Just ported this to the TI-83! Took me an hour to transplant code XD

The TI-83 non-plus? What did you do that for?

Yes, I highly recommend you list out variables, A-/theta/

I like to keep things simple though, so I use the same variables over and over for a lot of things.

K- getKey
W- While loops
F- For( loops
/theta/ or Z- variable used when going to a sub-program to tell the subprogram what you want done
A- Cursor location

And I have a list of temporary variables that does not store any important data at all, the data itself is expected to be obliterated after something else is run.

As to your code, you could have a simple 2 element list defining sprite size. Using the spaces will just eliminate the map segments that it takes over. You would need to then have a list of If:Output( to a certain extent to show which parts you want. Like how I did with the map in pokemon, sort of.

Say we have one Output that is the 'middle' of the sprite when a sprite height is odd, or the 'top-ish' if the height is even. It is in A

5->A

The sprite looks like this:
O
|
^

This is stored in Str1

We would have a list, L1 for the moment, that is {1,3-L1

Then the list of outputs. For the time being, let's limit the total height to 5.

If L1(2)=5:Output(A-2,X,sub(Str1,1,L1(1)
If L1(2)>=3:Output(A-1,X,sub(Str1,1+2(L1(1)(L1(2)>3))-(L1(1)(L1(2)>3)),L1(1
If L1(2)>=1:Output(A,X,sub(Str1,1+3(L1(1)(L1(2)>1))-(L1(1)(L1(2)>1)),L1(1
If L1(2)>=2:Output(A+1,X,sub(Str1,1+4(L1(1)(L1(2)>2))-(L1(1)(L1(2)>2)),L1(1
If L1(2)>=4:Output(A+2,X,sub(Str1,1+5(L1(1)(L1(2)>4))-(L1(1)(L1(2)>4)),L1(1

(Please note, this code is not tested, just what I was able to come up with off top of my head. It works on paper, just not tested on calc. I am sure it could be optimized into something a bit better, but for the sake of explaining how it could be done in it's simplest form, this should work.)

This of course needs to be in a loop and getKey implementation and all that.

I might get curious enough later to test out this theory. Of course you will need some more stringent limits inside the getKey code for displaying near the borders and such.

Any of the other BASIC coders have any thoughts?

Edit:

I just tried out the code above, it does not work for anything less than 5 rows at this point. Not really sure why, but it seems to handle the columns dynamically.

A very thorough and totally understandable post for qazz, tifreak8x! I have nothing to add to that.

tifreak, sadly, I have not used the sub command ever, I plan to learn more TI-BASIC once the contest is over....

sub( is easy enough to understand, though can get confusing sometimes.

sub(Str,start point,include how many characters

example:

sub("OH HI, I'M A DRAGON",4,6

Would post

"HI, I'"

The 6 tells the parser, how many characters to the right it should go. And it includes the starting point.

That help?

o_O yes, I have been wondering a while what sub() did, thanks tifreak

Do you know about the related command inString() ?

No... ;.;


No need to tell me though, I have tibasicdev

For everyone else, it's for finding if and where a string is in a same-sized or larger string. You can look for letters in a long string (for example, to convert letters to numbers without a massive string of If... statements), or you can search for substrings.

yeah, Ik now it is useful for maps


anywho, released it on ticalc

It is called "sprite demo"

posting link later

Much later, in fact, since ticalc.org seems to be pondering the archives submissions ever since I submitted NetPong.
