First of all, you need to find out in which variable the game stores the value you need to change. For that, you need to enable Ren'Py console (in
renpy/common/00console.rpy
, then press Shift+O in-game to open it), and some knowledge of Python.
*
Then, you type in that variable name into the menu (“Variable” button). If you're not sure how to do it correctly, take a look at the example menu (use “Template” button to display it; “Clear” resets it back to empty), or look at the screenshots in OP.
After you're done, you need to
export the generated cheat menu mod, either by clicking “Install” and picking the location of
game/
subfolder of the game, or by clicking “Generate” and saving the text copied into clipboard in a
*.rpy
file within that same
game/
subfolder. If you're planning to modify the menu at a later point, you may want to copy its data into a text file (take it from “Creator” tab; to restore/load, click “Clear” then paste menu data into that same “Creator” tab).
The hotkey to bring up the menu is [K] by default (you can change it in the “Settings” tab).
* This step is obligatory: without knowing the name of the variable(s) that you need to change, you can't produce a working cheat menu. If you lack the skills necessary to find out the required variable names… Well, your only option then (other than requesting someone else to make a cheat mod for you) is probably to wait for a post I made yesterday to be approved – it provides a download for a tool I named LiveCheatMaker (made over last Sunday) which is basically inspired by Ren'Py Cheat Generator but remedies the issue with having to know Python to use it.
