Hovering over an Object script and it displays a label

I'm working on a Horror game called Downturn and I've coded a Flashlight script but now I wanna make a script is JS or C# that when I hover over an Object it'll pop up a label in the middle of the screen saying... Press (E) to turn off Alarm. Something along that line and when he/she isn't hovering anymore it'll be removed. ​

 

Also, if it's possible which it is in C# to add something like a toggle for example when hovering over the object it'll show on screen "Press (E) to turn Alarm on" & when the alarm or whatever it is and you hover on the object again it'll say "Press (E) to turn Alarm Off"

without knowing a lot more about your scene/project it'll be hard to provide much more than pointers...

there is the built in:
http://docs.unity3d.com/ScriptReference/MonoBehaviour.OnMouseOver.html
(ignore the reference to GUIElements, that's old UI system...)

or failing that you can look at manually coding something with raycasts
http://docs.unity3d.com/ScriptReference/Input-mousePosition.html
http://docs.unity3d.com/ScriptReference/Physics.Raycast.html
(you wont be instantiating anything but calling a function on the object that was hit to bring up the UI you want for that you'll need a raycast function which has a "out hit" parameter)

basic UI creation is covered in the learn section https://unity3d.com/learn/tutorials/topics/user-interface-ui

 

Thank you I'll look into this.
