        b[i].move();
        while (b[i].getX()==temp.getX() && b[i].getY()==temp.getY())
            b[i].move();
        
        //cout<<b[i].getX()<<","<<b[i].getY()<<endl;
    }


this code loops through an array of size=size, initializing each instance of the array with random x and y values. these instances move randomly in one of 8 possible directions. Following is the class function "bug::move()"

void bug::move(){

            int xMove, yMove, bMove;
            
            xMove=rand()%3;
            yMove=rand()%3;
            
            if (alive=true){
           
                {
                    if (xMove==0 && x-1>0)
                        x--;
                    if (xMove==2 && x+1<maxX)
                        x++;
                    else
                        x=x;
                }
           
           
                {
                    if (yMove==0 && y-1>0)
                        y--;
                    if (yMove==2 && y+1<maxY)
                        y++;
                    else
                        y=y;
                }
           
                
            }


this code works pretty well (the bugs stay in valid range), but i keep getting instances in which a bug will not move (by random chance, the values just dont change). I'm not detecting, logically, what is causing this. that is why i put in a while loop after b[i].move() to move again if the values are both the same. Which also poses a problem of my bug moving more than once (i have no code to reset the values to their previous state, i believe that re-initializing them with random values isnt an option).

a) they won't move if they try to move into a wall
b) they won't move if both xMove and yMove will be 1, which has 1/9 chance of happening.

                }
           
                
            }



should i revise the method "bug::move" like this?

correct me if i'm wrong but shouldn't it be if(alive==true)?
