Using Keywords

in Questions And Answers

Hi,
Please could someone help me with the best way to setup using keywords within unity. I am trying to have it so that I can activate and deactivate two planes within my hierarchy by using my hololens with two separate words. Any suggestions would help. Thanks so much!

    It's not a method. It's a property (with a getter and a setter). These look like variables but are just syntactical sugar that make use of implicit method calls under the hood. Learn about them: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/properties

    Look at my code above again carefully. I use an assignment operation, not a method call.

    I simplified things alot and got it to work!
    I used the following

    using System.Collections;
    using System.Collections.Generic;
    using HoloToolkit.Unity;
    using UnityEngine;

    public class HideLayer : MonoBehaviour
    {
    public void showHidePlane()
    {
    if(GetComponent().enabled == true)
    {
    GetComponent().enabled = false;
    }
    else
    {
    GetComponent().enabled = true;
    }
    }
    }

    Thanks for everyone that helped!

    I have implemented Keywords Manager into Unity and it seems to work with changing the color of my plane. Can anyone help me with writing c# script to enable and disable Mesh Render using one keyword?
    Thanks again!

    Should be as simple as calling GetComponent < MeshRenderer > ().enabled = false or true.

    I am still getting an error of unityengine.renderer.enable cannot be used as a method... This is the code that I am using:

    using System.Collections;
    using System.Collections.Generic;
    using HoloToolkit.Unity;
    using UnityEngine;

    public class HideLayer : MonoBehaviour
    {
    public void showhidePlane()
    {
    if (gameObject.GetComponent().enabled != true)
    gameObject.GetComponent().enabled (true);
    else
    gameObject.GetComponent().enabled (false);
    }
    }

    Thanks

    just attach this to your object:

    public void showHide()
    {
        if(objectToHide.activeInHierarchy == true)
        {
            objectToHide.SetActive(false);
        }else
        {
            objectToHide.SetActive(true);
        }
    }

    }
    }

    Thanks

    You also could try GetComponent<Renderer>().setActive = true;

    Thank you, I have done a lot of educational training over the last 12 hours. Unfortunately my coding experience is still beginning. I am now going though a full online c# course. That still does not answer my problem at hand. The get/set examples that I have referenced online are simple in structure. They do not show how to add "if" logic with getter/setter accessor properties.
    It is probably simple to you but now code is saying "Cannot implicitly convert type 'bool' to 'string'
    I know that it is not only a true/false statement but I dont know how else to declare the variables.
    I will keep working on it but direction from anyone would be appreciated.
    Thanks!
    using System.Collections;
    using System.Collections.Generic;
    using HoloToolkit.Unity;
    using UnityEngine;

    public class HideLayer : MonoBehaviour
    {
    public string meshRenderer { get; set;}
    public string Aquifer { get; set;}
    public string ResetAquifer { get; set;}

    private string aquifer()
{
    meshRenderer = GetComponent<MeshRenderer> ().enabled = true;
    meshRenderer = GetComponent<MeshRenderer> ().enabled = false;
}
private string resetAquifer()
{
    meshRenderer = GetComponent<MeshRenderer> ().enabled = true;
    meshRenderer = GetComponent<MeshRenderer> ().enabled = false;
}

    }
