Help/Support Help on where to start simple float hack

[mylesj 0 iPhone Xs Max 13.3]

I want to create a mod that edits some float values in call of duty mobile on ios 13.3 but not sure where i should start. Im able to find the mem addresses for the values  i want to change using igamegod and it successfully changes the FOV of weapons. Each weapon has a default FOV float value of either 44.00 or 57.00 and Id like to make a mod menu either in app or in ios settings app (whatever is easier) with multiple sliders that are attached to these values but im not sure where to start. Ive been looking at some of the tutorials but im not sure if the methods are outdated or not. I have theos, winscp, putty, lldb and ida freeware. Would i be able to easily do this by just following this and applying it to my situation? What would be different?

 

Im hoping someone might be able to point me in the right direction on what path i should take n i appreciate any help!

There's two ways you can go about this. The first method is probably the most beginner friendly, so you find what function writes to the fov with your watchpoint and then just patch the instructions at that address to set it to a constant value of your choosing. The second method would be to use instances (read the instance variable tutorial) to create a tree to that place in memory, since it changes everytime. This is done by a loop of watchpoints until you find a base, static address with which you can descend into the FOV.
