This is just a little Python script you can use to check if a Lua hook you seem to recall hearing about (or just want to exist) actually exists in Civ5.
Instructions:
To make this I took whoward69's post from the latest patch and made it into a little .csv file which the script reads from. He did all the real work here.
This currently won't give you the arguments you can get from the hook. Also it only works for GameEvent hooks, and not LuaEvents or Events hooks.
Instructions:
- Download and extract the .zip file to wherever you normally put your modding files. Make sure to always keep the .csv and .py files together.
- Double-click on checker.py to run the script. If a Python window doesn't open then download Python and then try again.
- When prompted, type in the hook you're looking for. Unless your entry exactly matches an existing hook, case and all, the script will return an error and usually a list of possible matching hooks you can choose from (meaning you can use this as a "Search Hooks" program if you like).
