Hi,
When I tried to add Scrolling text to star-filed or star-burst the scrolling text flickers...any ideas why?
I tried both vertical and horizontal text scrolls , as well as with a static and with out....
P.S
I have lots of scrolling text examples but I still can't get the "Start trek" effect were the scrolling text goes into space (comes to one point).... If anybody has an example like that ...I would appropriate it... :bg
write the text to the back buffer hmainDC after the stars has been drawn.

I am not so sure that I understand , but I will give it a try...
http://www.masm32.com/board/index.php?topic=16066.0
there are a number of forum threads that cover this
search for "flicker" or "CreateCompatibleDC"
Thanks,
It looks like "Flicker" is a common problem :lol
I came a cross 4 pages on this issue
I also came across this for back buffer:
http://www.madwizard.org/programming/tutorials/mosaic/7
I will give these things a try....

...
I also came across this for back buffer:
exactly this technique is used by the program YOU have shown in your first post in this thread! All you need to change is the order of drawing, so that the text is drawn after the 'stars' has been drawn (to the back buffer
hmainDC).
I understand what you are saying but I think I have 2 Problems that I do not know how to solve:
1. There are 2 "SetTimer" , even though they are written different I still can not get them to separate, the timing for the stars is faster than the scrolling text.... How can I separate the two? what I mean is if I erase one of them the whole thing still works??? If I erase the faster timer for the stars than both the stars and the text run at the slower speed of the scrolling text and vise versa ...
SetTimer for text:
mov TimerID,FUNC(SetTimer,hWnd,IDC_TIMER,SCROLLSPEED,NULL)
SetTimer for Stars:
invoke SetTimer, hWnd, TIMER1, 10, NULL
see : attempts of starfield with dialog rsrc & Scroll Text.zip
2. here is the original text scroll that I used for this, in line 201:
invoke FillRect,hmainDC,ADDR rScroll,rv(GetStockObject,TRANSPARENT) ; OPAQUE VS BLACK_BRUSH VS TRANSPARENT
I took out the black brush so you can see that the text does not copy transparent onto the screen ... how do I fix that....????
in line 171 of starfield2.asm I can fix that by changing "mov hdc,FUNC(GetDC,hWnd)" to " mov chdc,FUNC(GetDC,hWnd)" but than the scrolling text hits the top of the window and scrolls right back down .... :dazzled:
Ahh (http://images.txtagif.com/gifs/0mNFIeMItuU.gif)
there are several methods of solving your problem. However, in the attachment you will find the best solution (IMO) for displaying different animations in one graphic: it creates three memory DCs, where one is used for drawing the text and one for drawing the stars (=this is our background). This two layers are merged in the third DC using Alpha/Transparent blt. This DC is then copyed to the screen. Using this technique allows to quickly combine differently timed animations - However, as you surly can see, it need more system resources (not really hard for nowadays systems/graphic-cards)
Thanks I will take it apart tonight.... it seems to have the same problem too fast of a scroll and stars have the speed of the scroll, but I have not assembled it yet so That might be changeable ....
I was toying with the idea of creating a thread proc for the text like in the horizontal text scroll example that I posted
Any ideas how to fix the Scroll Text Up Example_2a.zip :(...just the scroll example?
- erase hmainDC with some color and not with an hollow brush!
- invoke SetBkMode,hmainDC,TRANSPARENT
- draw the text and Blt it to the screen
- you are the owner of hmainDC: there is no need to endless reselect the font - the same applies for settings like the BkMode/Color

I will give that a try , buy I purposely put Null brush instead of some color(so you can see the error), If you take that example and use "BLACK_BRUSH" every thing looks perfect , but when you add a picture to the background , you get that black (or what ever color was used to erase the background) scrolling on top of the picture (the text is not transparent on top of the picture)
I don't think I understated "- draw the text and Blt it to the screen"
isn't that what is done here:
BitBlt,hdc,0,0,WindowRect.right,WindowRect.bottom,hmainDC,0,0,SRCCOPY
invoke EndPaint,hWnd,addr psI am not clear with what you mean but I will mess with it tonight
for me it works:
invoke SelectObject,hmainDC,rv(GetStockObject,BLACK_BRUSH)
.....
.elseif uMsg == WM_PAINT
invoke BeginPaint,hWnd,addr ps
mov hdc,eax
; erase DC
invoke BitBlt,hmainDC,0,0,WindowRect.right,WindowRect.bottom,hmainDC,0,0,PATCOPY
; draw something for testing purpose
invoke DrawFrameControl,hmainDC,ADDR WindowRect,DFC_BUTTON,DFCS_BUTTONPUSH
invoke SetTextColor,hmainDC,0ffh
invoke SetBkColor,hmainDC,0
invoke SetBkMode,hmainDC,TRANSPARENT
invoke DrawText,hmainDC,ADDR szWindowMsg,-1,ADDR rScroll,DT_CENTER + DT_TOP + DT_NOPREFIX + DT_NOCLIP
invoke BitBlt,hdc,0,0,WindowRect.right,WindowRect.bottom,hmainDC,0,0,SRCCOPY
invoke EndPaint,hWnd,addr ps
Sorry about the late reply, yes you are right it works amazing .....( I did it a little different) :U
I also managed messing with the speeds of the scrolling text that you posted, that worked amazing too....
Thank you for all your help :bg
Hi qWord,
Any Idea how to make my scrolling text example that I posted in this thread "Scroll Text Up Example_2a.zip" do this:
http://www.megaupload.com/?d=5KJFUP0X
just click on the .HTML to view the video :P
....and that assembly you are right about it does crashes... I downloaded it the same day , and on this computer it worked...How ever when I got home on my computer it did not... Strange.... This computer on which it works is an XP as well , however I have no admin privilege here I am a guest... I wonder if that makes a difference?
Appreciate all your help ....
Later on I plan on adding a moon an the star ship Enterprise to it all, so far I can not get the stars to go over the bitmaps, even if I use WM_PAINT to add the images.... :U
It crashed here under Win7
loc_401405: ; CODE XREF: sub_401329+113j

DS:[00000257]=???

I was actually wondering what are the commands to make the scrolling text do that( appear to go off into the distance instead of up)....
In the attachment an quick (and dirty) example using gdi+, which is an adaption from this C# example (http://www.codeproject.com/KB/GDI-plus/StarWarsStyleTextScroller.aspx). The magic function, that does the required matrix transformation, is GdipWarpPath() (http://msdn.microsoft.com/en-us/library/ms534039(v=vs.85).aspx).
qWord
Thanks I will have a look at it.... :bg
Also I found a collection in C++ for demo effects....Here:
http://demo-effects.sourceforge.net/
I would love to know how to do the "Jumping Scroller" and "Sine Scroller Variations" in MASM....
I have a sine scroll example in MASM but I do not like it http://comrade.ownz.com/sources/scroller.zip :(
Using gdi+ path-objects, you can create such effect by placing and transforming characters path's on arbitrary curves. What you need is some basic knowledge on vector and matrix calculations.
Some years back I've played a bit with it, and create an function allowing to place an string on an given path. However, currently I cant share this code and is also a bit buggy - maybe I will step in again and create an lib or dll these days.
In the attachment an application showing this function in action.
i have a question along a related line...
each time WM_PAINT is recieved, i am using the following functions:
SetTextColor
SetBkColor
SetBkMode
SetTextAlign
SelectObject (font)
i am wondering if i need to do them each time, or only of one changes
the problem is that i am lacking a strong understanding of exactly what a device context is
may it be a different handle on different passes ?
once a setting or an object is selected for a device context, does it stay the same ?
the MSDN documents are not very clear on this subject :P
A DC is an structure that holds the current state of an drawing. So a DC have a current (selected) pen,brush,region,font,... and settings/attributes (BkColor,...)
The most importand member is the associated bitmap/display-area. For memory DC's (CreateDC/CompatibleDC) there is a bit map in what ever format - the DCs passed with WM_PAINT are mostly (according to the class style) so called display DCs, which represent a portion of screen. There also printer and information DC's.
AFAIK there is no guarantee, that the DC passed with WM_PAINT is allways the same. Also these DC is used by Windows, so that the configuration changes (selected objects). For memory DC's, which you own, you can select the objects once times.
Maybe also interesting in this context: Driver Development Part 6: Introduction to Display Drivers (http://www.codeproject.com/KB/system/driverdev6asp.aspx)
Hi hfheatherfox07
Just found an example of a sinescroller i did some years ago.
If you want the sources let me know.
Give me a week or so to find my old MASM DirectX7 sources of this sinus scroller.
here some other very simple effect (GDI). It use BitBlt to move pixel-columns vertically from their original position according to current sine value.

I am trying to do examples that use rsrc.rc ....
any ways I was back on the Stanfield today... I got Starfield_rotation to work ... although you still need to define WindowH, and WindowW as numbers.... although if you have it as a secondary window (invoked off a button) ...it works perfect :bg
I keep going back and forth between projects LOL....
I am starting SFX.EXE I would like to create the same thing that Hutch used on his older versions of MASM installation.exe
I figured how to create .cab files using CABARC.EXE and CREATECAB.EXE but I can not create .cab file with actuall folders in it only .exe's and .dll's for some reason
I appreciate all these examples .... I will see how they work with rsrc.rc.....
Still no idea how to create the jumping sine .....
YES !! found it... :bg

Here is a poor attempt to get just the sinescroller... I don't know what to do to initialize the scrolling??? any Ideas???...what don't I need In there???
Also I have a bunch of fonts ... that If I ever get this thing going I would like to use....but I can not find were you set the RGB (255,0,255) as the Transparent color for the font picture, also were did you set the font picture order??? what I mean is not all fonts will have certain Characters in them If you try to use any of the fonts that I have you get misspellings .... where did you set:
fonts db " ? " ' ! # @% $ ABCDEFGHIJKLMNOPQRSTUVWXYZ abcdefghijklmnopqrstuvwxyz 1234567890", 0mine are in a different order ...are they in one of the libs??
Hi hfheatherfox07
The format is just "ASCII" format starting with "space" == (dec)32
In RadAsm you can find an "ASCII Table" on the right side of the toolbar.
Compare it with the picture and you'll understand it.
In the routine "Sinus_scroller" you can find this piece of code:
sub eax,32 ; ASCII value - 32 ( all values below 32 are used to control the speed etc. )
shl eax,5 ; chacracters are 32 pixels ( width and higth ) picture is 256 pixels by 256 pixels ( so, 256/32=8 characters in one row )
mov ecx,eax ; copy character start
and ecx,0ffh ; calculate X pos
and eax,0ff00h ; calculate Y pos
shr eax,3 ; 8 characters in one row to the next row
mov rcScrollFont.left,ecx ; postion in font picture
mov rcScrollFont.top,eax
So, if you want to write a character just substract the value of the character with 32 and you get the right position in de font picture.
This is a fast way of getting the right position in the fontpicture. :bg
But it only works on 256 pixel wide pictures with 32 pixel wide fonts.
( you can change the code to 8*8, 16*16 wide fonts if you want.)
The function "Set_TransparantColor" is in "common\DD_util.asm" and sets that color as the transparent color.
greetings Siekmanski

Sorry no clue how to initiate "Sinus_scroller proc" with out crashing.... it seems that this little demo is very intertwined .... you almost need all the procs that you wrote including size window, why is that needed ??... No luck getting just a black screen with scrolling text :(
Your wish is my command............. :bdg
OK, stripped the source at your wishes.
Now it's your turn to change the font, and it's size.
Quoteyou almost need all the procs that you wrote including size window, why is that needed ??...
It has no need but, the user can stretch the screensize to the size they like. ( you can remove it if you want. )

Thank you so much ....
but I am at a loss about the 2 things still....
1. the ASCII table ( I am well familiar with ASCII to HEX to DEC conversion) but I do not see any were where you added the character order...
how did you declare the character pattern?...most pictures of fonts are not 8 rows by 8 columns
also I realize from your
2.previous post that the transparent color is set in :
The function "Set_TransparantColor" is in "common\DD_util.asm" and sets that color as the transparent color.but I do not see a reference there for (255,0,255) there.... ???
at the risk of looking dumb I just don't see it :(
were in the program would I change the picture-font background to black as transparent for example??
and were would I declare the character order and how.... ????
Thank you and sorry again that I don't see it
You have to rearrange your fontpicture according to the "ASCII TABLE"
ASCII TABLE 32 - 96 ( values used in the font picture )
8 characters per row as in the "ASCII TABLE" starting with space ( value 32 )
! " # $ % & ' ; 32 - 39
( ) * + , - . / ; 40 - 47
0 1 2 3 4 5 6 7 ; 48 - 55
8 9 : ; < = > ? ; 56 - 63
@ A B C D E F G ; 64 - 71
H I J K L M N O ; 72 - 79
P Q R S T U V W ; 80 - 87
X Y Z [ \ ] ^ _ ; 88 - 95
All characters are 32 * 32 pixels ( fontpicture has to be 256 * 256 )
Let's say we want to write "M"
"M" has the value 77
We need to calculate the offset of "M" in the fontpicture to cut it out and copy it in
the scrollscreen.
First substract 32 from 77 because our characters start with "SPACE" which is equal to 32
Let's do the calculations:
77 - 32 = 45
45 * 32 (character width) = 1440 ( keep a copy of 1440 to calc X position )
Y position == 1440 and 0ff00h = 1280 / 8 (characters in a row) = 160
X position == 1440 and 0ffh = 160
Cut out the M at left-top pixelposition 160,160 in the font picture ( 32 * 32 pixels )
all is done in this piece of code:
sub eax,32 ; ASCII value - 32 ( all values below 32 are used to control the speed etc. )
shl eax,5 ; chacracters are 32 pixels ( width and higth ) picture is 256 pixels by 256 pixels ( so, 256/32=8 characters in one row )
mov ecx,eax ; copy character start
and ecx,0ffh ; calculate X pos
and eax,0ff00h ; calculate Y pos
shr eax,3 ; 8 characters in one row to the next row
mov rcScrollFont.left,ecx ; postion in font picture
mov rcScrollFont.top,eax
etc......
; Initialisation of the background color and de tranparent color are done here:
Load_AllPictures proc
invoke Load_Picture,SinusFont,addr g_pSinusFont
mov eax,dwWindow_Width
add eax,32
invoke Create_Surface,eax,32,addr g_pDDSScrollScherm
mov ddBack_bltfx.dwFillColor,RGB(0,0,64) ; set the background color of the scrollscreen and the backbufferscreen ( they use the same struct )
coinvoke g_pDDSScrollScherm,IDirectDrawSurface7,Blt,NULL,NULL,NULL,DDBLT_COLORFILL or DDBLT_WAIT,addr ddBack_bltfx
invoke Set_TransparantColor,g_pDDSScrollScherm,RGB(255,0,255) ; set the transparent fontcolor ( in this case it's pink )
etc......
RenderDD proc hwnd:DWORD
; clear backbuffer with your background color....
coinvoke g_pDDSBack,IDirectDrawSurface7,Blt,NULL,NULL,NULL,DDBLT_COLORFILL or DDBLT_WAIT,addr ddBack_bltfx
invoke Sinus_scroller
etc......
If you want to use other fonts with other offsets you need to make a look up table.....
Thank you Siekmanski ....and I really appreciate the time that you took to explain this to me.... but what I was asking is were do you put the order of the font pictures???
it is not going to look like the ASCII table .... If you look at my previous post on the same page you will see a fonts.zip , the fonts pictures are 10 rows by 6 columns , and others are different again.... you can not calculate that... were is the order ???
http://www.masm32.com/board/index.php?action=dlattach;topic=16710.0;id=9383
As I told you, I don't put the order of the font pictures anyware.
You have to rearrange your fontpicture according to the "ASCII TABLE"
( cut and paste your font order in a paint program to the ASCII order )
Or make a look up table of the offsets in your fontpicture and make your own orders.
PICTURE THIS !!! :bg

Using this technique allows to quickly combine differently timed animations - However, as you surly can see, it need more system resources (not really hard for nowadays systems/graphic-cards)
I have a quick question..... I love your idea with the layers, it is the best ..... does it have to be only 2 layers or can you add more for a bitmap for example?
Here we merge 2 layers .... are more possible or is there a limit?
;/* merge layer 1 & 2 */
;/* copy stars to main-buffer */
invoke BitBlt,hmainDC,ps.rcPaint.left,ps.rcPaint.top,esi,edi,hLayerDC2,ps.rcPaint.left,ps.rcPaint.top,SRCCOPY

Here we merge 2 layers .... are more possible or is there a limit?
the number of layers is limit by available memory. However, each additional layer increase the time, needed for merging the final image. Also, if there are many animations, you should think about a strategy
where and
when to merge the layers. The simplyest would be to merge the corresponding region immediately before copying to the screen, but this increase the CPU usage. An other technique is to merge the final image using an timer e.g. 100 timers per second (this may also required to record all regions that need to be update/merge).
I will give it a try, I want to add image by loading it to a different layer ....
Why don't you do it all with Direct3D or OpenGL ?
You can switch between 2D and 3D in a snap ( or only use it for 2D ), paint everything in a backbuffer at once and then present it all in the frontbuffer.
You can make use of all the tricks then such as Alpha, Depth buffer etc.
And it's as difficult as you make it yourself ......
@ Siekmanski
Now I remember when I was asking you about font structure were I saw it ... It goes like this ....
fTable db ' ABCDEFGHIJKLMNOPQRSTUVWXYZ'

I realized Today while looking through my codes that I had this LOL :dazzled:
Do you think your sine scroller would work like this ( I have not tried yet)? here is a text scroller....
Check this out....
Use Triple Buffering!

Never seen a Triple buffering example used this way....never even seen a triple buffering example
Yes, you can make my routine working with a font table but,
why use a lookup table and a parser if the fonts have the same height and width ?

in the attachment an lib holding the function JmpSine(). A short description can be found in the include file.
(take care of used data types :U)

HI, I just realized , did you make the LibSinText.lib and LibSinText.inc your self?
do you have the asm?

yes

you won't be happy with it, because I used my own macros for the mathematics. (I'm currently working on realeasing them here)
source attached - as said, I'm currently working on a release of the macros, which will come the next days (or weeks).

there are several methods of solving your problem. However, in the attachment you will find the best solution (IMO) for displaying different animations in one graphic: it creates three memory DCs, where one is used for drawing the text and one for drawing the stars (=this is our background). This two layers are merged in the third DC using Alpha/Transparent blt. This DC is then copyed to the screen. Using this technique allows to quickly combine differently timed animations - However, as you surly can see, it need more system resources (not really hard for nowadays systems/graphic-cards)
I like your idea and I have being using it since on different stuff .... here is one that I am stuck with .... inside TEMPORARY.zip
you will find 5 folder ... in the one called TEMPORARY WORK... if you run that you will find that the scrolling text only works if you hold the cursor down on the window frame??? :'(
example 4 the scrolling text works but the rest freezes ???
any ideas???? :(
@ qWord I am beginning to think that the problem is with the dialog -WndProc PROC ... your method seems to work fine with every thing that I tried using just a WndProc PROC dialog ...
This starfiled if you remember I converted from a full screen, and I use a different method a WinMain proc and a WndProc... I was unsuccessful in just using a WndProc and a simple:
INVOKE DialogBoxParam, hInstance, IDD_DLG1 , NULL, ADDR WndProc, 0
INVOKE ExitProcess, 0
Do you think you can give that a try? I think that would solve this problem ... I tried for days and this was the only way to get this starfiled to work with a rsrc.rc ::)
hi,
it is really disappointing to see such code ...
- there was a lot of useless code
- useless/unused global variables
- global variables that could (and should) be local
- handle leaks
- usage of uninitialized variables (hDlg) -> AFAIKS this was the reason why the text doesn't scroll.
- the stars are only visible because you invalidate the window in each iteration of the message loop (!) and because they are drawn while handling WM_PAINT. This is not the idea of using timers and layers: you drawing interval is controlled by a timer (WM_TIMER, timer-ID) and the layers are only combined while handling WM_PAINT.
(I've used a resource ID in the call to CreateDialogParam -> you must change this to get it work)
Thanks qWord ...
I had no idea how to handle the actual star creation.... did not realize that you can put them in a DrawStars proc .....I kept adding them to WM_TIMER
I am going to have to compare the one you made with my bad once to figure out all the mistakes that I made and understand them.....
Thank you again :bg
