Question about pop up boxes during the game


I would like to ask for help, maybe somebody can explain to me how I can create GUI pop up box (text, images and links), which will appear when player hits the wall and disappear when he will move away.
For example: I have small town with a few buildings and during the navigation when player will come closer to precise building the info box will appear (which will present info about that building: photos, text and etc.) and when he moves away from the building then info box will disappears.
I am kind of new with unity, so I would be glad if somebody can explain me the code which I should use.
Thank you :wink:


one way is you could have two scripts such as the one for the gui which you attach to an empty gameObject. I’m assuming you know how to make a gui box already. Name the object e.g. Info

Then make a empty gameObject at the building and attach a collider and make it a trigger.
Then write something like:

var info : GameObject;

function Start () { = false;

function OnTriggerEnter(theCollider : Collider){
if(other.gameObject.tag == "Player"){ = true;

function OnTriggerExit(theCollider : Collider){
if(other.gameObject.tag == "Player"){ = false

haven’t tested it yet, if there are any problems please ask.

The code he wrote has an error. The if statements should read:

if (theCollider.gameObject.tag == “Player”)

He never defined other so Unity has no idea what to do with it. Try this simple fix and you should be good.
