hi i get a problem when i display text on the homescreen.
it displays it correctly the first time then when i restart the game
or go into pause the text isnt displayed where i set it to be which is 0.
heres the code. any help will be appreciated
ty
code:
Main_Menu:
b_call(_ClrLCDFull)
LD HL, 0
ld (PenCol),hl
ld hl,mmstr
b_call(_PutS)
KeyloopMM:
b_call(_GetKey)
cp k1 ;(1)
jr z,show
cp k2 ;(2)
jr z,quit
cp k3 ;(3)
jr z,quit
jr nz,keyloopmm
this is the string
mmstr:
.db " Phoenix Ripoff 1)Play 2)Info 3)Quit",0
like i said before it displays it fine at first then if i restart the game it displays it like half way down the screen
thanks

correct me if I'm wrong, but doesn't _puts look for CURROW and CURCOL for it's coordinate? So loading $0000 into CURROW and calling _puts will put your text at (0,0).
yep

Indeed, do what blueskies said and it should work

Indeed. You storing the location to the wrong place. PenCol is for the graph screen(which is used by VPutS). CurCol is for the Homescreen (which is used by PutS).
change
to
and it should work.

download Ion from ticalc. It comes with the batch file you should use. DevPac8x comes with an updated one for compiling 83+ programs.

I changed your topic title. This will make it more clear to everyone what your question is about, before opening the topic

That should be currow instead of curcol. Ti has never been really consistent. It's
currow
curcol
and
pencol
penrow
If you load HL into currow, L will go in currow and H in curcol.
If you load HL into pencol, L will go in pencol and H penrow.
Loading HL into curcol, will put L in curcol and H in the byte after that, which contains some other system data, you probably don't want to overwrite.

Take a look at
this for the differences between jp and jr.
As for the errors with putsprite, it would be helpful if you were more specific.

I have experienced similar errors when assembling for Ion, though I can't remember exactly what I did to fix them. I can say that it is probably a problem with the conditionals for 83/83+ label definitions.

ok thx and also is there a way to make it were i could make a varible and be able to use it in the tios or a basic program
like i use a asm program to move around and then when it triggers an action it would save the x and y pos of the sprite?
hehe hope i made it clear
thx

You can store values in existing TI-OS variables like Ans, A, B....Z etc. I think it's in asmin28days aswell.

Use this batch file.
Code: Select all
@echo off
echo ==== Now assembling %1.z80 for the TI-83 Plus ====
tasm -80 -i -b %1.z80 %1.bin
if errorlevel 1 goto ERRORS
rem This is necessary because of a DevPac8x bug
devpac8x %1
echo ==== Job finished. Program saved as %1.8xp ====
goto DONE
~Note~ Why would anyone want to compile an 83+ game for Ion?????
Its not as convenient or nearly as reliable as MirageOS.
