Time for action — creating the atom elements


At the start of a game, or when you want to reset the game field, you will call this method to set up a new tile set:

  1. 1. The new method inside the game class will be named CreateAtomElements.

    Method CreateAtomElements:Int()
    
  2. 2. We want to randomize the grid setup. For this we will seed the random number generator with the value of a call to Millisecs.

    Seed = Millisecs()
    
  3. 3. The distance from a collision circle to the center of an atom will be 23 pixels and stored inside a local variable.

    Local cd:Int = 23
    
  4. 4. Now, we need a grid of 8 x 11 elements. Start two For loops for this purpose.

    For Local y:Int = 1 To 11
    For Local x:Int = 1 To 8
    
  5. 5. Next, we determine randomly in the range of 0 to 3 the kind of element which represents the different kinds of atom connectors.

    Local ek:Int = (Rnd(0,3)+0.4)
    
  6. 6. As we do not want the game to go on forever, we modify the ek value to a different one. This depends on another random number call with a range from 0 to...
