Class TileMapBounds

java.lang.Object
  com.nutiteq.components.TileMapBounds

public class TileMapBounds
extends java.lang.Object

Defines map bounds on pixel map. Definition is done by valid minimum and maximum points on map. For example for a map, that has world at zoom level 0 in 256x256 tile, map bounds on zoom 0 would be min = (0, 0) and max = (255, 255)

Constructor Summary

TileMapBounds(MapPos minPoint, MapPos maxPoint)
Create tile map bounds.

Method Summary

MapPos	calculateCorrection(MapPos middlePoint) Calculate map position correction for it to be within map bounds.
MapPos	getMaxPoint()
MapPos	getMinPoint()
boolean	isWithinBounds(int mapX, int mapY) Is given position on tile map within map bounds

TileMapBounds

public TileMapBounds(MapPos minPoint,
                     MapPos maxPoint)

Create tile map bounds.

Parameters:

minPoint - minimum valid point on map

maxPoint - maximum valid point on map

Method Detail

isWithinBounds

public boolean isWithinBounds(int mapX,
                              int mapY)

Is given position on tile map within map bounds

Parameters:

mapX - position x

mapY - position y

Returns:

if given point is within map bounds
