Displaying one character at a time on the graph screen

I can't get the spacing right on this thing. D:>

Code: [Select]
"experience points!->Str27
...
For(X,0,17
Text(X*4+3,3,{Str27+X}
End

You need to end that with >Char (>Frac with TI-tokens) to display it as a single character instead of the whole string every time.  Small fonts are variable sized letters, so it is not possible to assume that each letter is exactly 4 pixels wide as you are doing.  It is possible to do this in the next update though becasue I will allow you to display text without defining coordinates first kind of how you can use Disp instead of Output() and then you don't need to keep track of the location at all.

However, I feel like I can still help.  You can use this (http://ourl.ca/4129/91820) to get the width of a string on the graph screen.  That way, you can figure out the width beforehand.  I'm not too sure how you would make this work with what you are trying to do, though.

That was because the post count has been deducted when DJ removed all Axe topics...
Luckily he restored it all :)

Hmm.

Would this work for finding the width of each character?

Code: [Select]
"experience points!->Str27
<delta>List(33,105,102,108,116,122->GBD1
...
For(X,0,17
sub(WD,Str27+X)
Text(1+Y,1,{Str27+X}>Frac
Pause 100
End

Lbl WD
If r1={GBD1} or r1={GBD1+1}
1->Y
End
If r1={GBD1+2} or r1={GBD1+3} or r1={GBD1+4}
2->Y
End
If r1={GBD1+5}
4->Y
End
Return

You shouldn't need the >Dec when calling the sub, I'm pretty sure that's just for displaying.


Spoiler For Projects:

My projects haven't been worked on in a while, so they're all on hiatus for the time being. I do hope to eventually return to them in some form or another...

My big personal project, an original RPG about dimensional travel and a few heroes tasked with saving the world.
Coding-wise, on hold, but I am re-working the story.

I will be combining Blur and Collision Course into a single gamepack. On hold.

Spoiler For Nostalgia Origins: Sky's Story:
Prequel to Nostalgia. On hold, especially while the story is re-worked.

In the string that you have, each character is 4 pixels wide (including the gap between characters) except for the space and the exclamation mark.  The space is one pixel wide, I'm not sure about the exclamation point.
You need to be careful about the space, "w", "z", and "*".  There might be more, but those four characters are the common ones I use that have different widths.

I wonder if we could modify the routine I posted to use the extra screen rows under the visible LCD memory?

Right.
There are 8 rows of pixels below the screen and 8 columns of pixels to the right of the screen in the LCDs internal memory, if I remember correctly.

What? IIRC, there are no extra rows, but the screen is 120 bits wide (in LCD RAM)
