Weapon Change Problem Code

How can I switch between the two guns with the space key, but now I can switch from gun 1 to gun 2, and I cannot switch from gun 2 to gun 1.

Code here please help me

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class SilahDegistirme : MonoBehaviour
{
public string[] silahEnv;
public GameObject[] silahListe;
public int suankiSilah;
public bool Silah1, Silah2;
void Start()
{
suankiSilah = 0;
SilahDegistir(silahEnv[suankiSilah]);
Debug.Log("AK47 Secildi");
}


void Update()
{
if (Input.GetKeyDown(KeyCode.Space) && suankiSilah != 0 && silahEnv[0] != string.Empty)
{
SilahDegistir(silahEnv[0]);
suankiSilah = 0;
Debug.Log("AK47 Secildi");

}

if (Input.GetKeyDown(KeyCode.Space) && suankiSilah != 1 && silahEnv[1] != string.Empty)
{
SilahDegistir(silahEnv[1]);
suankiSilah = 1;
Debug.Log("Desert Eagle Secildi");

}


}

public void SilahDegistir(string silahismi)
{
for(int i = 0; i < silahListe.Length; i++)
{
if(silahListe.name == silahismi)
{
silahListe.gameObject.SetActive(true);
}
else
{
silahListe.gameObject.SetActive(false);
}
}
}
}

 

In your Update loop you're processing both 'if' statements one after each other. That means that it'll switch the first weapon and then switch it back again when you press space. For the second 'if' statement you should change it to 'else if' I think.

 

Thank you very much. I asked you how could you understand this?

 

Here's a simpler example:

Code (CSharp):

1. int var = 0;
2.  
3.  
4. if( Input.GetKeyDown(KeyCode.Space) && var==0 )
5. {
6.    var = 1;
7. }
8.  
9. if( Input.GetKeyDown(KeyCode.Space) && var==1 )
10. {
11.    var = 0;
12. }

If you run that and press the spacebar then this happens:

1) First 'if' statement runs and sets var to 1
2) Second 'if' statement runs and sets var back to 0

If you have this instead:

Code (CSharp):

1. int var = 0;
2.  
3.  
4. if( Input.GetKeyDown(KeyCode.Space) && var==0 )
5. {
6.    var = 1;
7. }
8. else if( Input.GetKeyDown(KeyCode.Space) && var==1 )
9. {
10.    var = 0;
11. }

Then this happens:

1) First 'if' statement runs and sets var to 1
2) Second 'if' statement doesn't run because the first 'if' statement ran

If you press space again then:

1) First 'if' statement doesn't run
2) Second 'if' statement runs and sets var to 0

 

Thank you so much for telling
