Hi all,

2 examples of programs and videos with the hardware :

Code: [Select]

EXPORT Defender()
BEGIN
 LOCAL xv:=10,yv:=20;
 DIMGROB_P(G1,640, 48);
 DIMGROB_P(G2,320,240);
 Y:=32;
 FOR X:=0 TO 640 DO
  Y:=MIN(MAX(Y-1+IP(RANDOM(3)),0),47);
  LINE_P(G1,X,48,X,48-Y);
  FREEZE;
 END;
 RECT();
 FOR X:=0 TO (640-64) DO
  xv:=xv+2*(ISKEYDOWN(8)-ISKEYDOWN(7));
  yv:=yv+2*(ISKEYDOWN(12)-ISKEYDOWN(2));
  BLIT_P(G2,0,0,320,240,G1,X,0,X+64,48);
  IF GETPIX_P(G2,xv+10,yv+5)==0 THEN BREAK; END;
  RECT_P(G2,xv,yv,xv+10,yv+5,0,#20B2AAh);
  BLIT_P(G0,G2);
 END;
 FOR N:=1 TO 100 DO INVERT_P; END;
END;
I tried the same program with a 40*20 pixels for the spaceship and it run at the same speed

Scroll(1) ->1 pixel scroll

Code: [Select]

EXPORT Scroll(s)

BEGIN
LOCAL x:=100,y:=100;

DIMGROB_P(G1,640,480);  

FOR N:=1 TO 200 DO
RECT_P(G1,IP(RANDOM(640)),IP(RANDOM(480)),IP(RANDOM(640)),IP(RANDOM(480)),0,IP(RANDOM(255^3)));
END;

REPEAT
x:=MAX(MIN(x+ISKEYDOWN(8)-ISKEYDOWN(7),320),0);
y:=MAX(MIN(y+ISKEYDOWN(12)-ISKEYDOWN(2),240),0);
BLIT_P(G0,0,0,G1,x,y,320+x,240+y);
UNTIL ISKEYDOWN(4);

END;

I've no time for now but I did some little tests with the small skeletton of the 'defender'  program (change color, use sprites, kind of 'radar' in the upper of the screen...). I think the integrated langage of the prime is fast enough for fluid programs  like  tretis, 'snake', space invader ... even with scrolling... 

Wow 5 FPS is actually pretty darn good considering that is BASIC. Even the CSE has an hard time pulling this with pure ASM when in 320x240 mode.

SO basically no scrolling unless you want your game to scroll tile by tile, but pretty fast sprite movement and no long map loading

Now to figure out how to avoid having to keep a bunch of tiles displayed to the right side of the screen >.<
