OnTriggerEnter Get Key

Hey guys, i’m new to the Unity3D and i’m trying to do something. If player is in the Trigger he/she needs to press a button in keyboard in order to get in the house. I tried everything but i couldn’t make it work. I’m making a 2D game with sprites.

Sorry for my bad English. Thanks!

try using this code
you need to have a tag “house” attached to the house

    using UnityEngine;
    using System.Collections;

public class enteringthehouse : MonoBehaviour {
	
	bool enter; // boolean to determine whether you are inside the trigger or outside
		
	void Start () {
		enter = false; // before entering the trigger area
	}
	
	// Update is called once per frame
	void Update () {
		if (enter == true&& Input.GetKeyDown(KeyCode.Space)) // determine that only after the trigger is
		{													// true and you press space you can enter the house
			Debug.Log ("you can enter the house");//open the door ?/ change to other scene ? up to you
												 // just put the code here
		} 
	}
	
	void OnTriggerEnter (Collider collider)
	{
		if (collider.gameObject.CompareTag ("house")) //entering the trigger/collider attached to the
													// house. the house object must have tag named "house" 
		{											// with both of these enter will only be true when you are 
			enter = true; 							// inside the trigger
		} 
	}
	
	void OnTriggerExit (Collider collider)
	{
		if (collider.gameObject.CompareTag ("house")) //exiting the trigger/collider attached to the 
		{												// house cause enter to become false
			enter = false;										
		} 
	}
}
