Basics
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.begin();
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)
Bitmaps
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*/ 8,8, /*The bitmap itself*/ B00000000, B00000000, B00000000, B00000000, B00000000, B00000000, B00000000, B00000000
}; (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
