quick question I got this script here to show the name of an Item you collect. These names are made public so I can change them within the item list. What I want to do Is to walk into an item and hover my mouse over the item so it can display the name of the item in the middle of the screen. I don't know if I should use a trigger, or a GUILayout or however. Please Help and thanks. Here is the Script: UPDATED
public class RayCasting : MonoBehaviour

items[randomIndex] = temp;
}
}

Ray ray = new Ray (transform.position, transform.forward);
if (Physics.Raycast (ray, out hit, pickupDistance)) {
foreach (Item item in items) {
if (Input.GetMouseButtonDown (0)) {
if (item.gameObject.Equals (hit.collider.gameObject)) {
numItemsCollected++;
item.Collect ();
break;

Attach following script to every item. It will show QUI.Box when mouse hovers the item. Just change the size of the QUI.Box and set the message to suitable values.
using UnityEngine;

Hello Guys i am working on a small project and I installed the room setup system in the lobby without any problems, and when we set up the room, it directs us to a 2D scene. Everything was exactly what I wanted until now, like the room scene among us. LoadScene("Game"); I added the code and assigned it to the button. When I press the button, the scene changes, but [my status text says connecting but never connected, it's always stuck connecting and therefore players cannot go on stage] I'll share my codes below, can you help me?

For anyone who has a problem like that.
I fixed the problem. I had a .onMoneyChanged in an update function that was making the game crash.
I moved it to the onEnable and onDisable method and now it works just fine.
I'm trying to make a simple condition:
If the value I have, is less than the price it costs the item, the button is disabled.
If the value I have, is greater than or equal to the price it costs the item the button is enabled and I can buy it.
But when I test, I have some problems.
First, if I have less than the item cost the button is enabled, and only when I click on it it is when it disables.
Second, if I have less than the item cost and I click on it it disables, but if I get enough to purchase the item, the button is not enabled again.
How do I to be checked these variables all the time? If I have enough the button is enabled if you do not have it disables.
Bellow my scrip:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class BuySkin : MonoBehaviour {
public int price;
public Button buyBee1;
void OnEnable ()
{
//Register Button Events
buyBee1.onClick.AddListener (() => buySkin (buyBee1));
}
public void buySkin(Button button)
{
if (BeeCoinScore.coin >= price) {
BeeCoinScore.coin -= price;
buyBee1.interactable = false;
}
if (BeeCoinScore.coin < price) {
buyBee1.interactable = false;
}
}
void OnDisable ()
{
//Un-Register Button Events
buyBee1.onClick.RemoveAllListeners ();
}
}
Try this out with some prefabs!

OnEnable()is called when the object becomes enabled and active.
you need Update() as it is getting called every frame it will check whether your value is less than or greater than price of item.You may also try like this.
// I think that you are making an buymenu, so you can disable and enable your menu with ui button and check money you have
using System.Collections;
using UnityEngine.UI;
public class BuySkin : MonoBehaviour
{
public int price;
public static int money;// money you have
public Button thisbuyBee1;
public void buychkr()
{
if(price>= money)
{
thisbuyBee1.interactable = false;
}
else
{
thisbuyBee1.interactable = true;
}
}
void Update()
{
buychkr();
}
}
I'm making a game in Unity3D with C#. I am using GUI.box to show a healthbar for the mobs, but I only want to show the GUI.box if there is a target.
This is my code at the moment.
public GameObject target;
public bool existsTarget;
// Use this for initialization
void Start()
{
PlayerAttack pa = (PlayerAttack)GetComponent("PlayerAttack");
target = pa.target;
existsTarget = false;
}
// Update is called once per frame
void Update()
{
if(target != null)
existsTarget = true;
else
existsTarget = false;
}
void OnGUI()
{
if(existsTarget)
GUI.Box(new Rect(500, 10, healthBarLength, 20), curHealth + "/" + maxHealth);
else {
GUI.Box(new Rect(Screen.width, 10, healthBarLength, 20), curHealth + "/" + maxHealth);
}
Unfortunately this doesn't show any healthbars at all. Any ideas as to why?
Posting the scripts here after popular demand.

public GameObject TheSelectedTarget {get; set;}

} else {

}
deselectTarget();
selectedTarget = targets[index];
}

targets.Clear();
}

Are you ever setting the target anywhere other than the Start() method? The code you show will only ever show a GUI.box if the PlayerAttack.Target is not null at the start. Try moving this code to the Update() method.
PlayerAttack pa = (PlayerAttack)GetComponent("PlayerAttack");
target = pa.target;
Edit:
Check to see if the target is null, that could be the issue.
target = pa.target;
Debug.Log(target);
This will either print to the log as whatever GameObject it is, or null. If it's null, then there is no target.
