I found a similar question asked in Unity Answers and the answer was
“quick answer : - use triggers to check if you’re in front your sign or not - create ui elements for your text - add a script on your trigger with the OnTriggerEnter method, and activates a boolean variable for the next step - in an update on a script in the scene, add a if conditioner to check the input used (Input.GethieyDown or Input.GetButtonDown) - assign your ui elements in your script - activate or desativate your ui elements with the gameObject.SetActive method”
However, I don’t know what this looks like on a script, and the original poster also asked for an example, but their was no follow up, I’d like to ask what this would look like in a script, because I do not know how to code.
First, u need to assign your player with tag “Player”
Then assign this script to your object. (Script name : SignAndPoster)
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SignAndPoster : MonoBehaviour
{
public GameObject signBox; //your UI Box
public Text signText; //your UI TextBox
public string sign; //your UI Text
public bool playerInRange; //checking if player in range
// Update is called once per frame
void Update()
{
if (Input.GetKeyDown(KeyCode.E) & playerInRange) //Show the UI Box and Text when pressing "E" on keyboard
{
if (signBox.activeInHierarchy)
{
signBox.SetActive(false);
}
else
{
signBox.SetActive(true);
signText.text = sign;
}
}
if (Input.GetKeyDown(KeyCode.Space) & playerInRange) //Hide the UI Box and Text when pressing Space on keyboard
{
if (signBox.activeInHierarchy)
{
signBox.SetActive(false);
}
}
}
private void OnTriggerEnter2D(Collider2D other) //Check if player enters the trigger
{
if (other.CompareTag("Player") && !other.isTrigger)
{
playerInRange = true;
}
}
private void OnTriggerExit2D(Collider2D other) //Check if player exits the trigger
{
if (other.CompareTag("Player") && !other.isTrigger)
{
playerInRange = false;
signBox.SetActive(false);
}
}
}
Tell me if you need more help
Notes : You can still walk when viewing the UI Box and text, if u want to disable the player movement, u need another script.
Have the UI object set inactive in your hierarchy (just the parent should be inactive), and have a reference to that parent in your script. Add a collider on the object that you need to be close to. Make it as big as desired, and make sure to set it as a trigger.
bool canPullUpUI;
GameObject uiBox; // your ui box you want to pull up (parent game object reference)
private void OnTriggerEnter(Collider other){
if(other.GetComponent<CustomButtonScript>() != null) // check if we entered the area
canPullUpUI = true;
}
private void OnTriggerExit(Collider other){
if(other.GetComponent<CustomButtonScript>() != null) // check if we left the area
canPullUpUI = false;
}
if(canPullUpUI && Input.GetButtonDown("a")) // make sure we can pull up the UI/pressed button
uiBox.SetActive(true);
This is assuming you have a script on this object named ‘CustomButtonScript’. you could use CompareTag, and compare if collisions gameobject’s name is the same as your ui box. Getting the component is just a quick easy way to check collisions.
