# alert proc

Source: https://ref.dm-lang.org/proc/alert

### Format
> `alert(Usr=usr,Message,Title,Button1="Ok",Button2,Button3)`

### Returns
> Selected button

This sleeps the current proc until the user clicks one of the named buttons. As with input(), the first argument may be entirely left out.

```dm /alert/
mob/verb/self_destruct()
   alert("Prepare to die.")
   del usr
```

A slightly more complicated example provides the user with a choice in the matter:

```dm /alert/
mob/verb/self_destruct()
   switch(alert("Would you like to die?",,"Yes","No","Maybe"))
      if("Yes")
         del usr
      if("No")
         usr << "You have second thoughts."
      if("Maybe")
         usr << "You flip a coin..."
         if(rand(0,1))
            usr << "Heads -- you lose."
            del usr
         else
            usr << "Tails -- you win!"
```
