com.bombinggames.wurfelengine.core.map.rendering.RenderChunk

public class RenderChunk
extends java.lang.Object

Stores display data for a Chunk.

This may is outdated:
If a cell contains no block/air then the shared CELLOUTSIDE is used.

Field Detail

CELLOUTSIDE

public static final RenderCell CELLOUTSIDE

In theory if in a cell is no data available use this block. Uses air internally.
block-by-block differences must not be used because this is a shared object. Topological Depth Sort needs individual containers. If the topolgogical sort would be removed from the engine this could be again be used.

Constructor Detail

RenderChunk

public RenderChunk(Chunk chunk)

With init

Parameters:

chunk - linked chunk which is then rendered

Method Detail

clearPool

public static void clearPool()

clears the pool to free memory

initData

public void initData()

fills every render cell based on the data from the map

getCell

public RenderCell getCell(Coordinate coord)

Parameters:

coord - only coordinates which are in this chunk

Returns:

getCell

public RenderCell getCell(int x,
                          int y,
                          int z)

Cells above the map return RenderChunk.CELLOUTSIDE.

Parameters:

x - coordinate, must be contained in this chunk

y - coordinate, must be contained in this chunk

z - coordinate, must be contained in this chunk

Returns:

should not return null unless something went wrong.

getData

public RenderCell[][][] getData()

get the pointer to the data

Returns:

resetClipping

protected void resetClipping()

Resets the clipping for every block.

resetShadingFor

public void resetShadingFor(int idexX,
                            int idexY,
                            int idexZ)

Resets the shading for one block. Calculates drop shadow from blocks above.

Parameters:

idexX - index pos

idexY - index pos

idexZ - index pos

getTopLeftCoordinateX

public int getTopLeftCoordinateX()

Returns:

getTopLeftCoordinateY

public int getTopLeftCoordinateY()

Returns:

getIterator

public DataIterator3D<RenderCell> getIterator(int startingZ,
                                              int limitZ)

Returns an iterator which iterates over the data in this chunk.

Parameters:

startingZ -

limitZ - the last layer (including).

Returns:
