创建新耕地的时候无法判断周围的流体 - Mod问答

问题：1.耕地无法检测周围的流体或者方块
2.周围没有需要的流体或者方块不会变回沙子

目标：
检测到对应流体不变回沙子
周围没有需要的方块和流体会和原版耕地一样的速度变回沙子

详细代码如下

package com.github.sunmilksong.blocks;
import com.github.sunmilksong.init.ModBlocks;
import net.minecraft.block.Block;
import net.minecraft.block.BlockFarmland;
import net.minecraft.block.SoundType;

import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraftforge.common.FarmlandWaterManager;

public class BlockFarm extends BlockSk {
public BlockFarm(String name, Material material, SoundType sound) {
super(name,material,sound);
this.setDefaultState(this.blockState.getBaseState());
this.setTickRandomly(true);
ModBlocks.BLOCKS.add(this);
}
protected static void turnToSand(World worldIn, BlockPos pos) {
worldIn.setBlockState(pos, Blocks.SAND.getDefaultState());
}
@Override
public void updateTick(World worldIn, BlockPos pos, IBlockState state, Random rand) {
if (!this.hasLiquidOrBlock(worldIn, pos))
{
turnToSand(worldIn, pos);
}
}
private boolean hasLiquidOrBlock(World worldIn, BlockPos pos)
{
for (BlockPos.MutableBlockPos BM : BlockPos.getAllInBoxMutable(pos.add(-1, 0, -1), pos.add(1, -1, 1))) {
if (worldIn.getBlockState(BM).getMaterial() == Material.LAVA &&
worldIn.getBlockState(BM).getMaterial() == Material.WATER) ;
{
return true;
}
}
return worldIn.setBlockState(pos, Blocks.SAND.getDefaultState());
}
@Override
public void neighborChanged(IBlockState state, World worldIn, BlockPos pos, Block blockIn, BlockPos fromPos) {
super.neighborChanged(state, worldIn, pos, blockIn, fromPos);
if (worldIn.getBlockState(pos.up()).getMaterial().isSolid()) {
turnToSand(worldIn, pos);
}
}
@Override
public void onBlockAdded(World worldIn, BlockPos pos, IBlockState state) {
super.onBlockAdded(worldIn, pos, state);
if (worldIn.getBlockState(pos.up()).getMaterial().isSolid()) {
turnToSand(worldIn, pos);
}
}
@Override
public Item getItemDropped(IBlockState state, Random rand, int fortune) {
return Blocks.SAND.getItemDropped(Blocks.SAND.getDefaultState(), rand, fortune);
}
}

为什么不直接参考原版耕地呢

private boolean hasWater(World worldIn, BlockPos pos)
{
for (BlockPos.MutableBlockPos blockpos$mutableblockpos : BlockPos.getAllInBoxMutable(pos.add(-4, 0, -4), pos.add(4, 1, 4)))
{
if (worldIn.getBlockState(blockpos$mutableblockpos).getMaterial() == Material.WATER)
{
return true;
}
}
return net.minecraftforge.common.FarmlandWaterManager.hasBlockWaterTicket(worldIn, pos);
}

复制代码

public void updateTick(World worldIn, BlockPos pos, IBlockState state, Random rand)
{
int i = ((Integer)state.getValue(MOISTURE)).intValue();
if (!this.hasWater(worldIn, pos) && !worldIn.isRainingAt(pos.up()))
{
if (i > 0)
{
worldIn.setBlockState(pos, state.withProperty(MOISTURE, Integer.valueOf(i - 1)), 2);
}
else if (!this.hasCrops(worldIn, pos))
{
turnToDirt(worldIn, pos);
}
}
else if (i < 7)
{
worldIn.setBlockState(pos, state.withProperty(MOISTURE, Integer.valueOf(7)), 2);
}
}

道家深湖

除了判断WATER，还有个Blocks.FLOWING_WATER别忘了
另外我觉得楼上那种检测Material的也挺好

道家深湖

f (this.hasLiquidOrBlock(worldIn, pos))
      {
         worldIn.setBlockState(pos,ModBlocks.SOUL_SAND.getDefaultState());
      }
      else if  (!this.hasLiquidOrBlock(worldIn, pos))

以及你这一段有点迷啊，前面if判断好了，后面你为啥不直接else呢，还要再判断一次elseif有点多余吧
