Question

in class Snake I Have:

public Snake()
{
  snakeRec = new Rectangle[3];

  if(Form1.diffeasy = true)
  {
    colorid = "Green";
  }
  else if (Form1.diffnormal = true) 
  {
    colorid = "blue";
  }
  else if (Form1.diffhard = true) 
  {
    colorid = "purple";
  }
  else if (Form1.diffextreme = true)
  {
    colorid = "red";
  }


  Sbrush = new SolidBrush(Color.FromName(colorid)

Now the diffextreme, diffeasy,… are defined in Form1 as

bool diffeasy = false;
bool diffnormal = false;
bool diffhard = false;
bool diffextreme = false;

When a user chooses a difficulty, one of these is set to true.

My question is: How do I correctly access these booleans in the snake class?

Answer 1

Have accessor methods i.e. getter/setter methods defined in Form1 to access your fields of Form1 e.g. for diffeasy:

   boolean isDiffeasy (){
       return this.diffeasy;
   }

   void setDiffeasy (boolean diffeasy){
       this.diffeasy = diffeasy ;
   }

Use this methods of Form1 in Snake class as:

   if(form1.isDiffeasy()) {
       colorid = "Green";
    }

    ....
    form1.setDiffeasy (false);
