Help/Support Help with hooking

[ZexorexKun 102 iPhone 8 Plus 14.6]

So i was trying to get a damage hack for a game. What i found was something called get_hitnumber which is supposed to increase the amount of hits i do. i tried changing it normally(by increasing the number) but didn't work then someone said that i need to hooking and some basic C++ to make it work and he already has the hack for it but won't tell me any further. So if someone know how to deal with this stuff then please help me. Thanks in advance. Also i am very new to this stuff. The only thing i know is to find the offset of something on dnspy and make increase/decrease it or just do bool true or false or NOP
