Creating Level-to-Level communication (scripts)

Unity Engine
1

Must be the early morning or something, but I can’t seem to come up with a way that my Door trigger will go to the loading screen, remember what level I want to load, and when the second level is loaded, load the level… I’m probably thinking a bit too far, but I can’t seem to wrap how I want to get this right:

Note: Don’t worry about the talkMode and talking variables, I just ripped them from another code that I made as it’s doing nearly the same exact thing.

var IconTexture : Transform;

private var stayInTrigger = 0.0;
private var talkMode = false;
static var talking = false;

private var TextureShowing = false;

function Start()
{	
	IconTexture = Instantiate (IconTexture, transform.position, transform.rotation);
}

function Update ()
{
if (TextureShowing == true)
	{
		IconTexture.GetComponentInChildren(MeshRenderer).enabled = true;
	}
	else
	{
		IconTexture.GetComponentInChildren(MeshRenderer).enabled = false;
	}

}

function OnTriggerEnter(player : Collider)
{
if(player.CompareTag("Player"))
stayInTrigger = Time.time;
}

function OnTriggerStay(player : Collider)
{
if(player.CompareTag("Player"))
{
if (Time.time > stayInTrigger + 1.00)
	{
		talking = true;	
		TextureShowing = true;
	}
		
if (Input.GetButton ("Jump")  talkMode == false  talking == true)
	{
		talkMode = true;
		MyWalkerController.isControllable = false;
		talkDelay = Time.time;
	}
}
}

function OnTriggerExit(player : Collider)
{
if(player.CompareTag("Player"))
{
talking = false;
TextureShowing = false;
}
}

The line

Is where I’m planning on loading my “loadingScreen” level. However, I want to have a variable named “levelToLoad” (which needs to be turned into a static var so my loading screen can pick it up) And then set that variable to whatever level I want (so if I… lets say set it to my Test level for the time being, I can). The Loading Screen will pick up this variable (ThisScript.levelToLoad), load the level in the background and when the level is 100% loaded, load the level.

After the level is loaded, it’s going to destroy that extra Door object as it no longer needs to hold onto that variable and is of no use, so once the level loads my other door object (to go back outside) will delete the extra door object (it’ll search for it, and if it’s there it’ll delete it, that’s simple though).

That’s what I’m going for, but the main problem that I have is, I don’t own Unity Pro, which means I can’t use the asynchronous load function which many of the loading screen topics suggest. I can possibly use “LoadInBackground” But either way I’m not wrapping my head around how I’m going to set it up.

I think PlayerPrefs would work fine, but I didnt look at all of your post.

I’m gonna bump this over the night. Not only would PlayerPrefs not help me, I fail to even see how it would remotely help me, it has absolutely nothing to do with scripts talking to each other between levels/scenes. I just want to get it where a variable tells which level to load, but before it loads that level it goes through the loading screen.

—Script has Level X set as the level to load via a variable
Which then goes to —
—ONE SINGLE LOADING SCREEN (so I don’t need a level/scene for each time I need to load a new level) === The script in this scene will pick up the variable from the first script, tell which level I want loaded in the background. This way, whenever I’m loading a level it will be the same scene no matter what. I don’t want to have 50 different loading screens, each with different levels to load; that’s just a waste of resources, time, and memory.
Which will then —
Load the level I had told the script in the previous level to load (I’m outside, load the indoors level), the variable from the first level gets sent to the Loading screen to tell it which level to load, and then load said level.

Once again I -cannot- use Asynchronous load as it is a Unity Pro function (which I don’t have the funds to acquire)
