Behind You.
This is a tutorial that is pretty advanced and because of that, I expect you to have a grip on regular IDA (normal instructions I mean, MOV, SUB, STR, etc). Of course it is not a requirement, you could just be viewing this tutorial out of curiosity. But it would really help to know some basic IDA before trying to hack vectors.



But what the hell is a vector? A vector is an instruction prefixed with "V". For example: VSTR, VMOV, VSUB, VCVT (convert), VLDR, etc. It is the instruction that you get when you set a watchpoint on a memory address that holds a float value. You will know that it is a float when iGameGuardian displays the number like "500.000000". Most of the time you be hacking VSTR, VSUB, and VCVT, at least in my experience.
