Constructor Detail

SparseMisoSceneModel

public SparseMisoSceneModel(int swidth,
                            int sheight)

Creates a scene model with the specified bounds.

Parameters:

swidth - the width of a single section (in tiles).

sheight - the height of a single section (in tiles).

SparseMisoSceneModel

public SparseMisoSceneModel()

Creates a blank model suitable for unserialization.

Method Detail

getInterestingObjects

public void getInterestingObjects(ArrayList<ObjectInfo> list)

Adds all interesting ObjectInfo records in this scene to the supplied list.

getAllObjects

public void getAllObjects(ArrayList<ObjectInfo> list)

Adds all ObjectInfo records in this scene to the supplied list.

visitObjects

public void visitObjects(SparseMisoSceneModel.ObjectVisitor visitor)

Informs the supplied visitor of each object in this scene.

visitObjects

public void visitObjects(SparseMisoSceneModel.ObjectVisitor visitor,
                         boolean interestingOnly)

Informs the supplied visitor of each object in this scene.

Parameters:

interestingOnly - if true, only the interesting objects will be visited.

getBaseTileId

public int getBaseTileId(int col,
                         int row)

Description copied from class: MisoSceneModel

Returns the fully qualified tile id of the base tile at the specified coordinates. -1 will be returned if there is no tile at the specified coordinate.

Specified by:

getBaseTileId in class MisoSceneModel

setBaseTile

public boolean setBaseTile(int fqBaseTileId,
                           int col,
                           int row)

Description copied from class: MisoSceneModel

Updates the tile at the specified location in the base layer.

Note that if there are fringe tiles associated with this scene, calling this method may result in the surrounding fringe tiles being cleared and subsequently recalculated. This should not be called on a displaying scene unless you know what you are doing.

Specified by:

setBaseTile in class MisoSceneModel

Parameters:

fqBaseTileId - the fully-qualified tile id (@see TileUtil#getFQTileId}) of the tile to set.

col - the x-coordinate of the tile to set.

row - the y-coordinate of the tile to set.

Returns:

false if the specified tile coordinates are outside of the scene and the tile was not saved, true otherwise.

setDefaultBaseTileSet

public void setDefaultBaseTileSet(int tileSetId)

Description copied from class: MisoSceneModel

Updates the default base tileset id for this scene.

Overrides:

setDefaultBaseTileSet in class MisoSceneModel

getDefaultBaseTileSet

public int getDefaultBaseTileSet()

Description copied from class: MisoSceneModel

Scene models can return a default tileset to be used when no base tile data exists for a particular tile.

Overrides:

getDefaultBaseTileSet in class MisoSceneModel

getObjects

public void getObjects(Rectangle region,
                       ObjectSet set)

Description copied from class: MisoSceneModel

Populates the supplied object set with info on all objects whose origin falls in the requested region.

Specified by:

addObject

public boolean addObject(ObjectInfo info)

Description copied from class: MisoSceneModel

Adds an object to this scene.

Specified by:
