Unity Engine

Hello, i have two script, in first script is character stats (in create character scene) and second script for health, mana, and load stats (in second scene with game). But i don’t know how to load stats in second scene. Can you help me? please?
Script for character stats:

static var HP : int = 0;

static var MP : int = 0;

static var STR : int = 0;

static var MND : int = 0;

static var DEF : int = 0;

static var ATK : int = 0;



var loadlevel : boolean = false;



var pocet = 15; //maximum presses on +



var pridat : boolean = true; //+ button

var odebrat : boolean = true; //- button



function Update(){

	if (loadlevel){

		Application.LoadLevel("Mapa2");

   		gameObject.Find("player").SendMessage("loadgame");

	}



	if (pocet == 0){

		pridat = false;

		odebrat = true;

	}

	else if(pocet >= 0){

		pridat = true;

		odebrat = true;

	}

	if (pocet == 15){

		pridat = true;

		odebrat = false;

	}

}



function OnGUI ()

{

   //(H-pos, V-pos, H-size, V-size)

   GUI.Label (Rect (5,5,100,25), "HP: " + HP);

PlayerPreft.SetInt(key,value) to set
PlayerPrefs.GetInt(key,defaultValue) to get

You don’t have to use int, just an example.

3

I read this example, but i don’t know how can use it

4

You’d only use PlayerPrefs for persistent storage. In this case, use DontDestroyOnLoad.

–Eric

5

And how use DontDestroyOnLoad?

6

http://unity3d.com/support/documentation/ScriptReference/Object.DontDestroyOnLoad.html

7

Unity - Scripting API: Object.DontDestroyOnLoad i know, but how to set in my script?

8

…in my second script is when you press “c” gui with stats is true

9

Exactly as it’s laid out in the example link in your post…

10

Yes, but what I write in brackets? DontDestroyOnLoad (what write here?);

11

I copy code from Unity - Scripting API: Object.DontDestroyOnLoad and put in my script but i need the the numbers from scene1 load in scene2. I don’t need buttons… from scene1 to scene2. I need only HP, MP, STR, ATK, DEF, INT numbers…

12

and therefore need playerprefs

13

Set player prefs is easy, but how get playerprefs in GUI.Text?

14

playerprefs are just your variables so you need to use there names. But you can make an script with only the stats vars and use DontDestroyOnLoad and you wont have the problem with GUI.

15

Yes, but I need only the values ​​recorded in the following script in a different scene. If I gave DontDestroyOnLoad so I keep it and it will be like in scene1, but I need the scene2 otherwise. I need to set and load values ​​in the GUI
