little misconfiguration in an exemple #495

Closed PurpleProg closed 1 month ago

PurpleProg commented 3 months ago

in the graphx sprite_moving example this code

   /* Set the palette for the sprites */
    gfx_SetPalette(global_palette, sizeof_global_palette, 0);
    gfx_FillScreen(1);
    gfx_SetTransparentColor(0);

    /* Draw to the offscreen buffer */
    gfx_SetDrawBuffer();

cause the background to be white, regardless of the palette. It should be something like 

   /* Set the palette for the sprites */
    gfx_SetPalette(global_palette, sizeof_global_palette, 0);
    gfx_SetTransparentColor(0);

    /* Draw to the offscreen buffer */
    gfx_SetDrawBuffer();
    gfx_FillScreen(1);

the gfx_FillScreen(1) call should be make after the call to gfx_SetDrawBuffer(). I mean it's not a big deal especially cause here the index 1 is white but just for you know.
