Graphics/Tile Functions

Hey!
I am Combou and i am new in this forum.I was searching for a way to create and move sprites, so i found that: http://gbdk.sourceforge.net/doc/html/c0504.html
There is some useful commands there, but i don't know how to use them.I was wondering if someone could help me.
I already know how to create a background and move it.If you don't know, i can try to help you smile

I will make a txt tutorial if I find out how to do it.

Sorry for bad english, i am from Brazil hmm
Thanks! smile

Re: Graphics/Tile Functions

Your looking for move_sprite() and scroll_sprite().

move_sprite(number_of_sprite_to_move, new_x_coordinate, new_y_coordinate) - This will move the specified sprite to (X,Y) on the screen (i.e. an absolute move).

scroll_sprite(number_of_sprite_to_move, move_on_x_axis_this_much, move_on_y_axis_this_much) - This will move the sprite based on it's current location (i.e. a relative move).

Re: Graphics/Tile Functions

Cool!
But you know how to declare a sprite? Like using: set_sprite_tile()

Thanks!

Re: Graphics/Tile Functions

First, load your sprite datas like you would do for tiles data :
    set_sprite_data(UBYTE first_tile, UBYTE number_of_tiles, unsigned char *data);

Then, you have to choose if you want 8*8 or 8*16 sprites. You can do so with :
    SPRITES_8x8 or SPRITES_8x16

And after that, set your sprites from previously loaded datas :
    set_sprite_tile(UBYTE sprite_number, UBYTE tile_number);

    set_sprite_data(1, 1, bgtiles1);

    SHOW_BKG;
    DISPLAY_ON;

    return 0;
}

The sprite is not appearing...What did I miss?

Re: Graphics/Tile Functions

I forgot to mention that you need to use SHOW_SPRITES as for the background and the window x)

Re: Graphics/Tile Functions

If you don't want to display the window, there's no need to use it.
