Displaying Keys

SDL Development
1

Hey,

Im using BFont to use a PNG font.

I want to do something really simple to test it out… so I tried displaying
the key being pressed.

Well, I can’t get it to work… it just crashes.

SDL_Event event;

int quit = 0;

while(!quit)
{

	while(SDL_PollEvent(&event))
	{
		switch(event.type)
		{
			case SDL_KEYDOWN:
				CenteredPutString(screen, 0, SDL_GetKeyName(event.key.keysm.sym);
				break;

			case SDL_QUIT:
				quit = 1;
				break;
		}

	}

}

Doesn’t work… just crashes… any suggestions?_________________________________________________________________

Are you sure SDL is being initialized properly?
You’re missing a ) on :
CenteredPutString(screen, 0, SDL_GetKeyName(event.key.keysm.sym);
but I assume that was just in the email… seing as it compiled for you.
I dont use BFont, but the SDL portion of the code is fine as far as I
can see.

Hi,

do you use a hardware surface. BFont has a bug there… Are you sure that the
characters within the returned string are in your image?

Btw. if you want to very easily create BFont fonts (bmp’s not png’s), take a
look here:
