    Problem when rendering my game.

    Hello I am making a simple snake game with images using that:

    Code:
      private void rendering()        {
    
    
                while (true)
                {
                
                    if (pbCanvas.InvokeRequired)
                    {
                        //pbCanvas.Refresh();
                        pbCanvas.Invoke(new MethodInvoker(delegate { Refresh(); })); //delete the images that where on the canvas(picture box).
                        render(); //render the snake and the food.
                        //tryed without threading but it's the same.
                    }
                    
                }
                   
                
                }
    And at start:
    Code:
    Thread th = new Thread(rendering);
                th.Start();
    But the snake always flusing, i mean that he does show up but then he just disappear and show up agian. Dont know how to explain it properly (Same the food).

    I'm assuming your canvas is some kind of control or a Form. You need to set the DoubleBuffered property on this control/Form to True to prevent flicker. Also, don't delete the previous frame when rendering a new one. Simply draw the new frame over the old one.
