As KermMartian suggested me yesterday, I propose you my last project named SPRITES Very Happy
( Available here : https://tiplanet.org/forum/archives_voir.php?id=539203 )

I've just translated the file "instructions.txt" (hope my old-school-english 's not too bad!)

First of all, the installation...Just transmit these 6 files :

    backhome.8xp
    clscreen.8xp
    palette.8xp
    print.8xp
    settings.8xp
    sprite.8xp


The SPRITES project v3.2 (for TI83PCE/TI84+CE) is composed of 6 functions, written in ASM, executables from the TI-OS :

1) SETTINGS ,situated in the beginning of your Basic program, initialises the routines, memorises the Status Bar, clears the screen in black, goes to 256-color-mode (8bpp).

If you write the string "+" just before it, that will force to stay in 16bpp mode
(useful for debugging an error in your Basic program!).

inside your program:

Code:
"+":Asm(prgmSETTINGS


or just before launching your program DEMO:

Code:
"+":prgmDEMO



2) CLSCREEN allows you to clear (part of) screen, using one of 256 colors
(see 256_colors.png).


Code:
255:Asm(prgmCLSCREEN

clears the whole screen in white.


Code:
{x,y,width,height,color,x2,y2,width2,height2,color2...:Asm(prgmCLSCREEN

Displays at least one filled rectangle starting at (x,y) position (top left corner).
You'll notice that chaining of parameters is possible.


3) PALETTE
allows you to modify/re-initialise the standard 36-color-palette
(see Palette_36colors.png)


Code:
{255,15,0,...:Asm(prgmPALETTE

changes the first colors of the palette (modifying all the palette is possible)


Code:
0:Asm(prgmPALETTE ou "":Asm(prgmPALETTE ...(well, everything but a list!)
re-initialise the standard palette.


4) SPRITE allows you to define/display a Sprite.

When defining, you'll have to mention respectively:
-its number (0 to ...),
-its width (1 to 35),
-its height (1 to 35),
-its zooming (x1 to x7),
-then pixels data...

As we need to put values higher than 9, we'll use the base 36 (values between 0 and Z ,eg A=10, B=11....Z=35)

For example:


Code:
"000,C3,5
Ans+"0123456789AB
Ans+"CDEFGHIJKLMN
Ans+"OPQRSTUVWXYZ
Asm(prgmSPRITE

define the Sprite number 0 (=000), which size will be 12x3 (=C3), and zoom x5 (=5)

IMPORTANT: : the sprites always have to be defined increasingly : 0,1,2....
Plus, when defining sprite "000", this also (re)set the Sprites Data !

76800 are available for storing sprites (I guess that will be enough)
One sprite = 2+(width*height)*zoom^2 bytes, we can store up to 62 sprites 35x35 , zoom x1 Smile

When displaying, a chaining of several sprites parameters is possible:

For example:


Code:
{0,100,200,1,0,0:Asm(prgmSPRITE

will display the sprite #0, coordinates (100,200) , also the sprite #1 , coordinates (0,0) ( =top left corner of screen) .


5) PRINT allows you to set the displaying mode (graphical position, color/background color (0 to 256), size of characters )
Also allows to display characters (text, variables,...)
Of course, the minus are availables thanks to a double [alpha] key pressing.

For setting...

Code:

{x,y:Asm(prgmPRINT
or

Code:
{x,y,color,background color:Asm(prgmPRINT
or
Code:
{x,y,color,background color,zoom-width,zoom-height:Asm(prgmPRINT


And for displaying...


Code:
"Hello world":Asm(prgmPRINT
x:Asm(prgmPRINT
L1(1:Asm(prgmPRINT
123+4567:Asm(prgmPRINT
π:Asm(prgmPRINT


If you want to "return & go to next line", just put an "i" by pressing [2nd] [.]

Code:
"Hello!iEverything's fine?":Asm(prgmPRINT

will display...

Hello!
Everything's fine?

Let's mention that PRINT will be more accurate :


Code:
π:Asm(prgmPRINT

will display 3.1415926535898 instead of usual 3.141592654

By the way, DO NOT FORGET to use the instruction DEC !
...Or else ,

Code:
 π:Asm(prgmPRINT
will display 1

Be careful to put DEC,FLOAT, MATHPRINT, CLASSIC,...Before Asm(prgmSETTINGS !
Simply because these instructions could modify the Status Bar


6) BACKHOME allows a safe return to the TI-OS :
-clear all Data, converts final screen (and goes back) to 16bpp mode, then finally restore the Status Bar


Code:
Asm(prgmBACKHOME)


If you want not to restore the Status Bar (useful for screenshots!)
just write the string "NSB" (No Status Bar)

Code:
"NSB":Asm(prgmBACKHOME



IMPORTANT, in order not to annoy your dear Calculator:

-SETTINGS must be in the beginning of your program ( 'cause it initialises things...)
-Always define sprites increasingly (from number 0...)
-obviously NEVER try to display an inexistant Sprite!
-I recommend not to display outside the screen
-no more use of display functions: Output,ClrHome,ClrDraw,Text, Line,Pxl-on,Pt-on...

Voilà! I hope that this tool will be useful for your creations.
Have lots of fun ! And good programming !

I give Thanks to Epharius, DjOmnimaga, Diolum (tip "minuscules"), DrDnar (trick "faster/fastest") and others for their advices , testings, tips and inforrmations !!

PS: Please don't hesitate, in case of bugs , tell me, thanks Wink

I must add that despite using Asm(prgmNAME) instead of parser hooks, this lib runs very fast compared to Codex, Zapi, ZSprite, xLIB v0.1a and v0.3a, because of chained commands. What I like the most, though, is that displaying a sprite only requires 3 arguments.
Update : now version 3.3 !
A few optimisations here & there (see the 1st page of this topic for more informations)
Wow, that's actually pretty cool. Did you make that font or was it already part of TI-OS?
The font was from the Amstrad CPC computers from the 80's. I agree that it looks cool Smile (plus you can zoom it in both directions)
Sprites for BASIC (v3.31) now available thru ticalc Smile
