draw_get_alpha()
Returns: Real
This function returns the current value of the draw alpha, which
will range between 0 (fully transparent) and 1 (fully opaque). The
draw alpha affects the transparency of all draw functions, and can
be set with the draw_set_alpha function.
if draw_get_alpha() != 1
{
draw_set_alpha(1);
}
The above code first checks the current draw alpha and then if it is not set to 1 it sets it to 1.
