Cannot read float value

Question

trying to read float value but it giving error it says address must be int even though I use read_float and it makes an error it cant read it says address must be int

from pymem import *
from pymem.process import *

pm = pymem.Pymem("game.exe")

module = module_from_name(pm.process_handle, "game.exe").lpBaseOfDll

def GetPtrAddr(base, offsets):
    addr = pm.read_float(base)
    for i in offsets:
        if i != offsets[-1]:
            addr = pm.read_float(addr + i)
    return addr + offsets[-1]
northsouth = GetPtrAddr(module + 0x01B20C50, [0x38, 0x60, 0x290, 0x68, 0x140, 0x0, 0x3C])
print(pm.read_float(northsouth))



Traceback (most recent call last):

The read_float method tries to read a float from a memory address.
The address you specify must be an int – but you are passing a float.

Focus on the argument addr + i. Since you initialized addr = pm.read_float(base) it definitely is a float, and adding i does not change that.

So either initialize using addr = pm.read_int(base), or stay with reading a float but then you have to convert it to an int like so:

addr = pm.read_float( int(addr + i) )
