function

slSpecialFuncCodeB

Color code settings to enable special functions

Form

    #include "sgl.h"

    Uint16 type;

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

argument

    Uint16 type --Color code that enables special features (see below).

Number of returns

    void --Nothing is returned.

function

    Specifies the color code (lower 4 bits) for which the special function is enabled.

    type is
        sfCOL_01 , sfCOL_23 , sfCOL_45 , sfCOL_67 , sfCOL_89 , sfCOL_ab ,
        sfCOL_cd , sfCOL_ef
    Are specified by connecting them with'|'.

Example

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

caution

    Of the lower 4 bits of the color code, the last 1 bit is ignored (hardware specification). For example, if sfCOL_67 is specified, the lower 4 bits are special for colors 6 and 7. The function works.

function

slSpecialFuncSelectB

Specifying a scroll screen that uses special function code B

Form

    #include "sgl.h"

    Uint16 mode;

    void slSpecialFuncSelectB (mode);

argument

    Uint16 mode --Scroll screen using special function code B.

Number of returns

    void --Nothing is returned.

function

    Specifies a scroll screen that uses special function code B.

    In mode,
        NBG0ON , NBG1ON , NBG2ON , NBG3ON , RBG0ON
    Specify one of the above (if you specify more than one, connect them with'|').

Example

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

caution

    Only the BG surface set by this function uses the special function code B, and the other BG surfaces are
    All use special function code A. That is why there is no function called slSpecialFuncSelectA. Conversely, think of specifying a surface that does not use the special function code A.
