Method Detail

XToTileX

public static int XToTileX(int x,
                           int tileGridXOffset,
                           int tileWidth)

Converts a pixel's X coordinate into a horizontal tile index relative to a given tile grid layout specified by its X offset and tile width.

If tileWidth < 0, the results of this method are undefined. If tileWidth == 0, an ArithmeticException will be thrown.

Throws:

ArithmeticException - If tileWidth == 0.

YToTileY

public static int YToTileY(int y,
                           int tileGridYOffset,
                           int tileHeight)

Converts a pixel's Y coordinate into a vertical tile index relative to a given tile grid layout specified by its Y offset and tile height.

If tileHeight < 0, the results of this method are undefined. If tileHeight == 0, an ArithmeticException will be thrown.

Throws:

ArithmeticException - If tileHeight == 0.
