
{
}

 

Does still not work.

Show what you have.

public class BlockStructure extends Block {

public BlockStructure() {
	super(Material.BARRIER);

	this.setBlockUnbreakable();
	this.setResistance(5000000.f);
	this.setSoundType(SoundType.STONE);
}


@Override
public BlockRenderLayer getBlockLayer() {
	return BlockRenderLayer.CUTOUT_MIPPED;
}

/*@Override
public boolean isFullBlock(IBlockState state) {
	return false;
}*/

/*@Override
public int getLightOpacity(IBlockState state, IBlockAccess world, BlockPos pos) {
	return 0;
}*/

@Override
public void addCollisionBoxToList(IBlockState state, World worldIn, BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, Entity entityIn) {
}

    @Override
    public AxisAlignedBB getCollisionBoundingBox(IBlockState blockState, World worldIn, BlockPos pos) {
        // return null, we don't want a collision detection for our leaves
        return NULL_AABB;
    }

@Override
public boolean isOpaqueCube(IBlockState state) {
	return false;
}

@Override
public boolean isVisuallyOpaque() {
	return false;
}
}

 

It also seems to be that the auto-jump does not work for my block, but I still can't move through it.

Try removing the getCollisionBoundingBox method, and only have addCollisionBoxToList.

This does also not work. Still not able to walk through the block.

You should override geCollisionBoundingBox to return null and isOpaqueBlock(IBlockState) and isFullCube(IBlockState) to both return false.

Does also not work.

Instead of isFullCube(IBlockState) you could try isFullBlock(IBlockState), isNormalBlock(IBlockState) or isNormalCube(IBlockState). One of those methods leads to the intended behaviour.

Hm, it seems to has something to do with the material. If I change the material to leaves it somehow works, but this is not what I want.

 

The barrier material seems not to let me move in, the leaves material throws shadows and the air material does not work with my custom blocks.

Create your own custom Material then one that will allow you and give you what you want.

Just how to make a material which is solid, but you can move through it and it has something like air, that no shadows are thrown.

I have no idea how to create such a material, even after looking into the Material class.

Sadly i do not have any code available at the moment (school) so i would keep messing around with it until some makes a suggestion.

isFullBlock(IBlockState)

 

The default implementation of isFullBlock checks

this.blockMaterial.isPassable()

, so yes, that would have an effect.
