Package net.mtrop.doom.map.data

Class Reject

java.lang.Object

net.mtrop.doom.map.data.Reject

All Implemented Interfaces:

BinaryObject

public class Reject
extends Object
implements BinaryObject

Represents the Reject lump.

The reject lump is a lookup grid that hold information on what sectors can "see" other sectors on the map used for thing sight algorithms.

Constructor Details

Reject

public Reject(int sectors)

Creates a new blank reject grid.

Parameters:

sectors - the number of sectors.

Method Details

getSectorIsVisibleTo

public boolean getSectorIsVisibleTo(int sectorIndex,
 int targetSectorIndex)

Checks whether a sector is visible from another.

Parameters:

sectorIndex - the sector index viewing from.

targetSectorIndex - the sector index viewing into.

Returns:

true if so, false if not.

setSectorIsVisibleTo

public void setSectorIsVisibleTo(int sectorIndex,
 int targetSectorIndex,
 boolean flag)

Sets whether a sector is visible from another.

Parameters:

sectorIndex - the sector index viewing from.

targetSectorIndex - the sector index viewing into.

flag - true if visible, false if not.

readBytes

public void readBytes(InputStream in)
               throws IOException

Description copied from interface: BinaryObject

Reads from an InputStream and sets this object's fields. Only reads the amount of bytes that it takes to read a single instance of the object. Note that not every object may have a consistent length!

Specified by:

readBytes in interface BinaryObject

Parameters:

in - the InputStream to read from.

Throws:

IOException - if a read error occurs.

writeBytes

public void writeBytes(OutputStream out)
                throws IOException

Description copied from interface: BinaryObject

Writes this object to an OutputStream.

Specified by:

writeBytes in interface BinaryObject

Parameters:

out - the OutputStream to write to.

Throws:

IOException - if a write error occurs.
