Why is it showing error?

This is the script, I tried input.getkeydown with switch statements but it is showing error, can anyone tell me the reason behind this? Help Plz!

using UnityEngine;
using System.Collections;

public class SwitchStatements : MonoBehaviour
{

// Use this for initialization
void Start ()
{
switch (gameObject)
{
case (Input.GetKeyDown(KeyCode.R)):
GameObject.GetComponent <Renderer> ().material.color = Color.red;
break;
case (Input.GetKeyDown(KeyCode.G)):
GameObject.GetComponent<Renderer> ().material.color = Color.green;
break;
case (Input.GetKeyDown(KeyCode.B)):
GameObject.GetComponent <Renderer> ().material.color = Color.blue;
break;
default:
Debug.Log ("Invalid");
}
}

// Update is called once per frame
void Update ()
{


}
}

 

Hi,

what kind of error and which line?
but looks like your switch code is bit broken, and its inside Start() function, which runs only once..
need to place it inside Update(), which is the main loop.

tutorial for using switch:
http://unity3d.com/learn/tutorials/modules/beginner/scripting/switch?playlist=17117

 

hello mgear yeah I know tat I have placed it inside start() function but in the update() function too the same thing is happening! the error line is :Assets/Fundamentals/SwitchStatements.cs(10,17): error CS0151: A switch expression of type `UnityEngine.GameObject' cannot be converted to an integral type, bool, char, string, enum or nullable type

 

Have you followed the link? You cannot just put in there whatever you want to. Basically, there are restrictions for types in the switch part and the cases need to be constant values.

 

Hello Suddoha, yeah i now know about it thnx for help!

 

Thnx for help mgear!
