Hello,

 

I'm trying to make a mod where a block (that I named "Terra Stone") speeds up the growth of plants around it, so how would I go about doing that? I'm new to Java and need help with this, so I would appreciate all the help I can get. So is there a way to do this? I would assume you need to make a TileEntity for the block, but I don't understand how, and probably screwed it up, big time.

 

Can someone help me? I'm using MCP and ModLoader on Minecraft 1.2.5. I'll post my codes below:

 

package net.minecraft.src;
import java.util.Random;

public class mod_TerraBlock extends BaseMod
{
public static final Block terraBlock = new BlockTerraStone(127,0).setHardness(50F).setResistance(2000.0F).setBlockName("mvas").setLightValue(0.80F);

public mod_TerraBlock()
{
	ModLoader.registerBlock(terraBlock);
	terraBlock.blockIndexInTexture = ModLoader.addOverride("/terrain.png","/terra.png");
	ModLoader.addName(terraBlock, "Terra Stone");

	ModLoader.addRecipe(new ItemStack(terraBlock, 1), new Object []{
		"*%*","*#*","***", Character.valueOf('%'), Item.bucketWater, Character.valueOf('#'), Block.obsidian, Character.valueOf('*'), Block.dirt,
	});
}

public String getVersion()
{
	return "3.14159265";
}
public void load()
{
}
}

 

package net.minecraft.src;
import java.util.Random;

public class BlockTerraStone extends Block
{
public BlockTerraStone(int i, int j)
{
	super(i,j,Material.rock);
}

public int idDropped(int i, Random random)
{
	return mod_TerraBlock.terraBlock.blockID;
}

public int quantityDropped(Random random)
{
	return 1;
}
}

 

and my murdered attempt at TileEntity

package net.minecraft.src;

import java.util.Random;

public class TileEntityTerraStone extends TileEntity
{
public mod_Block.terraStone;

public void checkForAdjacentCrops()

public boolean 
{
	worldObj.getBlockId(xCoord, yCoord, zCoord)

 

I obviously really need help on the last one, so thank you in advanced!

Since growth in MC is handled via a random tick, what you could do is in your tileentity's update loop use world.scheduleBlockUpdate on each crop block within range. OR you could manually increase the metadata for each crop block in range which should have the same effect. for wheat at least. The first solution is better as you are letting the crop do the update itself.

Okay thank you, I think I can figure that out, but do you have any idea how it would read that crops are nearby? That's where I'm really stuck

try doing Block.blockList[world.getBlockID()) instanceof BlockCrop that should point you the right way

try doing Block.blockList[world.getBlockID()) instanceof BlockCrop that should point you the right way

 

package net.minecraft.src;

import java.util.Random;

public class TileEntityTerraStone extends TileEntity
{
public mod_Block.terraStone;

public void checkForAdjacentCrops()
{
	Block.blockList[world.getBlockID()]
}

public boolean 
{
	worldObj.getBlockID(xCoord, yCoord, zCoord)
}

 

Like this?

You'll need to fix the method by doing

//This method should be run on each block around the stone that increases the growth
public void updateAdjacentCrop(World world, int x, int y, int z)
{
	if(Block.blockList[world.getBlockID(x,y,z)] instanceof BlockCrop)
{
     //schedule the update here. 
}
}

package net.minecraft.src;

import java.util.Random;

public class TileEntityTerraStone extends TileEntity
{	
public void updateAdjacentCrop(World world, int x, int y, int z)
{
	if(Block.blockList[world.getBlockID(x,y,z)] instanceof BlockCrop)
	{
		if(random.nextInt(1) == 0)
	}
}
}

 

Did I do something extremely wrong?

no it looks like that should work to me.

Thank you! You were a lot of help to me!

Ive run into errors

 

== ERRORS FOUND ==

^
2 errors
==================

 

How can I resolve these?

 

here's where I've gotten in my code:

package net.minecraft.src;
import java.util.Random;
public class TileEntityTerraStone extends TileEntity
{
     public Block terraBlock;

     public void updateAdjacentCrop(World world, int x, int y, int z)
   {
       if(Block.blockList[worldObj.getBlockId(xCoord ,yCoord ,zCoord)] instanceof BlockCrops)
      {
         if(Random.nextInt(1) == 0);
      }
   }
}

use instead

if(Random.nextInt(1) == 0);

this:

if(world.rand.nextInt(1) == 0);
