I think that will be a must with the mascara! I like the snow splash on landing effect there!

Thanks. It starts to feel kind of funny to play this

 

With this game I screw all my chances of getting any Christmas gifts at all...

[miker]

TBH they barely look like snowballs. ?

Thankfully it's a girl, otherwise it would be even more naughty. ?

Oh geeze. Swedes...

Here is a screenshot with perfectly ROUND snow... Snow GLOBES. Not snowb***s. Soon I change the title to not-nice  

[Igor]

Is everyone remembering this rule from the competition...

• Reference "LynXmas 2020" somewhere in your game e.g. title screen

Yes.

[Nop90]

My title screen.

 

 

Orange color will probably change

[Igor]

Awesome!

 

Hey @karri how do you keep track of and draw the snowballs?  Is it one SCB per snowball or do you use the same SCB and draw it multiple times?

[Igor]

Here's a video of the gameplay, not quite finished of course, but still a few days to go!

I have linked all the sprites and allocated 8 sprites for snowballs. So each snowball has its own hpos/vpos field. Then I have also an extra field named "h" that contains the flight path index.

 

static signed char sparabel[] = {
 1,0,1,1,0,1,1,0,1,1,0,1,0,1,0,1,0,1,0,1,0,1,0,1,0,0,1,0,0,1,0,0,1,0,0,1,0,0,0,0,0,1,0,0,0,1,0,0,0,0,0
};


static int flightpath(sprite_t *Spr) {
    int ret = 3;

    if (Spr->h < sizeof(sparabel)) {
        ret = -sparabel[Spr->h];
    } else {
        if (Spr->h < 2 * sizeof(sparabel)) {
            ret = sparabel[2 * sizeof(sparabel) - Spr->h];
        }
    }
    Spr->h += 1;
    return ret;
}

static void moveshots() {
    sprite_t *Spr = (sprite_t*)&SGirl;
    while (Spr->next != (char *)&SBall8) {
        Spr = (sprite_t*)(Spr->next);
        if ((Spr->sprctl1 & SKIP) == 0) {
            if ((Spr->data == Splash) &&
                (abs(Spr->hpos - SantaX) < 2)) {
                Spr->sprctl1 |= SKIP;
            }
            if (Spr->vpos > 97) {
                Spr->sprctl1 |= SKIP;
            }
            Spr->vpos += flightpath(Spr);
            if ((Spr->sprctl0 & HFLIP) == HFLIP) {
                Spr->hpos += 1;
                if ((SantaY == 98) && (abs(Spr->hpos - SantaX) < 8)
                    && (Spr->vpos > 97-58)) {
                    if (fightmode == 0) {
                        jumptime = clock() + 300;
                        fightmode = 1;
                    }
                    Spr->data = Splash;
                    abcplay (3, "X200I0V20T4R0H10K1O0 g");
                    reducehealth();
                }
                if (Spr->hpos > 168) {
                    Spr->sprctl1 = PACKED | REHV | REUSEPAL | SKIP;
                }
            } else {
                Spr->hpos -= 1;
                if ((SantaY == 98) && (abs(Spr->hpos - SantaX) < 12)
                    && (Spr->vpos > 97-62)) {
                    if (fightmode == 0) {
                        jumptime = clock() + 300;
                        fightmode = 1;
                    }
                    Spr->data = Splash;
                    abcplay (3,
                        "X200I0V20T4R0H10K1O0 g");
                    reducehealth();
                }
                if (Spr->hpos < -8) {
                    Spr->sprctl1 = PACKED | REHV | REUSEPAL | SKIP;
                }
            }
        }
    }
}

So no deep magic. Just a parabel tracking.

I think you mean a parabola

Is it one SCB per snowball or do you use the same SCB and draw it multiple times?

 

You really can't do that, unless you want (!?) to miss the power of linked sprites. It really makes a huge difference. I think Nop in one of his previous game (was it lawnmower?) had huge performance issues, that got fixed once he put everything in a linked list.

Alltså en parabel på svenska.

[LordKraken]

Jag vet

[Igor]

Yep I do use linked SCBs, mostly anyway. In some cases I find it easier to draw some sprites separate because I don't want to bother with sorting based on occlusion/depth i.e. the present can appear in front or behind Santa in my game.

You could simply allocate two present slots. One before and one after Santa. Depending on where you want it you can choose which sprite has the SKIP flag on it. Setting the SKIP flag could be in the final draw process just before the tgi_sprite command. In this way it can depend on the Y-coordinate of Santa compared the where the present is.

I wouldnt do any sorting in a gameplay loop.

 

You could for instance just look at your SCB list as a FIFO. New sprite is put at the beginning and then you just have to shift the other sprites in the list. You pay a bit at the insertion but then you're good. Main limitation is that the z-sorting is done once and for all so if you have different speed, it does not work

 

 

[Nop90]

I don't use linked sprites in Santa Factory because coded it "quick and dirty". If I find the time I'll clean the code ading them before the deadline, but it misses only 3,5 days and it's time to finalize everything.

 

My to do list to complete the game is:

- Make a end game screen

- Complete tune2 now at 25% (ingame tune)

- Add tune3 to the transition screen before starting every level (tune kindly composed by @miker , thank you friend)

- Design the puzzle mode levels (I have only 6 out of 32)

 

Decided to not add bonus tools and the password to resume the game because I'm short of time.

Better to write "covered" but nevetheless you're welcome.

I have to complete the game today because there is no time left before the dead-line. The week-end is already spoken for as well as beginning of next week.

 

The good things: the music and sound effects are ready, the code is ready
The bad things: about 4 hours of graphics work today, no playtesting yet - but it does not matter as I did not write any bugs  

[Igor]

I like the idea of the before and after slots, my current approach is to have the Santa and Squirrel SCBs swap next pointers around depending on which one is 'closer' to the player. Then the present sprite is either drawn before or after the Santa, but not linked into the SCB chain. I do this because the Squirrel doesn't care about where the present is since it either drops it and runs away or runs up to it and steals it.

 

The FIFO idea is good too but I'm not sure it will work very well in a dynamic system that I have where the sprites can move around each other unpredictably.

 

I'm certainly learning new things with this game jam and it feels a lot more like a community project even though we are all working on our own separate games! ?

[LordKraken]

If you have no more than santa and a squirrel, having a regular SCB linked list and just swapping the 2 data pointer is probably the best you can get. If you intend to have more squirels, then maybe not

 

That's ont of the thing I like with 8bits programming, the best engineering solution might actually not be the best in some circunstances

Aren't they going to be one single megapack game in the end

We could name it MegaPak II. Would Songbird approve?

I'd propose: XmasSack

And a red cart.

OMG!!! I was a bit on a rush and then I realized the deadline is not this sunday but next monday, so there is more than 3 days left!!

 

Time to procrastinate then
