function

slColOffsetOn

Screen settings affected by color offset values

Format

    #include "sgl.h"

    Uint16 mode;

    void slColOffsetOn( mode );

argument

    Uint16 mode - Screen affected by color offset value.

Return number

    void - returns nothing.

function

Set the screen affected by the color offset value.
In mode, NBG0ON , NBG1ON , NBG2ON , NBG3ON , RBG0ON , LNCLON , SPRON , OFF is entered.
If you want to set the drawing settings for multiple scroll planes at the same time, specify the mode for each plane by connecting them with "|".

example

    Apply color offset to NBG1 and NBG3.

    slColOffsetOn ( NBG1ON | NBG3ON );

    Disable all BG color offsets.

    slColOffsetOn ( OFF );

Note

If you specify OFF for the mode argument, color offset will be turned off for all faces.

function

slColOffsetAUse

Set the screen affected by the color offset value

Format

    #include "sgl.h"

    Uint16 mode;

    void slColOffsetAUse( mode );

argument

    Uint16 mode - Screen affected by color offset value.

Return number

    void - returns nothing.

function

Sets the screen that is affected by the color offset value set by the function slColOffsetA .
In mode, NBG0ON , NBG1ON , NBG2ON , NBG3ON , RBG0ON , LNCLON , SPRON is entered.
When setting the drawing settings for multiple scroll planes at the same time, set the mode for each plane to "|" Please specify by connecting.

example

    slColOffsetA ( 35, 23, 12 );
                :
    slColOffsetAUse ( NBG0ON );

Note

When you execute the slColOffsetAUse and slColOffsetBUse functions, the slColOffsetOn function will also be executed at the same time, so The slColOffsetOn function does not need to be executed by the user.
