How can i show the ui button only when pressing on the escape key ?
In the editor i did in the menu: GameObject > UI > Button Now i have in the Hierarchy a Canvas and a Button. What i want to do is when running the game not to show the button and only when pressing on the escape key show the button.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class NodesGenerator : MonoBehaviour {
public Button btnGenerate;
private void Start()
{
Button btn = btnGenerate.GetComponent<Button>();
btn.onClick.AddListener(TaskOnClick);
}
void TaskOnClick()
{
Debug.Log("You have clicked the button!");
}
Just a quick note, btnGenerate is already a Button, creating a new reference btn of type Button to get the Button component results in the same thing. You could just do :
btnGenerate.onClick.AddListener (TaskOnClick);
I hope this helps. wink :)
void Start(){
btnGenerate.gameObject.SetActive(false);
}
void Update(){
if(Input.GetKey(KeyCode.Escape)){
btnGenerate.gameObject.SetActive(true);
}
}
Hey, I assume you want to make a menu type thing, this is one of the simplest ways to do this.
[SerializeField] GameObject button;
private bool isActive = false;
private void Update()
{
if (Input.GetKeyDown(KeyCode.Escape) && isActive)
button.SetActive(true);
else if (Input.GetKeyDown(KeyCode.Escape) && !isActive)
button.SetActive(false);
}
The only thing you have to do after this is dragging the button into the game object slot in the inspector.
This toggles the button on and off when you press the escape key.
