Player_SpaceShip_IP.cs will deal with the player's health/lives management, but
when a player runs out of lives, it calls the PlayerDied() function here so that the game
controller can decide whether or not the game is actually over. If this is a single-player
game, the game can end right after this function call, but if it is a two-player game, we
need to make sure that both players have lost all their lives before ending the game
completely:
public void PlayerDied(int whichID)
{
The ID of the player with no lives left is passed in as a parameter named whichID. This
is used to set player1Dead or player2Dead to true, depending on the ID number:
if(whichID==1)
player1Dead=true;
if(whichID==2)
player2Dead=true;
This part of the code checks to see whether this is a two-player game and, if so, tells
the UIControl script to show the game-over message. A call to Exit() is scheduled by an
Invoke call 5 s later:
if(player1Dead && player2Dead && totalPlayers>1)
{
// both players are dead, so end the game
UIControl.ShowGameOver();
Invoke ("Exit",5);
When totalPlayers is 1, this must be a single-player game, so there is only a need for
one call to happen to this function for it to show the game-over message and end the game:
} else if(totalPlayers==1)
{
// this is a single-player game, so just end the game now
// both players are dead, so end the game
UIControl.ShowGameOver();
Invoke ("Exit",5);
}
}
