and rounding type ?
For scanning you need:
- MemScan object, created with createMemScan()
firstScan method (from MemScan )
nextScan method (from MemScan ) (if needed)
- FoundList object, created with createFoundList()
waitTillDone() method (from MemScan )
initialize() method (from FoundList )
at the end you need "for-do-end" loop.

ok bro thx,you show me what i need and i will try combinate commands from here:
| Code: | | http://cheat-engine.googlecode.com/svn/trunk/Cheat%20Engine/bin/main.lua |
Edit:
i am combinate code somehow,and i get error and i dont understand where i put zero to change value of results:
| Code: | CEToLua = createForm()
CEToLua.height = 100
CEToLua.width = 240
CEToLua.caption = "Double scan"
CEToLua.centerScreen()
CEToLuaButton = createButton(CEToLua)
CEToLuaButton.caption = "Enable"
CEToLuaButton.height = 20
CEToLuaButton.width = 60
CEToLuaButton.top = 31
CEToLuaButton.left = 100
CEToLuaButton.onClick = function ()
memScan = createMemScan()
createFoundList(memScan)
memscan_firstScan(soExactValue, vtDouble, rtTruncated, "1.000000", "0" ,'0', '7fffffff',"-C" ,fsmNotAligned ,false ,false ,false, false, false);
memscan_waitTillDone(memScan)
foundlist_initialize()
end |

This will replace all 143.421 with 1234.5
in memory block with readonly protection flag.
| 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
function doit()
findDoubleValueAndReplace(143.421, 1234.5)
end
myForm = createForm()
myForm.OnClose = function () return caFree end
myForm.height = 100
myForm.width = 240
myForm.caption = "Double scan"
myForm.centerScreen()
myButton = createButton(myForm)
myButton.caption = "do it"
myButton.height = 20
myButton.width = 60
myButton.top = 31
myButton.left = 100
myButton.onClick = doit

-Writeable : is Unchecked
-Value : 1.000000

big thx bro  |
Look again at findDoubleValueAndReplace function, there is:
protectionflags = "-W*X-C"
So, maybe you need this:
protectionflags = "-W*X+C"
or this:
protectionflags = "-W*X*C"
Also, be careful with floating-point values (float, double). Scanning for "1, type double" will also find:
- 1.02
- 1.5
- 1.0725
- and if you are using roundingtype anything except rtTruncated, it will find 0.7
From Cheat Engine Help file:
| Quote: | roundingtype: Defined the way scans for exact value floating points are handled
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
|
So, better use this:
findDoubleValueAndReplace("1.000000", 0)
As you see, first argument is a string.

bit offtopic maybe, but i have question about this. how would i go about replacing all existences of 1234 with 6789?
for example i have decimal value of 1234 and i want to replace all of them with 6789.
currently i use AoB, but i have to convert all values to hex and reverse them, its pain. would be easier if i can scan + replace all values with a simple command.
thanks.
