Thread: Random generation of a picturebox control....

Random number generators on finite state machines (i.e. computers) aren't random at all. Essentially your C compiler includes or builds at runtime a "book" of pseudo-random numbers. Whenever you ask for a random number, the computer refers to this book at a specific position, reads a number and then increments the position. The "specific position" this process starts from is what is set by srand(), literally "seeding the random number generator".

The statement:-

Code:

//correct form
srand((unsigned int)time(NULL));

Randomizes this position using the current system time, to give a further illusion of randomness.

I just wanted to say thanks again for the help, I think I have figured it out. I ditched the rand() function and went with the System::Random class. Hear is what I came up with.....

Code:

private: System::Void newGame_Menu(System::Object *  sender, System::EventArgs *  e)
		{	int Next( int maxValue);
			System::Random* m_Random = new System::Random();
			int newx = ship->Location.X; 
			int newy = ship->Location.Y; 
			Point newloc = Point(m_Random->Next(456),408); 
			ship->Location = newloc; 
		}

At first I could not figure out how to overload the next method to set a range but then it clicked.

Thanks
