All Implemented Interfaces:

com.badlogic.gdx.ai.msg.Telegraph

public class RenderStorage
extends java.lang.Object
implements com.badlogic.gdx.ai.msg.Telegraph

A RenderStorage is container which saves RenderChunks used for chunks storing rendering-data. It manages which Chunks must be transformed to RenderChunks.

RenderStorage()	Creates a new renderstorage.

Method Summary

Modifier and Type	Method	Description
void	addCamera(Camera camera)	avoids duplicates

RenderCell	getCell(Coordinate coord)	If the cell can not be found returns RenderChunk.CELLOUTSIDE.
RenderCell	getCell(Point point)	If the block can not be found returns null pointer.
RenderChunk	getChunk(int chunkX, int chunkY)	Get the chunk with the given chunk coords from the active pool.
RenderChunk	getChunk(Coordinate coord)	get the chunk where the coordinates are on.
java.util.LinkedList<RenderChunk>	getData()

boolean	handleMessage(com.badlogic.gdx.ai.msg.Telegram msg)
boolean	isClipped(Coordinate coords)	get if a coordinate is clipped
void	occlusionCulling(RenderChunk chunk)	performs a simple clipping check by looking at the direct neighbours.
void	preUpdate(float dt)
RenderCell	refreshCell(Coordinate coord, byte id, byte value)	creates a new RenderCell instance at the coordinate

Constructor Detail

RenderStorage

public RenderStorage()

Creates a new renderstorage.

Method Detail

refreshCell

public RenderCell refreshCell(Coordinate coord,
                              byte id,
                              byte value)

creates a new RenderCell instance at the coordinate

Parameters:

coord -

id -

value -

Returns:

the instance or null if the process failed

preUpdate

public void preUpdate(float dt)

Parameters:

dt -

update

public void update(float dt)

Parameters:

dt -

setLightFlag

public void setLightFlag(Coordinate coord)

Marks this block as "dirty".

Parameters:

coord -

bakeChunks

public void bakeChunks()

Clears the the content of the used RenderChunks then after refilling them calculates the renderdata (shadows, AO, occlusion culling). Very heavy operation.

getChunk

public RenderChunk getChunk(Coordinate coord)

get the chunk where the coordinates are on. Worst case O(n). Average case O(1).

Parameters:

coord - not altered

Returns:

can return null if not loaded

getChunk

public RenderChunk getChunk(int chunkX,
                            int chunkY)

Get the chunk with the given chunk coords from the active pool.
Runtime: O(c) c: amount of chunks -> O(1)

Parameters:

chunkX -

chunkY -

Returns:

if not in memory returns null

getCell

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

Returns a block without checking the parameters first. Good for debugging and also faster. O(n)

Parameters:

x - coordinate

y - coordinate

z - coordinate

Returns:

the single block you wanted

getCell

public RenderCell getCell(Coordinate coord)

If the cell can not be found returns RenderChunk.CELLOUTSIDE.

Parameters:

coord - transform safe

Returns:

getCell

public RenderCell getCell(Point point)

If the block can not be found returns null pointer.

Parameters:

point - transform safe

Returns:

occlusionCulling

public void occlusionCulling(RenderChunk chunk)

performs a simple clipping check by looking at the direct neighbours. O(n) where n is blocks in chunk

Parameters:

chunk -

getData

public java.util.LinkedList<RenderChunk> getData()

Returns:

addCamera

public void addCamera(Camera camera)

avoids duplicates

Parameters:

camera -

isClipped

public boolean isClipped(Coordinate coords)

get if a coordinate is clipped

Parameters:

coords -

Returns:

getZRenderingLimit

public float getZRenderingLimit()

renders to this layer not including

Returns:

coordinate

setZRenderingLimit

public void setZRenderingLimit(float height)

renders to this layer not including

Parameters:

height - game space

handleMessage

public boolean handleMessage(com.badlogic.gdx.ai.msg.Telegram msg)

Specified by:

handleMessage in interface com.badlogic.gdx.ai.msg.Telegraph

dispose

public void dispose()
