Generic Questions

mmmmm .... I think the real problem is in the format of the sprite.
I use a sprite png 24-Bit and then memorize over 2000 colors.

I want to change the colors of 200 sprites.
and do this with photoshop is a big job!

I have not found a program that does this job automatically in many sprites.

The code I wrote seems to work, but for a single sprite are requests more than 2 hours of work. 

Another question:
I tried to use the command setshoebox, I work well with sprites and music, but I do not read txt and ini is this normal?

[kanonet]

Two hours for a 200x200 sprite? Are programming on a pocket calculator? lol
There must be something going on really bad or how much do you do inside the loop? It should never take that long. Be sure that you dont have debugmode enabled.
If you want you can post your code here or pm it to me, i will have a look at it. Maybe you should also include one sprite too.

You need to set up a good ACTION in photoshop and batch things.

Programming such on GLB is more versatile though.

thanks for help.

I use 2 routines in the first, loading into memory 2 Sprites.

This function, reads the colors of the sprite 1 (1.png) and compares them with the sprite 2 (2.png), if they are different saves them in a txt:

Code: (glbasic) [Select]

4
840832112|843650153
1563106969|1568677516
-1893064546|-1887035245
-1524032099|-1517871729

4  -> is the number of different colors between sprite 1 and sprite 2
840832112|843650153 -> where 840832112 the first color of sprite 1 and 843650153 is the first color of sprite 2
1563106969|1568677516 - > where 1563106969 the second color of sprite 1 and 1568677516 is the second color of sprite 2
ecc...

Code: (glbasic) [Select]

LOADSPRITE "Media/1.png", 0
LOADSPRITE "Media/2.png", 1
LOADSPRITE "Media/3.png", 2


Code: (glbasic) [Select]

   GETSPRITESIZE img, w2,h2

   MakeImage(0, 1, w2, h2)


Code: (glbasic) [Select]


FUNCTION MakeImage: num%, num1%, width%, height%
LOCAL x%, y%, pixels%[], pixels1%[], memo$[]


   REDIM pixels%[width*height]

   REDIM pixels1%[width*height]

   DIM memo$[100000]

   SPRITE2MEM(pixels%[], num%)

   SPRITE2MEM(pixels1%[], num1%)

LOCAL abgr%

conta1 = 1
FOR y = 0 TO (height*width) - 1

      abgr% = pixels%[x + (y)]
      abgr1% = pixels1%[x + (y)]

IF abgr% <> abgr1%


FOR g = 0 TO conta1
IF memo$[g] = abgr% + "|" + abgr1%
GOTO giu
ELSE
IF memo$[g] = ""
memo$[g] = abgr% + "|" + abgr1%
conta1 = conta1 + 1
GOTO giu
ENDIF
ENDIF
NEXT

ENDIF
giu:

NEXT

test$ = "test2.txt"

OPENFILE(1, test$, FALSE)
WRITELINE  1, conta1  + "\n"

FOR g = 0 TO conta1
WRITELINE  1, memo$[g]
NEXT

   CLOSEFILE 1

 
ENDFUNCTION


The second Function seeks in the third sprite (3.png) the colors of the first column of txt and replace them with the colors of the second column:

Code: (glbasic) [Select]

GETSPRITESIZE 2, w2,h2
change_color(2, w2, h2)


Code: (glbasic) [Select]

FUNCTION change_color: num%,  width%, height%

LOCAL x%, y%, pixels%[], pixels1%[], memo%[]
LOCAL s, f$
LOCAL splits$[]


DIM memo%[1000000][6]

  test$ = "test2.txt"
OPENFILE(1, test$, TRUE)

READLINE  1, s
value_palette = s


FOR x = 0 TO value_palette

READLINE  1, f$

IF f$ = "" THEN DEBUG "Null" + "\n"
IF f$ <> "" THEN DEBUG f$ + "\n"
DEBUG x + "\n"
SPLITSTR(f$, splits$[], "|")


IF f$ <> ""
memo%[x][0] = splits$[0]
memo%[x][1] = splits$[1]
ENDIF

NEXT

CLOSEFILE 1




REDIM pixels%[width*height]
SPRITE2MEM(pixels%[], num%)

FOR i = 0 TO (height*width) - 1
FOR x = 0 TO value_palette

PRINT "X:" + x,220,140
PRINT "Y:" + i,220,160

//DEBUG x + "\n"
SHOWSCREEN

IF pixels%[i] = memo%[x][0]
pixels%[i] =  memo%[x][1]
GOTO esci
ENDIF
NEXT
esci:
NEXT

MEM2SPRITE(pixels%[], num%, width%, height%)
CLEARSCREEN

DRAWSPRITE num%, 0,0
SAVESPRITE "new.png", num%
SHOWSCREEN
 
ENDFUNCTION


Result: the sprite 3.png shall have the same colors of the sprite 2.png!

But everything is really slow! I do not have debugging turned on!

[Kyo]

now it works well!

In practice compares sprites 1.png and 2.png, and change the sprite palette 3.png, and creates the sprite 4.png

unfortunately does not work well with too many colors (I tried with 2000 colors).

I Attach the source if you want to try!

I did a rework of your (1st posted) code, just in case you want to see how it could be done in a more proper way and with faster execution speed. Hope that helps you:

Code: (glbasic) [Select]

LOCAL pixels%[], pixels1%[]
LOCAL w2%, h2%

LOADSPRITEMEM("Media/1.png", w2, h2, pixels[])
LOADSPRITEMEM("Media/2.png", w2, h2, pixels1[])

LOCAL abgr%, abgr1%
LOCAL memo%[]
DIM memo[10][2]

LOCAL conta1%, tmp% = w2 * h2 - 1
FOR y% = 0 TO tmp
abgr = pixels%[y]
abgr1 = pixels1%[y]
IF abgr <> abgr1
FOR g% = 0 TO conta1
IF memo[g][0] = abgr AND memo[g][1] = abgr1
BREAK
ELSE
IF memo[g][0] = 0 AND memo[g][1] = 0
memo[g][0] = abgr
memo[g][1] = abgr1
INC conta1
IF conta1>=BOUNDS(memo[],0) THEN REDIM memo[BOUNDS(memo[],0)+100][2]
BREAK
ENDIF
ENDIF
NEXT
ENDIF
NEXT


//// start of writing to file - this is not needed!
//LOCAL test$ = "test2.txt"
// OPENFILE(1, test$, FALSE)
// WRITELINE  1, conta1  + "\n"
// FOR g% = 0 TO conta1
// WRITELINE  1, memo[g][0]+"|"+memo[g][1]
// NEXT
// CLOSEFILE 1
//// end of writing to file
//
//
//// start of reading from file - this is not needed!
// OPENFILE(1, test$, TRUE)
// LOCAL f$, splits$[]
// READLINE  1, conta1

// DEBUG x + "\n"
// IF f$ <> ""
// SPLITSTR(f$, splits$[], "|")
// memo%[x][0] = splits$[0]
// memo%[x][1] = splits$[1]
// ENDIF
// NEXT
// CLOSEFILE 1
//// end if reading from file


LOADSPRITEMEM("Media/3.png", w2,h2, pixels[])
tmp = w2 * h2 -1
FOREACH p IN pixels[]
FOR x% = 0 TO conta1
IF p = memo[x][0]
p =  memo[x][1]
BREAK
ENDIF
NEXT
NEXT

MEM2SPRITE(pixels[], 0, w2,h2)
CLEARSCREEN

DRAWSPRITE 0, 0,0
SAVESPRITE "Media/4.png", 0
SHOWSCREEN
Btw. the part where you write to a file and read from it again is not necessary for it to work, I just included it here in case you need it for a different part of your program (uncomment it in this case).

Here's my attempt at a solution to a color changer - Hope you find it useful.
Click on the color to change. Set the new color in the ChangeColors function.
Images for this demo are attached.

Code: (glbasic) [Select]

// ------------------------------------------- //
// Project:     image_utils_6
// Description: Simple image color changer
// ------------------------------------------- //

GLOBAL px%[]   //buffer  - global to be seen by functions

LOCAL  mx,my,mbl,mbr
LOCAL currColor
LOCAL MBLDown = FALSE   //is mouse button-left down?

//load the image
LOADSPRITE "colorbox.png", 1

//load cursor
LOADSPRITE "cursor.png", 2


//main process loop
WHILE TRUE

//get mouse info
MOUSESTATE mx, my, mbl, mbr

//display input image sprite
DRAWSPRITE 1, 0,0

//get pixel color under mouse - if left mouse button is NOT down
IF NOT mbl THEN currColor = GETPIXEL(mx,my)

//draw a rectangle to show current color
DRAWRECT 450,20, 100, 100, currColor

//if left mouse button then change color
IF mbl AND NOT MBLDown
ChangeColors(currColor)
MBLDown = TRUE
ENDIF

//if left mouse button up, reset indicator
IF NOT mbl THEN MBLDown = FALSE

//draw mouse cursor - Always draw last to appear on top
DRAWSPRITE 2,mx,my

SHOWSCREEN
WEND

FUNCTION ChangeColors: color#
LOCAL width%, height%
LOCAL newColor = RGB(0,0,0) //color for replacement
LOCAL abgr%, r%, g%, b%, a%
LOCAL cabgr%, cr%, cg%, cb%, ca%

//break down color components
cabgr = color
cr = bAND(cabgr, 0xff)
cg = bAND(ASR(cabgr,8), 0xff)
cb = bAND(ASR(cabgr,16), 0xff)
ca = bAND(ASR(cabgr,24), 0xff)

//get sprite info
GETSPRITESIZE 1, width, height

//drop into sprite into buffer
SPRITE2MEM (px[],1)

//replace all occurences of color, with newcolor
//since the buffer is one long entity, we just loop through the data in sequene
FOR i% = 0 TO (width*height)-1

//break down sprite color components
abgr% = px[i]
r = bAND(abgr, 0xff)
g = bAND(ASR(abgr,8), 0xff)
b = bAND(ASR(abgr,16), 0xff)
a = bAND(ASR(abgr,24), 0xff)

//test and change
IF r = cr AND g = cg AND b = cb
px[i] = newColor
ENDIF

NEXT

//put buffer back into sprite
MEM2SPRITE(px[], 1, width, height)

ENDFUNCTION

Thanks kanonet and backspace 

Another question:
I tried to use the command setshoebox, I work well with sprites and music, but I do not read txt and ini is this normal?

[erico]

 
Good choice of sprites!
I love KOF and the XIII, altough not as tough as 98, scores high for me.

I´m particularly impressed on how they drew those sprites, I sense 3d was used for base movements and shadow renders, I think they drew over this first skeleton, I have to figure out. Beautifull technic

I could do without transparencies on the visual effects though...

[Kyo]

Can you help me make this code?

this is the map of the keys:

Code: (glbasic) [Select]

Key_p$ = "N"

IF KEY(205) THEN Key_p$ = "L"
IF KEY(203) THEN Key_p$ = "R"
IF KEY(200) THEN Key_p$ = "U"
IF KEY(208) THEN Key_p$ = "D"


IF KEY(30) THEN  Key_p$ = "A"
IF KEY(31) THEN  Key_p$ = "B"



If I press the button 205 - char L and press again in less than 1 second it print the string L | L

If i press the button 200 - chat R - and press the button 208 - char D ( less than 1 second ) and press the button 205 - char L ( less than 1 second )  it print the string  R| D|L

the string must contain a maximum of 4 letters: ->  R|D|L|A

I'm trying to store them in an array with a progressive timer, but does not works well!

Thanks for the help

Another question!
I have the same image in 2 sizes:

1) Width: 122 Height: 200 (122x200), 7.2 Kb, 24 Bit
2) Width: 122 Height: 200 (122x200), 7.2 Kb, 8 Bit 256 Palette

how much difference there is in runtime memory?

[erico]

I would think none, I heard GLBasic threats images as 24bit internally.

[MrTAToad]

If they were both BMP's then probably none.  However, PNG and JPEG may require extra memory for decompression...  How much would depend probably on any compression ratio...

[erico]

The png+alpha (32bit) might take a bit more too.
the png 24bit using the purple background color mask may use less mem too.

[hardyx]

I comme here every day, and now I know about the BT for iphone... 
Thanks hardyx... but it's you know if it's possible to connect an Arduno whit the Bluetooth of iPhone?¿, I think in the new model can be done, because the bluetooth it's the new SmartBluetooth, protocol or model, I'm not sure really what it's.

Here is the library for Bluetooth in iDevices. Like Gernot says, Apple allows you to use in games only.
