Unity 3d Using number's as key presses

manilamerc

I need help trying to input number's into the coding here is what I'm trying to do:

If you press the number one it will choose a weapon. If you press the number one again it will choose another weapon. The cycle continues as you keep pressing the number one. If you guys could show me what code could make this happen that would be awesome.

Here is what I got I am so lost

var projectile : GameObject;

function Start ()
{

}

function Update ()
{

if(Input.GetButtonUp("1"))
{
print("axe");
}


}

You'd probably have better luck asking straight coding questions on the Unity forums, or on the Unity Answers site.

var counter:int = 0;
var weaponArr:string[] = ["axe", "knife", "someOtherThing"];
var weaponCount:int;

function Start()
{
  weaponCount = weaponArr.length;
}

function Update()
{
  if(Input.GetButtonDown("1"))  //Down is likely preferable to Up in this case
  {
    counter++;  //increment the global counter
    print(weaponArr[counter % weaponCount]);  // % is modulo, which is handy to "loop" a counter
  }
}

Would a case statement be better for something like this?

For an actual use-case scenario, I'd probably lean towards yes.

Switch(counter % weaponCount)
{
  case 0:
    //stuff
    break;
  case 1:
    //stuff
    break;
  case 2:
    //stuff
    break;
etc
}
