So I have been searching the entire internet for something I'm sure is simple, so here is my question. How would you get text sprites to display on the graph screen like in the game "Donut Quest"? I looked at the code but it is huge and I'm sure I looked over what i needed to notice many times. Thanks ahead of time. Oh yeah, and I guess I should mention I have a TI-84 Plus SE.

Welcome to Cemetech, Sonlen! It's pretty easy; there's basically two types of text sprites. In one, you display repeated text characters, decrementing the y-position of the character each time. In the second, you display repeated text characters, but you increment the x-position each time. That way, you either use the last row of pixels in each character (first method) or the left column of pixels in each character (second method) to build your sprite. Makes sense? Need a concrete example?

These pages helped me with text sprites (and now I've got an rpg that is centered around them ). Welcome to Cemetech btw

Do you generally use spaces to erase the non-last columns/rows of the last character, or do you pick a last character that can be left verbatim?

I've learned how to make them, I just figured there was a lot easier way then typing in 95 characters for a row, like setting up a matrix or a string, and each string represents a function for a certain sprite so that for every number/letter calls for a text sprite.

I personally do spaces, seeing as I haven't found any characters (in other words, I haven't looked) that have a couple spaces at the end. If you want sonlen, I can upload my text sprite helper (store the pixels to a list, and scan through all the letters) though it may only be helpful to me >.>

Edit: That's exactly what I do in my rpg

Actually unless I read that wrong, I have been looking for a program that does that, I have found some out there, but the links to the pages to download are dead.

There definitely is. For example, you could make each of ten sprites be eight characters long, then put them in an 80-character string. Then, define a matrix of values, each value 1-10. To get the substring you'd need for the text sprite, it would just be sub(StrN,1+8([J](A,B)-1), for row A, column B, assuming you're using matrix [J].

One that takes a matrix, and a string, and draws it onto the screen?

@KermMartian I have one question about that code, what exactly is the 1+8 for?

@_player1537 Only one, using both would be a waste of space and make it slow down.

it's easy enough to do that. let's say you want 6*6 size tiles:
start by storing the ascii characters that are required for each tile, one after the other, in a string so that you have all the character combinations you need in a single place(in exemplarum, if you need 12 tiles for your map you would put 12 sets of 6 character tiles one after the other in a single string). next create a matrix or string that defines your tile map using numbers(0-11 since you have 12 tiles). then make a drawing engine that uses the sub command to skip to the character you wish to draw
por ejemplo, if i wish to draw tile number 11 i would do this:
:for(L,0,5
:text([y location of tile in tile map]x6,[x location of tile in tile map]x6+L,sub([str containing your tile data],[number of the tile being drawn]x6+L+1,1
:end
that +1 is there because, unlike any sane programming command, sub starts counting with the first character in the str being number 1 instead of 0

ninja'd =[

@shmibs I almost lost you between all the comments and codes, and I have just 1 question, the x6 would be there since it is 6 characters in the sprite am I correct?

Sonlen, I meant a string as in what KermM is saying, the one with all the characters to use for the sprites, not saying that the string will contain the map data.
The 1+8(matrix data) part is to insure that it always points to at least the first spot in a string, thus avoiding a Dim/Dom error.

Edit: that is correct , though you may want to change that to something else (I prefer 7 imo )

that is the case

@_player1537 Ahhh, I misread what you said then.

Sonlen, I'm going to assume you know how to use matrixes, and strings (like sub() etc). Assuming that, I think it would be a fun challenge for you to write a tilemapper using only basic, and text sprites

I have thought about that, the only issue I seem to be stuck at is storing the text sprites to be recalled. I have been looking for a way for days, and I finally decided to find a forum that I could get help from.

Try this:
"K]]]]]K[[[[[[["->Str1
and to access an element
[A](A,B)
Then to get the part of the string:
Sub(str1,1+7[A](A,B),7

Then just use that string you got from the Sub() statement to write to the screen like any normal text sprite

just hardcode them in your prog and store them to strings whilst running

oh, and you should receive plenty of help with any other problems you may have, so dont hesitate to ask!
