# G2_ChangeBlendAlpha

## Syntax

      #include <nitro/gx/g2.h>

      void G2_ChangeBlendAlpha(int ev1, int ev2);

## Arguments

ev1 | Alpha-blending coefficient for the first target screen (0 ≤ ev1 ≤ 31)
ev2 | Alpha-blending coefficient for the second target screen (0 ≤ ev2 ≤ 31)

## Return Values

None.

## Description

Sets only the alpha-blending coefficient.
If the values of ev1 and ev2 are greater than 16, the alpha-blending coefficient that is actually set is 16.
