Mouse over and press E script - help please!

Unity Engine
1

So i’m trying to make a script that makes a Gui label appear when I have the mouse over an object and press E to “interact” with it. So far i’ve got the gui label to appear with just mouse over, but I only want it to appear with mouse over AND when I press E. I’ve tried placing if (Input.GetKeyDown (KeyCode.E)) but to no avail. What would be the next step into making this script work? Thanks.

var mouseOver : boolean = false;

function OnMouseEnter() { mouseOver = true; }
function OnMouseExit() { mouseOver = false; }

function OnGUI() {
    if (mouseOver) {
        GUI.Label (Rect (10, 10, 100, 20), "Hello World!");
    }
    }
2 
if(mouseOver  Input.GetKeyDown (KeyCode.E))
{
    GUI.Label (Rect (10, 10, 100, 20), "Hello World!");
}

It doesn’t seem to do anything at all now (except the “mouse over” check box gets ticked whenever I do mouse over the object, so that is working, but I had that working anyway) . This is my script currently adding what you just gave me (I think I did it right, i’m still relativly new to this.) Is the following correct?

var mouseOver : boolean = false;

function OnMouseEnter() { mouseOver = true; }
function OnMouseExit() { mouseOver = false; }

function OnGUI() {
    if(mouseOver  Input.GetKeyDown (KeyCode.E))
     {
        GUI.Label (Rect (10, 10, 100, 20), "Hello World!");
     }
     }

Sry, i didn’t thought too much before posting. The reason why the above code is not working is the fact that Input.GetKeyDown() is a one time event and is triggered only once, while the code in OnGUI() is executed each frame. This should work:

        if (showBubble  Input.GetKey(KeyCode.E))
        {
            GUI.Label(new Rect(20, 50, 150, 40), buildingType.ToString());
        }

Thanks you’re first post helped a little in conjunction with another friend who hepled me out. It’s working as I need it to now :slight_smile:
