Very simple, and addicting. You didn't use my blackening method though... Q.Q

My current version uses a better asm lib so thats not an issue. BTW can I add another screenie somehow?
P.S. Try it you'll soon be addicted, and I bet you can't beat 20.

Send one to DarkerLine.

I think you should get lafferjm to add a sprite function to his API, it might speed things up a bit.

I saw a few [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(12,82)'s in there. You should replace them with [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]12+int(71rand), and replace [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(0,2) with [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]int(3rand), without the parentheses if possible.

I also saw something that looked like this: [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]{LLHS(1),LLHS(2.... You could replace this with [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]seq(LLHS(Z),Z,1,11→L2, which is much smaller. And replace the following one with [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]seq(LLHS(Z),Z,12,22→L3.

These are a few optimizations I see just glancing through, other than the [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]Text(-1, thing.

[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(12,82 and [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]12+int(71rand are of equal size, so we pick the faster of the two.

Perform a speed test:

[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]startTmr→T
For(X,0,E4)
randInt(12,82
End
checkTmr(T

Result: 199

[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]startTmr→T
For(X,0,E4)
12+int(71rand
End
checkTmr(T

Result: 217

Conclusion: [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(12,82 is faster. Replacing [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(0,2 with [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]int(3rand is
still a choice optimization, however, as it saves space without much sacrifice.

Weird. Someone at Cemetech found that the combination of [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]int(0 and [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]rand was faster than [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]randInt(.

Memory-wise, my other optimizations still stand.

ohh ohh theirs an easier way to do that I didn't know any fast way to do this For( loops were too slow.
And about the sprite thing said he was working on it but he said he wasn't skilled enough.

.......

PM him this routine:
Code:
xorSprite:
    ld    e,l
    ld    h,$00
    ld    d,h
    add    hl,de
    add    hl,de
    add    hl,hl
    add    hl,hl             ;Find the Y displacement offset
    ld    e,a
    and    $07             ;Find the bit number
    ld    c,a
    srl    e
    srl    e
    srl    e
    add    hl,de           ;Find the X displacement offset
    ld    de,plotsscreen
    add    hl,de
xorSpriteLoop1:
   ld    d,(ix)           ;loads image byte into D
    ld    e,$00
    ld    a,c
    or    a
    jr    z,xorSpriteSkip1
xorSpriteLoop2:
    srl    d                ;rotate to give out smooth moving
    rr    e
    dec    a
    jr    nz,xorSpriteLoop2
xorSpriteSkip1:
    ld    a,(hl)
    xor    d
    ld    (hl),a
    inc    hl
    ld    a,(hl)
    xor    e
    ld    (hl),a            ;copy to buffer using XOR logic
    ld    de,$0B
    add    hl,de
    inc    ix                 ;Set for next byte of image
    djnz    xorSpriteLoop1
    ret
And tell him it's the code for IonPutSprite.

That might be the code for ionputsprite but i still need to figure out how to read hex data from a string so it can be converted to a sprite to display.

Considering there really is only one sprite in his game, you could hard-code the sprite into your API.

Well It looks like I might just wait and learn asm on my own and make it that way.

I will do that but the next version will hopefully have a sprite function added.

I know you guys will probably be mad because i double posted but oh well. Here is a version of my api TheStorm that has a sprite function in it. The sprite is a man sprite similar to yours but because of the way iputsprite works it had to be 8*8. Just store your x-coordinate to x and your y-coordinate to y. Then just do
Code:
12:Asm(prgmA

Well my original version is now uploaded to Ticalc ( which I submitted 3 mouths ago) and now I have to wait for the screen shots to be uploaded then wait for all the newer versions to be admitted.

P.S. that highscor program is a subroutine I made for the game but then just integrated it in to lightnin, but any one can use it to add high scores with names to their game.

It doesn't necessarily have to be 8*8. The code I gave you has these inputs:

  • a = X location
  • l = Y location
  • ix → Sprite
  • b = height of the sprite in pixels
.
But because this is an API specific to a game, you should be able to set L as a constant, instead of at an input. And because we're only talking one sprite, you should simply be able to have the X coordinate in Ans.

I knew enough about asm to know that but obously he doesn't well I 'll see what I can do. Maybe I should look at other ASM Libs what do you guys think, i was looking at codex if lafferjm needed more experience to finish the api.
