★Special features

function

slSpecialFuncCodeA

function

slSpecialFuncCodeB

Setting color codes to enable special features

Format

    #include "sgl.h"

    Uint16 type;

    void slSpecialFuncCodeA( type );
    void slSpecialFuncCodeB( type );

argument

    Uint16 type - Color code to enable special functionality (see below).

Return number

    void - returns nothing.

function

Specify the color code (lower 4 bits) to enable special functions.
For type, sfCOL_01 , sfCOL_23 , sfCOL_45 , sfCOL_67 , sfCOL_89 , sfCOL_ab , sfCOL_cd , sfCOL_ef Specify by connecting them with '|'.

example

    slSpecialCCalcModeNbg1 ( spPRI_Dot );
    slPriorityNbg1 ( 5 );
    slPriorityNbg1 ( 4 );
    slSpecialFuncCodeA ( sfCOL_cd );

Note

Since the last 1 bit of the lower 4 bits of the color code is ignored (this is a hardware specification), for example, if you specify sfCOL_67 , the lower 4 bits are special for colors 6 and 7. The function works.

function

slSpecialFuncSelectB

Specifying a scroll screen using special function code B

Format

    #include "sgl.h"

    Uint16 mode;

    void slSpecialFuncSelectB( mode );

argument

    Uint16 mode - Scrolling screen using special function code B.

Return number

    void - returns nothing.

function

Specifies a scroll screen that uses special function code B.
In mode, NBG0ON , NBG1ON , NBG2ON , NBG3ON , RBG0ON Specify one of them (if specifying multiple, please connect them with '|').

example

    slSpecialPrioModeNbg1 ( spPRI_Dot );
    slPriorityNbg1 ( 5 );
    slPriorityNbg1 ( 4 );
    slSpecialFuncCodeB ( sfCOL_01 );
    slSpecialFuncSelectB ( NBG1ON );

Note

Only the BG plane set with this function uses special function code B; other BG planes All use special function code A. That is why the function slSpecialFuncSelectA does not exist. Conversely, think of it as specifying a surface that does not use special function code A.
