getChunk

public abstract net.minecraft.world.chunk.Chunk getChunk(net.minecraft.util.math.BlockPos pos)

getBlockState

public abstract net.minecraft.block.state.IBlockState getBlockState(net.minecraft.util.math.BlockPos pos)

isBlockLoaded

public abstract boolean isBlockLoaded(net.minecraft.util.math.BlockPos pos)

isBlockLoaded

public abstract boolean isBlockLoaded(net.minecraft.util.math.BlockPos blockPos,
                                      boolean allowEmpty)

                                         int z,
                                         boolean allowEmpty)

isOutsideBuildHeight

public boolean isOutsideBuildHeight(net.minecraft.util.math.BlockPos pos)

This @Overwrite allows World to "see" blocks outside of 0..255 height range.

Parameters:

pos - block position

Returns:

true if the given position is outside world height range

Reason:

It's very simple method and this seems to be the cleanest way to modify it.

getLight

public int getLight(net.minecraft.util.math.BlockPos pos)

Parameters:

pos - block positionn

Returns:

light value at the given position

Reason:

Replace World.getLight(BlockPos) with method that works outside of 0..255 height range. It would be possible to fix it using @Redirect and @ModifyConstant but this way is much cleaner, especially for simple method. A @ModifyConstant wouldn't work because it can't replace comparison to 0. This is because there is a special instruction to compare something to 0, so the constant is never used.

Note: The getLight method is used in parts of game logic and entity rendering code. Doesn't directly affect block rendering.
