Palm Game Sprite Problem
Hey guys! I am using Code Warrior 7. I am trying make a Palm Pong clone.
I have my sprites running but when ever one moves, the place at which they were, you
can see that still plus where they are now. Understand what I am saying?
I need to figure out how to erase the stop it was just at so that there is only one
picture of the ball at a time. I tried getting a rectangle to erase the last stop but
that doesn't work, or atleast the way I did it.
// The Ball Rectangle
RctSetRectangle (BallRect,Ballx, Bally, Ball-width, Ball-height);
do {
if (hit==0){
if(Ballx148){Ballx++;Bally++;}}
if (hit==1){
if(Ballx148){Ballx--;Bally--;}}
if(Ballx=147){hit=1;}
if(Ballx8){hit=0;}
if(KeyCurrentState()==keyBitHard2){Checkit=true;}
if(KeyCurrentState()0){
if(KeyCurrentState()==keyBitPageUp){delay++;if(delay5){y--;delay=0;}}
if(KeyCurrentState()==keyBitPageDown){delay++;if(delay5){y++;delay=0;}}
if(KeyCurrentState()==NULL){y=y;}}
WinDrawBitmap(Bar1,1,y);
WinDrawBitmap(Bar2,148,yy);
// The Ball
WinDrawBitmap(Ball,Ballx,Bally);
WinCopyRectangle(oldDrawBall,offscreenBall,BallRect,Ballx,Bally,winErase);
Thanks in Advance

C to C++ Conversion problem. PilRC
Ok, I asked earlier how do I use PilRC and Codewarrior 7.0 in C++ mode to use
your own font. The anser I was given was to use
FntSetFont(fntAppFontCustomBase);
Which I used but am still back at step one. How do I use this?
I tried throwing in my old C code
FontPtr Text;
Text=MemHandleLock(DmGetResource('NFNT', 1000));
FntDefineFont (fntAppFontCustomBase, Text);
Which is no good because in C++ mode, it doesn't want to comple this. So how in C++
should I write my code to display User defined font? Thanks in Advance for all your
help!

PiLRC Font C problem
I am trying to use my own Font with my application. I am using Codewarrior R7
with the PilRc plug-in. I set up the compiler and file mappings correctly, and
created a working rcp file.
However, my c code is not compiling correctly, which I don't understand
because all my syntax should be correct acorrding to the Palm Os Documents.
Here is my code,
FontPtr fonte;
fonte=MemHandleLock(DmGetResource('NFNT', 1000));
FntDefineFont(255, fonte);
I get two errors saying
Error : illegal implicit conversion from 'void *' to
'FontType *'
Starter.cpp line 336 fonte=MemHandleLock(DmGetResource('NFNT', 1000));
Error : illegal implicit conversion from 'int' to
'fontID'
Starter.cpp line 337 FntDefineFont(255, fonte);
Something is wrong with my Font pointer but I don't know what. What is wrong?
Thanks!

Screen Saver!
Ok, I am making a simple marquee program for the palm pilot.
Everything works Perfectly except for when I want to exit. The effect I want is when

int num=0;
Int16 penX, penY;
BooleanpenDown;
while(penDown==false){
num=num+1;
if(num10)

scrollx=scrollx-1;

}
}

if(penDown==true)

me? Thanks!

Better algorythm for drawing?
For my drawing program I am saying case penMoveEvent: int x,y; Int16 penX, penY; BooleanpenDown; EvtGetPen( penX, penY, penDown); WinDrawLine(penX,penY,x=penX,y=penY); break; WinDrawLine(penX,penY,x=penX,y=penY); gives you little pixels, how do I make a longer thick line?

I fixed most of my erros on my own but need some help.
I figured out most of the code myself and fix my problems but I thank all
who helped me!
I have one question though.
I am working with a symbol palm and I wrote some code like this
if (eventP-data.ctlEnter.controlID == UpdateScanButton)
{
ScanCmdStartDecode();
bHandled = true;
}
Now my code works BUT
UpdateScanButton is not on the main form so when I try to scan I get an error and have
to reset.
The UpdateScanButton is on the UpdateForm.
How do I say that in this code?
I tried UpdateForm-UpdateScanButton)
But that doesn't work. I tried some other things as well. Thanks!

This is one of my errors I KEEP getting. Please explain it to me and how to solve it.
Warning : function has no prototype
Starter.cpp line 36 {
Error :
illegal implicit conversion from 'void *' to
'FieldType *'
Starter.cpp line 40
FrmGetObjectIndex(FrmGetActiveForm(), UpdateNumberField));
Error : illegal implicit conversion

Error : ';' expected
Starter.cpp line 481
SetField( UpdateNumberField,focusindexed);
What I am trying to do.
I am trying to make it so that when the user scans a barcode it will print the barcode
number of the UpdateNumberField. This is for the Symbol Palm.
I HAVE successfully Inied the palm scanning device and the scanner works. I need help
on the conversion though and displaying the barcode number in the UpdateNumberField.
Please help me! Thanks!

I need some help with some Ui bugs.
Hey! I am trying to make it so that one form will go to another and I got that to work but when I try to make the form return a white screen appears with nothing on it. Also, I tried writing an Exit option that I need to go back to the home screen The screen where you go to when you hit the home key. and I used FrmCloseAllForms(); and that gives me a blank white screen as well.

How do you change a field's text with code?
Hey! I am new to coding for the Palm Os platform. I have code warrior and I am writing
a simple addition program to get use to coding for the palm os platform. I have
figured out the button down event and things like that but am having trouble changing
the text property of a label and a field through code.
I have two fields for the user to type in a number in each. From there I
have it so that when the user clicks the ADD button it performs an adding operation.
My add function looks like this.
static int Add(Int x, Int y)
{
return(x+y);
}
Then in the cltEnterEvent under my Add button code I said
int c;
Add(MainNum1Field,MainNum2Field);
// This is now where the MainAnswerField text needs to display c.
c is the integer and will be the sum of the MainNum1Field and MainNum2Field.
MainAnswerField is where the value a c needs to be displayed.
Can someone PLEASE tell me how to change the text of the
MainAnswerField? Thanks!
GOD Bless!!!
