I have a multiplayer 2D game made in Unity and I wanted to put some onscreen buttons to be able to control it on the telephone. The problem is that when I put the Event Trigger on the button it uses the function from the script that has to use and the functions that are called within it, but it can't open [Command] functions at all. Any idea why does this happen?

The Button with the Event Trigger looks like this:

The Event Trigger uses the function TouchInput - function ShootButton (as it can be seen from the picture TouchInput.Button)

The TouchInput function looks like this:

The TouchInput opens the PlayerController script and uses the function "TryFireBullet()". The important functions look like this:

public void TryFireBullet()//(NetworkIdentity id)
 Time.time > ultimul_glont + Delay_Bullet)
 //
 ultimul_glont = Time.time;
 Debug.Log("works2");
 //id.AssignClientAuthority();
 CmdFireBullet();
 //

public void TryFireBullet2() // de_sters

 Debug.Log("LEL");


[Command]
public void CmdFireBullet()

 Debug.Log("works3");
 GameObject bullet = Instantiate(bulletPrefab, gunTip.position, Quaternion.identity) as GameObject;
 NetworkServer.Spawn(bullet);
 //NetworkServer.SpawnWithClientAuthority(bullet, connectionToClient);
 RpcAdaugaViteza(bullet);

[ClientRpc] 
public void RpcAdaugaViteza(GameObject bullet)

 Debug.Log("MERGE_ADAUGA_VITEZA");
 Rigidbody2D rb = bullet.GetComponent<Rigidbody2D>();
 bullet.GetComponent<BulletScript>().creator = gameObject;
 rb.velocity = new Vector2(bulletSpeed * Mathf.Sign(transform.localScale.x), 0f);

Full code of PlayerController script here: https://pastebin.com/R0q7usY7

When I press the Button the Debug shows me:
- "cevaShootButton"
- "works"
- "LEL"
- "works2"

It does not enter in the [Command] function, or the Debug from this function does not print because it is executed on the server? Probably the first one because I can shoot bullets very well without a button using a keyboard key and it also prints "works3" when I do this.

Can you tell me why the button cannot open [Command] functions or how can I replace this type of function?

Thanks.
