I followed this tutorial http://www.scirra.com/tutorials/53/how-to-make-a-port-of-1945-using-construct/page-7 on making a title screen. For those of you who do not want to watch the video I will explain how to make one.
First off create a new layout, we will call it "Title Screen".
When it asks if you wish to create an event sheet along with it select "Add event sheet".
By this point in your game I will assume you have already learned about sprites and all of that jazz so we will not get too detailed on them.
First, add your sprite (If you created one) for the title of your game.
Center it as best as you can wherever you wish. (top, middle, bottom, side, wherever)
Next, double click outside of your game area (the white space around your game) and when the object tab opens, select "Text" under the "General" section.
Depending on what you wish your game to say make the text say something along the lines of "Play" or "Click here to play". Title this text object as "Play". (You can use whatever but the rest of this will make more sense if you use that)
Yet again center this where you want it.
Customize the color, font, size, etc. how you wish.
For now we are only worrying about the "Play" text so don't add any other texts just yet.
Go to your "Event Sheet" (be sure to remember which one applies to this layout) and click "Add event"
(We will assume you want to click with the mouse, if not do the same but with a keyboard function)
Select the "Mouse" icon, and then click "On object clicked".
Choose whether you want it to work on left or right click, and leave "Click type" on "Clicked".
Where it says "Object clicked" select the text icon that says "Play" we created earlier and hit "Ok".
Next to this event we just created for the mouse click "Add action".
Go to the "System" icon and find "Go to layout". Select "Go to layout" and then choose "Layout 1" or whatever your game layout is titled.
Run your layout and your title screen should be the first thing to show up. You should be able to click "Play" (or whatever you put) and it should take you to your game.
If for some reason it takes you to your game first, go back to Construct 2 and drag the tab that says "Title Screen" and put it on the right on the one that says "Layout 1" or whatever your game layout is titled.
If you did everything right you should now have a title screen that you can interact with. Just as you did with the "Play" button. You can add more sprites/text objects to interact with by doing the same thing but using their respective names.
FOR EXAMPLE- Let's say you want to add one of your characters to the title screen so people can click them and go to a page that has his/her/it's biography or something.
You would add the sprite, follow the same steps (creating a new layout, event sheet, and all) and create his biography page.
The sprite would have to be put into your "Title Screen" layout, but when you do the steps for clicking it with your mouse, you change the layout it goes to, to the layout you created his biography in.
If you have any questions on this feel free to comment here and I may (or may not depending on how far in the future you respond) help you.
