Method Detail

onOpacityChange

public void onOpacityChange(int localX,
                            int blockY,
                            int localZ,
                            int opacity)

Description copied from interface: IHeightMap

Sets the opacity at the given position to the given value.

Specified by:

onOpacityChange in interface IHeightMap

Parameters:

localX - local block x-coordinate (0..15)

blockY - global block y-coordinate

localZ - local block z-coordinate (0..15)

opacity - new opacity (0..255)

getTopBlockY

public int getTopBlockY(int localX,
                        int localZ)

Description copied from interface: IHeightMap

Returns the y-coordinate of the highest non-transparent block in the specified block-column.

Specified by:

getTopBlockY in interface IHeightMap

Parameters:

localX - local block x-coordinate (0..15)

localZ - local block z-coordinate (0..15)

Returns:

Y position of the top non-transparent block, or very low (far below the min world height) if one doesn't exist

getTopBlockYBelow

public int getTopBlockYBelow(int localX,
                             int localZ,
                             int blockY)

Description copied from interface: IHeightMap

Returns the y-coordinate of the highest non-transparent block that is below the given blockY.

Specified by:

getTopBlockYBelow in interface IHeightMap

Parameters:

localX - local block x-coordinate (0..15)

localZ - local block z-coordinate (0..15)

blockY - only positions below or at this Y coordinate will be retuirned

Returns:

Y position of the top non-transparent block below blockY, or very low (far below the min world height) if one doesn't exist

getLowestTopBlockY

public int getLowestTopBlockY()

Description copied from interface: IHeightMap

Out of the highest non-opaque blocks from all block columns in the column, returns the y-coordinate of the lowest block.

Specified by:

getLowestTopBlockY in interface IHeightMap

Returns:

the minimum of all top block coordinates in this heightmap instance
