Simple save/load scripting for multi level iOS game.

I understand that I just stated that I had trouble and didn't ask a question. Sorry. Basically, my question is, How do I write a save and a load script. You gave me some ideas in your answer but they don't seem to be working for me. Here is my script for when the player touches the save icon on the screen:

function On$$anonymous$$ouseUp () { // This is for saving the level that the first person character is on. PlayerPrefs.SetInt("SavedLevel", Application.loadedLevel); // These three are the location as to where the first person character is on the above level. PlayerPrefs.SetFloat("PlayerX", playerTransform.position.x); PlayerPrefs.SetFloat("PlayerY", playerTransform.position.y); PlayerPrefs.SetFloat("PlayerZ", playerTransform.position.z); // This is just a dialog to be sure that I touched the save button. Debug.Log ("I touched the save icon"); }

And here is the script that I am trying to use for the Load button on the main menu when the player starts the game:

var touchRange: float = 100.0f;

function Update () { for (var touch : Touch in Input.touches) { if (touch.phase == TouchPhase.Began) { //Here you have the touch's position so, This is where you have to create a ray using ScreenPointToRay var userRay = Camera.main.ScreenPointToRay(touch.position); //This is to store the RayCasting results var info : RaycastHit; //[Physics.RayCast][2] actually casts the ray and if it returns true it "Hit" something if(Physics.Raycast(userRay, info, touchRange)) { //This tells us if the thing it hit was a "Door". if(info.transform.CompareTag("InstructionsTag")) { // This is where I am putting the change level info if (PlayerPrefs.Has$$anonymous$$ey("SavedLevel")) Application.LoadLevel(PlayerPrefs.GetInt("SavedLevel")); else //I'm using the following just in case the player taps the load button and nothing had been saved. Application.LoadLevel ("Level1"); Debug.Log ("I touched the Instructions Button!"); } } } } }

Could you please tell me what I am doing wrong and how I may fix it so that I may have a simple save and load for my iOS game.?

Thanks so much!!! I really appreciate any help you may offer.

$$anonymous$$,

I don't have time at the moment to look at your code, but a quick note:

playerTransform is something you need to define - it tells the code where to look to find the player position, rotation, etc. Perhaps define it in your Start function, something like this:

var playerTransform : Transform;

 function Start()
 {
   //here is where you define the transform for the player
   //look at the various find functions here (http://unity3d.com/support/documentation/ScriptReference/GameObject.html)
   //and choose the one that works best for your case

   //this should work if your player GameObject / Transform is name 'Player'
   playerTransform = GameObject.Find("Player");
 }

Apologies if that doesn't work out of the box - I'm a C# programmer and don't often work in JS.

alternatively, if you put the script within the actual player (attach it as a component), then you can just use 'transform' - that always means 'the transform I'm attached to', so for instance

 PlayerPrefs.SetFloat("PlayerX", transform.position.x);

Here's a bit of reading on transforms: http://unity3d.com/support/documentation/Components/class-Transform.html http://unity3d.com/support/documentation/ScriptReference/Transform.html
