使用PyMem库通关Cheat Engine Tutorial (除最后一关)

Asss-whom

Cheat Engine的版本是7.4，之前有看到过对PyMem库的推荐，于是就写了这个来练一下手。
但我暂时没想明白如何用PyMem alloc 一片新的内存，所以就没有完成最后一关。
代码如下：

from pymem import Pymem

tutorial = Pymem("Tutorial-x86_64.exe")
base = tutorial.base_address


def first():
    pointer = tutorial.read_int(base + 0x325A70)
    address = pointer + 0x7F8
    tutorial.write_int(address, 1000)
    print("第一关修改成功")


def second():
    pointer = tutorial.read_int(base + 0x325A80)
    address = pointer + 0x7F8
    tutorial.write_int(address, 5000)
    print("第二关修改成功")


def third():
    pointer_health = tutorial.read_int(base + 0x325AA0)
    address_health = pointer_health + 0x818
    tutorial.write_float(address_health, 5000.0)

    pointer_ammo = tutorial.read_int(base + 0x325AA0)
    address_ammo = pointer_ammo + 0x820
    tutorial.write_double(address_ammo, 5000.0)
    print("第三关修改成功")


def fourth():
    address = base + 0x2CB88
    tutorial.write_bytes(address, b'\x90\x90', 2)  # nop nop
    print("第四关修改成功")


def fifth():
    pointer = base + 0x325AD0
    address = tutorial.read_int(pointer)
    tutorial.write_int(address, 5000)
    print("第五关修改成功")


def sixth():
    address = base + 0x2DB57
    # add dword ptr [rsi+000007E0],02
    tutorial.write_bytes(address, b'\x83\x86\xe0\x07\x00\x00\x02', 7)
    print("第六关修改成功")


def seventh():
    pointer_1 = base + 0x325B00
    pointer_2 = tutorial.read_int(pointer_1) + 0x10
    pointer_3 = tutorial.read_int(pointer_2) + 0x18
    pointer_4 = tutorial.read_int(pointer_3)
    address = tutorial.read_int(pointer_4) + 0x18
    tutorial.write_int(address, 5000)


def main():
    while True:
        step = input("请输入关卡数(输入b以停止):")
        match step:
            case "1":
                first()
            case "2":
                second()
            case "3":
                third()
            case "4":
                fourth()
            case "5":
                fifth()
            case "6":
                sixth()
            case "7":
                seventh()
            case "b":
                break
            case _:
                print("未实现!")


if __name__ == "__main__":
    main()
