Cheat Engine:Memory Scanning
| This entry needs a lot of work. Please contribute if you can. Check this page to see if there are some suggestions for adding to Memory Scanning. |
Initial contribution, just placing a few 'things about ce scanning' here to work out later
Memory scanning is one of the most major features of CheatEngine. Memory scanning is reading the memory provided to the application. CheatEngine's scanning makes use of multiple processors when available.
CheatEngine allows you to search addresses in various ways using different types of searching.
Firstly you need to define what type of search you want. What you need to define is: Value Type, Scan Option, Scan Range and other smaller options.
Value Type
The available types CheatEngine can scan with are:
- Binary
- Byte (values between 0 and 255 or -128 to 127 if signed)
- 2 byte (values between 0 and 65536 or -32768 to 32767 if signed)
- 4 byte (values between 0 and 4294967295 or -2147483648 and 2147483647 if signed)
- 8 byte (values between 0 and 18446744073709551614 or -9223372036854775808 and 9223372036854775807 if signed)
- Float (values between 1.5 x 10^-45 and 3.4 x 10^38 )
- Double (values between 5.0 x 10^-324 and 1.7 x 10^308 )
- Array of bytes
- String (/Text)
- All (Byte to Double)
- Custom
Which one you should choose depends on the value you want to search.
A value that only switches between 1 and 0 is often a Binary.
While any integer number (1, 3, 4599, 15686, etc...) is most often a 4 byte value.
Strictly non-integer numbers are always Float or Double. Small numbers are often Float, bigger ones Double.
Text is often stored as a String/Text.
Scan Option
Sometimes you may not know the exact number of a value you want to search, or it changes too fast to scan normally. That's why CheatEngine provides several ways of looking for values. These scan options make it possible to find any value, wether you know it or not. The options available are divided in two: First Scan options and Next Scan options.
First Scan options are:
- Exact Value
- Bigger than...
- Smaller than...
- Value between...
- Unknown initial value
Next Scan options are:
- Exact Value
- Bigger than...
- Smaller than...
- Value between...
- Increased Value
- Increased Value by...
- Decreased Value
- Decreased Value by...
- Changed Value
- Unchanged Value
- Same as First Scan
All these options speak for themselves. CheatEngine remembers the values found in her previous scan, allowing it to compare new values with the old ones and revert to a previous scan. It also remembers the values of the First Scan.
Scan Range
CheatEngine only scans loooooooooooooool mouhahahahahaha you nuubb kelly i love you :)
