I have been having trouble  making a water block that like the vanilla block has certain heights it can achieve. But unlike the normal water block this block degrades the height of the parent block as it sets the preceding blocks. Also it moves blocks as well (you don't have to worry about that that is not the problem nor is it yet been added).

 

it does not duplicate but just sits except when you place it near other normal water blocks.

 

package IVWeather.iv.block;

 

import net.minecraft.block.Block;

import net.minecraft.block.BlockLiquid;

import net.minecraft.block.material.Material;

import net.minecraft.init.Blocks;

import net.minecraft.world.IBlockAccess;

import net.minecraft.world.World;

 

public class BlockRushingWater extends BlockLiquid{

 

public float LiquidHieght;

 

public BlockRushingWater(Material m_1) {

super(m_1);

LiquidHieght = .1F;

setBlockBounds(0, 0, 0, 1, LiquidHieght, 1);

}

 

public void spreadOverArea(int par1, int par2, int par3, IBlockAccess iba, World world) {

 

 

 

int a1 = par1;

int a2 = par1;

int a3 = par1;

Block blockA = iba.getBlock(a1 - 1, a2, a3);

Block blockB = iba.getBlock(a1 + 1, a2, a3);

Block blockC = iba.getBlock(a1, a2, a3 - 1);

Block blockD = iba.getBlock(a1, a2, a3 + 1);

 

    int i = world.getBlockMetadata( par1, par2, par3);

 

 

if(this.LiquidHieght > .05) {

if(blockA == Blocks.air) {

  world.setBlock(a1 - 1, a2, a3, Block.getBlockById(Block.getIdFromBlock(this) - 1), i, 2);

    world.scheduleBlockUpdate(par1, par2, par3, Block.getBlockById(Block.getIdFromBlock(this) - 1), tickRate(world));

  this.LiquidHieght = LiquidHieght/ 2;

}

 

if(blockB == Blocks.air) {

world.setBlock(a1 + 1, a2, a3, Block.getBlockById(Block.getIdFromBlock(this) - 1), i, 2);

world.scheduleBlockUpdate(par1, par2, par3, Block.getBlockById(Block.getIdFromBlock(this) - 1), tickRate(world));

this.LiquidHieght = LiquidHieght/ 2;

}

 

if(blockC == Blocks.air) {

world.setBlock(a1, a2, a3 + 1, Block.getBlockById(Block.getIdFromBlock(this) - 1), i, 2);

world.scheduleBlockUpdate(par1, par2, par3, Block.getBlockById(Block.getIdFromBlock(this) - 1), tickRate(world));

this.LiquidHieght = LiquidHieght/ 2;

}

 

if(blockD == Blocks.air) {

world.setBlock(a1, a2, a3 - 1, Block.getBlockById(Block.getIdFromBlock(this) - 1), i, 2);

world.scheduleBlockUpdate(par1, par2, par3, Block.getBlockById(Block.getIdFromBlock(this) - 1), tickRate(world));

this.LiquidHieght = LiquidHieght/ 2;

}

}

}

 

public void MakeHieghtAmount() {

this.setBlockBounds(0, 0, 0, 1, LiquidHieght, 1);

}

 

public void accumulate() {

 

}

 

 

 

}

 

Hi

 

I'm not sure I understand your code.

What are you expecting to call spreadOverArea?

 

Forge has something similar to this already.  Look at BlockFluidFinite  (and in the minecraftforge\fluids package in general).  I don't know how to use it properly myself, never tried, but it's intended for exactly this sort of thing.  A google will probably show up a tutorial or at least a few GitHubs where people have used it before.

 

-TGG

 

WTF Does this code mean:

Block.getBlockById(Block.getIdFromBlock(this)

You are basicly getting a block from a id which you get from a block. You could've just used

this

instead of that chain of code....

because it would give me an error message if i did not

Anyway, in addition to the specific questions about your code, I think you should consider using the Fluids that are now implemented in Minecraft Forge.  There is a whole bunch of functionality there that might be useful to your need.
