void G2_SetBlendBrightnessExt(
int plane1 /* GXBlendPlaneMask */,
int plane2 /* GXBlendPlaneMask */,
int ev1,
int ev2,
int brightness
);
This function changes the brightness of the screen specified by plane1. If brightness is positive, the brightness increases; if brightness 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 information on the GXBlendPlaneMask type.
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. |
ev2 |
alpha-blending coefficient for plane2. |
brightness |
Specifies the coefficient to change the brightness of plane1 (-16 <= brightness <= 16) |
None.
