File Name :: Nibbles X
Author :: Harrierfalcon
Category :: Ti-83plus Games
Screenshot :: [img]http://www.unitedti.org/index.php?act=downloads&do=imgss&id=238[/img]
Description ::
The first thing you think is that this is a rip-off of Nibbles II. OK, so maybe the idea is. But the actual coding is still entirely mine. And it's still really fun. All the wipe FX make it seem cooler too.
It might be 1427 bytes, but compared to some other games and all their subprogs, that's pretty small.
Includes a high score, no subprogs, no pics, and several features that prevent both the block and the food. The score is not only based on the amount of food eaten but also the time you survived. Therefore 1 block can be the difference between tying the hi and beating it!
One thing to note is that in Nibbles II, your snake becomes block-immune right after eating for 1 move. this can be used to penetrate and erase blocks, or snake your way into the score portion of the field. Nibbles X fixes this glitch, although it was rather fun.
Credit for ideas goes to Tsuaka X and JP Caron (creator of Snake II). Listed:
Tsuaka X : The 3*3 block for the snake, and the basic playing field.
JP Caron : The "Opening Menu" effect.

Nice! the game runs pretty fast. I'd never have thought that my Snake 2 would inspire someone... Feels great to be credited for code!
After looking in SC2, there are some little code snippets that could be optimized:
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]:Disp " Nibbles X!"," by"," Robert Moy
:Output(1,1,"
changes to
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
:Disp " Nibbles X!"," by
:" Robert Moy
9 bytes saved
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]: D+E→D
:Text(28,22,"SCORE : ",Ans
:If D>∟NIB2(1
:Then
: D→∟NIB2(1
Changes to
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]: D+E→D
:Text(28,22,"SCORE : ",Ans
:If Ans>∟NIB2(1
:Then
:Ans→∟NIB2(1
Saves a little time
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]:SetUpEditor∟NIB2
:Unarchive∟NIB2
SetUpEditor unarchives the list by itself, so no need of unarchiving it after
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
:SetUpEditor∟NIB2
Is sufficient, and saves some bytes
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]:‾62→Ymin
:94→Xmax
:0→Xmin
:0→YMax
could change to:
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]:‾62→Ymin
:0→Xmin
:Ans→Ymax
:1→\triangleX\
which saves 1 byte (hmm)
Also, you might want to use finance variables instead of normal variables. It goes faster (Link to the test), but takes 2 bytes instead of 1

K, quick question. What does storing into [triangle] X do? Obviously it changes window vars somehow, but how does it work?
I'll update it with some optimizations after I'm done.
And yes, Snake 2 was very inspiring.
Thanks for the tips!\
EDIT: 1->[triangle]X set Xmax to 84.

It is actually called delta X and it means change in X. storing 1 to delta X sets the graph screen so that every pixel is one more on the X scale. So, if your Xmin is 0 and delta X is 1, one pixel from the left would have an X coordinate of one, two pixels from the left would have an X coordinate of two. Understand? |

| Ahh...i get it. I had set Xmin to -10, therefore the right-most pixel would be 84. Thanks! |
