hi there, I am trying to create a pong game but I can't get my paddles to move. This is my code, the error should be somewhere here:
void Movement()
{
bool GameOver = false;
while(!GameOver)
{
SDL_Event event;
while(SDL_PollEvent(&event))
{
switch(event.type)
{
case SDL_QUIT:
GameOver == true;
running = false;
break;
case SDL_KEYDOWN:
switch(event.key.keysym.sym)
{
case SDLK_UP:
if(paddle1Y > head1->h+20)
{
paddle1X--;
}
break;
case SDLK_DOWN:
if(paddle1Y < screen->h-10)
{
paddle1Y++;
}
break;
case SDLK_ESCAPE:
GameOver== true;
break;
}
break;
}
SDL_Flip(screen);
}
}
}
as soon as I call this function, input is ignoredm I don't know why. this is the full source if needed:
