if get key down unity code example

Example 1: unity key detection

if (Input.GetKeyDown(KeyCode.Space))
        {
            print("space key was pressed");
        }

Example 2: unity get key down

// KeyCode.Space : The key you press
// GetKeyDown : Is true once, when the key is pressed 
// If you want it to be true WHILE the key is pressed, try GetKey() instead
if(Input.GetKeyDown(KeyCode.Space))
{
	// Do something
}

Example 3: if get key down unity

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    void Update()
    {
        if (Input.GetKeyDown("space"))
        {
            print("space key was pressed");
        }
    }
}

Example 4: if(keydown unity)

using UnityEngine;
using System.Collections;

public class classExample : MonoBehaviour{
  
  // variables:
  public float speed;
  public bool grounded
    
  public RigidBody rb;
  
  void Update(){
   
    // on button press / key press here:
    if(Input.GetKeyDown(keycode.W)){
     
      rb.addForce = new vector3(_, _, _); 
      // If you want to add a force then put this line of code on one of the "_"'s:
      // (speed * Time.deltaTime;)
      
    }
    
    // add more movement here if you need:
    // (just remember to change to keycode)
  }
  
  private void onCollisionEnter(Collsion, collision){
   
    grounded = true;
  }
  
  private void onCollisionExit(Collsion, collision){
   
    grounded = false;
  }
    
}

Example 5: unity getkey keycode

Input.GetKey(KeyCode.Space))

Example 6: Debug.Log(Input.GetKey)

void Update()
{
    //get the input
    var input = Input.inputString;

    //ignore null input to avoid unnecessary computation
    if (!string.IsNullOrEmpty(input))
    {
        switch(input)
        {
            case 'a': break;
            case 'b': break;
        }
    }
}
