Video tutorial to create a point & click on Atari Falcon with FGDL

[Orion_]

Hello,

I created a C library for the Atari Falcon that makes it easier to develop games and demos on this machine.
I also created a series of tutorial videos to show an example of creating a very basic point & click with the library.
The FGDL library support 3 different video modes: 320x240x8, 320x240x16, 640x480x8
Double and Triple Buffering.
Virtual screen hardware scrolling.
Palette Fading and conversion from PC format.
GIF Image loading.
Blitter sprite drawing with automatically generated transparency mask.
Keyboard, Mouse and Joystick support.
A Sound mixer with up to 4 channels and WAV file loading.
A Cinepak video player.
CT60 accelerator card and C2P functions.
A random number generator.
A tiny libC for very small executable size.

2 examples are included, one for the standard falcon showing how to create a very basic point & click game, and the second example is a very small demo for the CT60 demonstrating C2P.

Hoping that this can help people to realize their projects on the Falcon

EDIT : My mad, i miss GIF_Load
So it's work now

Noooooo, i failed to display a single gif
I ony got a black screen.

Any idea on what's wrong ?

Code: Select all

#include "tinylibc.h"
#include "fgdl.h"
#include "gif.h"

int _main(void)
{
    char *error;
    uint32_t palette[256];
    uint16_t w, h;
    void *gifdata;

    error = FGDL_Init(VM_320x240_8BITS, 320, 240);

    if (error)
    {
        puts(error);
        return (-1);
    }

    gifdata = ("el1.gif", &w, &h, palette, true);

    if (!gifdata)
    {
        FGDL_Exit();
        return (-1);
    }

    memcpy(FGDL_CurrentScreenPtr, gifdata, w * h);
    FGDL_SetPalette(palette, 0, 256);

    while (FGDL_Keyboard != (FGDL_KEY_ESC | FGDL_KEY_RELEASE_FLAG))
    {
        FGDL_WaitVBL();
    }

    FGDL_free(gifdata);
    FGDL_Exit();

    return (0);
}

Mmm, i try to load my own GIF in VM_640x480_8BITS but i got

Code: Select all

GIF: file 'bg.gif' format error

Strange because it's a 640x480 256 indexed colors.

Yeaaaah.
Thanks to Orion, gif format has to be the old 87a.
I used this online tool https://www.vertopal.com/

I updated the library with a shoot'em up mini game example, I will soon release a video explaining how to do it.

New video tutorial on how to make a Shoot'em Up mini game for the Atari Falcon using the FGDL game library.
In this tutorial we will review the code of the Shoot'em Up mini game example provided with the game library.

Thanks for all your hard work on our platforms. I did enjoy Elansar & Philia a long time ago.
