Previous room for 1 person game.

[td]

I trying to add
character[EGO].PreviousRoom;
function when some keycode is pressed (403 for example) . But my character is hide (therefore i haven't character) coz i make 1 person game. So the code must be:

if (keycode==403) ....

And then???

The player character still exists, even if they are invisible, so you can use player.PreviousRoom.

[Khris]

player.PreviousRoom only returns the previous room's number; you probably want to use

Code: ags

if (keycode==403) player.ChangeRoom(player.PreviousRoom);

rtfm...

Thanks Khris. That Is that!

EDIT:
Yes. But in some moments in my game PreviousRoom function must be blocked (player can't back).
How can i blocked this, Khris?

You could add an on_key_press function to those rooms, using ClaimEvent() to block the main one:

Code: ags

// Room script
function on_key_press (int keycode) {
  if (keycode == 403) ClaimEvent();
}

Or, you could create a Custom Property that determines whether or not backtracking is allowed. E.g., create a boolean property called 'AllowBack', and change the Global on_key_press condition to:

Code: ags

if (keycode==403 && GetRoomProperty("AllowBack") == true) player.ChangeRoom(player.PreviousRoom);

If it's just at specific times you want backtracking disabled (e.g. the player enters the room and the door locks behind them - can't go back untill they unlock it), just create a script variable, and have on_key_press check that instead/as well.

Line
  if (keycode==380) player.ChangeRoom(player.PreviousRoom);
is work,but here is a problem i meeted:
For example i visited rooms: 1>2>3>4
If i press button (380) i retuned : 4>3>4>3 etc.  I thought it must be 4>3>2>1 and i need right this.

How can i change this?

You could try:

if ((keycode == 380) && (player.Room > 1)) player.ChangeRoom(player.Room - 1);
