- For letting the player interact with the game with their mouse, see Touch screen.
This page describes the concept of dual screens. Essentials does not have a dual screen, although the Nintendo DS and Nintendo 3DS do.
A dual screen is a method of dividing the game screen into two or more segments. Most commonly people will do this in the same way the Nintendo DS does, namely having two equally-sized screens, one above the other with a small dividing area between them - however, this is not the only possible layout.
Note that a dual screen is different to a touch screen. A touch screen simply allows the player to use the mouse in-game. The Nintendo DS has both of these features, but they are by no means dependent on each other - you can easily have one without the other.
Essentials does not include or feature a dual screen in any configuration.
- You don't need to mimic the Nintendo DS screen layout. Your screens can just as easily be different sizes to each other, and/or in different places.
- One possible layout is to have a narrow second screen along the bottom. This can display the player's party when idle, and message boxes when they are required.
- Think twice before emulating the HeartGold and SoulSilver second screen menu. Having the menu always visible (particularly with the "Save" and "Options" buttons) can detract from the player's immersion in the game. Instead, why not put something game-relevant there instead, like the Pokétch or buttons for key items, or even a description of the current map?
- If you're also making your game mouse-compatible, remember that you don't need to have all the touch screen buttons in just one of the screens (e.g. the lower one) like the Nintendo DS does. You can make the entire game screen touch-sensitive - this makes sense when you consider that you're making a PC game which doesn't have the restrictions that the Nintendo DS has.
- You don't need to keep the two screens separate all the time. Consider the advantages of using one big screen in some cases.
