[EO 2.0] Whats is this code?

[da_gad_pader]

can someone explain what's the use of this codes?

```
' stuffs
Public Const HalfX As Integer = ((MAX_MAPX + 1) / 2) * PIC_X
Public Const HalfY As Integer = ((MAX_MAPY + 1) / 2) * PIC_Y
Public Const ScreenX As Integer = (MAX_MAPX + 1) * PIC_X
Public Const ScreenY As Integer = (MAX_MAPY + 1) * PIC_Y
Public Const StartXValue As Integer = ((MAX_MAPX + 1) / 2)
Public Const StartYValue As Integer = ((MAX_MAPY + 1) / 2)
Public Const EndXValue As Integer = (MAX_MAPX + 1) + 1
Public Const EndYValue As Integer = (MAX_MAPY + 1) + 1
Public Const Half_PIC_X As Integer = PIC_X / 2
Public Const Half_PIC_Y As Integer = PIC_Y / 2

```

It's basically defining the variable.

Look at the last two.
Half_PIC_X = PIC_X / 2
Half_PIC_Y = PIC_Y / 2

Try deleting it and see how fun your game is with no play screen. Those are all the screen calculations.
