Question by MadMAus · Aug 15, 2013 at 01:41 PM · programming

InvalidCastException

This is literally all the code I have:

 var Target = Transform;
 var distanceFromPlayer= 10;
 
 function LateUpdate() {
 transform.position = Target.position.GameObject + Vector3(distanceFromPlayer,0,0);
 }

but I can't get it function properly. I constantly get a 'InvalidCastException' error

Full error: InvalidCastException: Cannot cast from source type to destination type. (wrapper dynamic-method) UnityEngine.Transform.Transform$get_position$ (object,object[]) Boo.Lang.Runtime.RuntimeServices.GetProperty (object,string) UnityScript.Lang.UnityRuntimeServices.GetProperty (object,string) Platformer Camera.LateUpdate () (at Assets/Platformer Camera.js:5)

Help please. :(

Change var Target = Transform; to var Target : Transform;. You have been trying to assign Transform as the class, I figure you want a type reference to transform. This will make it pop-up in the inspector. To assign the transform of the current object do this:

 var Target : Transform;
 function Start () {
     Target = transform; // transform is the component, Transform is the class
 }

Remove GameObject in transform.position = Target.position.GameObject.

still get this error: InvalidCastException: Cannot cast from source type to destination type. (wrapper dynamic-method) UnityEngine.Transform.Transform$get_position$ (object,object[]) Boo.Lang.Runtime.RuntimeServices.GetProperty (object,string) UnityScript.Lang.UnityRuntimeServices.GetProperty (object,string) Platformer Camera.LateUpdate () (at Assets/Platformer Camera.js:5)

I wasn't even meant to have that in there, that was just cuz I got frustrated and started messing about and reading other topics. Not sure what is wrong.

The video that I am using for reference is : http://www.youtube.com/watch?v=1UQqb$$anonymous$$B$$anonymous$$q-$$anonymous$$ and he gets a line where he is able to choose a target, and drop his 'player' into, but $$anonymous$$e is just not there, and I am guessing it is due to this error.

Answer is updated. You were trying to assign the class ins$$anonymous$$d of type referencing.
