Code: [Select]


moveHero(dave.location,dave.location = dave.location -= X_TILES);


Don't do that. The C++ standards does not specify the order of evaluation for function arguments.

Thanks for the info.  Fixing that now!

General / Resolved ( I think )

This seems to be a much better way to accomplish what I was attempting.

Code: [Select]


   while (window.PollEvent(event)) {
      processEvents(window, event);
      switch (event.Type) {
        case sf::Event::KeyReleased:
        if (event.Key.Code == sf::Keyboard::Up) {
          moveHero(dave.location,dave.location = dave.location -= X_TILES);
          break;
        }
        if (event.Key.Code == sf::Keyboard::Down) {
          moveHero(dave.location,dave.location = dave.location += X_TILES);
          break;
        }
        if (event.Key.Code == sf::Keyboard::Left) {
          moveHero(dave.location,dave.location = dave.location -= 1);
          break;
        }
        if (event.Key.Code == sf::Keyboard::Right) {
          moveHero(dave.location,dave.location = dave.location += 1);
          break;
        }
        default:
        break;
      }
    }


Thanks

General / Restricting Sprite Movement in Loop

« on: January 06, 2012, 11:16:47 pm »

I am using SFML 2.0...

I am confident that there is a better way but I have been banging my head on the wall for hours here.  

Basically, I have a character (sprite) that needs to move in an array but only 1 time per key press.  The code shows up and down "movement".  Left and Right would need to be additionally coded.

Here is what I have cobbled together but I know that this can't be "right":

Code: [Select]



bool keyUp = false;
bool keyDown = false;

while (window.IsOpened()) {
  while (window.PollEvent(event)) {
    if ((keyUp == false)&& sf::Keyboard::IsKeyPressed(sf::Keyboard::Up))) {
      keyUp = true;
      moveHero(dave.location,dave.location = dave.location -= X_TILES);
    }
    if ((keyUp == true)&&(!sf::Keyboard::IsKeyPressed(sf::Keyboard::Up)))
        keyUp = false;
      if ((keyDown == false)&&(sf::Keyboard::IsKeyPressed(sf::Keyboard::Down))) {
          keyDown = true;
          moveHero(dave.location,dave.location = dave.location += X_TILES);
      }
      if ((keyDown == true)&&(!sf::Keyboard::IsKeyPressed(sf::Keyboard::Down)))
          keyDown = false;
    }
  }
}


Anyone have a moment to help a noob out?

Thanks

Graphics / Drawing Multiple Sprites

« on: January 02, 2012, 10:07:51 pm »

Thanks Mario.  That is where the error was:

Code: [Select]


  if(!texture.LoadFromFile("cobblestone.png"))
    // return error
    for(int i = 0; i < sizeof(sprite) / sizeof(sprite[0]); i++) {
      sprite[i].SetTexture(texture);
    }


The version that was not working is was using

Code: [Select]


 i < sizeof(sprite);

 :roll:

I am going to implement your other suggestions now.  Thanks again!

Graphics / Drawing Multiple Sprites

« on: January 02, 2012, 09:18:23 pm »

Hello.  I am new to SFML and using version 2.  I am able to create and texture a sprite but when I try to create any more than 1,  I get an segmentation fault.  Here is how I am trying to display the sprites:

Code: [Select]


int i, x, tile = 0;
  for(i = 0; i < WINDOW_W; i += TILE_W) {
    for(x = 0; x < WINDOW_H; x += TILE_H) {
      sprite[tile].SetPosition(i, x);
      window.Draw(sprite[tile]);
    }
  }


Thank you for any suggestions!
