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：

1. from pymem import Pymem
   
2. 
   
3. tutorial = Pymem("Tutorial-x86_64.exe")
   
4. base = tutorial.base_address
   
5. 
   
6. 
   
7. def first():
   
8.     pointer = tutorial.read_int(base + 0x325A70)
   
9.     address = pointer + 0x7F8
   
10.     tutorial.write_int(address, 1000)
    
11.     print("第一关修改成功")
    
12. 
    
13. 
    
14. def second():
    
15.     pointer = tutorial.read_int(base + 0x325A80)
    
16.     address = pointer + 0x7F8
    
17.     tutorial.write_int(address, 5000)
    
18.     print("第二关修改成功")
    
19. 
    
20. 
    
21. def third():
    
22.     pointer_health = tutorial.read_int(base + 0x325AA0)
    
23.     address_health = pointer_health + 0x818
    
24.     tutorial.write_float(address_health, 5000.0)
    
25. 
    
26.     pointer_ammo = tutorial.read_int(base + 0x325AA0)
    
27.     address_ammo = pointer_ammo + 0x820
    
28.     tutorial.write_double(address_ammo, 5000.0)
    
29.     print("第三关修改成功")
    
30. 
    
31. 
    
32. def fourth():
    
33.     address = base + 0x2CB88
    
34.     tutorial.write_bytes(address, b'\x90\x90', 2)  # nop nop
    
35.     print("第四关修改成功")
    
36. 
    
37. 
    
38. def fifth():
    
39.     pointer = base + 0x325AD0
    
40.     address = tutorial.read_int(pointer)
    
41.     tutorial.write_int(address, 5000)
    
42.     print("第五关修改成功")
    
43. 
    
44. 
    
45. def sixth():
    
46.     address = base + 0x2DB57
    
47.     # add dword ptr [rsi+000007E0],02
    
48.     tutorial.write_bytes(address, b'\x83\x86\xe0\x07\x00\x00\x02', 7)
    
49.     print("第六关修改成功")
    
50. 
    
51. 
    
52. def seventh():
    
53.     pointer_1 = base + 0x325B00
    
54.     pointer_2 = tutorial.read_int(pointer_1) + 0x10
    
55.     pointer_3 = tutorial.read_int(pointer_2) + 0x18
    
56.     pointer_4 = tutorial.read_int(pointer_3)
    
57.     address = tutorial.read_int(pointer_4) + 0x18
    
58.     tutorial.write_int(address, 5000)
    
59. 
    
60. 
    
61. def main():
    
62.     while True:
    
63.         step = input("请输入关卡数(输入b以停止):")
    
64.         match step:
    
65.             case "1":
    
66.                 first()
    
67.             case "2":
    
68.                 second()
    
69.             case "3":
    
70.                 third()
    
71.             case "4":
    
72.                 fourth()
    
73.             case "5":
    
74.                 fifth()
    
75.             case "6":
    
76.                 sixth()
    
77.             case "7":
    
78.                 seventh()
    
79.             case "b":
    
80.                 break
    
81.             case _:
    
82.                 print("未实现!")
    
83. 
    
84. 
    
85. if __name__ == "__main__":
    
86.     main()
