Problem with static variables

Question

Hi

I'm creating a game with different levels. I have a Main Menu and also a level selection menu. I also have 2 scripts. I'd like to know how it is possible to only select the levels in the level selection menu that you already have finished. I've tried it with static variables but now I know that static variables reset if you switch a scene.

This is my Move Around Script:

var speed = 6.0; var JumpSpeed = 8.0; var gravity = 20.0; private var dead = false; private var moveDirection = Vector3.zero; private var grounded : boolean = false; var myClip : AudioClip; static var Level1Enabled = true; static var Level2Enabled = false;

function OnControllerColliderHit(hit: ControllerColliderHit)
// Fall To Dead
{
if(hit.gameObject.tag =="Fallout")
{
dead = true;
HealthControl.LIVES -=1;
}
//End Level
if(hit.gameObject.tag =="End1")
{
Level2Enabled = true;
Application.LoadLevel(3); // selection menu

}
}

Script atached to the gui.text in the selection menu for level 2.

var level2Finished = MoveAround.Level2Enabled; function OnMouseEnter() { if(level2Finished) { renderer.material.color = Color.green; } } function OnMouseExit() { renderer.material.color = Color.white; }

function OnMouseUp()
{
if(level2Finished)
{
Application.LoadLevel(4);
}
}

If you're going to allow players to exit and resume the game, I'd look into the PlayerPrefs class ( http://unity3d.com/support/documentation/ScriptReference/PlayerPrefs.html ). This will allow you to save variables through different playthroughs. So for example, if you finish level 1 do something like :

function onLevelComplete()
{
    PlayerPrefs.SetInt("levelsComplete", 1);
}

So for this example levelsComplete is an int representing the amount of levels complete. Your menu script would check something like this:

if(PlayerPrefs.GetInt("levelsComplete") >= 1) 
//    makeLevelOneClickable

Good answer. Also, if you have a problem with things reseting when changing a scene, use DontDestroyOnLoad.
