 Posted: Fri Oct 16, 2015 9:17 pm Post subject: Scan and replace double value (again) |
 |
|
I read this function from mgr.inz.Player
| Code: |
function findDoubleValueAndReplace(findValue, replaceWith)
memscan = createMemScan()
foundlist = createFoundList(memscan)
protectionflags = "-W*X-C"
-- firstScan(scanoption, vartype, roundingtype, input1, input2,
-- startAddress, stopAddress, protectionflags,
-- alignmenttype, "alignmentparam",
-- isHexadecimalInput, isNotABinaryString, isunicodescan, iscasesensitive)
-- scanOption: soUnknownValue, soExactValue, soValueBetween, soBiggerThan, soSmallerThan
-- vartype: vtByte, vtWord, vtDword, vtQword, vtSingle, vtDouble, vtString,
-- vtByteArray, vtGrouped, vtBinary, vtAll
-- roundingtype: rtRounded, rtTruncated, rtExtremerounded
-- alignmenttype: fsmNotAligned, fsmAligned, fsmLastDigits
-- protectionflags: X W C (+ to indicate that flag MUST be set, - MUST NOT, * whatever)
memscan.firstScan(soExactValue, vtDouble, rtTruncated, findValue, nil,
"0","7fffffff",protectionflags,
fsmAligned,"4",
false, false, false, false)
memscan.waitTillDone()
foundlist.initialize()
for i=0,foundlist.Count-1 do
fullAccess( getAddress(foundlist.Address[i]) , 8)
writeDouble( foundlist.Address[i], replaceWith)
end
sleep(50)
foundlist.destroy()
sleep(50)
memscan.destroy()
end
--- used example
a=findDoubleValueAndReplace(0.01, -0.04)
print(a)
|
Question :
1. Is there any way we get/ filter scan result that exactly 0.01 ?
2. What is different protectionflags = "-W*X-C" / "-W*X*C" / "-W*X+C" ?
3. From Cheat Engine Help file:
| Quote: |
rtRounded : Normal rounded scans. If exact value = "3" then it includes 3.0 to 3.49999999. If exact value is "3.0" it includes 3.00 to 3.0499999999
rtTruncated: Truncated algoritm. If exact value = "3" then it includes 3.0 to 3.99999999. If exact value is "3.0" it includes 3.00 to 3.099999999
rtExtremerounded: Rounded Extreme. If exact value = "3" then it includes 2.0000001 to 3.99999999. If exact value is "3.0" it includes 2.900000001 to 3.099999999
|
Shown we can;t get exact value as we need (in this case 0.01).
How if we get all result scan first, put all as string, filtering the string for 0.01 and return it to number and last use it as replace value ?.
If possible, does any one should make a function for usage it ?
Regards

For that use a string instead of a number, and append few zeroes:
| Code: | | findDoubleValueAndReplace("0.0100000", -0.04) |
Or make scan for "array of bytes" type.
"7B 14 AE 47 E1 7A 84 3F" == 0.01 double

vtQword, ah yes need to try this also shall to try with vtDword.
Thank Zanzer for hint.
mgr.inz.Player, i did changed the double value 0.01 (AOB = 7B 14 AE 47 E1 7A 84 3F) to -0.04 (AOB = 7B 14 AE 47 E1 7A A4 BF)
I post this topic to get know a way how get exact value from scan double value if possible.
Anyhow, use
| Code: |
findDoubleValueAndReplace("0.0100000", -0.04)
|
also very helpful to reduce number of scan results found.
Thank you
