Question by Soldier_Jaqqson · Jan 01, 2010 at 02:36 AM · missingcomponentexception

While Going through the FPS Tutorial, I have come across a 'MissingComponentException'

Well While Going through the FPS Tutorial, I have come across a error

'MissingComponentException: There is no 'collider' attatched to the "Launcher" game object, but a script is trying to access it.'

I have simply copied from the tutorial, and I cant come up with any suitable reason why this may be happening, any advice would be much appreciated.

Many Thanks, Soldier_Jaqqson

Personally I think that the forums or the IRC channel are a good place to get ongoing tutorial help, but I'm sure you can get this answered here if you include a few specifics. First, which script is failing? If you click on the error in the Console window you should be able to see the stack trace and jump to the line of the code that generated the error. Also, please tell us what part of the tutorial you were working on. What had you just done or added when the error started occurring?

Well, I would guess you missed one step along the line, to attatch a Collider-Component to your "Launcher" GameObject.
Select your "Launcher" in HirarchyPane and go to Component > Physics > BoxCollider

But honestly I can't remember that the Launcher required that Component.... :-/

No, after reading up in the tutorial, I would assume the problem lies elsewhere:

   Physics.IgnoreCollision( instantiatedProjectile. collider,
       transform.root.collider );
 }
}

I guess your Launcher isn't hirarchicaly attatched to your FPS-Controller-Object.
The Physics.IgnoreCollision accesses the Object wich is the very highest in your hirarchy. That's what the "root" in the transform.root.collider-statement says.
If your Launcher were properly attatched, that would be the FPS-Controller, which indeed has a collider.
Since it's not properly attatched, that is the Launcher, which doesn't (and shouldn't) have a collider.

I hope I could help.

Greetz, Ky.
