scripting, running function from app on delta about bit-slicer

[zorgiepoo]

Can you use the import bitslicer independently of Bit Slicer - i.e can you write standalone python apps that use the bitslicer library?

Unfortunately not possible. The scripting is pretty heavily coupled with the application.

I have extracted both the assembly code, and the HEX directly from the memory viewer. What would be cool is to take that hex code and drop it into a function in python, inside the execute function. Is there a way to do that, or is there a way in Python to call a function at a memory address?

This is not possible from the outside, directly. You may have to inject code in the process that executes the function, and have the game execute the code you injected. You may want to inject the code in a spot that the game executes frequently.

Have you verified that this function actually fires the pistol? Maybe you can try breaking on the function using the debugger, change the instruction pointer (aka "Jump to Instruction") back to before it's invoked (after it's been invoked once), and verify if it fires twice?

(For what it's worth, the code to Doom might be open source).
