I am working through the SDL tutorials over at http://lazyfoo.net/SDL_tutorials/index.php and I'm stuck on tutorial 8 where I'm working with key presses.
I'm using the following code:
//Our Main application loop
while(!quit){
if(SDL_PollEvent(&curEvents)){
if(curEvents.type == SDL_QUIT){
quit = true;
}
//If a key was pressed
if( curEvents.type == SDL_KEYDOWN )
{
//Set the proper message surface
switch( curEvents.key.keysym.sym )
{
case SDLK_UP:
message = upMessage;
break;
case SDLK_DOWN:
message = downMessage;
break;
case SDLK_LEFT:
message = leftMessage;
break;
case SDLK_RIGHT:
message = rightMessage; break;
default:
message = TTF_RenderText_Solid(font, "Unknown Key", textColor);
break;
}
}
}
if( message != NULL )
{
//Apply the background to the screen
applySurface( 0, 0, background, screen );
//Apply the message centered on the screen
applySurface( ( SCREEN_WIDTH - message->w ) / 2, ( SCREEN_HEIGHT - message->h ) / 2, message, screen );
//Null the surface pointer
message = NULL;
}
//Update the screen
if( SDL_Flip( screen ) == -1 )
{
return 1;
}
}
Where works fine, the default case is reached, for everything BUT pressing the arrow keys. I was wondering if someone could spot what I'm doing wrong.
