Time for action — rendering the game field

Which elements will be rendered in the game?

The player paddle
Enemy paddle #1
Enemy paddle #2
The ball
A wall at the top
A wall at the bottom
A middle line

The last three elements can be grouped together as a background. So let us do just that:

Now, insert the drawing routines for the background graphics. Between the OnUpdate method and the OnRender method, create a new method called DrawPlayField.

Method OnUpdate:Int()
Return True
End
Method DrawPlayField:Int()
'Draw the top wall with a rectangle
DrawRect(0,0,640,5)
'Botton wall
DrawRect(0,475,640,5)
'Middle line, 13 pieces, each 10 pixel long
For Local i:= 5 To 465 Step 20
DrawRect(318,i,4,10)
Next
Return True
End
Method OnRender:Int()

We need to modify the OnRender method now, so that the new DrawPlayField method can be called.

Method OnRender:Int()
Cls 'Clear the canvas each frame
DrawPlayField() 'this call draws the background
Return True
End

Like before, save your script and test it, to see if it runs fine. For going further with a pre-built script, you can use the Pongo_03.Monkey file. You should now see a screen that looks as follows:
