*** can't find file [image\title\titlebtn1.png] ***
The above warning message mainly causes the crash.
It's because image\title\titlebtn1.png is not there.
In current version, the code is:
if ( buf[0] != '\0' ){
btndef_info.setImageName( buf );
parseTaggedString( &btndef_info );
btndef_info.trans_mode = AnimationInfo::TRANS_COPY;
setupAnimationInfo( &btndef_info );
SDL_SetAlpha( btndef_info.image_surface, DEFAULT_BLIT_FLAG,
SDL_ALPHA_OPAQUE );
}
In this case, buf = "image\title\titlebtn1.png" so btndef_info.setImageName()
and following calls will result btndef_info.image_surface to be NULL because
it's really not exists.
And then SDL_SetAlpha crash because it's NULL.
In Haeleth's version, the code is
if ( buf[0] != '\0' ){
btndef_info.setImageName( buf );
parseTaggedString( &btndef_info );
btndef_info.trans_mode = AnimationInfo::TRANS_COPY;
setupAnimationInfo( &btndef_info );
#ifdef RCA_SCALE
if (btndef_info.image_surface
&& (scr_stretch_x > 1.0 || scr_stretch_y > 1.0 )) {
// Scale and reposition buttons if screen is bigger than game
SDL_Surface* src = btndef_info.image_surface;
SDL_PixelFormat *fmt = src->format;
SDL_Surface* dst = SDL_CreateRGBSurface( SDL_SWSURFACE,
scr_stretch_x*src->w,
scr_stretch_y*src->h,
fmt->BitsPerPixel, fmt
resizeSurface( src, dst );
btndef_info.image_surface = dst;
btndef_info.pos.w *= scr_stretch_x;
btndef_info.pos.h *= scr_stretch_y;
SDL_FreeSurface( src );
}
if (btndef_info.image_surface)
#endif
SDL_SetAlpha( btndef_info.image_surface, DEFAULT_BLIT_FLAG,
SDL_ALPHA_OPAQUE );
} else btntime_value = 0; //Mion - clear the btn wait time
So when RCA_SCALE is defined, it checks btndef_info.image_surface before
calls to SDL_SetAlpha() which won't cause the crash.
