Drawing Map from arrays

[STUDIOCRAFTapps]

Hey!
I'm a beginner with all the C's byte stuff because I was creating games for PC and Mac in C# with unity....
Anyway, what I want is to draw maps on screen using ID code, let me explain, here's my map :

Code: Select all

const byte Map[] PROGMEM = {13,9,
8,8,

0,0,0,0,0,0,0,0,0,0,0,0,2,
2,1,2,5,5,8,0,0,0,0,0,0,7,
3,0,0,0,0,8,0,0,0,0,0,0,2,
3,0,0,0,0,0,4,5,2,0,0,0,3,
2,0,2,0,0,0,0,0,0,0,0,0,3,
3,0,3,0,0,0,0,0,0,0,0,0,3,
3,0,3,0,0,0,2,5,5,0,5,5,2,
3,0,3,0,9,0,3,0,9,0,0,0,7,
2,0,2,1,1,1,2,1,1,1,1,1,2,
};

Each id represents a block or an ennemie.
For example, 0 is nothing and 1 is

Code: Select all

const byte PROGMEM Brick[] = //ID: 0
{
  8,8,
  B11111111,
  B00100001,
  B11111111,
  B10001000,
  B11111111,
  B00100001,
  B11111111,
  B00000000,
};

What i want to do: i want to be able to scroll and see the level using arrow. I don't know what to do but i tried this:

Code: Select all

#include <Backlight.h>

How can i make my code work. I don't do it for to awnser but for the knowleght i can get.

By the way: I speak french and my english is vary bad

You might want to check out this thread.........

viewtopic.php?f=8&t=3440

It got everything your asking about and a lil more.

Hello and welcome

You should check out the source code of the SSCCE (Short, Self Contained, Correct Examples) provided with the library
TileMapRAM shows how do draw a tile map stored in RAM.

But RAM is a scarce ressource, so it's better to store your bitmaps and tilemaps in flash memory (aka PROGMEM) if you don't need to change them at run time (as it's read-only memory). So you could look at UFO race, especially the file world.ino, it's a simple game I made with maps stored in PROGMEM.

Thanks it work!

What did you use to help you figure it out, also would love to hear a little bit about your project if you fancy updating us

I just realize that the code half works... I display blocks and the blocks move when i use arrow but the map is only few random blocks placed randomly... For now, i'm experimenty with how gamebuino work, display maps and physic. For testing, before i start my projet, what i want to do is a scrollable map (explore the map using arrows) here's the half working code:

Code: Select all

#include <Backlight.h>
#include <Battery.h>
#include <Buttons.h>
#include <Display.h>
#include <Gamebuino.h>

Gamebuino gb;
byte PlayerPositionX;
byte PlayerPositionY;

byte CurrentMapSizeX;

The real game is... a secret! The name is BIG BLACK BOX, i will start the developpement when i will have engouh knowlegt about gamebuino stuff.

[naed]

I'm not at a computer right now to have a look at your code properly, but will take a look as soon as I can access one.

In the meantime, did you look at the posts Duhjoker and Rodot linked you to, there is so much info on this site around tilemaps... In fact it's possibly the most talked about topic in recent times

[STUDIOCRAFTapps]

So, i've fix the code and it work better than last time! I'm close to what i want. http://pastebin.com/phFbHa7L There's one problem. First two line are wierds... They should be at the end [url]pic.twitter.com/YBsQ8DKW2R[/url] [url]pic.twitter.com/YBsQ8DKW2R[/url]

Any idea? (I can't wait to get my Gamebuino (I'm currenlty using an emulator))

[STUDIOCRAFTapps]

I fix the error myself
