## Plant Vs Zombie (GOTY)

example as dll injection payload patching Plant Vs Zombie (GOTY) 32bit to never lost suns.

```rust
use winmem::{handle::Handle, patch::{BaseAddress, MemorySection, PatchHandle}, pattern::Pattern};
use windows::Win32::Foundation::{BOOL, HANDLE};

#[no_mangle]
#[allow(non_snake_case, unused_variables)]
extern "system" fn DllMain(dll_module: HANDLE, call_reason: u32, lpv_reserved: &u32) -> BOOL {
    return match call_reason {
        1 => on_process_attach(),
        _ => BOOL(0),
    };
}

fn on_process_attach() -> BOOL {
    let handle = Handle::default();
    let patch_handle = PatchHandle::new(&handle);

    let _ = patch_handle.apply(
        BaseAddress::Search(
            Pattern::from([Some(0x2B), Some(0xF3), Some(0x89), Some(0xB7)]),
            MemorySection::Module("PlantsVsZombies.exe"),
        ),
        None::<&[usize; 0]>,
        &[0x90, 0x90],
    );

    return BOOL(0);
}
