Help/Support How can i call & modify a fat binary file functions from a tweak?

[CosnotraLF 526 7]

i was wondering, how can make a tweak that calls  and modify functions from an app, like for example in minecraftpe binary file,  there is a function called "Pig::getMaxHealth(void)", it returns "0xA" , i know how to mod it using hex editor, but how can you make a tweak that modifies this function return?

 

extra info :

 

* Here is an image of the function that i want to modify:

* Im using IDA to disassemble minecraftpe binary file.

* minecraftpe version: 0.9.5

Actually, binary and tweak are different.

Binary can only be modify using IDA.

Tweak, can be add using 'code' which you will find it from FLEX.

I don't know if you can modify it from a tweak, but I'm pretty sure it can't

It didn't work , but your speed mod did. I don't get the code thou so idk if is correct or not. Whenever a Pig spawns, the game clashes and closes. Any fix for this?

Try setting another number instead of 99999..
