| Could someone guide me through the basics of using sprites in a BASIC game? I'm sure this requires an assembly program to do, but I'd like to use it with my future BASIC game. All help is appreciated. |

I know two ways to use sprites in a basic game.
- Using Omnicalc's sprite( function
- Using Pxl-On( s in a separate basic program
They are both roughly equal in space (the first will take up a 767-byte pic, the second approximately 100 to 400 bytes per 8 by 8 sprite). However, the first requires Omnicalc on every calculator running it, though faster.
First way: read Omnicalc manual
Second way: something like
Code:
prgmSPRITES
:If Ans=1:Then
:Pxl-On(R,C+1 (or whatever, sprite pixels go here
...
:End
:If Ans=2:Then
(2nd sprite pixels
:End
so, to do it from your program, do
Code:
:1:prgmSPRITES
for first sprite, the one becomes a number for the # of sprite.
If my explanation seems unclear, ask.

| I've been trying it the second way, but I think I'm going to look into this Omnicalc. |

Yes, sprites.
You have 2 options, hard-code (fast, lots of work and code) them or load them from a variable (slow, less work and smaller).
Hard-coded sprite:
47->A //sprite x position
31->B //sprite y position
Pxl-On(A+1,B+1
Pxl-On(A+2,B+2
Pxl-On(A+3,B+3
Pxl-On(A+4,B+4
Pxl-On(A+5,B+5
From a list:
{1,1,2,2,3,3,4,4,5,5}->L1
47->A //sprite x position
31->B //sprite y position
For(X,1,10,2)
Pxl-On(A+L1(X),B+L1(X+1))
End
Of course you can also use matrices, strings, A-Ø, or any other variable to load sprites from. And you can of course also use lines, circles, pt-on,pt-off, text's, outputs etc. instead of just pt-on. Keep in mind not to make your sprites too big if you need speed, basic is very slow when dealing with graphics (or anything else).

adm.wiggin made me a asm prgm for sprites
each sprite was 16 chars of hex in str1
a=y coord
b=x coord
c=method: (1=and,2=or,3=xor)
works great. only around 100-200 bytes |

| I've tried both the hard-coding and from strings, but the strings seems way to slow and the hard-coding seems fine but a little work. Darth, could you send me this asm program you're talking about? |

| Or better yet, publish it on some TI-site. I'd like that program too and I think most people would. |
