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:

The new method inside the game class will be named CreateAtomElements.
```
Method CreateAtomElements:Int()
```
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()
```
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
```
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
```
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)
```
