set value to a component

Question

I am trying to control and set some values to a UnitySteer Radar component. UnitySteer

I am trying to set it up like that:

     gObjParent.GetComponent("Radar").LayersChecked = 1;

but it gives me: Type UnityEngine.Component' does not contain a definition for LayersChecked' and no extension method LayersChecked' of type UnityEngine.Component' could be found (are you missing a using directive or an assembly reference?)

Here is the code for the radar script, or at least what I think is applicable.

     [SerializeField]
     LayerMask _layersChecked;

. . .

    public LayerMask LayersChecked {
     get {
         return this._layersChecked;
     }
     set {
         _layersChecked = value;
     }
 }

Use the generic version of GetComponent:

 gObjParent.GetComponent<Radar>().LayersChecked = 1;

When you use a string paramter for a GetComponnet() call, the compiler does not know the type of the component and defaults to the Component class. Note I'm assuming C#. For Javascript:

     gObjParent.GetComponent(Radar).LayersChecked = 1;

Thank you for the answer. now I'm getting: Assets/scripts/constructor.cs(77,41): error CS0246: The type or namespace name `Radar' could not be found. Are you missing a using directive or an assembly reference? Do you have a solution for that? What I'm using is:

 gObjParent.GetComponent<Radar>().LayersChecked = 1;

and yes C#

Is the Radar class included in your project? If so is it C# or Javascript? If it is Javascript, you will have to take a look at moving the script to another location so that it is compiled in a earlier pass:

Considering the link to the GitHub project, the radar class is C# but is included in a namespace, so you need to add it to your project:

  using UnitySteer.Base;

Yes it is included. I can actually add Radar component either from the components->UnitySteer->Radar->Radar.

 gObjParent.AddComponent("Radar"); - this works as well
