I placed a sprite and artifacts appeared

BMP_init(TRUE, BG_B, PAL1, TRUE);
BMP_setBufferCopy(TRUE);
SYS_enableInts();
u16 ind = BMP_FB1ENDTILEINDEX ; //TILE_USERINDEX;
VDP_setPalette(PAL0, cabin.palette->data);
VDP_drawImageEx(BG_A, &cabin, TILE_ATTR_FULL(PAL0, TRUE, FALSE, FALSE, ind),0, 0 ...

Also I want to place sprite behind two layers.

1.) how to set offset address of sprite after:

Code: Select all

 u16 ind = BMP_FB1ENDTILEINDEX    ;
 ind += cabin.tileset->numTile;

2.) how to set attributes priority?

alko

Code: Select all

 line = MEM_alloc( sizeof(Line));

alko

Now Line is not drawn

Code: Select all

 Line *line;
line->pt1.x =0;
line->pt1.y =0;

line->pt2.x =100;
line->pt2.y =100;

line->col=10;

BMP_drawLine(line);

alko

I set:
IMAGE cabin "cabin.png" FAST
artifact is gone

alko

when I change in gfx.res

Code: Select all

IMAGE cabin "cabin.png" -1

to

Code: Select all

IMAGE cabin "cabin.png" 0

The artifact has changed position

maybe rescomp doesn't work properly?

on Blastem visible similar artifact too

I use BMP_flip(1) double-buffered render and I can't understand why this artifact appeared in Kega Fussion

I want put image over bitmap_render layer

VDP_setPalette(PAL1, palette);
VDP_setScreenWidth320();

VDP_clearPlane(BG_A, TRUE);
VDP_clearPlane(BG_B, TRUE);
BMP_init(TRUE, BG_A, PAL1, FALSE);
BMP_setBufferCopy(TRUE);

//JOY_setEventHandler(joyEvent);
SYS_enableInts();

u16 ind = TILE ...

i'm trying to draw a quad

Vect2D_s16 * pts;

u16 palette[16];

int main()
{
MEM_free(pts);
palette[0] = RGB24_TO_VDPCOLOR(0x000000);
palette[1] = RGB24_TO_VDPCOLOR(0x0000FF);
palette[2] = RGB24_TO_VDPCOLOR(0x00FF00);
palette[3] = RGB24_TO_VDPCOLOR(0xFF0000);
palette[4] = RGB24_TO_VDPCOLOR ...

alko

why are repeating and symmetric tiles from sprites stored in VRAM as unique ?

alko

Thanks. Now it works correctly.
