PlayerPrefs.SetInt = PlayerPos x,y,z

Unity Engine

Hi.
thanks for any help !

i need when the player press a mouse button
save the player position x,y,z

then when press a second button
go to saved position

I already have this code but not working:

function save_position () {

PlayerPrefs.SetInt("PlayerPosX", newSpawnPoint.transform.position.x);
PlayerPrefs.SetInt("PlayerPosY", newSpawnPoint.transform.position.y);
PlayerPrefs.SetInt("PlayerPosZ", newSpawnPoint.transform.position.z);
}


function relocation () {

player_position_spawn = PlayerPrefs.GetInt("PlayerPosX");
my_player.transform.position = player_position_spawn.position;

player_position_spawn = PlayerPrefs.GetInt("PlayerPosY");
my_player.transform.position = player_position_spawn.position;

player_position_spawn = PlayerPrefs.GetInt("PlayerPosZ");
my_player.transform.position = player_position_spawn.position;
}

the error message when try to relocate player:
(picture below)
thanks for any help on this

Try puting the script into Standard Assets folder and see if it works.

Without knowing what type your variables are this could be wrong but:

This line
PlayerPrefs.SetInt(“PlayerPosX”, newSpawnPoint.transform.position.x);

Would be saving just a number like 20 (I would have thought a float would be better unless the player does only move by whole numbers)

Then you get this number with
player_position_spawn = PlayerPrefs.GetInt(“PlayerPosX”);

which would result in player_position_spawn = 20

Then you try and use this variable to set the players new position x
my_player.transform.position = player_position_spawn.position;

Why did you stick .position onto the end of the variable player_position_spawn.position it doesnt seem right.
I would have thought you need something like this:

function relocation () {

player_position_spawn_X = PlayerPrefs.GetInt("PlayerPosX");
my_player.transform.position.x = player_position_spawn_X;

player_position_spawn_Y = PlayerPrefs.GetInt("PlayerPosY");
my_player.transform.position.y = player_position_spawn_Y;

player_position_spawn_Z = PlayerPrefs.GetInt("PlayerPosZ");
my_player.transform.position.z = player_position_spawn_Z;
}

But as I said without the variable types I could be wrong

There are a few obvious problems…

First, a “position” is a Vector3. The x, y, and z components of a Vector3 are of type float, not int. So, you’re probably going to want to use PlayerPrefs.SetFloat and PlayerPrefs.GetFloat instead of the Get/SetInt methods you’re using now.

Next, when you retrieve the stored vaues, you’re retrieving a simple, scalar value - not a “position” object. Assuming you make the above-mentioned change, the retrieved value will be a simple float.

So, to use it, you need to assign it to the appropriate member of the position object. So, something like this:

float xVal = PlayerPrefs.GetFloat("PlayerPosX");
my_player.transform.position.x = xVal;

Note, I’m a C# user, but I think the above syntax is OK in US…

Not sure I understand the problem. Why not just…

  • Load the saved level
  • Restore the player’s position to the saved position using (something like) the above code?

So, just set the player’s position to the loaded x, y, and z values…

ok …
thanks so much for all your invaluable help…

i try first and reload the saved level…
but when try to re-locate the last player position of the player is not working…

i think my problem is how tell to unity3d who will relocate…

i explain :

when you are on level 3 for example …
and save the level and location

then quit

then reload a resume game …

but the problem is when try to reload the player position

how can I tell unity3d who is newSpawnPoint ?
because you are on menu scene calling level 3, and … on menu scene you dont have a player
got it ?

any idea please ?
