error CS0029: Cannot implicitly convert type `int' to `bool' - Unity3D

Question

I got error CS0029: Cannot implicitly convert type int to bool error.

Here's my code :

using UnityEngine;
using System.Collections;

public class card2 : MonoBehaviour {

public GUISkin MenuSkin;

public int cardinpuani;
public float sekiz = 8;
public float sifir = 0;
public int onalti = 16;
public int dort = 4;
public int yirmi =20;
public int oniki = 12;
public int yirmidort = 24;
public int yirmisekiz = 28;
public bool clicked = false;

void Start () {

}

void Update () {
}

void OnGUI () {

    GUI.skin = MenuSkin;

    if(GUI.Button ( new Rect (0,Screen.height-50,100,50), "No")){
        Application.LoadLevel(4);
    }
    else if(GUI.Button ( new Rect (Screen.width-100,Screen.height-50,100,50), "Yes")){
    clicked = true;
    }
    else if(clicked=true){
        if(sifir = PlayerPrefs.GetFloat("tahmin", sifir)){
            PlayerPrefs.SetFloat("tahmin", sekiz);
            Application.LoadLevel(4);
        }
    }


    /*if(sifir = PlayerPrefs.GetInt("tahmin")){
        PlayerPrefs.SetInt("tahmin", sekiz);
        if(3>1){
        Application.LoadLevel(4);
        }}

        else if(dort = PlayerPrefs.GetInt("tahmin")){
        PlayerPrefs.SetInt("tahmin", oniki);
        Application.LoadLevel(4);
        }
        else if(onalti = PlayerPrefs.GetInt("tahmin")){
        PlayerPrefs.SetInt("tahmin", yirmidort);
        Application.LoadLevel(4);
        }
        else if(yirmi = PlayerPrefs.GetInt("tahmin")){
            PlayerPrefs.SetInt("tahmin", yirmisekiz);
            Application.LoadLevel(4);
        }*/

        //PlayerPrefs.SetInt("tahmin", sekiz);

        //Application.LoadLevel(4);


}
}

It's simple code but I am still getting error. I tried the commented code too but not succeeded at solving problem. Any help.

You should be using == for comparison in if statement, instead of single = — Habib

You're using the assignment operator

(checked = true)

Which is not the same as

(checked == true)

The first sets the value of checked to true, the second checks if the variable checked is set to true

sifir = PlayerPrefs.GetFloat("tahmin", sifir)

PlayerPrefs.GetFloat returns a float. You can't use a float as the condition in an if statement.

You're looking to do something like

sifir = PlayerPrefs.GetFloat("tahmin", sifir)
if(sifir != 0)
{ 
     PlayerPrefs.SetFloat("tahmin", sekiz);
     Application.LoadLevel(4); 
}

You're also assigning to clicked rather than evaluating clicked in some of your if statements. That'll cause a more subtle bug than failing to compile. Your compilation however, is related to the above.
