Questions & Answers

i wanna do something like this in c# on unity engine:

int main()
{
char ch;
ch=cin.get();

if(ch==‘a’){
.
.
.
}

cin.ignore();
cin.ignore();
return 0;
}

i don’t want player see which key he pressed down on the screen. (so i don’t want use Input Field)

thank you in advance

The closest equivalent would be Input.anyKey and Input.inputString. Since Unity is a real time engine you poll these each frame and check against your desired outcome, hence ‘a’.

first of all thanks to @hexagonius for the answer.

i found 2 ways of saving player’s input to a variable without Input Field that i wanna share them with you:

  1. using Input.inputString (as @hexagonius mentioned):

example:

void Update () 
{

       foreach (char c in Input.inputString)
        {
            if (c == 'a') { ... }

        }
     
  }

in my experience of using Input.inputString i realized that variable should be initialized within foreach parentheses. Therefore variable is only defined within foreach brackets.

Input.inputString on unity docs

  1. using Event:

Example:

private void OnGUI()
    {

        Event e = Event.current;

        if (e.character == 'a') { ... }

    }

Event on unity docs

in my experience of using this tow methods, using first method is better for resources.
