WMem

A basic Windows Memory Manipulation library, aimed at cheat trainers.

Usage Example

Obtaining a handle to the injected process

let handle = Memory::open_current_process();
/// ...

The same works for external usage, but via open_process_id

AoB Scan

// Unlike most other AoB scans, this also scans the heap memory.
// Use the 0x7F byte as a wildcard.
let name = Memory::aob_scan(&handle, b"John Smith").expect("AoB scan failed!").expect("Found no results matching your query!");
// ...

Writing

// Write "Johnny Smith" to the specified address.
let new_name = "Johnny Smith".to_owned();
// + 1 to get a null-byte at the end of the slice when writing it.
Memory::write::<String>(handle, address, &new_name, Some(new_name.len() + 1)).expect("Failed writing String!");

// Write 100 to the specified address.
Memory::write::<i32>(handle, address, 100, None).expect("Failed writing i32!");

Reading

// `read` returns a `Vec<T>` of the type specified for scenarios where you're reading
// an array of bytes.
// If you're just reading a value like `i32` or similar, grab the first entry and continue.

// Read the name of the entity with 32 characters being set as the max capacity.
let name = String::from_utf8(Memory::read::<u8>(handle, address, Some(32)).expect("Failed reading a slice of bytes!")).unwrap();

// Read the health of the entity.
let health = Memory::read::<i32>(handle, address, None).expect("Failed reading i32!")[0];
