Triggering animation in NPC when Player presses Left/right Arrow keys or A or D key.

Hi, I'm trying to make it so that when the player is within a certain of a non player character, and the player is pressing the LeftArrowKey, the RightArrowKey or A or D (in the WASD), an animation plays on the NPC.
I understood that "Horizontal" covered these buttons like Fire1 covers the LeftMouseButton.

If anyone would please point me to a solution that would be great.

Code (CSharp):

1. // Update is called once per frame
2.     void Update () {
3.  
4.         bool down = Input.GetButtonDown("Horizontal");
5.         bool held = Input.GetButton("Horizontal");
6.         bool up = Input.GetButtonUp("Horizonal");
7.        
8.         if (Vector3.Distance(Player.transform.position, NPC.transform.position) < Distance && Input.GetButtonDown("Horizontal")) {
9.             NPC.GetComponent<Animation>().Play("Animation_One");
10.         }
11.     }
12.  
13.  

 

"Horizontal" is the name of an axis, not the buttons; it works with GetAxis.

Code (csharp):

1. if (Vector3.Distance(etc) < Distance && Input.GetAxis("Horizontal") != 0f)

Be advised that this is one of very rare instances where it's okay to check for exact equality (== and != ) with floats, because 0 is the exact value that's returned when the axis isn't being pressed. Analog input or joysticks might make that dicey, though, if you allow non-keyboard input, so you'd want to check for a range instead if so.

 

Thanks for your feedback.
