In previous versions of the game, I already had tooltips taken care of. However, I upgraded my game project to using the new Unity "uGUI" system (GUI stands for Graphical User Interface). Which is a new GUI system that Unity has transitioned to with the release of 4.6, and now Unity 5 as well.
Unfortunately, Unity 5 (as of this date) does not have tooltip functionality with its new GUI system. For people like me that causes a large sigh and a some rolling of the eyes in disgust. But not all is lost. Fortunately there are some really cool people on the Unity forums. And one of them shared with me some code in order to get a basic tooltip system working. As you should be able to see from the pic I posted, I did get it working finally!
I love tooltips. They allow the player to gain information extremely quick. And guide the player in the use of the GUI (of course). So, there ya go. Tooltips are back in my game now, and I like it a lot. For those of you who may be wondering if the game is still in development, the answer is yes. Cheers for now! I hope to see you guys in game some day :)
