Time for action — detailing the Render event

Ok, let's start with detailing the OnRender method.

  1. First, before we render anything, we will clear the screen with a nice blue color.
    Method OnRender:Int()
Cls(0, 0, 50)
  2. Next, we will call different render methods, depending on the mode the game is in.
    Select gameMode
Case gmMenu, gmGameOver
RenderGame()
RenderMenu()
Case gmPlay
RenderGame()
End
Return True
End
  3. Add the RenderMenu method. Inside, we will draw different text, depending on the mode the game is in.
    Method RenderMenu:Int()
Local cd:Int = Rnd(0,100)
If gameMode = gmMenu
SetColor(255-cd,0,0)
Local s1:String = "*** Rocket Commander ***"
DrawText(s1, cWidth/2, cHeight/2 - 48, 0.5, 0.0)
SetColor(255,255,255)
Local s2:String = "Press P to start the game"
DrawText(s2, cWidth/2, cHeight/2, 0.5, 0.0)
Local s3:String = "Press A Or S To fire the rockets"
DrawText(s3, cWidth/2, cHeight/2 + 48, 0.5, 0.0)
Else
SetColor(255-cd, 0, 0)
Local s1:String = "*** GAME OVER ***"
DrawText(s1, cWidth/2, cHeight/2 - 24, 0.5, 0.0)
SetColor(255,255,255)
Local s2:String = "Press R to restart the game"
DrawText(s2, cWidth/2, cHeight/2 + 24, 0.5, 0.0)
Return True
Endif
Return True
End
  4. Add the body of the RenderGame method. We will fill it with details later.
    Method RenderGame:Int()
Return True
End

It's better to be safe than sorry. Save the file, so your changes are not destroyed if your computer shuts down for any reason.

What just happened?

As you can see, we have slowly acquired the skeleton of our game. Of course, no objects so far, but the basic structure is almost set.
