Thread: While thing

> while (right == true)
Like has been said already.

If right is false, if never gets into the loop.
If right is true, it never gets out of the loop.

Roughly speaking (5 mins reading the manual), I would try
- SDL_AddTimer to set a timer.
- In the timer callback function, call SDL_PushEvent to send a 'user' event, which in this context will mean that time has elapsed.

Replace the while (right == true) with if (right == true)
You'll now be getting periodic stimulus of the event queue (through the timer).

I'm not good at english. I don't really understand what you're saying. Show me some code.
EDIT:
What manual?

Everybody wants their stuff to work.

So why should you succeed in getting it to work? You need to put the effort into it. Playing around with tests is fine if you know what you're doing, but you have to be willing to invest in reading up on the library you're using.

The one from http://www.libsdl.org/docs.php
I mean, c'mon - this isn't rocket science.

That would be ironic if his game involves spaceships.

You know, if you say the title of this thread quickly it sounds sort of like this. </offtopic>

I almsot got it now! When i move the mouse and hold down left or right, it moves! I think it is because the mouse gives the program a new event. Right? So if i would like to do this without moving the mouse. How should i do?

Code:

Code:

    //While the user hasn't quit
    while( quit == false )
    {  
        //If there's an event to handle
        while (SDL_PollEvent(&event))
        {
              if (event.type == SDL_KEYDOWN)
              {
                                switch(event.key.keysym.sym)
                                {
                                                               case SDLK_LEFT:
                                                                     left = true;
                                                                     break;
                                                                     
                                                               case SDLK_RIGHT:
                                                                     right = true;
                                                                     break;
                                                                     
                                                               case SDLK_ESCAPE:
                                                                    quit = true;
                                                                    break;
               }                 }
               
               if (event.type == SDL_KEYUP)

                                                                     apply_surface( x, y, piece, screen );

            //If the user has Xed out the window
            if( event.type == SDL_QUIT )
            {

                quit = true;
            }
    
        //Update the screen
        if( SDL_Flip( screen ) == -1 )
        {
            return 1;    
        }
    }

Put the if(right == true) (by the way, why don't you simply use if(right) ?) outside the while(SDL_PollEvent...)
