extends espresso3d.engine.viewport.text.E3DFont

Author:

cmoxley A fixed with font is a font that has even spacing between all characters A texture is divided into a grid of (numColumns x numRows) and each portion of the grid will be 1 symbol. Symbols are then bound to a column/row.

Constructor Detail

E3DFixedWidthFont

public E3DFixedWidthFont(E3DEngine engine,
                         java.lang.String fontID,
                         java.lang.String textureName,
                         int numColumns,
                         int numRows)

Instantiate a fixed width font.

Parameters:

engine - Engine the font will reside in

fontID - Unique ID for the font

textureName - Name of the texture (loaded from a textureset) that contains all the symbols for the font

numColumns - Number of columns in the texture. This will divide the texture up evenly into numColumns and use the space in-between the columns as the place the symbols will reside

numRows - Number of rows in the texture. This will divide the texture up evenly into numRows and use the space in-between the rows as the place the symbols will reside

E3DFixedWidthFont

public E3DFixedWidthFont(E3DEngine engine,
                         java.lang.String fontID,
                         java.lang.String textureName,
                         int numColumns,
                         int numRows,
                         int blendMode)

Instantiate a fixed width font.

Parameters:

engine - Engine the font will reside in

fontID - Unique ID for the font

textureName - Name of the texture (loaded from a textureset) that contains all the symbols for the font

numColumns - Number of columns in the texture. This will divide the texture up evenly into numColumns and use the space in-between the columns as the place the symbols will reside

numRows - Number of rows in the texture. This will divide the texture up evenly into numRows and use the space in-between the rows as the place the symbols will reside

blendMode - Type of blending to use for the font

Method Detail

bindSymbolToTexturePosition

public void bindSymbolToTexturePosition(char symbol,
                                        int row,
                                        int column)

This binds a symbol (a single letter, number, etc) to a certain position on this fonts texture. That position will be where the engine looks on the texture when the symbol is passed into a viewport print statement. Row/Column starts in the upper left hand corner of the texture image with row=1, column=1. For example, row=1 col=1 would give you the portion of the texture starting in the upper left hand corner and extending right symbolWidths pixels and extending down symbolHeights pixels. row=1, col=2 would have an upper left corner starting at symbolWidth + 1 and extending to symbolWidth * 2 and symbolHeight
