Sprite is an 8x8 object used in games

A sprite would be stored like
[sprite data]->Pic1
Or pic2, pic3 etc

Inside the [], the sprite is in hexadecimal.
For example,
[FFFFFFFFFFFFFFFF]->Pic1
(16 Fs) would make a block that is all black

To make the hexadecimals, I use the program included in the axe folder that is with the app
 It is called HEXPIC , I believe.

To use them, once you have stored it, like in pic1

Do
Pt-On(X coord, Y coord,Pic1)

(and don't forget to DispGraph ;) )

And if you are making the sprite move, I suggest using
Pt-change(X,Y,pic#)
dispgraph
Pt-change(X,Y,pic#)

pt change simply changes the point from on to off, or vis versa. And pt-on just turns it on, or pt-off which is off. :)

point off just makes the 8 by 8 white, then draws the black part to the screen :P

I usually use an appvar- do this:
Code: [Select]
:GetCalc("appvLELVEL",Y0
:Copy(Y0,L3,768
:Repeat GetKey(15)
:RecallPic
:draw player and stuff
:DispgraphClrdraw
:movement stuff
:End

:GetCalc("appvNameOfAppvar",#OfBytes)->Pointer
then to store stuff into it:
Copy(StuffToCopy,Pointer,#OfBytes)

...such as:
:GetCalc("appvBLAH",768)->A //apvar created and stored into A with 768 bytes (enough for a picture)
:Copy(L6,A,768) //copies buffer into appvar (just like an OS pic)

L6 isn't a "list", such as the lists in the OS, but they are Pointers.
L6 happens to be where the data for the buffer is stored. (buffer: aka: graph screen ;))
when you use the command dispgraph, it evaluates the data in L6 and draws points accordingly.

so could I store a main loop as an appvar? for example, could I have my program set up as this:

in the program it has the menu info, then if you press level 1 it opens appvLEVEL1 which has all of the loop and stuff for that level, ? This is, to store level 1 as an appvar instead of another program.

you can store data in an appvar, but as far as putting code in them, it doesn't work. I'm not sure why, but asm people say that a lot of stuff gets screwed up. (ask asm person for more info)
