Instantiating Prefab from Javascript - BCE0005: Unknown identifier: 'Prefab'

Archived Forums Questions & Answers

Hello World!

When I try to instantiate a prefab from a script, I receive error message BCE0005: Unknown identifier: 'Sphere1'.

I have made the prefab so I don't understand why I'm getting the error message.

Here's how I made the prefab:

  1. Right clicked inside the "Project View" window->selected create->prefab.

  2. Clicked on GameObject->Create Other->Sphere.

  3. Dragged sphere in "Hierarchy" window onto prefab in "Project View" window.

Here's how I'm instantiating the prefab from the script:

function OnCollisionEnter(collision : Collision) {

var sphere_bullet : GameObject ;
sphere_bullet = Instantiate(Sphere1,transform.position, transform.rotation) ;
}

What I've done so far to try and solve the problem:

Checked "Overview: Instantiate" in Unity manual to see if I missed something:

http://unity3d.com/support/documentation/ScriptReference/index.Instantiate.html

Checked Overview: Script compilation (Advanced) in manual after reading some questions similar to mine:

http://unity3d.com/support/documentation/ScriptReference/index.Script_compilation_28Advanced29.html

Found out that Unity compiles scripts in a certain order leaving in "editor" scripts for last.

Tried changing position of prefab and script in case the script was being compiled before Unity knew anything about the prefab.

Created a new project with a new script and prefab made the same way without any other folders or assets.

Searched Unity Answers for people with the same problem but I couldn't find a solution that worked for me.

Other Information:

The script code isn't contained in any other functions.

The only objects in the "Project View" window are the prefab and the script.

I named the prefab "Sphere1".

Any help would be great.

You need something like:

public var Sphere1:GameObject;

in your script. Then you need to link your prefab to that variable in the script (drag and drop).

You mentioned editor scripts, is yours an editor script? If so, did you look here: http://unity3d.com/support/documentation/ScriptReference/EditorUtility.InstantiatePrefab.html
