Newbie needs help with the 2D Tut!

[anon_38064576]

Hello guys.

I’m a complete newbie to coding, and I’m already got stuck at a point in the 2D tutorial from the unity website xD

The tutorial tells me to change the hight and/or width of the level boundaries, but I just cant find the piece of code that changes the boundaries.

// Size of the level
var bounds : Rect;
var fallOutBuffer = 5.0;
var colliderThickness = 10.0;

// Sea Green For the Win!
private var sceneViewDisplayColor = Color (0.20, 0.74, 0.27, 0.50);

static private var instance : LevelAttributes;

static function GetInstance() {
if (!instance) {
instance = FindObjectOfType(LevelAttributes);
if (!instance)
Debug.LogError(“There needs to be one active LevelAttributes script on a GameObject in your scene.”);
}
return instance;
}

function OnDisable () {
instance = null;
}

function OnDrawGizmos () {
Gizmos.color = sceneViewDisplayColor;
var lowerLeft = Vector3 (bounds.xMin, bounds.yMax, 0);
var upperLeft = Vector3 (bounds.xMin, bounds.yMin, 0);
var lowerRight = Vector3 (bounds.xMax, bounds.yMax, 0);
var upperRight = Vector3 (bounds.xMax, bounds.yMin, 0);

Gizmos.DrawLine (lowerLeft, upperLeft);
Gizmos.DrawLine (upperLeft, upperRight);
Gizmos.DrawLine (upperRight, lowerRight);
Gizmos.DrawLine (lowerRight, lowerLeft);
}

function Start () {
createdBoundaries = new GameObject (“Created Boundaries”);
createdBoundaries.transform.parent = transform;

leftBoundary = new GameObject (“Left Boundary”);
leftBoundary.transform.parent = createdBoundaries.transform;
boxCollider = leftBoundary.AddComponent (BoxCollider);
boxCollider.size = Vector3 (colliderThickness, bounds.height + colliderThickness * 2.0 + fallOutBuffer, colliderThickness);
boxCollider.center = Vector3 (bounds.xMin - colliderThickness * 0.5, bounds.y + bounds.height * 0.5 - fallOutBuffer * 0.5, 0.0);

rightBoundary = new GameObject (“Right Boundary”);
rightBoundary.transform.parent = createdBoundaries.transform;
boxCollider = rightBoundary.AddComponent (BoxCollider);
boxCollider.size = Vector3 (colliderThickness, bounds.height + colliderThickness * 2.0 + fallOutBuffer, colliderThickness);
boxCollider.center = Vector3 (bounds.xMax + colliderThickness * 0.5, bounds.y + bounds.height * 0.5 - fallOutBuffer * 0.5, 0.0);

topBoundary = new GameObject (“Top Boundary”);
topBoundary.transform.parent = createdBoundaries.transform;
boxCollider = topBoundary.AddComponent (BoxCollider);
boxCollider.size = Vector3 (bounds.width + colliderThickness * 2.0, colliderThickness, colliderThickness);
boxCollider.center = Vector3 (bounds.x + bounds.width * 0.5, bounds.yMax + colliderThickness * 0.5, 0.0);

bottomBoundary = new GameObject (“Bottom Boundary (Including Fallout Buffer)”);
bottomBoundary.transform.parent = createdBoundaries.transform;
boxCollider = bottomBoundary.AddComponent (BoxCollider);
boxCollider.size = Vector3 (bounds.width + colliderThickness * 2.0, colliderThickness, colliderThickness);
boxCollider.center = Vector3 (bounds.x + bounds.width * 0.5, bounds.yMin - colliderThickness * 0.5 - fallOutBuffer, 0.0);
}

Can any of you guys point out the numbers i need to change in that script?

Thanks in advance, and sorry if my english is bad, it’s not my native language, feel free to correct any grammer mistakes if you can!

var upperRight = Vector3 (bounds.xMax, bounds.yMin, 0);

Am I correct that it is this piece of code that draws the size of the level ?

Also, when I open it in MonoDevelop, can I just save and it will automatically be changed in Unity3D ?

[anon_38064576]

Wow. I tried saving it, nothing really happened, exept that I cant see any of the prefabs in the Scene View anymore O.o

If you are changing any file in your asset path (even files in MonoDevelop when saved) unity will update it if it get the focus / active.
You can see that unity is compiling in the lower right corner of unity a little animated icon.

Ah thanks. But I cant continue with the tutorial. Any prefab or asset that I drag into the hierarchy or scene view doesnt show up. I can see it on the hierarchy, but it is not visible in the scene view.

It worked before I changed the values in the script in the OP, and I changed them back, it still doesnt work. I dont know what I did wrong here xD

So please help me? I cant continue without seeing anything in the scene view
