Equipment Screen Display

Question

I'm coding an Equipment screen GUI and so far i'm having problems with square one. my script should display a button on the screen when the "e" key is pressed however it is not doing this.

 using UnityEngine;
 using System.Collections;
 
 public class Equipment : MonoBehaviour
 {    
     public string Kill = "";
     
     void OnGUI()
     {
         Display();
     }
     
     void Display()
     {
         if(Input.GetKeyDown("e"))
         {
             GUI.Button(new Rect(200, 200, 200, 200), Kill);
         }
 
     }
 }

Try using if(Input.GetKey("e")) instead of if(Input.GetKeyDown("e")).

Thank you, it does however need to be held down?

in case you don't want to hold it down, you'll have to add some time interval between the button presses. Do like this (example and explanation here http://docs.unity3d.com/Documentation/ScriptReference/Input.GetButton.html ):

add three variables to your code:

 public float fireRate = 0.5F;
 private float nextFire = 0.0F;
 public bool show;

then, in the update or OnGUI method add this:

 if (Input.GetKey("e") && Time.time > nextFire) {
 nextFire = Time.time + fireRate;
 show = !show;
 if (!show) 
 {
 GUI.Button(new Rect(200, 200, 200, 200), Kill); 
 }
 else
 {
 GUI.Button(new Rect(200, 200, 200, 200), Kill);
 }
