Help with making a block that generates in the sky

[MINERGUY67880]

Hello everybody! I am making a mod with gasses but I want them to stay in the world and not dissapear when they reach the top. I need to know how to make a block generate on 100% of layer 255?

[MINERGUY67880]

Does anyone know? Because i am completely stumped.

[coolboy4531]

You could use a loop, and set all the blocks from your starting point as air, until it reaches the height of 255.

[MINERGUY67880]

Sorry to sound like a noob, but how do i do that?

 

[robustus]

Try the onBlockPlacedBy method, when the gas block comes into the world have it check to see if the block above it is air, if its air set current block to air and set the block above it to the gas block and just make sure the block won't go higher than 255 or whatever you want it to sit at.  so if the block above it is air and not greater than 255 it will go up

Ah, thanks!

[MINERGUY67880]

Sorry, i have 2 more questions. 1. Is there a thing that returns the name of the block above another block?

 

Example: C = custom block that returns the name of the above block, A = air

                     

                      A

                      C

It would say "air" in the eclipse console if you hooked it up to a printline thing?

 

2. How do I make the gas stop when the said air block is on layer 255?

 

And can I please have some code pieces? I don't really know advanced java.

2. How do I make the gas stop when the said air block is on layer 255?

 

if(y >= 255) { return; }

[MINERGUY67880]

Thanks

[MINERGUY67880]

Can anyone help me with the first question?

[robustus]

Try

 

if (par1World.getBlockId(par2, par3 + 1, par4) == 0 && par3 <= 255)
{
par1World.setBlock(par2, par3 + 1, par4, yourgasblock);
par1World.setBlock(par2, par3, par4, 0);
}

 

par2, par3, par4 are x, y, z

[MINERGUY67880]

Another nooby question, where do i put that code?

[larsgerrits]

In the updateTick (right method name?) method in your block class.

[MINERGUY67880]

So do i put

public void updateTick() {
    	if (par1World.getBlockId(par2, par3 + 1, par4) == 0 && par3 <= 255)
    	{
    	par1World.setBlock(par2, par3 + 1, par4, BlockGasSteam);
    	par1World.setBlock(par2, par3, par4, 0);
    	}
    }

   

[larsgerrits]

That should work, but that's going 20 blocks up in a second, so you might want to add a timer.

[MINERGUY67880]

Heres my code for the Gas Block file:

package miner.miner.technicraft.oceans.blocks;


import java.util.Random;

import miner.miner.technicraft.oceans.client.gui.creativetabs.TCOceansCreativeTabs;
import miner.miner.technicraft.oceans.TechnicCraftOceans;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.entity.EntityLiving;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.World;
import net.minecraftforge.fluids.BlockFluidClassic;
import net.minecraftforge.fluids.BlockFluidFinite;
import net.minecraftforge.fluids.Fluid;

public class BlockGasSteam extends BlockFluidFinite {
    public String texture;

    public BlockGasSteam(int id, String key, Fluid fluid) {
        super(id, fluid, Material.water);
        this.texture = key;
        this.setCreativeTab(TCOceansCreativeTabs.blocksTab);

        fluid.setBlockID(this);
        setUnlocalizedName(key); 
        
        
        
    }
    
    
    
    
	   

    @Override
    public void registerIcons(IconRegister register) {
        blockIcon = register.registerIcon(TechnicCraftOceans.modID + ":" + texture);
        getFluid().setIcons(blockIcon); 
        
        
        
        
    }

    @Override
    public int colorMultiplier(IBlockAccess world, int x, int y, int z) {
        return 0xaaaaaa;
        
       
        
    }
    public void updateTick() {
    	if (par1World.getBlockId(par2, par3 + 1, par4) == 0 && par3 <= 255)
    	{
    	par1World.setBlock(par2, par3 + 1, par4, BlockGasSteam);
    	par1World.setBlock(par2, par3, par4, 0);
    	}
    }
}

I am getting errors on par1World, par2, par3, par4 then the other par3 and just about everything else! Is there anything I need to change or move? Or do i just need to add ints/variables?

Hi

 

I think the core of the problem here is that we're not really understanding what you want to do.

 

i.e. you're making a block that is a gas, but then you mention something about the block moving upwards and stopping at layer 255?

 

So my impression is that you want something like

eg a toxic bog of eternal stench that belches out a block of gas occasionally which slowly rises its way up to layer 255 then stops and just sits there.

 

Is that right?  Perhaps if you provide a bit more explanation and background we can help you more...

That is exactly what I want!

Heres my code for the Gas Block file:

public void updateTick() {
if (par1World.getBlockId(par2, par3 + 1, par4) == 0 && par3 <= 255)
{
par1World.setBlock(par2, par3 + 1, par4, BlockGasSteam);
par1World.setBlock(par2, par3, par4, 0);
}
}

I am getting errors on par1World, par2, par3, par4 then the other par3 and just about everything else! Is there anything I need to change or move? Or do i just need to add ints/variables?

First you will need to understand basic Java, then you will immediately understand why you are getting errors with par1World, etc.

 

Second, you can't just add any method you want and expect it to run automatically. Sure, there is a method named updateTick in Block, but you don't have any of the arguments. Look in the Block class and you will see:

@Override
public void updateTick(World world, int x, int y, int z, Random rand) {}

That's the correct method signature, and if you deviate at all from that your method is no longer a Block class method, meaning you'd have to call it yourself.

 

Now that you have the correct method signature, you just have to make your block tick randomly or schedule ticks for it. Look at some ticking vanilla blocks to see how they do it.

Ah, thanks.
