Starting page


When you start creating your game, you should have included these file:

#include <SPI.h> (To communicate with the Gamebuino's screen)

#include <Gamebuino.h> (To get the pre made library)

Gamebuino gb (To create a Gamebuino object named gb)

Then, you'll need to initialize the Gamebuino object in the setup function using this: gb.begin(); and display the menu using the gb.titleScreen function: gb.titleScreen(F("The name of your game"));

For now, your code should look like this:

 #include <SPI.h>
 #include <Gamebuino.h>
 Gamebuino gb;
 void setup () {
   gb.titleScreen(F("My game"));

Customize the title screen

The function gb.titleScreen display only a title, to display a picture, create an 8x8px up to 64*30px PNG/JPG/etc. file and upload it on the Bitmap encoder in the Download, If you want to edit it later, take the binary with multi-line (Wrap output line = true) or if you want it in one simple line choose hexadecimal with a single line (Wrap output line = false)


Do you want to create a bitmap? or maybe create a map of them? It's here

Create a bitmap

Note: If in your game, you enable persistence, you'll need to draw the bitmap each frame.

First, you need to create the bitmap on a byte array like this: const PROGMEM byte Name[] {

 /*The size of the bitmap*/
 /*The bitmap itself*/

}; (You can make it using hexadecimal but it will be harder to modify after.)

0 = a blank pixel/white and 1 = a black pixel

Draw the bitmap

To draw a bitmap, use :

gb.display.drawBitmap(x, y, bitmap, rotation, flip); 

First, there's the coordinate to draw on the screen, x and y. Replace bitmap with the name of the bitmap (It's "Name" in the exemple above). Rotation and flip are optional, replace rotation with NOROT (Not rotation : 0°), ROTCCW (Rotate counterclockwise: -90° or 270°), ROT180 (180 Rotation : 180°) and ROTCW (Rotate clockwise: 90°). For flip, use NOFLIP (No flip), FLIPH (Flip horizontally), FLIPV (Flip vertically) and FLIPHV (Reverse the bitmap, vertically and horizontally).

Draw a map
