Time for action — modifying the menu update process

Head to the UpdateMenu method and add the following lines:
```
If gameMode = gmMenu
'we will add code here later
```
Check if the P key was hit.
```
If KeyHit(KEY_P) Then
```
Set game mode to gmPlay, and also seed the random number generator with the current time (in milliseconds) from when this game is active.
```
gameMode = gmPlay
'Set random number generator
Seed = Millisecs()
Endif
Else
'Code that runs when gameMode = gmGameOver
```
Check if the R key is hit after one game is over.
```
If KeyHit(KEY_R) Then
```
Remove all cities and rocket launchers.
```
RemoveCities()
RemoveLaunchers()
```

Set up the game again, and set the game mode to gmPlay.

SetupGame()
gameMode = gmPlay
Endif
Endif
Return True
End

Good, now we can leave this part of code and forget about it. We can start the game now or restart it.

Just like the cities, we want to see our launchers in the game. That is why we need to enhance the RenderGame method.
