Drawing New Graphics
« on: January 31, 2017, 02:22:07 am »
I am creating a simple rock paper scissors game. When the player wins or loses, the screen should clear and the words loser or wins appears on the screen. I am able to draw the rock paper scissors; however, it will not clear the screen and draw the new texts. Instead the debugger breaks the program. I am not sure how to fix this issue.

Since you should be clearing and drawing on every cycle, to draw something different, continue clearing but draw different things.

Instead the debugger breaks the program. I am not sure how to fix this issue.
It doesn't clear but it crashes? What does the debugger say/do? Which issue?

My render function looks like this:
   texture.clear();
   if (win == true)
   {
      texture.draw(_results.loadText("Win"));
   }
   else if (lose == true)
   {
      texture.draw(_results.loadText("Loser"));
   }
   else
   {

      texture.draw(_scissors.scisssorsdraw());
      texture.draw(_rock.rockDraw());
      texture.draw(_paper.paperDraw());
   }
      texture.display();
      
      _render.clear();
      sf::Sprite sprite(texture.getTexture());

      _render.draw(sprite);
      _render.display();


The debugger gives this
+      this   0x006ff1a0 {_render={...} _mouse={...} _events={type=MouseButtonPressed (9) size={width=0 height=305 } ...} ...}   MainGame *
+      sprite   {m_vertices=0x006fdf34 {{position={x=-107374176. y=-107374176. } color={r=204 'Ì' g=204 'Ì' b=204 'Ì' ...} ...}, ...} ...}   sf::Sprite

It breaks with an error at this point I do not understand right after trying to draw the text.  I am thinking it is the redrawing. Maybe it is the text code. I am including the loading text function that I created.
sf::Text& WinLost::loadText(std::string messange)
 {
   
   
   
   
   
   text.setFont(loadFont("Fonts/chintzy.ttf"));
   
   
   text.setString(messange);
   text.setPosition(80, 90);
   text.setCharacterSize(24);
   
   return text;
}

The font needs to exist even after the function ends. You should store it elsewhere and pass it into (make available to) this function.
