Hello AutoIt community I run into speed problem in my script wich i cant solve myself, problem is with decoding texture loop - for better explanation, you need extract from file pallete (16x 16 RGB color) and picture data (224 * 128 byte), then use correct color for your picture data.... nothing extra hard and also texture is quite small 224*256 it is for my car model viewer/later maybe editor GranTurismo 2 from Playstation 1, so its old dataformat and i cant understand why AutoIt take so long to decode texture when good old Playstation almost 2,5 decades old can do that nearly immediately (when you list through cars in shop or garage) My first atempt was create all trought dllstructure, because its easier approach, but it was soooo slow (40-50s for create textures) then i upgrade my routine via arrays, first 3D arrays later only 1D, next i put decoding colors outside loop but it is still not enough, my last version took cca 15s wich is still unacceptable for car model viewer when you click on one carmodel from listview (1100 cars for whole game) and you must wait 15-16s for model to load.... oh and i forgot mention some cars have more then 1 color (much more... 8-9-10 etc) soloading take 8-9-10 times more time in attachment i post texture file from GranTurismo 2 for one car (contain only 1 color) and also my dll struct version and array version code dll struct version - ± 40 sec (33 without saving) #include <FileConstants.au3> Global $IMDT[256][256][4] LoadTexture("ufs9r.cdp") Func LoadTexture($file) $fileHandle = FileOpen($file, $FO_BINARY) $header = FileRead($fileHandle, 0x20) ConsoleWrite("header> " & $header & @CRLF) $PAL = FileRead($fileHandle, 0x200) ConsoleWrite("PAL> " & $PAL & @CRLF) FileSetPos($fileHandle, 0x43A0, $FILE_BEGIN) $IMD = FileRead($fileHandle, 0x7000) ConsoleWrite("IMD> " & $IMD & @CRLF) $st = DllStructCreate("BYTE[512]") DllStructSetData($st, 1, $PAL) $struct_PAL = DllStructCreate("WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16];WORD[16]", DllStructGetPtr($st)) $struct_IMD = DllStructCreate("BYTE[" & 0x7000 & "]") DllStructSetData($struct_IMD, 1, $IMD) $start = TimerInit() For $i = 0 To 15 For $j = 0 To 223 $cn = 0 For $k = 0 To 127 $bt = DllStructGetData($struct_IMD, 1, $j * 128 + $k + 1) $blue = BitShift(DllStructGetData($struct_PAL, $i + 1, BitAND($bt, 0x0F) + 1), 7) $IMDT[$j][$cn][0] = $blue $green = BitShift(DllStructGetData($struct_PAL, $i + 1, BitAND($bt, 0x0F) + 1), 2) $IMDT[$j][$cn][1] = $green $red = BitShift(DllStructGetData($struct_PAL, $i + 1, BitAND($bt, 0x0F) + 1), - 3) $IMDT[$j][$cn][2] = $red If DllStructGetData($struct_PAL, $i + 1, BitAND($bt, 0x0F) + 1) = 0 Then $IMDT[$j][$cn][3] = 0x00 Else $IMDT[$j][$cn][3] = 0xFF EndIf $cn += 1 $blue = BitShift(DllStructGetData($struct_PAL, $i + 1, BitShift($bt, 4) + 1), 7) $IMDT[$j][$cn][0] = $blue $green = BitShift(DllStructGetData($struct_PAL, $i + 1, BitShift($bt, 4) + 1), 2) $IMDT[$j][$cn][1] = $green $red = BitAND(BitShift(DllStructGetData($struct_PAL, $i + 1, BitShift($bt, 4) + 1), - 3), 0xFF) $IMDT[$j][$cn][2] = $red If DllStructGetData($struct_PAL, $i + 1, BitShift($bt, 4) + 1) = 0 Then $IMDT[$j][$cn][3] = 0x00 Else $IMDT[$j][$cn][3] = 0xFF EndIf $cn += 1 Next Next saveTGA($i) Next ConsoleWrite("t " & TimerDiff($start) & @CRLF) ;
