Graphics / sprite being drawn twice on top of each other?

« on: July 08, 2012, 02:26:00 pm »

Hi all, I have a strange problem where in my bomberman type game I'm making, when you lay a bomb, it appears very rough around the edges. Testing in photoshop it looks like the png is being layered on top of its self twice on the window.draw(*bomb). I can tell this because the flame which is semi transparent is very dark compared to just manually placing the bomb on the field. (See pic please - I've enlarged this to make it clearer).
Has anyone come across this before and/or could suggest why this might be happening? I have tested and know only 1 bomb is being layed when space bar is pressed, so why the double texture?

Note the left bomb is a sprite I manually created and placed , the right one is one "layed" in the game by pressing spacebar, and as I say it is only 1 object...

Graphics / Texture won't display when loaded from within a class?

« on: July 07, 2012, 06:05:48 pm »

Hello all, 

Total noobie here but Im trying to create a simple game. I want to create a bomb object and everything is fine if I set the bomb up from within the main() loop, but if I try to make a bomb class then create a new bomb from this class, the texture no longer loads, I just get a white square instead. Can anyone help see why please?
Also can I pass a sf::IntRect() over the the class instead of having to pass over 4 individual ints? I tried changing the bomb class to get sf::IntRect textureRect and passing sf::IntRect(0,0,32,32) in the call but I just could not get it to work, so I am not sure if this is possible?

Main worry is the lack of texture anyway, like I say if I have the bomb created in main it shows the png bomb just fine, any suggestions most appreciated thanks. 

Code so far:

call top create new bomb instance in main()

Bomb bomb(0,0,32,32,0,0,64,64,160,160); // would rather pass some IntRects so neaten this up!
 

In bomb class (bomb.h):

public:
  Bomb(int texureRectX, int textureRectY, int textureRectSizeX, int textureRectSizeY, int collisionRectX, int collisionRectY, int collisionRectSizeX, int collisionRectSizeY, int posX, int posY )
  {
         this->setTextureRect(sf::IntRect(0,0,32,32));
         this->setRelativeCollider(sf::IntRect(0,0,64,64));
         this->setPosition(160, 160);
         sf::Texture bombChar;
         bombChar.loadFromFile("images/bomb.png");
         this->setTexture(bombChar);
  };
