G2_SetBlendBrightnessExt

C Specification

#include <nitro/gx/g2.h>
void G2_SetBlendBrightnessExt(
int plane1 /* GXBlendPlaneMask */,
int plane2 /* GXBlendPlaneMask */,
int ev1,
int ev2,
int brightness
);

Arguments

plane1 Selects the plane where the brightness will be changed (result of a logical OR with the GXBlendPlaneMask type values)
plane2 Selects the screen where alpha-blending is performed on the translucent OBJ, bitmap OBJ, and 3D screen.
ev1   alpha-blending coefficient for the translucent OBJ, bitmap OBJ, and 3D screen. ev1 ≤ 31)
ev2   alpha-blending coefficient for plane2. ev2 ≤ 31)
brightness Specifies the coefficient to change the brightness of plane1 (-16 ≤ brightness ≤ 16)

Return Values

None.

Description

This function changes the brightness of the screen specified by plane1. If brightness is positive, the brightness increases; if it is negative, the brightness decreases. Furthermore, alpha-blending is performed on the translucent OBJ, bitmap OBJ, 3D screen, and the screen specified by plane2. See G2_SetBlendAlpha for details on the GXBlendPlaneMask type.
