[1.6.4] Spawning a Block at the Player's Feet [Solved]

Recommended Posts

Hello, I am creating a custom potion effect that spawns a custom air block at the player's feet. The custom block acts exactly like air(transparent texture, no collisions, etc.) but it outputs a redstone signal and I have that whole part working. The problem is that I can't get the block to spawn in the same block as the player's feet. It always spawns diagonally to the right.

 

Does anyone know how to use setBlock to set my custom block at the player's feet?

 

Here is my custom potion effect class:

 

 

package eclipse.MoreApples.potion;

import eclipse.MoreApples.common.MoreApples;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.potion.PotionEffect;

public class RedstonePotionEffect extends PotionEffect{

private boolean shouldCheck;
private double oldX;
private double oldY;
private double oldZ;

public RedstonePotionEffect(int par1, int par2) {
	super(par1, par2);
	shouldCheck = true;
}

@Override
public boolean onUpdate(EntityLivingBase p)
{
	EntityPlayer player = (EntityPlayer) p;
	if(shouldCheck)
	{
		/*
		 *This boolean 'shouldCheck' is just used to run this 
		 *segment of code once in order to set the original coordinates
		 *of the player
		 */
		oldX = p.posX;
		oldY = p.posY;
		oldZ = p.posZ;
		shouldCheck = false;
	}
	else if(duration <= 1)
	{
		shouldCheck = true;
	}

	if(p.posX != oldX || p.posY != oldY || p.posZ != oldZ || duration <= 1)
	{
		/*
		 * This segment of code replaces the old block that the player was at to air
		 * Since the player can only walk through air, I always set the blockID to 0
		 * I might add a way to check if the player was in water and set the block to water
		 * But that is not my top priority now =)
		 */

		player.addChatMessage("Should replace old block");
		p.worldObj.setBlock((int)oldX,(int) (oldY+player.yOffset),(int) oldZ, 0);
		oldX = p.posX;
		oldY = p.posY;
		oldZ = p.posZ;
	}
	if(duration > 1)
	p.worldObj.setBlock((int)p.posX, (int)(p.posY+player.yOffset), (int)p.posZ, MoreApples.customRedstoneAir.blockID);
	return super.onUpdate(p);
}



}

 

 

And here is my custom air block class

 

 

package eclipse.MoreApples.block;

import java.util.Random;

import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.util.AxisAlignedBB;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;
import net.minecraftforge.common.ForgeDirection;

public class BlockCustomRedstone extends Block{

public BlockCustomRedstone(int par1, Material par2Material) {
	super(par1, par2Material);
	// TODO Auto-generated constructor stub
}
@Override
 public boolean isAirBlock(World world, int x, int y, int z)
   {
        return true;
   }

 @Override
 public int isProvidingWeakPower(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)
    {
        return 15;
    }

@Override
    public void updateTick(World world, int i, int j, int k, Random random)
    {
        world.setBlockToAir(i, j, k);
    }
@Override
    public int tickRate(World world)
    {
        return 1;
    }
@Override
    public int isProvidingStrongPower(IBlockAccess par1IBlockAccess, int par2, int par3, int par4, int par5)
    {
        return 15;
    }
@Override
    public boolean isBlockSolidOnSide(World world, int x, int y, int z, ForgeDirection side)
    {
        return false;
    }
@Override
    public boolean isCollidable()
    {
        return false;
    }
@Override
    public boolean isOpaqueCube()
    {
        return false;
    }
@Override
    public void breakBlock(World world, int i, int j, int k, int par5, int par6)
    {
		world.notifyBlocksOfNeighborChange(i, j, k, this.blockID);
    }
@Override
    public boolean canProvidePower()
    {
        return true;
    }
@Override
public AxisAlignedBB getCollisionBoundingBoxFromPool(World par1World, int par2, int par3, int par4)
    {
	return null;
    }

@SideOnly(Side.CLIENT)

public void registerIcons(IconRegister register){
	/*
	 * I have not set the texture for this block so
	 * it renders as the default purple and black checkered square
	 * I do know that I have to specify the render pass by overwriting
	 * a method and creating a texture with alpha transparency
	 * but I want to use the purple and black checkered square
	 * for debugging purposes
	 */
}



}

 

 

Thanks for taking the time to help a fellow modder! =)

Most likely a offset issue. Instead of

 

p.worldObj.setBlock((int)p.posX, (int)(p.posY+player.yOffset), (int)p.posZ, MoreApples.customRedstoneAir.blockID);

 

try

p.worldObj.setBlock((int)(p.posX - 0.5D), (int)(p.posY+player.yOffset), (int)(p.posZ - 0.5D), MoreApples.customRedstoneAir.blockID);

    • There's a scheme I got into where they promised to trade Bitcoin for me and take a cut as a commission. Seemed like a good idea at the time. But then, things went south real fast. They ended up transferring   $190,000 worth of my Bitcoin. I was devastated and felt completely helpless. That's when I stumbled upon the Wizard Web Recovery Tool. It was like a beacon of hope amid chaos. With this tool, I could finally start digging into what went wrong and hopefully get my Bitcoin back. Using Wizard Web was surprisingly easy. I just had to plug in some details about my Bitcoin account and let it do its thing. It started scanning the internet, looking for any clues about what happened to my Bitcoin. It felt like having a detective on my side, searching for answers. And guess what? Wizard Web found some leads. It uncovered evidence of the scheme's shady dealings and helped me track down the people responsible for losing my Bitcoin. Armed with this information, I took the case to court. After a long and hard-fought legal battle, the court ruled in my favor. The perpetrators were held accountable for their actions and faced criminal charges for their involvement in the scheme. It was a victory not just for me, but for anyone who's been taken advantage of by these kinds of scams. Thanks to Wizard Web Recovery, I was able to get justice and reclaim what was rightfully mine. It showed me that even in the face of adversity, there's always a way to fight back. And with the right tools and determination, anything is possible.   The following is the contact information for Wizard Web Recovery.   Email: wizard web recovery((@))programmer . net
    • Hello, good morning. I know some programming and I'm interested in mod creation. That's why I've decided to follow a tutorial guide on YouTube by TurtyWurty. https://www.youtube.com/watch?v=DhoX9cmAZqA&t=160s&ab_channel=TurtyWurty I've followed the tutorial perfectly. The problem is that when checking the food, the texture doesn't load for me. However, everything seems fine no matter how much I check. I'm sure it's something trivial, the problem is that I can't find it. Could you help me solve it, please? I leave a zip of my file so you can edit it freely. forge-1.20-Civicraft.rar
    • If you have nvidia graphics, it's important that you make sure Minecraft (and anything Minecraft-related) is set to prefer high performance graphics first. If you only update your AMD drivers it might fix the issue but cause severe performance loss vs Vanilla as it'll be running on the integrated graphics instead of dedicated nvidia graphics
