Newb at game making Sprite and game map developing

[Sorunome]

As I already said in my previous post, you will need to write your own tilemapping routine

[Duhjoker]

Ok i searcged for tile map routine on the forum and on google and the only hit i got was for the tile map editor.

Can you give me a better clue of what to look for? Please?

[Sorunome]

You could try to come up with your own routine to iterate over the tilemap data and draw the tiles, it should help you to learn more about programming. (for an experienced programmer this is a simple task)

The basic idea is to have two nested for-loops going over the x and y-coordinates and draw the sprites at the correct place.

EDIT: it also helps you to learn about how pointers are working

Here is a simple example showing how a render a tile map : TileMapRAM
For a simple game running a PROGMEM tile map you can look at UFO Race, especially the file world.ino.
Hope that helps!

Just looked at your game example. Actually i was thinking more "descent into hell". Its a room by room type game like Zelda but all dungeon.

I need the room to not move but the chatacter moving around with in, then stepping through a door way to another room and etc.

I just dont know which file to look at to see how the room was built.

ok looking at the arduino example, looking at the first set of code........

Code: Select all

#include <SPI.h>
#include <Gamebuino.h>
Gamebuino gb;

//store the different sprites in PROGMEM to save RAM
const byte grass[] PROGMEM = {16, 16, 0x10,0x0,0x28,0x2,0x10,0x0,0x0,0x0,0x0,0x0,0x10,0x40,0x0,0x0,0x0,0x0,0x0,0x0,0x0,0x80,0x0,0x0,0x40,0x0,0x0,0x0,0x0,0x8,0x4,0x0,0x0,0x0,};
const byte rocks[] PROGMEM = {16, 16, 0x20,0x0,0x50,0x0,0x21,0xe1,0x6,0x18,0x8,0xc,0x8,0x4,0x3c,0x6,0x42,0x7,0x40,0x37,0x40,0x1f,0x23,0x9e,0x1c,0x7e,0x8,0x3c,0x8,0x78,0x7,0xe0,0x0,0x0,};
const byte road_straight[] PROGMEM = {16, 16, 0x1f,0xf8,0x1f,0xf8,0x5e,0x78,0x1e,0x78,0x1e,0x78,0x1e,0x78,0x1e,0x79,0x1e,0x78,0x1f,0xf8,0x1f,0xf8,0x1e,0x78,0x1e,0x78,0x9e,0x78,0x1e,0x78,0x1e,0x78,0x1e,0x78,};
const byte road_turn[] PROGMEM = {16, 16, 0x1f,0xf8,0x1f,0xf8,0x1f,0xfc,0x1f,0xff,0x1f,0xff,0xf,0xff,0xf,0xff,0x7,0xff,0x87,0xff,0x3,0xff,0x1,0xff,0x0,0x7f,0x2,0x1f,0x0,0x0,0x0,0x0,0x40 ,0x0,};

// array containing the different sprites
#define NUM_SPRITES 4
const byte* sprites[NUM_SPRITES] = {
  grass, rocks, road_straight, road_turn};



I see that this is naming the sprites, giving the size of the sprite and then the sprite graphic in hexa-decimal(?)?

do I have to break my sprite into the 0x00 type code or can I just point it to the sprites in my folder?

if I have to use the 0x00 format, how exactly do I render my spites in that format?

[Duhjoker]

Wait...... Do i need to make a sprite sheet first before i start working my tile map?

Still dont understand about the sprites in the example being in 0x00 format though. Cant seem to find anything but i may not be looking up the right term.

[Sorunome]

The 0x00 format is just a format to write numbers, the 0x prefix tells you that the following number is hexadecimal. That is useful as two digets is then one byte and thus you can easily grasp the data without taking up too much space to write.

You will have to convert your sprites with one of your tools to binary/hexadecimal/whatever to include them in your ino to be able to draw them.

Have you already successfully drawn sprites? Perhaps you should start there before doing tilemaps.

[Duhjoker]

I have at least twenty sprites that i made using an online sprite maker but it saves them to .png or you can save at as a base 64?

What tools are out there to turn my sprites to the Hex format. I looked all day yesterday and couldnt find anything.
