Class ShadedTexture

java.lang.Object
  com.brackeen.javagamebook.graphics3D.texture.Texture
      com.brackeen.javagamebook.graphics3D.texture.ShadedTexture

public final class ShadedTexture

extends Texture

The ShadedTexture class is a Texture that has multiple shades. The texture source image is stored as a 8-bit image with a palette for every shade.

Field Summary

static int	MAX_LEVEL
static int	NUM_SHADE_LEVELS

Constructor Summary

ShadedTexture(byte[] buffer, int widthBits, int heightBits, java.awt.image.IndexColorModel palette)
Creates a new ShadedTexture from the specified 8-bit image buffer and palette.

ShadedTexture(byte[] buffer, int widthBits, int heightBits, java.awt.image.IndexColorModel palette, java.awt.Color targetShade)
Creates a new ShadedTexture from the specified 8-bit image buffer, palette, and target shaded.

Method Summary

short	getColor(int x, int y) Gets the 16-bit color of this Texture at the specified (x,y) location, using the default shade level.
short	getColor(int x, int y, int shadeLevel) Gets the 16-bit color of this Texture at the specified (x,y) location, using the specified shade level.
short	getColorCurrRow(int x, int shadeLevel) Gets the color at the specified x location at the specified shade level.
int	getDefaultShadeLevel() Gets the default shade level that is used when getColor() is called.
void	makeShadeTable(java.awt.Color targetShade) Creates the shade table for this ShadedTexture.
void	setCurrRow(int y) Sets the current row for getColorCurrRow().
void	setDefaultShadeLevel(int level) Sets the default shade level that is used when getColor() is called.

Constructor Detail

ShadedTexture

public ShadedTexture(byte[] buffer,
                     int widthBits,
                     int heightBits,
                     java.awt.image.IndexColorModel palette)

Creates a new ShadedTexture from the specified 8-bit image buffer and palette. The width of the bitmap is 2 to the power of widthBits, or (1 << widthBits). Likewise, the height of the bitmap is 2 to the power of heightBits, or (1 << heightBits). The texture is shaded from it's original color to black.

ShadedTexture

public ShadedTexture(byte[] buffer,
                     int widthBits,
                     int heightBits,
                     java.awt.image.IndexColorModel palette,
                     java.awt.Color targetShade)

Creates a new ShadedTexture from the specified 8-bit image buffer, palette, and target shaded. The width of the bitmap is 2 to the power of widthBits, or (1 << widthBits). Likewise, the height of the bitmap is 2 to the power of heightBits, or (1 << heightBits). The texture is shaded from it's original color to the target shade.

Method Detail

makeShadeTable

public void makeShadeTable(java.awt.Color targetShade)

Creates the shade table for this ShadedTexture. Each entry in the palette is shaded from the original color to the specified target color.

setDefaultShadeLevel

public void setDefaultShadeLevel(int level)

Sets the default shade level that is used when getColor() is called.

getDefaultShadeLevel

public int getDefaultShadeLevel()

Gets the default shade level that is used when getColor() is called.

getColor

public short getColor(int x,
                      int y)

Gets the 16-bit color of this Texture at the specified (x,y) location, using the default shade level.

Specified by:

getColor in class Texture

getColor

public short getColor(int x,
                      int y,
                      int shadeLevel)

Gets the 16-bit color of this Texture at the specified (x,y) location, using the specified shade level.

setCurrRow

public void setCurrRow(int y)

Sets the current row for getColorCurrRow(). Pre-calculates the offset for this row.

getColorCurrRow

public short getColorCurrRow(int x,
                             int shadeLevel)

Gets the color at the specified x location at the specified shade level. The current row defined in setCurrRow is used.
