lay()
{
int done=0;
while(done == 0)
{
SDL_Event *event;
while(SDL_PollEvent(event))
{
if (event->type == SDL_QUIT) done =1;
}
DrawScene();
}
}
Any Ideas???
Help with SDL Error Please!
Author
I know this is going to be very simple for someone but I cannot set the problem for myself.
I can compile the code below and it compiles without errors or warningings, but when I run it I get the error:
"Run-Time check failure #3 The variable event is being used without being defined"
void CTWGame:lay()
{
int done=0;
while(done == 0)
{
SDL_Event *event;
while(SDL_PollEvent(event))
{
if (event->type == SDL_QUIT) done =1;
}
DrawScene();
}
}

The way you''re using SDL_PollEvent is non kosher. Either pass it the address of a valid event structure, or pass it null. i.e.:
SDL_Event event;
while (SDL_PollEvent(&event)) {
SDL_Event event;
while (SDL_PollEvent(&event)) {
SDL_Event *event;
while(SDL_PollEvent(event))
needs to be
SDL_Event event;
while(SDL_PollEvent(&event))
while(SDL_PollEvent(event))
needs to be
SDL_Event event;
while(SDL_PollEvent(&event))

I have tried both of the above and now come back with errors at compile time. Perhaps I am being a bit retarded here.
I now get
"SDL_Event" does not have an overloaded member operator ->
left of''->type> must point to class/struct/union
I know I am missing something here.

You can use event.type instead of event->type.
Or, if you insist on using a pointer the whole time, you can leave it the way you had it before and change the beginning to
Zorx (a Puzzle Bobble clone)
Discontinuity (an animation system for POV-Ray)

Thanks Clum 
Thats sorted the problem.
I dont envy you with Java, I have never managed to get on with, but perhaps one day I will return to it.

Check out what line you get that error at. When the object is a pointer, you use the -> operator, if not you use the . operator. Try changing event->type into event.type
