The issue is that you are treating an air block like it was your block:

java.lang.IllegalArgumentException: Cannot get property PropertyEnum{...} as it does not exist in BlockState{block=minecraft:air, properties=[]}

at stevekung.mods.moreplanets.planets.fronos.blocks.BlockFronosTallGrass.canBlockStay(BlockFronosTallGrass.java:125)

at stevekung.mods.moreplanets.common.blocks.BlockFlowerMP.canReplace(BlockFlowerMP.java:62)

Here in your code:

@Override
public boolean canBlockStay(World world, BlockPos pos, IBlockState state)
{
	Block block = world.getBlockState(pos.down()).getBlock();
	BlockType type = (BlockType)state.getValue(VARIANT);

The block you get at the given BlockPos can be ANYTHING, not just your block. You need to check first.

}

I said the BLOCK at that position can be anything, though it will not be null, and the BlockPos certainly will not be null.

 

The problem is you are getting the block at the position BELOW your block, and then assuming that it is also your block, which clearly it usually won't be.

 

You need to check what the actual blockstate is at each position you check before trying to access any specific properties.

Thanks! It can placed properly. But World Generator still crash. -.-

 

My code like this.

Block block = blockState.getBlock();

boolean onPurpleGrass = block == FronosBlocks.purple_grass || block == FronosBlocks.fronos_dirt;

boolean onPlainsGrass = block == FronosBlocks.plains_grass || block == FronosBlocks.fronos_dirt;

boolean onGoldenGrass = block == FronosBlocks.golden_grass || block == FronosBlocks.fronos_dirt;

 

if (block instanceof BlockFronosGrass)

{

onFronosGrass = true;

}

else if (block instanceof BlockPinkGrass)

{

onPinkGrass = true;

}

else if (block instanceof BlockPurpleGrass)

{

onPurpleGrass = true;

}

else if (block instanceof BlockPlainsGrass)

{

onPlainsGrass = true;

}

else

{

onGoldenGrass = true;

}

 

BlockType type = (BlockType)state.getValue(VARIANT);

 

if (type == BlockType.fronos_short_grass || type == BlockType.fronos_medium_grass || type == BlockType.fronos_tall_grass)

{

return onFronosGrass;

}

if (type == BlockType.pink_short_grass || type == BlockType.pink_medium_grass || type == BlockType.pink_tall_grass)

{

return onPinkGrass;

}
