+# Background

+
+Renders a full-screen background image.
+
+## Source
+
+
+  
+
+```c
+
+#include <gb/gb.h>
+
+#include "bg_data.c"
+#include "bg_data.map"
+
+void main() {
+
+```
+
+
+
+
+
+
+
+First load the tile patterns in the Background Tile Pattern table. This
+means that we load all the 8x8 images that make up our picture (131 of them
+to be exact).
+
+
+  
+
+```c
+    set_bkg_data(0, 131, tiledata);
+
+    VBK_REG = 1;
+    VBK_REG = 0;
+
+
+```
+
+
+
+
+
+
+
+Then we set the tile pattern in the background tile table. The variable
+`tilemap` contains an array of tile numbers that reference to the the tiles
+we loaded previously using `set_bkg_data`.
+
+Our image is `20` tiles wide and `18` tiles high, thus having a total of 360
+tiles. How is that possible when we only loaded `131` tiles?
+
+Well, that is because some in the image are identical. So instead the tile
+is only saved once in the `tiledata` variable and reused multiple times in
+the `tilemap` variable.
+
+
+  
+
+```c
+    set_bkg_tiles(0, 0, 20, 18, tilemap);
+
+```
+
+
+
+
+
+
+
+In order for the background to actually show up we call `SHOW_BKG`.
+
+
+  
+
+```c
+    SHOW_BKG;
+
+    DISPLAY_ON;
+}
+

+# Big Sprite
+<div style="text-align: center"><img src="screenshot.png" alt="" /></div>
+
+Renders a big sprite of 16x16. Since the Game Boy hardware does not directly
+support sprites that large 
+
+## Source
+Start by including `gb/gb.h` this file defines most important functions you
+are going to need when develop Game Boy games.
+
+
+  
+
+```c
+#include <gb/gb.h>
+
+```
+
+
+
+
+
+
+
+The `sprite.c` file defines the sprite data in the form of an unsigned char
+array. Most of the time you want to generate this file using tools such as
+GBTD.
+
+
+  
+
+```c
+#include "sprite.c"
+
+void main() {
+
+```
+
+
+
+
+
+
+
+Set the sprite size to 8x16 pixels, two tiles one above the other. Internally
+sets bit 2 of the LCDC register to 1.
+
+
+  
+
+```c
+    SPRITES_8x16;
+
+```
+
+
+
+
+
+
+
+Loads the tile patterns stored in `sprite` into the Sprite Tile Pattern
+table.
+
+* first parameter `0` determines at which position we should start loading.
+* second parameter `4` determines how many tiles we want to loading
+* third parameter `sprite` sets the variable to load from
+
+This means that we are loading 4 tiles starting at 0 from the variable
+sprite.
+
+
+  
+
+```c
+    set_sprite_data(0, 4, sprite);
+
+```
+
+
+
+
+
+
+
+Tell sprite `0` to display sprite `0`. Since we are loading 8x16 tiles this
+will make sprite 0 show tile `0` and tile `1`.
+
+
+  
+
+```c
+    set_sprite_tile(0, 0);
+
+```
+
+
+
+
+
+
+
+Finally move a sprite to a position that we can see.
+
+
+  
+
+```c
+    move_sprite(0, 75, 75);
+
+
+```
+
+
+
+
+
+
+
+We want to display a 16x16 sprite. Unfortunately the Game Boy hardware does
+not directly support a sprite that large. So in order to have a sprite of
+that size we are simply displaying two 8x16 tiles next to each other!
+
+Since we've already loaded our entire sprite in line 16 we can now simply
+tell sprite `1` to display our second sprite. Again, since we are displaying
+8x16 tiles this statement will display tile `2` and tile `3`.
+
+
+  
+
+```c
+    set_sprite_tile(1, 2);
+
+```
+
+
+
+
+
+
+
+In order to form the illusion of a bigger sprite we display the second tile
+directly next to the other simply by offsetting the position 8 pixels to the
+right.
+
+
+  
+
+```c
+    move_sprite(1, 75 + 8, 75);
+
+```
+
+
+
+
+
+
+
+As always, in order for the sprites to display we need to call
+`SHOW_SPRITES` once.
+
+
+  
+
+```c
+    SHOW_SPRITES;
+}
+
+
+```

+
+
+A C program always starts by calling the `main()` function. If you are
+unfamiliar with this I suggest reading up on C first.
+
+
+  
+
+```c
+void main() {
+
+```
+
+
+
+
+
+
+
+Prints the string `Hello World!` to the screen. Internally it uses the
+background layer to do so as you can see in the VRAM of your favorite
+emulator.
+
+
+  
+
+```c
+    printf("Hello World!");
+
+```
+
+
+
+
+
+
+
+Using `\n` you can create a new line. In this case it is used to create some
+space between the previous sentence and the next.
+
+
+  
+
+```c
+    printf("\n\nPress Start");
+}
